Much Goings On

This first couple of months here have been busy. Building furniture, meeting new people, getting involved in the local radio scene. Trying to build the station up for HF operations.

Ham radio can be a lot of fun even as a solo practitioner, by that I mean working on your own projects. But the fun really kicks in when you are part of the larger community. There are opportunities to engage with fellow hobbyists and the community at large.

KBARA

The local radio club is the Klamath Basin Amateur Radio Association. I started off with the group as a VE for one of the clubs exam sessions and then a couple of events with the group, the Crater Lake Rim Run,  and a Safety Fair. We also had a work party up at two of the clubs repeater sites, Hogsback Mountain and Plum Ridge. The folks are very nice and I have been making a lot of solid radio contacts. Several of the members have been very encouraging in my EmComm endeavors.

The Community

CERT

I have been in communication with the Klamath County CERT group for a while and have been to one of the meetings, with another one tomorrow night.

Some of the KBARA folks are members of CERT as well so I’m not walking in blind or friendless.

I have turned in my County Volunteer paperwork and I’m just waiting to hear back. So, I’m not a member of the team yet, but things were looking good after the last meeting. We shall see.

NTS

I have wanted to get involved with NTS for a long time. In August I got in touch with the Section Traffic Manager to find out what I needed to do to get a local net going. After a few exchanged emails I started checking in regularly with two of the big Section nets that cover the whole state and several surrounding states, Beaver State Net, and Oregon Emergency Net.

After checking in to BSN and OEN for a couple of weeks I set up a local net, the Klamath Basin Traffic Net. Things are still very new and there hasn’t been much of a response yet, but that’s fine. It’s giving me time to work into it all.

I have had several opportunities to handle traffic from the net and I will start originating traffic once I work out a couple of issues in the station.

Skywarn™

I was hoping to get involved with Skywarn™ but the National Weather Service rep from Medford indicated that the local weather isn’t  that big a deal and the amateur radio presence in this area isn’t active or needed.  Without any support or interest from the served agency, there really aren’t many opportunities to serve. So, I guess I’ll just leave it at that for now.

The Station

There has been a lot going on with the station as well. After a couple of weeks of working the BSN and OEN with my low power, 5 watts, Yaesu FT-817 on the MFJ-1982LP end-fed antenna it was clear that I needed a bit more power to participate in nets, especially when the propagation conditions are bad.

I also needed to do something about the low power Baofeng UV-5R+ handheld transceiver I was using as a base station if I was going to be running a local net.

QYT KT-8900D

The mobile radio I have been using in the truck works very well, so it made sense to use the same radio for the base. This bumped me from a 5 watt HT up to 25 watts. The local net is running on a club repeater, and we do have a backup repeater as well and both have emergency power so 25 watts is fine for making contact throughout much of the southern part of the county.

The club has plans to link with other repeaters so we will have coverage throughout the county and beyond.

Diamond X50A

The homebrew J-Pole I was using would be okay, but it was limited to the 2 meter band and some of the repeaters in the area are in the 70 centemeter band. I needed something with a wider bandwidth and dual-band. Enter the X50A.

It was a simple task to swap out the twin-lead J-Pole antenna, which is now ready for my go kit, and put the X50 in its place. The X50 is also a commonly used antenna for amateur repeaters so it is reliable and can handle more power than I am putting through it.

ICOM IC-718

I mentioned the need for more power on HF. The solution that presented itself was an ICOM IC-718 that one of the club members wasn’t using and was willing to sell. The radio is rated to 100 watts which

The radio is rated to 100 watts, which has been helpful, though the last month band conditions have been crap making 5 watts nearly impossible and even at 100 it’s been difficult.

Initially, I only had the MFJ-1982LP antenna for HF that would cover 80 meters. The LP stands for Low Power, it can only handle 30 watts so when I first started using it I had to keep the power down low making it only a little better than the Yaesu FT-817.

