To protect the rig the Ham must drop the power output to a safe level before initiating a KAT500 Tune operation, just as one would do to adjust a manual tuner. The difference is that the Ham doesn't have to manually turn knobs on the KAT500 to find the best match.
The SWR the rig sees varies widely while the KAT500 is tuning. Some rigs even require manually retuning the transmitter or amplifier output before allowing the KAT500 to tune. The procedure for doing this safely is described on page 13 of the KAT500 manual. 73, Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of bill ny9h Sent: Sunday, December 16, 2012 7:36 AM To: [email protected] Subject: [Elecraft] auto tuners while we are fortunate to have a K3 which auto drops power for tuning,,,, what about rigs that tune at higher power or full power... what does the rig's output see at the input to the tuner when the tuner is clunking/clanking along relays switching C & L components ??? 50 ohms...?? I would think this could challenge the stability of a set of outputs. tnx bill ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
