[Icom] IC7800 replaces IC781???

Tue, 22 Apr 2003 13:14:21 -0700

Hello Jim,

Others have asked, and I'll reiterate.  Have you checked the traces =
around
the parts you touched to make work?  I would check all traces (with an =
ohm
meter while flexing tie board) to/from those parts as well as those in =
the
physical vacinity.

If all else fails, don't butcher it for a parts rig.  You still have an
awesome HF receiver!
