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

[Ken Simpson, W8EK]

Hi Gary,

Thanks for all of that good info.

I have tried what you outlined at least a dozen times, and can not get
an offset.  I do not get an offset any place.  Not in memory, non in
entering manually, not at all.

I will get both manuals and see what happens.  Maybe I overlooked
something.  I bought the HT used, so who knows if someone played with it
before me.  Probably fairly likely!

Thanks very much for all the info.

73,
Ken, W8EK
