	Description:		Dave did a teardown of a plane transponder, so we talk a bit about RF (without much knowledge) There is a PIC16C84 on board Learning or relearning Transmits 1030 MHz, receives 1090 MHz, 140W We’ll ask Jeff Keyzer on the upcoming Keyzermas Crystal radio is basically a pin diode with long antenna. Dodgy wiring on 3.5kW aircon Coefficient of performance Dishy (Starlink) teardown. Discussed briefly when Joris Aerts (518) was on the show. Which PCB software is the best? Question posed by past guest Robert Ferenec. 100 Photos vs 1 Photo anecdote Greg Davill is doing an “Advent for circuit boards“. This had been done by Alan Yates for circuits back in 2014. This is also a thing for learning code, called Advent of Code. These are all based around Christmas traditions (advent calendars) Chris figured he’ll be doing a lot of firmware this winter and asked for advice on Twitter about it. Bunnie wrote an interesting article about the PCB for the Precursor phone (?) Involves past guests Bunnie Xobs and Mithro The Arecibo Telescope has failed and is down for good. The final blow may have been a small earthquake. There are multiple views. Dave and Chris pretty much agree on the Hyperloop Train bridge construction in China. That was not from @MachinePix (by Kane Hsieh) but there are lots of great onese if you follow. Parts Chris is thinking about trying out the CM4. Not mentioned on the show, but Timon did a copper clad PCB breakout for it and it worked great. High speed signal guide from TI High speed getting more common? When Jay Carlson was on the show, he mentioned his intern doing a DDR3 layout easily. Many thanks to our Patrons! You can join at Patreon.com/TheAmpHour if you’d like to join the crowd.
