Can anyone help me with the wiring mods needed to
use a HeathKit VF-1 VFO with my Viking 2 transmitter?
The VFO came to me wired for a Globe Scout.
I need to know what the wiring is for it to be powered by
the Viking.
Also the VF-1 has a plug for a crystal socket,
can I change it to a PL-259 to
Ron,
Unless someone has done some rewiring, it should be fairly straightforward to
use the VF-1 with the Viking II.
The VF-1 requires 6.3 VAC for filaments and 250-350 VDC @ 15-20 ma for HV.
The Viking II has 6.3 VAC and 300 VDC so the power supply for the VF-1 is no
problem.

Hi Ron,
Yes, you can put a PL-259 on the coax from the VFO.
Pinout for 8 prong octal socket on the Viking II:
1, 2, 4 6: Ground
3: B+ 300VDC
5: NC
7: 6.3VAC Heater
8: Cathode of first oscillator V6. (provides cathode keying)
