Anyone who has a scrapped Yaesu / Sommerkamp HF rig from
30 years ago, or so, will find that for both TX and RX, the

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 .
