I've checked that manual twice (the version I had downloaded some time
ago and the one on the web site) and there are only two diodes on the
control board.  Are you confusing the terminal locations: 11, 12, 13,
14 and 15 with diodes?

I have problems with the meter on my ham 4. The schematic in the manual
and on the Hy-Gain website leaves a little to be desired. My meter
circuit pc board has 5 total diodes on it. CR1 and VR1 are defined as to
what they are. The 3 diodes on the top of the board are not shown on the
schematic or say anywhere what they are. I believe they are IN4008's.
Can anyone verify if I am right or not. I wrote to Hy-Gain and got a
hand drawing added on the original schematic but it only added 2 diodes
and never labeled what they were. They need to update their schematic.
Any help is appreciated.
Thanks.