Hy-Gain AV-18VS

The AV18VS is a nifty multi-band antenna that covers 10-80 meters. It uses a manually adjusted inductor to tune the various bands. Since the coil is at the base of the antenna, it’s not practical to get it way up in the air. In fact, it is intended to be used 3-5 feet above the ground. I have mine set at a little over 5 feet but it has a really good ground right under it.

It will likely be less convenient when the weather turns and we start to get snow. I plan on building some kind of hat to keep the snow off. I am still thinking that through.

Mobile

I have been running mobiles since July. I installed a QYT KT-8900D, a Midland MXT400 GMRS, and Uniden BEARCAT 980SSB CB when we first moved. Noone up here uses CB, but there is a lot of ham and GMRS traffic so I ended up pulling the CB.

I had always intended to install permanent mount antennas but it wasn’t practical at the time, which worked out well since I am driving a different vehicle than I started out with.

After getting the new (to me) truck in July I mounted a shelf that replaces the visors, the Vertically Driven Products Shelf-It. This works out great for holding radios and other stuff. We used to install these in all of the tow trucks when I drove tow.

I don’t use the visors, and with them mounted on the Shelf-It it’s hard to see traffic lights, so I just left the visors off.

Yesterday I finally got around to installing the NMO mounts in the roof of the truck. I installed three, one for the QYT KT-8900D, one for the Midland MXT400 GMRS, and a third possibility for the Yaesu FT-817 so I have a mobile HF rig. The only mobile HF antenna I have right now is for 6 and 10 meters. The nice thing about NMO antenna mounts is that they are easy to cap off and use later.

Below are some pics of the NMO installation.

Having the mag mounts on the roof with feedlines crushed through the window gap is just ugly, not to mention it does horrible things to the feedline.

Construction always starts with a bit of demolition. In this case dropping the headliner. I only needed to pull down one side so that’s what I did. It required pulling the Shelf-It out and removing the door trim pieces around the entire door as well as one coat hook and the cab light.

Here I have the back mount installed already and you can see the two 3/4″ holes for the other two.

It looks like quite the mess, but it’s really pretty simple. The white jar on the left is Chemplex silicone grease to coat the weather seals on the connectors and antennas or caps. Clockwise, the punch tool with a box open-end wrench and Allen wrench cuts the holes, in the large bag is a mount with cable just like the one just to its right. The small bags and black cap in the center are covers for the mounts when no antenna is attached. On the rag are needle-nose and slip-joint pliers to tighten the mount down. The brass disk is the installed NMO mount.

Three antennas installed. The front left is the dual-band ham antenna. The one on the right is for GMRS. The stubby one in the center is also a dual-band ham antenna I wanted to check out, a little performance comparison. The NMO mounts are much cleaner than the old mag mounts. I can still use the CB or any other radio that I can get an antenna with an NMO base. My CB antenna does. The advantage is I can move antennas or radios easily.

My apologies for the blurry picture, the camera kept focusing on the near headliner. The radio on the left is the QYT KT-8900D and the one on the right is the Midland MXT400 GMRS. The mics and cords stow on the shelf and there is plenty of room for more radios. I used the holes in the headliner from the visor clips for cables coming out, power on the left just behind the GMRS radio and antenna cables just to the left of the center hump.

Things Upcoming… too much to go into, how about some keywords.

Pi TNCs plural, radio go box, more homebrew antennas, homebrew filter cavities for a repeater, much more digital mode…

Until next time, 73,

The Move Is Done

Well, sort of…

We are here in Klamath Falls, Oregon now. We started the move July 1st and I was making runs all July. The old place was officially vacated July 31st. August was the slow unpacking of boxes and the beginning of several furniture building projects. I have built 6 bookcases; 2 of them 40 inches tall, the other 4, 70 inches tall.

I still have a number of things to build like the DVD cabinets that will hold our 1000ish movies and TV shows. I also have a lot of storage containers to build, think apothecaries drawers. Lot’s and lot’s of them.

