Any wind? Feedline motion can cause that,
depending on surroundings and if open line

On my last two portable outings I've noticed
that after a few QSOs I start to get unstable
SWR readings, with the radio reporting
fluctuating SWR ranging into the 2 and 3's. I'm
using a tuned antenna, plus pressing the ATU
button results in 1:1 matching. Everything is
fine for a while and then the SWR reading go
unstable midway through the QSO. Pressing the
ATU button seems to resolve the problem for a
while but it starts up again. I realize it
could be a problem with the cabling or antenna
but visual inspection seems to indicate
everything is fine and so far I've not been able
to replicate the problem on the bench. Has
anyone seen this type of problem with the KX3?
