Indeed, Andy is correct. The Elecraft serial is STEREO and the Icom is MONO. I reversed them in my mind and didn’t verify which was which before posting. The main point behind this was to highlight that the two were not interchangeable. tnx Mike / K5JR Alpharetta GA On Mar 12, 2024, at 12:

Re: [Elecraft] KAT500 Attenuator

Guys, I'm not about to remove all of the cables to look but using my iPhone camera it looks like I have S/N 1418, which I kit-built. My R7 is AWOL and R6 measures about 228 Ohm. Looks like Elecraft needs to explain. Wes  N7WS On 12/10/2021 8:25 AM, Andy Durbin wrote: Hi Lyn, Thanks for yo

Re: [Elecraft] KAT500 Attenuator

Hi Lyn, Thanks for your report. Your KAT500 is a later serial than mine so I doubt R7 is fitted. (Mine was a kit build and I don't know if factory units are in the same serial number series) I don't know the source of my Rev C schematics. I received some of my KAT500/KPA500 from Elecraft sup

[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 shown

Hi Andy, No, not with the beta, that is untested at this point. I need to move the new software into the KAT then test again... Thank you for asking! 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst. Director, NW Division, Techn

"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 tri

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
