Ramblings of yet another nerd…
It took over a week, a complete network reconfiguration, and a lot of google searching to figure this one out. I wanted my MMDVM on P25 for a number of reasons. It should have been as easy as turning the mode on, and selecting a default host, right? well… maybe? It didn’t work that way …

“Your codeplug will never be complete” – a quote I saw on a site about amateur radio DMR codeplug generation. I’ll argue against that thought. I wish I could get all of the background info I wanted in here – but I haven’t had the training I would like. There are entire Motorola hosted courses …

Honestly, DMR is getting me excited about UHF/VHF amateur radio again. It’s not a NEW technology by any means, but the concept is really cool – I can have a drivetime chat with my buddies in Ohio, Alabama, and Iowa – assuming they have access to the repeaters. The biggest challenge was wrapping my head …

This is an old post, pulled from one of my older websites – at the time, i was going for a CLEAN install, and speakers were a problem for space – so here’s my solution. This was part of a series on the overall install, including the use of a Jotto desk purpose-built console (Vehicle …

occasionally at work, I have the need to perform some weak signal work, much like trying to get that last multiplier during November sweepstakes. At my previous employer, I let one of the technicians try out my Heil Proset Plus for listening work- he loved it. those headsets are made to be worn all day. …

After much experimenting and trial and error, I got almost all of the radio functions tested and working. I did run into an interesting problem, though. If I included ALL of the Icom CI-V enabled radios, and included 2 “spare” integers with the lookup structure, the Arduino would fail out after 180 items in the …

It has been a LONG time since I seriously did any C programming… and structures were something we only vaguely touched on in class. I’ve already used up about 60% of my dynamic memory – a huge chunk of it is the array of structures, containing a string, a hex byte, an integer, and 2 …

Well, I’m back to the Arduino <–> Icom projects. I just acquired an Icom 7300 – and found (according to others, as well) that it and the 7610 bury a lot of functions in menus that aren’t quickly accessible from the front panel… so now I want an external controller for my Icom 7300 – …

So – after moving, i was presented with a much smaller space to call my shack. Since my wife was working fomr home, we had to build her some office space. We arranged the space as an extra bedroom with walk-in closet. With this arrangement, she was only using the office during the daytime hours. …

Another “older” project I want to post now, just for others to benefit from my learning experience… For years, I’ve wanted a repeater to tinker with. Back as far as my time in Rolla, I’ve had most of the parts, but have always been short on the final steps. It all started with an interest …
