[Elecraft] KAT500 beta 2.04

[Dave]

Given we are talking about Beta software, I think I have located another 
issue with the KAT500...

If I use any sort of fast turn around transmit/receive cycle software, 
like VARA, under Winlink, or ARQ type software modem, the tuner tries to 
re-tune every time a most transmit cycles, even with a good SWR on the 
antenna.

My antenna has 1.5:1, and if in bypass all works fine.  If in MAN, the 
tuner goes into a tune cycle...  Which faults the KPA500.  Any suggestions?

I do not have a computer connected to the KAT500, but could connect one 
if needed.

73, and thanks,
Dave (NK7Z)
