Further tests show poor 80/60m performance and there is a significant voltage drop compared with the other LPF’s. I set the band to 6m and found 10.47V at the switching diodes and their respective nodes except for 80/60m which measured at .557V No solder shorts were visible and no hot components found. Input RX current is around .100mA @12.0V When 80/60m is active, the voltage goes to 4.73V instead of the expected 33mV as the others measure. L507 appears open line, I will need to replace it but I fail to see if this could be related.?
