[AMRadio] Viking II Audio Mod Question

[Jay Bromley]

HI Scott,
I been on 10m AM a ton lately and on 20m with HiFi SSB.  I put up a 75m
antenna, but it didn't play so I just took it down.  I have in the works a
simple 75m inverted vee.

On the Viking CD, just the audio section.  My rig or what is left of it is a
Viking CD minus the case, roller inductor, etc.  I am thinking to use it to
run some audio experiments, but need a schematic first and wanted to know if
there is a difference between the Viking CD and the regular Viking II audio.
I think I can find a schematic locally if they are the same.

It is a real shame how some of these rigs ended up!!

73 de jay..