You can see why I haven’t posted in a while. I have made some upgrades to the shack, well the mobile, the shack is looking rather minuscule right now.

I have absolutely no bench space for shop stuff or electronics. The station is occupying a puny 1 sq.ft. space across 2 shelves, but, I actually have an HF antenna outside! The MFJ-1982LP endfed is up. The feed point is about 15 feet up on the mast my 2m roll-up J-Pole is attached to and the rest of the antenna is supported by 2 31 foot Jackite poles and 20 feet up into the Ponderosa Pine in our front yard.

So far 80 and 40 meters have been kind. The net controls have had to work me pretty hard, but I have been getting through. I have been heard as far away as Victoria BC Canada, La Jolla California, Somewhere in Wyoming, Utah, and Nevada. Not bad for 5 watts.

The power on the base, my Yaesu FT-817ND, needs a boost now that I am putting together a local NTS Net. I need to make the Local to Section hop on HF more reliably and not make control work so hard. The local net will be on one of the club repeaters.

I have also moved forward by getting involved with a local active club, the Klamath Basin Amateur Radio Association. I have already done two events and a VE session with the club since we got up here. Also in the mix is getting started with the Klamath County CERT program.  There is some early work on getting an ARES/RACES group together. All kinds of fun going on.

Once we got up here I started work on the mobile. The Baofeng UV-5RE+ was not cutting it on 2 meters. I upgraded from 5 watts with a crappy little antenna to 25 watts with a QYT KT-9800D dual band mobile radio and an ANLI DC-124H TriBand antenna.  Much better performance. Also in the mobile, I installed a Uniden BEARCAT 980SSB Single Sideband CB and a Midland MXT400 GMRS radio. There is hardly any CB traffic up here, but surprisingly, there is quite a bit of GMRS traffic.

For a 2 meter base, I have been using one of the 5 watt handhelds attached to the homebrew 2 meter twin-lead J-Pole I built a while back. Now that I am getting hooked up with CERT, I think I should pull the J-Pole out of the PVC and use it as a portable roll-up. I also need a little more juice for poor weather conditions so a 2 meter base upgrade was in order. Another QYT KT-9800D mobile radio and a Diamond X50A dual-band base antenna should work nicely for VHF/UHF. Those will be incorporated into the station by the end of the week.

As for the HF side of the station… I need to poke around for something around 100 watts, which will require an antenna upgrade too. The MFJ-1982LP is only rated to 30 watts. As long as I keep the power down I should be able to use it for a while. That will still give me a 6 db power gain over the 5 watts I am pushing now. Anything should help. The section nets are on 80 and 40 meters so I will need an antenna that covers at least 10-80 meters. 100 watts should be more than enough for my needs.

Oh, one other thing, I finally got my Skywarn ID number, now I need to find a net for Skywarn. I haven’t found anything in southeastern Oregon yet. I’ll keep looking.

Anyway, that’s the status update for now. Look for an NTS page to be added to the site soon.

The Move Is On!

The move is most definitely on, things happened quickly and we put down a deposit on a rental house while we were up in KF two weeks ago!

We have been packing since early April so most of our stuff, aside from consumables and the essentials, are packed. I will be making a number of runs up to the new house in Klamath Falls, Oregon (CN92de) beginning July 1st.

We decided to buy/build a trailer rather than rent a truck. The cost will work out about the same but in the end, we will have an asset, not just a receipt.

This weekend, June 24-25 is trailer build time, so another Field Day goes by unobserved… Sad about not getting the new FT-817 on the air for FD, but the move takes precedence. The good news for radio is that I have a place to set up a 136′ multi-band horizontal end-fed with the mast just a few feet away from the shack’s new location.

Also in radio news…

When I designed my QSL cards, we were already looking at relocation sites in Oregon so I designed a card for California and a card for Oregon with the intention that I would only have a couple of minor changes to make once we found a place. With any luck, in a couple of years when we find our permanent landing zone it will be in the same Grid Square. If not, it’s an easy fix.

