[Elecraft] KAT3 settings saved per band
I use two doublet antennas, one hooked to ANT1 through a balun for 40M which uses the KAT3 tuner, and a second (ANT2) in which I bypass the KAT3 and use an external Palstar BT1500A balanced tuner for 30-10M. Currently, when changing bands I have to remember to bypass/set the KAT3 correctly. I would like to see the KAT3 bypass/auto setting saved per band as is commonly done on other rigs, such as the IC756.

RE: [Elecraft] KAT3 settings saved per band
I do something similar with ANT1 and ANT2 with ANT2 having an external tuner out at the antenna feedline base, and ANT1 always being tuned by the internal tuner, and would like some way to associate the ANT1 as AUTO and ANT2 as BYPASS (or vice versa), plus the ability to use it as it now is for those who don't have this sort of antenna set up. Just a thought. 73, Ken, NU4I -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Monday, September 29, 2008 9:01 AM To: elecraft@mailman.qth.net Subject: [Elecraft] KAT3 settings saved per band I use two doublet antennas, one hooked to ANT1 through a balun for 40M which uses the KAT3 tuner, and a second (ANT2) in which I bypass the KAT3 and use an external Palstar BT1500A balanced tuner for 30-10M.

Re: [Elecraft] KAT3 settings saved per band
Steve, The KAT3 does remember the last tuned settings for each band and each antenna. In the case of an external manual tuner, it is easy to set the manual tuner to the approximate correct settings for each band and then use the internal tuner refine the final match. No need to use the bypass setting. An SWR less than 2.0 for a short run of coax will have insignificant loss. Those with remote auto-tuners cannot use that approach, but it works great with manual tuners. Those with remote auto-tuners or a linear, read below for one way to address that situation. Tuning one of the ANTx jacks into a dummy load is one way to make an effective BYPASS, since tuning into a dummy load will set the ATU for a 50 ohm match. Then just use TUNE (hold XMIT) instead of ATU TUNE for tuning of the remote auto-tuner (keeps from modifying the internal tuner settings). The config menu allows you to set the power level for TUNE separately from the fixed low power level used for ATU TUNE. The same technique works for those using an amplifier - do an ATX TUNE into a dummy load, and then do not use ATX TUNE again when that antenna output is selected. The KAT3 operation may not be the same as that in other transceivers, but with the availability of both TUNE and ATX TUNE, it can be even more versatile. 73, Don W3FPR [EMAIL PROTECTED] wrote: I use two doublet antennas, one hooked to ANT1 through a balun for 40M which uses the KAT3 tuner, and a second (ANT2) in which I bypass the KAT3 and use an external Palstar BT1500A balanced tuner for 30-10M.

Re: [Elecraft] KAT3 settings saved per band
Steve: Consider connecting a dummyload to ANT2, and then tuning the K3 ATU on EACH BAND to the dummy load. Then, when you are on the Palstar-tuned antenna, and it is giving 1:1 (supposedly 50 ohms, similar to the dummyload), the ATU will already be matched to the anticipated 50 ohm load and won't require 'tuning', but also won't require BYPassing either. 73, Tom N0SS At 08:00 09/29/2008, you wrote: I use two doublet antennas, one hooked to ANT1 through a balun for 40M which uses the KAT3 tuner, and a second (ANT2) in which I bypass the KAT3 and use an external Palstar BT1500A balanced tuner for 30-10M.
