[ARC5] Update: BC-669 Project for Veteran, Parts Request.

[Mark K3MSB]

I asked W5JO in Oklahoma about 160M AM frequencies.  His  reply

 "Mark,

There isn’t that much AM activity on 160 meters down here.  I have tried
several times to stir the pot without success.

I get on occasionally and talk to Don, KYV but I rarely hear anyone in the
Texas, Oklahoma, Louisiana, Arkansas area and I don’t know why.  There are
several guys who operate SSB but that is it."
