[ICOM] Icom IC-02 AT, 2 m HT FS

[Ken Simpson, W8EK]

Thanks, Van.  That is exactly one of the things I have been doing.
Actually, I think I have tried every combination there is.

At this point, I am fairly certain that it has been "modded" with a
wrong diode placement, telling the microprocessor not to talk to the
offset control.

Thanks for your help.

73,

Ken, W8EK