 

 

 

 

Since I design my QSL cards myself, I use VistaPrint for the printing. I get a high-quality stock and finish, it’s economical, and I maintain complete control over the printing.

Another early prep purchase was my VE/Callsign tag. Moving to a new Division, I figured I would be a good idea to get a badge with the new division on it.

I get all of my badges done by The SignMan in Baton Rouge, LA. I have nothing but great things to say about Rick. He does an excellent job and the customer service is top shelf all the way. I am not affiliated with the shop or Rick in any way, and I buy my stuff at the regular price, I just love the quality, speed, and work ethic. You will too I’m sure.

I am hoping to get the FT-817 rigged up for mobile use in the next few days so I will be able to work mobile on 70cm, 2m, 6m, and 10m over the many long drives to OR and back. I will post frequencies on the contact page and in a sidebar element.

Along with adding a Remote Pilot certificate to my FAA credentials, I added a General Mobile Radio Service (GMRS) license grant to my FCC credentials. The new license is WQZJ382. At present, I only have a single handheld GMRS radio (Garmin Rhino 120) but I have plans to add a Midland mobile to the vehicle and one at home once we get set up in Oregon. Most likely a couple of handhelds as well. I am also entertaining the possibility of a repeater.

Well, that seems to be it for now. Until next time…

In the works

Mid May, two months since the last post. What have I been up to?

Of course, I have been doing the regular VE sessions, but other than that… Packing. Lots of packing. We have been planning on relocating for several years now but time has finally arrived that we are moving forward pun intended.

We don’t want to move in the winter and we don’t want to wait another year so… we are gearing up for a move sometime soon. One of the best ways to get ready is to start filtering through all of the stuff that has accumulated over the last 21 years we have been here.

As we shed truck-loads of stuff we just don’t need to Savers and Goodwill, we have been packing up the things we can do without for a few months. Having a bunch of other stuff on the brain, the ham shack, or most of it anyway, was one of the first things to get boxed. So for now, no electronics lab. Nearly all of my test equipment is boxed up. We are up to 40 boxes, filtering and packing more every day.

Lest you think I’m ignoring radio, I have been gearing up to be more active in ARES, RACES, NTS, Skywarn, and CERT by taking a lot of FEMA/DHS classes that are prereqs for various organizations. I am also scheduled to take a BLS class in two weeks which includes CPR, AES and more. I want to add a variety of EmComm instruction to my growing list of classes offered in the near future so I am ticking down the long list of prereqs and associated training.

In a somewhat side related area, I also recently acquired my Remote Pilot certificate with Small Unmanned Aircraft Systems rating. Basically, a commercial UAV pilots license in addition to my commercial airplane pilot certificate. This will allow me to do aerial photography and inspections for pay with a UAV/UAS. And what might I be taking pictures of and inspecting, radio towers???? Possibly.

Anywho, I wanted to post an update so you didn’t think I had abandon radio or the site. I just don’t have a lot to post about other than classes and ratings. I will be doing a mobile install of my FT-817 with a quad-band antenna sometime soon so I will plan on posting about that soon. I may also be posting some short subject videos in the near future as well.

Til next time, 73

Online License Classes

Something I have been working on for some time now is an online Amateur Radio License Class program. The biggest issues I have been hammering away at are the platforms for designing an effective learning experience along with what I believe to be the inherent drudgeries of traditional online learning.

As a student, I have taken a number of online classes at the college level and found myself not getting much from the class. The lack of instructor involvement and the spontaneity of live Q&A and lectures makes the whole process less conducive to learning anything new or enjoyment of the process. At least this has been my experience.

I certainly don’t want to put my own students through this kind of class, and as of yet, I hadn’t been able to get a group of platforms to work together seamlessly enough to make the whole thing look like a professional endeavor.  Believe it or not, I don’t enjoy teaching when I feel like the whole process looks slip-shod.

