[Boatanchors] Civil Defense Viking II

[Garey Barrell]

Mike -

I've never seen a manual or even a schematic for the CD version.  A 
couple of the Manual sellers advertise a manual, but since I've never 
actually seen a CD version "in the flesh", I never cared enough to pay 
for a manual!  I have the manual for my standard one.  I know the CD 
version has PTT with a two pin mic connector, and is "General 
Coverage".  Seems like it may have had some sort of speech processing in 
it, but not sure.

The Viking II coverage is specified as

1.8 - 2.4 Mc
2.9 - 4.4 Mc.
5.2 - 8.0 Mc.
9.8 - 15.0 Mc.
15.0 - 21.8 Mc.
21.0 - 30.0 Mc.

So there are a couple of holes in the coverage of the standard model.  
It does cover all Amateur frequencies except the SSB only "channels" 
around 5 MHz, so not sure if that matters.  The Roller Inductor and 
Plate Tuning cap are ganged together in the standard version, so that 
may be why it's not total coverage.    May be as simple as 
more/different coil taps on the Buffer and Driver Bandswitch, and the 
Final IS full coverage.
