Interesting Gary, Some seem to get on ok and others have problems. Operator/setup error, perhaps that is all it is? I watched a demo on YouTube of one and quite frankly I would be very disappointed if that was how they operate. I think have seen and read too many conflicting stories now I would have to see one operating correctly and for longer than in a short YouTube video to be convinced either way. Maybe some reports from those who have had difficulty and since sorted it all out would be helpful. 73 John ZL1BYZ

I can QSY, with the kpa500 in OPER and 'IF' the kat500 needs to tune it interrupts the amplifier key line and either selects from memory or does a tune if in auto etc. I rarely see a need for a retune once I have set up. I do this regularly as I am on the move touring and so I change antennas to suit where I am setting up. Wish VK had taller trees in more locations..;-) I have no issues here that need addressing with regards to operation, QSY or band changes/hopping etc.... KAT400 #007 might be licenced to kill but evrything has survived my addled brain and too fast/fat fingers...:-) 73's and Happy Holidays to all.

These could be further apart if you antenna is more broad banded as tuner settings would only need to change when SWR became unacceptable. This would mean with some antenna's and on higher bands probably no chatter at all. 73 John ZL1BYZ. -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of John Shaw Sent: Monday, 24 December 2012 09:46 To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] KAT500 a good tuner or great tuner Very good thought, yes that would happen. A compromise could be some sort of matrix with this mode of operation where you train the tuner at set intervals and the tuner only re tunes when they are passed. This would reduce the chatter and of course the tuner would already be trained so the clicking would be minimal. I could live with that, better than all this hot switching, KPA500 errors and all the on the band QRM that this extra tuning while sending RF. Just a dream maybe but I know Elecraft is a progressive company always looking for ways to improve their product so thought I would pipe up. 73 John ZL1BYZ. -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Keith-K5ENS Sent: Monday, 24 December 2012 09:00 To: elecraft@mailman.qth.net Subject: Re: [Elecraft] KAT500 a good tuner or great tuner I have asked the same question about the KAT500 following the K3 as tuned to be ready for any keying of the K3. I was told the relays in the KAT500 would click as I was tuning. SO? As an option I think that would be fine to know the KAT500 was tuned at all time.
