[hpsdr] Broken Penelope

[Darrell Basinger]

I have a pair of Penelope's (1 x TAPR & 1 x Gerd / DJ8AY). Initially both worked fine (.5W output). However, both have recently failed (first one then the second) with an output of only 50 mW. Only 3 of 5 leds are on.

 

I have two sets of Alex, LPU, Mercury and OZY. The same low output with both sets.

 

Following the troubleshooting guide on the Penelope Wiki, I measured 300 mV at pin 2 of JP3. If I remover the jumper I measure 600 mV. The VFWD voltage (pin 7 of UB9) measures 1.25 V dc. Is this dc level too high resulting in the FPGA code to reduce the output? 

 

I would truly appreciate any suggestions.
