[Johnson] Viking II-CDC

I was looking at a 1956 issue of the Radio Annual in it has info on building
a VFO using a Collin's PTO.  The PTO used was the one out of the 75A series
receiver.  I see Fair Radio presently has PTO's from the KWM
series transceivers for $75 Dollars.  It should not be to hard to track
down a PTO for either a R388 (51J) or an R390A receiver, which is more like
the one used in the article.  With people who worship Collins 75A receivers
somebody using a Holey Collins PTO for a homebrew VFO might get you
excommunicated. 8^)

Hi Walt... Viking IIs aren't all that rare-I don't know what the 
"CDC" means. As for a BC-221... they are designed to be VERY 
harmonic-laden-or at least, that's my impression. I wouldn't do it. 
If you insist, use a multi-pole BPF tuned to the band you want to use 
between the '221 and the Viking II.
