[Johnson] RANGER II VFO LEAKING

[Rodger]

Harold,

I assume the heterodyne is tunable with the VFO.  If this is the case 
then check the adjustment of R-39 (VFO keying).  You could also have a 
defective keyer tube (V-14) or a problem with the bias supply but it is 
probably just an adjustment.

Checking the archives and some notes that I have been keeping, I note that a similiar problem was reported back in 2000 by one WB6ORZ. This writer said it sounded like an RTTY Signal. The problem was found to be C15 in the tuned tank circuit of the VFO.
