This update is long, long overdue. The network backend, and really the whole repeater network has seen a lot of changes since the diagrams were last updated. First off, the Topeka and Bashor machines were sold, and the Lawrence was Read more…


So there’s a new feature in MMDVM you say? Don’t want to wait for me to compile a new version for you? Never fear, I’m about to show you how to roll your own. To be clear, I’m talking about Read more…


That’s right. MMDVM now has native analog FM capabilities! I honestly didn’t think this would ever happen, but it has, and has been incorporated into the mainline MMDVM code as of a few days ago This will be a game Read more…


Here it is! The most asked for article and most often asked question since I introduced the STM32-DVM-MTR2K just over a year ago. Today we’re going to add an external analog repeater controller to an MTR2000 in parallel with an Read more…


This is a common question I’ve been asked about both the STM32-DVM-MASTR3 and the STM32-DVM-MTR2K. When I went digital, I went pretty hard core. I haven’t had a ham repeater controller for a few years now. My brother Gavin, N0ECQ Read more…


Folks, Due to the *continued* inappropriate content on the NoCO TGID 3171, it has been removed from the system. 0x49 DE N0MJS


I’ve had a few requests from folks who want to build their own STM32-DVM-MTR2K boards. While it’s not for the faint of heart, I have decided to make the necessary files available. This article is just as much a story Read more…


It took longer than I’d hoped, but I have just released a firmware update for the I/O processor on the STM32-DVM-MTR2K V2.0 boards. Those who watched it closely had asked the question why did I only connect 4 of the Read more…


This project has gotten a lot bigger than I ever thought it would. What started almost as a dare has turned into something very real. There has been a steadily increasing demand for the STM32-DVM-MTR2K, and while I said I Read more…


Folks, Tonight we completed the addition of NoCo 3171 to the list of dynamically linkable TGIDs on TS1. 0x49 DE N0MJS