As an Instructor, I have had some experience with online course development and publishing. I ran into many of the same frustrations I had as a student while working on the other side of the fence and it frustrated the heck out of me.

The Environment

I think a good online learning environment incorporates a number of approaches.

First. A solid self-paced, resource rich, modular, study and quiz environment. This is the framework everything else is built around. If the bones are in good working order you can bulk up the flesh as needed.

Second. Community and communication. Students need to be able to interact. Most college online classes force community with journal style public entries or simple questions that require minimal engagement to complete the module.

Forcing community is tough, particularly when everyone is completely time-shifted. In live classes the first few hours, up to much of the first day, everyone is fairly lone-wolfing it. By the end of the first day, people are interacting. By the time we get to exams, there is some genuine comradery. It is great to see this develop.

Communication takes many forms. In forum type activities it takes a long time to develop any active communication. Instant messaging type systems encourage a more active participation but are difficult to maintain when people are active at different times.

Simple easy to use communications platforms are needed to develop an active community environment.

Third. Live, interactive events throughout the course. Lecture, Q&A, any active engagement is good. A combination of both Lecture and Q&A with a bit of time for general conversation or sharing is a great way to encourage both regular communication and sharing.

This has generally been the hitch on the whole thing. Live interaction requires several things, a visual component and an audio component as well as ease of use, and free or incredibly low-cost.

Platforms

The Framework. I like the Moodle platform as a foundation. It offers a lot of options and incorporates planned lessons, resources, and quizzing, along with a really flexible back office system that has been proven over time. It’s a free platform, and it is used by colleges and universities all over the world.

Presentations & Communication. There are a lot of options for sharing presentations, mostly for collaboration, and there are webinar type programs as well. I recently became aware of FreeConferenceCall.com; I like this one because it allows me to do a broad screen share or select specific windows. It also includes video conferencing, VoIP conferencing, and dial-in conferencing, and text messaging, all in one package with all of the features being concurrent.

FCC, not to be confused with the government agency, seems like a good option for the communications element. There are of course other VoIP and messaging options that would work quite easily alongside FCC as just the slide/whiteboard presentation. For VoIP, solid choices include Skype or Google Hangouts. Both also have a text messaging component as well.

There are other options including live casting with YouTube. Third party software with YouTube can easily meet the presentation needs, but the learning curve for me while building the program in Moodle would be steep.

Conclusion. I am by no means set in stone with any of the options. I am leaning towards Moodle + FreeConfrenceCall, with maybe an outside text messaging option.

Any way you slice it, I have a lot of work to do.

Until next time, 73,
~Jon KK6GXG

ETA (6/25/2017): The Ham-U.com domain is now dead. I let it go because I just don’t know when I will be able to get to setting up the online program. When it does go live, it will be part of the KK6GXG domain.

Another successful class

Just a short post today. This weekend I held another Technician license class, and it went great!

Another small and diverse class, best of all everyone passed with flying colors. I really do have a lot of fun doing these; by Sunday evening I am wired, completely exhausted, and absolutely fried mentally, I love every minute of it.

Two more classes in April, one Technician and one General, and that ends my currently posted calendar. I may be adding more classes after a visit from out of state family. We shall see.

In other radio news, I have been busy building dipole antennas. I am up to a 6 meter, 10 meter, and a 20 meter. I will definitely be adding a 40 meter to that soon. I have been looking for steel materials suppliers for 1/4 λ verticals. I want to build individual 70cm, 2m, 6m, and 10m. I think I may have found one. If so I will be working on a vertical array in the near future.

After I get all of the bands covered with basics, I want to start working on directional beams, at least for the main bands. I will wait for a while on these. Down the road, I also want to build some of the more exotic antenna varieties, including multi-bands, and arrays.

Antennas are usually relatively quick builds, which is great. Radio builds tend to take a bit longer. I have a couple of radio projects in limbo at the moment. Once I get some cabling projects finished for digital modes, I will also be getting back to the radio projects.

