I’ve had this idea floating around my head after the YL commented (some time ago!) that the backlight on my DVMega/MMDVMHost Raspberry Pi was a tad on the … errr … bright side. She may have put it less politely but I soon agreed after I attempted to install it in the highest point in the… Read More MMDVMHost with HD44780 PWM backlight control
Sadly, this article from N6PSE of the Intrepid-DX Group has reinforced my belief that we, as radio hams, are our own worst enemies when it comes to furthering our hobby. After nearly 30 years in the hobby (20 plus of them licenced) I have yet to find an aspect of the hobby that hasn’t attracted some plonkers who… Read More The P5DX Story….
… a little over a week ago! (I’ve been having so much fun, I neglected to blog!) It finally arrived after a week of impatient waiting. Thanks must go to Karl, M0KSP for persevering through the flurry of successive firmware updates from Guus, PE1PLM to ensure I received a device with the latest firmware on-board… Read More The DVMega arrived …
It would seem the Phoenix DMR network, which is (was?) based on the DMR-MARC network with their warcry of “Motorola to the death”, is allowing both Hytera and homebrew MMDVM based repeaters and hotspots to connect. Could this be the reinvigoration that the network needs? Could this be too little too late? Don’t get me wrong, this… Read More Phoenix sees the light
Since moving to a new home QTH with restrictive covenants regarding antennas last summer, keeping on the air has been problematic to say the least! Most of my operation is currently accomplished using means that would make a radio purist cringe – internet linked repeaters I can access with a handheld transceiver. I have excellent line-of-sight… Read More DVMEGA hits the (DMR hot-)spot.
This is starting to become a running theme on my blog which may give the impression that I’m anti-DMR! Far from it – I fully embrace the mode and the possibilities it promises for the 21st Century amateur radio operator. I have NEVER owned or operated a D-Star radio, so I’m not a disgruntled D-Star operator bashing DMR.… Read More Way to go, CC-3…(NOT!)
The script in my last post was a quick hack ‘n’ slash to perform a few housekeeping functions on TLE files and transponder definitions for Gpredict in one go. I have since revisited the script, tidied it up a bit and made it more generic – it can now cope with multiple websites other than AMSAT… Read More More on updating TLE files for Gpredict
UPDATE [17 Feb 16]: See my post More on updating TLE files for Gpredict for a newer version of this script (but do read on so you know what it does!) Gpredict, the free, real-time satellite tracking and orbit prediction software from OZ9AEC is an excellent bit of software for predicting satellite passes if you’re into that sort of thing. One… Read More Update TLE files in Gpredict from more than one location …
Before I start, I would just like to say I have no axe to grind with those who provide the network infrastructure for the various DMR networks, many at their own cost for which I applaud. This post highlights just one example of the type of actions those pulling the strings take to manage the network… Read More DMR Addendum: A knee-jerk reaction from the Ivory Tower …?
…. Please forgive the unintended pun in the title! I first visited RAF Akrotiri as an Air Cadet in the spring of 1992 (before I was licenced and even knew what amateur radio was!) and can remember there being a rather active radio presence co-located with No 1 (Overseas) Sqn, Air Training Corps at RAF… Read More When antennae are left to the elements ….
