ANAN 10 Thermal Protection

Postby ww1ssradio » Sat Jan 14, 2023 12:44 pm

Is there thermal protection in the ANAN 10. Was runing a little FT-8 to set it up and after 5 minutes or so it shut down with a fading power light.

Yes. The Hermes board incorporates several polyfuse devices ("PTC"). These are self-resetting thermal fuses. They are denoted as "Fx" where x is the instance on the board. See the schematic: viewtopic.php?f=35&t=2335

There is no thermal protection on the 10W PA board that I'm aware of. See that same link for the PA board schematic.