The build that seems to be taking forever is the Beach 40 project. This one needs to get back on the priority list. I should be able to get back to it this fall.

In VE news… This weekend will be my 54th VE session with the Silicon Valley VE group, something else I truly enjoy doing.

That’s it for now.

Where do we go from hear

ARRL Registered Instructor

Good Technician class this last weekend. Small, but a lot of fun. The best part of all was the 100% pass rate for the exam.

Okay, now the confession, it was a two student class. Still, I am happy about the two newly minted hams.

Last weekend was a VE weekend, so I was examining not teaching. As is the norm, when we are not grading exams, we jack-jaw. Mostly about radio operations, sometimes the conversation leans technical. In recent months we have been haveing

In recent months the chatter has been about the ham population. Two specific areas have topped the conversations. The first is centered on the retention of Volunteer Examiners and engaging the VE community.  The second topic of conversation has to do with a special anniversary coming up in a few days.

February 23, 2007,  was the date the FCC dropped the CW (Morse code) requirements from all amateur radio licenses. Back in February 1991, the FCC dropped the code requirement for the Technician class license but it was the 2007 removal of code that made it upgrading a no-code Tech possible.

There was a boost to the number of new hams in the early 90s, but the number of new hams, and upgrades, since 2007 has been record breaking.  So this is all great news for hams right?

Well, maybe. The truth is, there is no telling what’s going to happen. Part of what makes this an interesting subject is that we don’t know why all these new hams have been drawn to amateur radio.

There are a number of possibilities, some centered around the huge and ever-growing population of DIYers and Makers, many of whom show interest in RF, at least on some level. There are the growing number of drone enthusiasts; some need a ham license to control the aircraft itself, others are looking for telemetry, and/or looking at RF video feeds.

What does someone’s reason for becoming a ham have to do with anything? It has to do with retention. Ham licenses are valid for ten years. That’s a long time. Someone who is deeply invested in the hobby is more likely to renew their license. Someone who is involved at a more casual level is less invested and may not feel the need to renew.

Here we are. It’s now ten years later and the first upgrades without a CW requirement are beginning to expire. The big question is will they renew.

My hope, of course, is that the attrition rate will not grow at the same pace as the influx of new hams over the last ten years. Only time will tell.

New Classes Posted

Welcome to 2017!

ARRL-VEC Volunteer Examiner

Not to put too fine a point on it, 2016 had a few issues. Too many beloved performers became silent keys, and more than a few other things that will affect us all went a bit sideways. I’m not even going to get started on politics.

To start the year off on a positive note I worked a VE session in the morning January 7th and spent the rest of the day putting together a new class schedule for Technician and General classes licenses and getting started with the promotion work, posting classes and prepping presentations.

Registered W5YI Instructor

I have six classes coming up, 4 Tech and 2 General January through April. All of them are 2-day weekend classes. This time around I am using the W5YI books by  Gordon West instead of the ARRL books. My main motivation to switch books is Gordo’s reorganizing of the FCC questions into a more logical order.

While the change will save time in class, I now have to tweak a lot of slides. There’ll be no time savings on the prep side this go, but I am optimistic that the reorg will make things a lot smoother in class.

ARRL Registered Instructor

If you, or someone you know, is interested in getting their ham radio license or upgrading from Tech to General and they are local to San Jose, please pass along a link to my site. Classes are listed here.

All of the classes have been posted to both the W5YI and ARRL class listings. As I write this, they are the only classes listed in the south Bay Area. The closest classes on ARRL’s list are San Francisco and Sacramento. There are no classes listed for the area on W5YI. They won’t show up until Monday or Tuesday (2/9-10) because all class postings need to be approved by a human.

I am hoping to greatly expand my teaching and hosting exam sessions later this year. All things in their time.

Happy Holidays

Happy Holidays from KK6GXG!

