Very nice indeed!

I would still also change the TX LPF that is switched into use when
the rig is on 475kHz with the usual 6800pF/15uH components used in
many designs. T94-2 or T106-2 cores should be fine for the coils at
that power level. After that I would also make sure the output
transformer does not run too hot at the intended max. output power
level.

This mod suggestion came just in time, I think we have a contender to
apply it on. Will report how it turned out in case we get a go at it.

MF,

Just found this nice to read article in the web:

German language.
The OM modified an old IC735 to produce 50W RF power on 630m!
He reports about a QSO to DF0WD :-)
