[Johnson] Viking II-CDC

[Walter Treftz]

To all that have offered help and hints, I want to thank you for your input. 
According to the manual,
the CDC will hit all the WARC and pre-WARC bands with an input between 1.8 
(160m) and a little over
6 mcs (10m).  In order to keep the
project within a reasonable budget, my plan now seems to be leaning towards 
using a BC-221
(since I already have one) and a homebrew buffer/driver tuneable between it 
and the CDC.
I know the 221 is pretty rich in harmonics so this plus the tuned stages 
inside the CDC should
take care of unwanted freq radiation --- besides, considering what a desert 
HF has become with
hundreds of kcs between signals, the changes of interfereing with anyone is 
rather remote.
The driver will be rather simple. Just a tapped coil in the tank but won't 
need a meter as can tune
it by the buffer level in the CDC on its meter. Considering all the junk I 
have in the garage along with
the BC-221, this should accomplish the job in less than $10 -- most will be 
labor on my part.
   Will be on the lookout at the ORL fest in case something better comes up.
Again, tks for the ideas and input.
