I have had my U3S running (nearly) non-stop for a couple of years with no issues.? WSPR spots reported from Japan to Germany.
Recently...nothing.
The QRP-Labs Dummy Load reports:
? 80 meters: 0.022 volts (yes, that's two one-hundredths of a volt)
? 40m: 0.03
? 30m: 0.09
? 20m: 0.05
? 10m: 0.04
I will appreciate hearing from others who might have experienced something similar.? Where did you start troubleshooting? Were you successful in returning your U3S to operation?? What was the fault?
I was running at 5 volts, with a single BS170, 5x switched filter board, GPS mounted in the top of the standard enclosure (patch antenna fed through).
Thanks.
