... Found out a deep Nintendo Switch case fits my TX-500. Have the radio mounted via velcro to the shelf, which will tilt to different angles. Underneath, there is enough room for a 4.5Ah Bioenno, power cable, 61' wire (which is resonant on 40 and 20 with my Spark Plug EFHW), Digirig w/ cables, and mic. In the lid, I keep a couple RG174/316 jumpers, the Spark Plug, and some other odds and ends. Buttons up into a nice compact unit for tossing in my SOTA pack. I can run that radio 9+ hours on that particular battery. Removing all the cables and such from that compartment allows me to store two them if needed.

... How to compare radios One of the topics I've been talking about lately is the idea that we might be able to measure the performance of your radio in some meaningful way using equipment that can be either obtained by any amateur, or by introducing a process that allows results to be compared, even if they have been generated differently. Recently I came up with a tool that automatically generates a spectrogram of an audio recording. That on its own isn't particularly interesting, but it's step one in the processing of an audio signal. In addition to the spectrogram, I also created a tool that generates a tone frequency sweep, think of it as a tone that changes frequency over time, let's call it a sweep. If you combine the two, you can generate a spectrogram of the sweep to give you a starting point or baseline for comparison. You can build on that by using your radio to transmit that sweep and record the result using a receiver. In my initial experiments, I used an R

... ARISS contact scheduled for students in Denzlingen, Germany Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact with astronauts.  ARISS  is the group that puts together special amateur radio contacts between students around the globe and crew members with ham radio licenses on the International Space Station (ISS). This will be a direct contact via amateur radio. Students at Erasmus-Gymnasium Denzlingen, Denzlingen, Germany AND Goethe-Gymnasium, Freiburg, Germany will ask questions to astronaut  Matthias Maurer , amateur radio call sign  KI5KF . Local Covid-19 protocols are adhered to as applicable for each ARISS contact. Amateur radio station DLØFHA will operate the contact. The downlink frequency for this contact is 145.800 MHZ and may be heard by listeners that are within the ISS-footprint. The ARISS radio contact is scheduled for Tue 2022-02-22 10:05:11 UTC Tuesday February 22, 2022 at 11.05 CEWT (10.05 UTC). Sc

... URE reports intensive work is underway to make URESAT-1 available before the end of the year. If all goes according to plan, URESAT-1 will launch aboard a SpaceX Falcon-9 rocket from Cape Canaveral in October 2022 A translation of the post by Spain's national amateur radio society URE says: URESAT-1  is based on the architecture used in the GENESIS, EASAT-2 and HADES missions but will include significant improvements, such as a 32-bit computer compared to the 8-bit computers of the previous satellites and improvements in the mechanisms of deployment of antennas and batteries. As for its functionalities, it will have a VHF / UHF FM repeater and FSK frames, like its predecessors. This will allow voice QSOs and digipeating of AX.25 and APRS frames. The payload is not yet defined, but it could be the same SSTV camera that flies in HADES, a thruster or some kind of experiment. Talks with universities and companies and is expected to be closed in the coming weeks. One of the projects

Message to US educators: Amateur Radio on the International Space Station contact opportunity Call for Proposals New Proposal Window is February 21, 2022 to March 31, 2022 The  Amateur Radio on the International Space Station  (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS.  ARISS anticipates that the contact would be held between January 1, 2023 and June 30, 2023. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

... WIA News reports on the tragic conclusion to a missing persons story reported on WIA News several years ago. The bodies of an amateur radio operator and his companion have been positively identified. Russell Hill VK3VZP  and  Carol Clay  disappeared two years ago in the Victorian bushland where the two had gone camping. The last message heard from Russell was on March 20th of 2020 when he made a QSO on one of the HF bands, reporting his location at Wonnangatta Valley in the Victorian Alps. No one heard from them again. One day later, campers discovered the radio operator's vehicle and the couple's campsite destroyed by fire. Forensic testing has now confirmed the identity of remains found last November as those of the radio ham and his friend. A man who had been camping nearby -- was arrested last November and charged with two counts of murder. The man, in his mid-50's is due in court in May. Victorian Police have described the couple's disappearance as one of their

... This is Marty VK4KC, Parks on the air (POTA) admin for Australia to inform you of a new software utility for windows, that Alan McDonand, VK2MET has written called   mParks converter . The WWFF and POTA programs share the same parks in Australia but they do have their own unique park number systems so mParks converter will analyse your log file from a park activation whether it be in the WWFF or POTA format and quickly convert it to the other format, that being POTA to WWFF, or WWFF to POTA. For those using this utility it has saved so much time and effort over manually editing logs. The utility also features a spot builder for when you are out activating with no mobile phone coverage. It will create a message using the correct syntax that you can copy and paste into JS8Call to get that spot through to parks peaks and POTA spotting pages. WWFF and POTA programs were born from one origin but diverged some years ago. They share a lot in common but also offer differences which may hav

... VK6WIA NewsWest NewsWes t for Sunday 20th January 2021 is the History edition of NewsWest. What’s a 'Mulgaphone'? And how do you test night time radio signal fade with two kerosene lanterns? Listen to NewsWest and you’ll find out. A few of our history items today are in support of the VK90ABC special callsign marking the 90th anniversary of the Australian Broadcasting Corporation, so we’re bringing you stories of early Amateurs in Western Australia, and their links to and involvement with the development of broadcast stations in this State. There’s another special event callsign coming up, VK80LAN, which is part of an international activation, and we remind you of that one, and it’s being coordinated by VK6 locals. Mac VK6MM brings us a story of his early transition into transistors, we remind you of the PARG Swapmeet next weekend, Roy regales us with the Amateur Radio Helpline, very likely the oldest continuing segment in Australian Amateur Radio news. Maybe worldwide. Who

A sunspot group emerged on February 10, two more on February 11, two more on February 14 and three more on February 16, when the daily sunspot number rose to 111 — the highest value for this reporting week and well above the weekly average of 75.3. The average for the previous week was 83.9. On February 17 another new sunspot region emerged, but the daily sunspot number declined from 111 to 103. The 111 sunspot number was the highest since the end of 2021, when sunspot numbers went as high as 147 following a few days of no sunspots at all. On Thursday, February 17, the Daily Sun image on  Spaceweather.com  showed seven sunspot groups, the whole earth-facing side of the sun peppered with spots. Average daily solar flux declined from 126 to 110.1. Average daily planetary A index went from 14.4 to 13, and average daily middle latitude A index declined just 1.3 points to 8.3. Why do we care about sunspot numbers? Because high values correlate with greater density in the ionosphere, which g
