I followed the procedure Markus suggested with no change to my K3 RF gain tracking between main and sub Rx.
I have been listening through the 2.7 KHz stock filter in both receivers with identical PRE and ATT and both filter gains set to 0 and identical IF filter bandwidth settings and both receivers sharing the main antenna. I have SQ MAIN = 0; SQ SUB = 0, SUB AF = nor. The offsets are matched on both filters and set properly. Still full CCW on the sub is about 12:00 O'clock on the main. At full RF gain both are about equal. Strong signals are still copyable on the sub Rx with full off RF gain, the main is dead when RF gain is minimum. So I tried an experiment, set main IF Filter (stock filter) to a maximum of +8 dB gain leaving the sub at 0. I still have more gain on the sub Rx than the main at low RF gain settings. At high gain settings, now the main is louder than the sub. So back to zero on the filter gain and very different gain tracking between the receivers. Audio gain perfectly tracks by the way. My K3 behavior is as if Wayne were reading every other RF-Sub gain control impulse and every one on Main. I received a few direct emails from other K3 users and theirs act just like mine. Markus' K3 is now the only one I have heard of that is acting like expectations.
