[Elecraft] KAT3 tuning bandwidth
Hi, On 80 meters I did some tuning and when I try the SWR about 12 KHz lower the tuner produces an extra click and the SWR is terrible again. It seems the tuner remembers segments of about 20 KHz. Is it possible to keep the tuner in its tuned settings so it is not necessary to tune the complete band in 10 or 20 KHz steps? 73 's Steef PA2A, K3 # 4654 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KAT3 tuning bandwidth
If the feedline antenna combination is such that a 1.5:1 segment is only 20 kHz wide (a common enough occurrence) then one should take the time to get tunings up and down. You can probably do it in a couple of minutes. The K3 will shift seamlessly with your operating after that. One of the benefits. 73, Guy.

Re: [Elecraft] KAT3 tuning bandwidth
Guy, I did another experiment: I tuned on 14.250, 1:1.2 is the result. On 14.240 the same tuning values are used and the SWR is still 1:1.2 From 14.239.999 downwards the SWR is 1:8.3 with other KAT3 parameters. Up to 14.299.999 the SWR remains 1:1.3 and from 14.300 it is 1:6.7. It seems that old KAT3 parameters on other antenna 's are remembered forever. After using the K3 at the IOTA last week there has been much tuning and now all bands should be retuned. I don 't like this at all. A new feature would then be to reset the old KAT3 settings or to 'calibrate' the whole band automatically with the KAT3. And after that it is a little step to a complete antenna analyzer feature on the K3 hi! 73 's Steef PA2A - Original Message - From: Guy Olinger K2AV To: Steef PA2A Cc: Elecraft@mailman.qth.net Sent: Sunday, August 01, 2010 9:35 PM Subject: Re: [Elecraft] KAT3 tuning bandwidth If the feedline antenna combination is such that a 1.5:1 segment is only 20 kHz wide (a common enough occurrence) then one should take the time to get tunings up and down.

Re: [Elecraft] KAT3 tuning bandwidth
Perhaps that is something that could be done with the K3 utility?

Re: [Elecraft] KAT3 tuning bandwidth
Guy, That works! I thought the tuner remained in the same position because no relay clicks were audible when turning the VFO across the band. 73 's Steef PA2A - Original Message - From: Guy Olinger K2AV To: Steef PA2A Sent: Sunday, August 01, 2010 11:35 PM Subject: Re: [Elecraft] KAT3 tuning bandwidth See page 56 in the user manual. Put the K3 on the band you want to clear. Go to CONFIG:KAT3:LC SET. Tap CLR. This should clear the memories for that band. 73, Guy. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] KAT3 tuning bandwidth
There are several solutions here... 1) Clear the memories for the band. Enter Config then go to KAT3 and press CLR. This will clear your current ATU memories for that band and 1 tuning will be used across the band but they will continue to be learned as you tune. 2) Download K3EZ. This is a simple application which one can find by doing a search. This application has a pane that will allow a user to calibrate the K3 to their antenna on a per band/antenna basis. 3) Manually tune in every ATU window. The ATU does stay put as you tune the VFO. Its settings are only updated when you've crossed memory region boundaries and you transmit. As soon as you transmit if you hear a click and the ATU icon flashes that means that the K3 has recalled a tuning memory for you. ~Brett (N7MG) On Sun, Aug 1, 2010 at 3:02 PM, Steef PA2A p...@xs4all.nl wrote: Guy, That works!
