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.

First week of May

First week of may, and ain’t got much to say!

JT65JT9No build projects progressing, not much time OTA, none actually, but I have managed to get some reading in. I picked up a copy of one of the new ARRL books Work The World With JT65 and JT9.

Not bad, a short read, though I must admit, I don’t really see myself using the TJx mode any time soon. It looks like its pretty much a contesting mode. I’m not much interested in contesting until I get more of a station built up, and even then… I dunno.

HighSpeedMultiMediaWith some luck the UPS guy will bring me the also new ARRL book High Speed Multimedia for Amateur Radio book today. I still don’t have a TNC or HF radio up and running, but I do have some spare/old 802.11 units lying around… hmmmmmm…

There could be a project with HSMM on the horizon.

RTTY-PSK32I also have a copy of RTTY/PSK31 for Radio Amateurs 2nd Edition on the way which I think will see more action in the near future than anything else. I have a USB/Serial cable and enough toroids and cabling that I might fourgo the TNC a little longer and build an interface myself just to see if I can get it up and running.

The down side is that I will still only be running whatever digital mode on 2 meter FM rather than SSB, but that will get resolved at a later date.

ARRL-VEC VEIn other news, there is another VE session tomorrow (Saturday, May 7, 2016 08:00-10:00) at the Saratoga Fire Station. This session will be my 30th VE session!

Also this month, Maker Faire is here in San Mateo and I will be working both the morning and afternoon VE sessions at the faire. More info is available on the SF Bay Area Maker Faire VE Session website.

One last thing. I’m not going to post it yet, but since we have been planning on relocating, I worked up a new QSL card to reflect the new location. Once we are confirmed with a new QTH and Grid Location I will post a preview of the new card. Speaking of which, if you would like a QSL from my current QTH email me with your address and I will send one out right away.

Oh, one more thing… I am back to studying for my RADAR add-on to my commercial license.

I guess I have been doing stuff.
