Anyone who has a scrapped Yaesu / Sommerkamp HF rig from
30 years ago, or so, will find that for both TX and RX, the
tunable IF covers the 60m / 5MHz band.

I am thinking specifically of the FTDX560 / Sommerkamp 747 where the
tunable IF is 5.220 - 5.720, and covers down to 5.125 off the lower limits
of the VFO, IF is 3.180, so it is (was) essentially a 60M rig with an
Xtal controlled treansverter.

There is a block diagram of the Yaesu FTDX560 on page 3 of the manual
he
http://www.foxtango.org/ft-library/F...ers_Manual.pdf

The IF is 5.52 to 6.02MHz

I'd be interested to know if anybody has successfully mod'd any of the
1970s Yaesus to cover 60m. I have an FT-200, but I'm guessing that's
unfeasible as the VFO covers 5.0 to 5.5MHz
