[Elecraft] Control board diode

[Don Wilhelm]

Andy,

D1 is necessary to provide AGC and S-meter indication.

I suspect the owner who lifted the end of D1 wanted AGC OFF all the time.
AGC OFF is available as a 2 button hold (PRE/ATT and AGC) from the front 
panel, but it does not survive a power off cycle.

I would think you should reconnect it.
