Re: T-4XC has a "condition"

Agree Gary....I have never set bias by turning "all controls to the left".? Just make sure the GAIN pot at ZERO....CCW.? Seems to have always worked in the past for me.? Good hunch about possible 10m oscillations!? I'm home Sunday and will give that a try if I get a chance.? Will keep Dean posted here on the group site.

I can't experiment with one of my own rigs today or tomorrow, but I'll be able to do that likely on Sunday.? I am now anxious to see if I can duplicate what you are seeing with the RF Tune rotated clockwise into the high end of the 10m band setting.

If there is a difference (there should NOT be), it probably indicates the need for neutralization.? 10meters is where the final can most easily
break into oscillation if not neutralized properly (and with a correctly working transmitter).

I would set the bias on the lower bands, and on SSB with the gain at zero... and after I nulled the carrier!? If the radio is working correctly,
that bias point should hold on all bands, if it doesn't something is wrong.
