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.


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.

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.

The BitX 20 & More

The BitX

20160618_120709I was fortunate to recently have been gifted a BitX 20 kit by a friend and fellow VE. The kit came from QRPkits.com some time ago, I believe at least a year or so ago.

My intention was to build it for Field Day 2016. Sadly, while I was well on track to getting the radio built, 2 parts were missing from the kit. BS170 N-Channel MOSFETs to be specific. This put on the breaks for the final assembly and stopped me dead in my tracks with the finish line in sight.

20160624_193754I have the parts waiting for me at Jameco will-call for Monday. Once I get them home, populating the remainder of the circuit board should take about an hour. Then its on to the initial tuning and getting the radio packaged up in its housing.

I will do a full project write-up in the Projects section soon, but for now just an update.

A Homebrew Signal Generator/Oscillator

20160622_084953During the BitX build I ran into a small hiccough. The testing at some point calls for the injection of an 11 MHz signal. I would normally use my Lafayette signal generator but for some reason it’s on the fritz so I had to come up with another solution… build an 11 MHz signal generator.

20160622_085219With the crystals in the kit it was easy to build a simple generator with parts on hand and while I only had 1 of the five crystals installed it was easy. By the next testing phase I had installed the remaining 4 crystals. Now I need one for the homebrew SigGen! (click the image for the circuit diagram)

Off to HSC Electronic Supply for some 11 MHz crystals.

This project will also get a write-up in the Projects section soon. This one in in particular has a lot of use in checking unmarked crystals as long as they are between 1 and 20 MHz and is a great foundation piece for beginning builders.

A Homebrew TNC

20160524_145401Before I got started on the BitX I was working on getting my Baofeng 2m/70cm HT on digital. I found a couple of designs for a homebrew TNC and set out to make that work.

Because of the way the PTT key works on the Baofeng I haven’t been able to make the TNC work with the HT but it should work fine with my 40 meter QRPme.com Splinter II and the BitX 20.

A full write-up post is coming on this one too.

Look for all three of these in the Projects section for full details on the builds coming soon.

It’s been a long time since I posted, and most of that time I have been working on non-radio stuff. Now that I am back in the swing of things I have more time for radio stuff so I should be able to post more, and make updates to the Projects pages

As soon as the BitX 20 is up and running I plan on getting the Lafayette working again and get back to the Beach 40 DSB. Another Field Day has slipped through my fingers. I don’t plan on that happening again!

That’s all for now folks, 72, 73, and good night!
