And started measuring the voltage on the diodes in different bands.
When I'm on 20M, D1/D2/D4/D5 are "high" (8.06V to ground when the board is running at 9V)
However, D3/D6 are at 4.7V when, according to the above post, it should be close to zero.
?
Measuring the X6 test point, only "2" is at 3.3V (the other two are at 1.8mV).
?
What should the voltage at D3/D6 be at this point?
