[Elecraft] KAT500 Attenuator

KAT500 has an input attenuator that may, under certain conditions, be activated during a full search tune. Page 1 rev C of the KAT500 schematic shows the attenuator is a divider consisting of R6 and R7 which are both 39 ohm. My KAT500 serial number 2609 does not have R7 fitted and R7 is

"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." Are you saying that you see this with beta 2.04? If so, have you

Re: [Elecraft] KAT500 beta 2.04

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
