We're talking about two different things. What OK1RP may be hearing is the ATU switching its relays when he first transmits in a band segment that requires new LC settings. The firmware attempts to do that between CW elements (in RX mode). This should be extremely rare. (If it's happening more frequently, it could be related to particular combination of AGC and QSK menu settings along with high QRM/QRN on a given frequency. I would try selecting "OLD QSK" or "NEW QSK" to see if that has any impact, and/or increase the AGC THR value.)
The PA temperature anomaly reported earlier should also be extremely rare, and in fact no one had even mentioned it in years. Nothing has changed in this firmware recently. But I'm working on a firmware improvement for that and will discuss it later after testing.
