This sounds strange to me. Why would the tuner care whether it is in a QSK
environment? I run QSK with my K3, KPA500 and MFJ-998 with no problems.
Almost sounds like there is some hot-switching going on that makes the tuner
declare a SWR fault. The tuner should be outside the QSK loop
It appears that the HF-Auto's method of interrupting amp keying
involves a separate relay, inside the ATU, that only activates when RF
is sensed and the tuner considers itself tuned. This doesn't work
for QSK, which depends on the amp being keyed *before* RF is
generated.
I would assume that QSK
The KAT500 works fine with QSK. It will not cause any problems.
