DX-100B Problems Continued

[Chuck W4MIL]

Hi Fred.............

Interestingly enuf............the DX-100 VFO is a VF-1.  Just in 
different clothing.  I would guess that another external vfo would work 
provided it produces the range of frequencies needed to emulate a VF-1 
or the existing internal one.

If I'm not too far off base, the VF-1 is pretty much the same design as 
the EF Johnson 122.  I've owned a couple of them and I seem to recall 
that the 122 had a quirk whereby it actually used the design of the 
oscillator in the Viking II transmitter as part of it's output scheme.  
At least one one or two bands.  I'm thinking maybe the 160m band.

Something tells me the DX-100 and the VF-1 have a similar relationship.

It's been a long time back and I cannot remember any of the 
particulars.  And my EFJ 122 and Viking II are doing duty at some other 
qth these days.  Fortunately, my DX-100 is playing like a champ with 
the internal (vf-1) lashup.
