[Apologies if this appears twice ‹ my first transmission seems to have gone awry.]
When condx are noisy I like to crank the AF gain way up and back the RF gain way down, and use the RF gain for volume control. Doing so isn¹t useful for weak-signal work, and it has one drawback (it makes internal noise more audible, e.g. the TR switching); but it makes CW rag-chewing much more pleasant when the QRN is high. The KX3 uses a push on the AF/RF encoder to toggle between AF gain and RF gain. But here¹s the weird thing that happens with the control set at RF gain, the system sets itself back to AF gain when the internal ATU is cycled. It¹s mildly annoying whenever a QSY is large enough to call for an ATU tune, the radio requires that I manually toggle back to RF gain. That is, it reverts to AF gain simply by having the ATU cycled. I tried other functions to see if anything else causes this perverse refusal to keep my preference intact. The reversion to AF also occurs when XMIT/TUNE is pushed, when Band+ or Band- is pushed (even after returning to the original band), and when Mode is changed (even after it¹s changed back to CW.) It does not happen when the transmitter is keyed (so it¹s probably not stray RF doing this spooky thing), nor when any of the other controls are switched pressed or twisted I wonder if anyone else with a KX3 has seen this happen choose RF gain, cycle the ATU, and see if the system returns the RF/AF control to AF gain. It would be nice to know if mine is unusually cranky or if it¹s in the radio¹s genes. Anyone have an idea why it¹s happening? Or how to keep it from happening?
