I am using the most current firmware versions in the K3, KAT500, and KPA500. I am also using the Elecraft auxilliary cables. Not sure what else to check as to why the KAT500 won't update the tuner preselects when QSY'ing? Mike AC6JA In a message dated 6/14/2014 12:37:09 P.M. Pacific Daylight Time, [email protected] writes:
Mike, Not normal! The KAT should QSY if the KAT500 is interfaced with the K3 & KPA500 as per the manual. It is trule a K=Line system! First - make sure you have the most current version of firmware. There have been a few updates that fixed issues that you describe. I have Beta 1.63 in my KAT500. You need the K3, KAT, & KPA all tied together as per the KAT manual. I may not have the same manual as you do but it is the section interfacing K3 & KPA with DB15 cables. Make sure that the antenna selection for each band is correct using the KAT500 Utility. Set the tune power in the K3 - I use 20 watts; because I had an early KAT and that was what it needed. Not sure if it affects the KAT but I have my K3 power set to per band for the KPA. Then you need to train (tune) the KAT on the band segments that you will be QSYing to. The bands have different segment sizes so check the manual. I tune with the KAT in Auto mode. Press the KAT Tune button then hold the K3 Tune button. This should initiate the tune function in the KAT500. I "Trained" my KAT on all bands that I use. I incremented the frequency from the bottom of the voice frequencies to the top frequencies. This did take a while but now I can QSY and a second or so after I stop turning the VFO dial I hear the relays in the KAT set. This means that the tuner is optimized when I transmit. BTW - I do run my tuner in MAN (manual) mode so it does not try to retune on voice modulation. Above is how I operate my KAT. I have an early Kit that has had several firmware updates. A couple were for the issue you seem to have. Mine works well for me with several antennas. Hope this might help you. If not others may have an idea of Elecraft will surly help on Monday. 73 George AI4VZ -----Original Message----- From: Mike Hagele AC6JA via Elecraft Sent: Saturday, June 14, 2014 3:11 PM To: [email protected] Subject: [Elecraft] KAT500 operation? I am using a K3 and KPA500 with the KAT500. I also have the KAT500 mode set to MAN. I thought that the firmware was supposed to switch the tuner automatically when you switch bands? After I go to a new band, I need to tap my key momentarily to get the tuner to tune to the new frequency. Is this normal? Let me know as I thought the tuner would remember the presets when QSY'ing to a new frequency? Any help would be appreciated. Thanks.
