    Gaston Raspberry Pi 3B+ CPU cooling: case evaluation and software/hardware optimization What: Looking for perfect RPi 3B+ field case for a software project Why: Sonoran Desert & field operations How: Added CPU temperature telemetry (app + cron job) + journal/graphs Baseline: CanaKit Raspberry Pi 3 B+ (B Plus) with Premium Clear Case and 2.5A Power Supply iUniker Raspberry Pi 3 B+ Case, Raspberry Pi Fan ABS Case with Cooling Fan Unistorm Raspberry Pi 3 Model B+ Aluminum Case with Dual Cooling Fan Metal Shell Black Enclosure Flirc Raspberry Pi 3B Case (not yet tested) Pi 4 testing TBD with Argon ONE V2 Raspberry Pi 4 Case with Cooling Fan  Cases: Findings: active vs passive cooling Mark Looking at M17 again. They’ve come a LONG way since I started the protocol spec doc a year or so ago.  Provided a couple minor updates in a pull-request, mostly around Crypto protocols.  I have a couple MD380s that I intend to use for M17 hacking. Haven’t done anything yet though. Another Field Day, another single episode working on my Contest Station Audio Interface Thingamajig. Debating between two designs: Single unified device, one board with all cables going in and out, all mixer controls in a single place. Distributed devices, with an RJ-45 bus connecting them. Puts controls nearer to the operators/radios, but is more complex.  Allows for further expansion. Playing a bit with my shiny new toy: Flex6400. Book recommendation: The Cuckoo’s Egg, Cliff Stoll, K7TA. Not ham radio related, but I suspect will be of interest to hams.

Dr Zip ,

I’ve found my happy place!

Finished watching the Ham Radio Workbench presentation on the QSO virtual hamfest last night. The humor was outstanding, The Canadian contingent was excellent. I didn’t know Canadian Ham’s had such a great sense of humor. The tech information was great as always, but the star of the show was the prototyping of the pin or patch to detect at first fellow watchers of ham radio workbench then with further design work it could be engineered to be a COVID detector!
George, you and your cast of fellow nerds are simply “The Best”
Thank you!!!

Episode 130

Just now taking the podcast #130 directional antennas. However; A-the full wave loop, or quad loop reduces noise as compared to yagi because the vertical portions on the square loop cancel some of the natural and man made noise. Also, the quad loop is usually a DC ground aerial and that furthers noise reduction. B- its not a yagi without a reflector or a director. A rotary dipole is not a gain array, it is only a bi-dictional gain less Dipole.
Otherwise good program and lots of correct data.
PS: wire beams on 75 and 40 meters where the trees are available.
