I'd really like a copy of the user manual, but if that does not materialise,
anyone know the operation of the FR50B?

This is what I THINK it is:

It's a double conversion reciever thus:


\|/RFin RF AMP---- 1st MIX ---- 5173.9 Khz FILTER --
|
L.Osc (VFO)


---------------------- 2nd -----455 Khz FILTER
MIX
|
HETERODYNE OSC (5628.9 Khz)


1st IF = 5173.9 Khz
2nd IF = 455 Khz

It's the frequencies that I'm after for each band. To work them out I need
the mixing details.

I think the mixing details a

80 and 40m: 1st IF = L.O - RF in
2nd IF = HET OSC - 1st IF

20.40.12.10m: 1st IF = RF in - L.O.
2nd IF = HET OSC - 1st IF

Can anyone please confirm this? TIA.
