Anyone who has a scrapped Yaesu / Sommerkamp HF rig from

The IF is not tunable. It's fixed at 9MHz. It's the VFO that covers
5.0 to 5.5MHz.



My FT560 has a tunable IF of 5.520 to 6.020MHz IF is 3.180MHz
-sidebands would be the wrong way round .

Interesting ... I was referring to the FT-200, and I believe the FT-101E
and its derivatives have a similar mixing arrangements, though with
different combinations of VFO and pre-mix frequencies.

I suspect the FT-200 would be impossible to mod for 60m, as the required
frequencies are in the middle of its VFO coverage. Are there any mods
out there for the other 70s vintage FTs?
