Fern,
Also I doubt seriously the battery on the ram unit is causing this.
Maybe some cracked solder joints where the ram unit attaches to the
logic board. measure the ram battery, it should be something over 3 VDC
if so its fine. The ram draws something in the micro-amps, that battery
will likely out last most of us. I have seen things wehre the IC-745,
751 would transmit fine in VFO but not on some memory channels and it
was the 8 volt supply as I mentioned in another email.
Not saying its absolutely the problem but surely worth a check and if
the resistor is discolored change it out.
Since it works fine on LSB in memory mode I'd suspect the generation
circuits like the LSB BFO are functioning correctly and T-8 volts is
working.