It’s been a long year. Some plans played out, others didn’t. In the end, the things that did play out were long time goals. Those that didn’t pan out where short term and are still in the mix for future completion.

On the plus side, I did manage to get a bunch of VE sessions into the schedule this year. 27 so far with one more next Saturday for a year total of 28 sessions. That makes a grand total of 46 since I started as a VE.

Another plus was finally building a crystal set. It’s one of those things lots of people build as kids and most builder hams have done them as well. I hadn’t until now. It worked out well and I could hear several stations. In the future, I plan on building different variations and working on fine tuning them.

2017 promises to be an interesting year filled with many new builds, completion of some projects, and a lot of operating.

In the meantime…

Happy Holidays to All

July? Has it really been that long?

Wow, yes it has in fact been that long.

20151104_161606From a building stand point… nothing new has been going on. I am still working on the Beach 40 and the Bitx 20. The Beach 40 still needs the audio section rebuilt and the Bitx20 needs some troubleshooting . I don’t have the facilities to put up a 20 or 40 meter antenna and since both radios are QRP(p), a good antenna is vital to making any contacts.

20151121_072647From an operators perspective… ya, nothing going on there ether. I need to pull down my Frankenstein/Hill Billy mast because we are having our building painted soon. I have plans for a simpler replacement that should work out fine. I’ll post about that if and or when that happens.

From an experimenters view point…  I have been kind of busy lately. Many of the newer radio projects I have been looking at use micro-controllers and embedded Linux systems. All of which I am totally fine with. There are so many other applications besides radio that I can employ these technologies. The only impediment is getting some play time in with these technologies and getting familiar with there capabilities, use, and programming.

arduinoEarlier this year I picked up some Arduino hardware. I haven’t had much time to work with it yet as the Day Job has been keeping me hopping as well as a lot of stuff in the personal life, nothing bad, just a lot of changes and preparations.

Many projects are done with the Arduino and various shields. Some require a little more direction in the form of an embedded system with a true OS. Enter Raspberry Pi and Raspbian.

rpi3bLast week I added a RPi 3B to the hardware pile and began working with it. Along with the Pi I picked up a copy of Exploring Raspberry Pi: Interfacing to the real world with embedded Linux From Wiley written by Derek Molloy.

Linux doesn’t worry me at all. Many moons ago I was a Solaris 7/8 admin as well as a RedHat 7 admin. The problem is that well over a decade has gone by since I actively worked on those systems. I have been in a Windows only environment for so long my Unix brain has turned to mush. So now I’m re-learning the Unix command line and re-acquainting myself with the Linux directory structure along with some all new unique elements of embedded systems and the Raspbian OS in particular.

With all of the projects piling up and now adding a lot of general computer stuff to the pile, Arduino Sketches, Python, C/C++, and picking up where I left off with Perl, it almost feels like I should go back to school and get credit for all of this work. I could pick up a CS degree with everything on my “tech to learn” plate right now. Add in all of the projects and an engineering degree (EE or ME) isn’t far behind. Thoughts for another time.

Radio specific plans are to read and build along with Crystal Sets to Sideband by Frank W. Harris W0IYE, and then get back to Experimental Methods in RF Design and do the same. I don’t expect to do a lot of operating other than 2 meter until we have the facilities to put up a real antenna, and there is no solid timeline for that.

Life outside radio has taken all of my time lately and I am just now slowly getting back to things. Most of it is general electronics/computer experimentation and adding to the knowledge pool right now.

So in conclusion, no I haven’t been busy, I’ve been too busy.

hamverseryP.S. Today’s post is brought to you by Hamversary. On this day in 2013 I received my license grant about a week after I walked into the Saratoga Fire Station a non-ham. Since then I have worked my way up to Extra Class, begun teaching license preparation classes to prospective hams, and I have been a Volunteer Examiner for 42 exam sessions, most of them at the Saratoga Fire Station.

I have learned so much in so many ways in this short period of time. Thank you Amateur Radio.
