[Elecraft] Diode testing

Hi Jaques!
The banded end of a diode is cathode.
The other end is anode witch will give you your readings.
You must look at the other end (anode) witch have no band and meassure =
there.
These ends will have 0 or 8 volts depending on rx or tx.
D6 connects to the 8R (recieve) line and D7 to 8T line.
It's important that this diodes as the others is mounted in the right =
direction.
Check that if you have trouble.

:

> So, I have a look at the schematic, and I see both anodes have a =
common connection to the BPF, so it's evident they should have he same =
voltage !
