Re: [Elecraft] [K3] KAT3 not functioning on 6m
This thread saved me. I thought my k3 antenna tuner had malfunctioned on 6 m, but luckily it was only because it was in Split (Data mode). The erratic behavior of the ATU and the SWR are quite confusing though as they tell you nothing about this cause. - Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog: http://la3za.blogspot.com, LA3ZA Unofficial Guide to K2 modifications: http://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html -- Sent from: http://elecraft.365791.n2.nabble.com/ __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] [K3] KAT3 not functioning on 6m
Tune before you run wsjt. The ATU I think forces the VFO into CW mode. Split in a DATA Mode is not allowed if one VFO is not in same DATA Mode. Sent from my iPhone ...nr4c. bill --- It makes me think it is a firmware glitch because this only happens on 6 meters. If I create the exact same circumstances on 160m through 10m, it doesn't happen. WSJT-X Split mode and Tune work fine everywhere except 6m. -- Thank you!

[Elecraft] [K3] KAT3 not functioning on 6m
Bill, It looks like you have uncovered the same apparent firmware glitch I did. I have verified a few friends have the same issue. It is very repeatable on K3 and K3S's. I was using split mode for WSJT-X and when I would press Tune while in Data Mode A to tune my KPA-1500, I get zero power output. If I take the rig out of Split mode, it works just fine. Put it back Split mode, still works fine. Turn the rig off and on again, zero power out again. My solution was also to run WSJT-X in Fake It mode, but I really would prefer to be able to use Split mode. Maybe one day one of the firmware updates will correct that. -- Thank you!

Re: [Elecraft] [K3] KAT3 not functioning on 6m
No, that’s not it. The right is ALREADY in split mode when i attempt to use the auto-tune. You get the N/A flash if VFO A and B aren’t set to the same mode, other than SSB/CW. WSJT-X sets it up correctly, with both VFOs in DATA mode. > On Sep 7, 2020, at 9:50 AM, w4sc wrote: > > Bill, > > The K3 only allows the “split” mode for SSB and/or CW to be enabled, at > least from panel.

Re: [Elecraft] [K3] KAT3 not functioning on 6m
The K3 allows split in data modes, but only provided both VFOs are already in data mode. The K3 will not allow cross-mode split between Data and CW/SSB. If you are seeing "SPL N/A" when you try to enable split with VFO A in a Data mode, what that tells me is that VFO B is in CW or SSB, not in Data mode. When VFO B is not already in the same mode as VFO A, tap A>B twice to transfer the VFO A mode into VFO B before pressing Split. 73, Rich VE3KI W4SC said: The K3 only allows the "split" mode for SSB and/or CW to be enabled, at least from \ panel.

Re: [Elecraft] [K3] KAT3 not functioning on 6m
This is a feature of WSJT-X. If you have the Split Operation selection set to “Rig”, WSJT-X will always use Split mode. It sets the transmit frequency higher or lower in 500 Hz increments. The main reason for this is to keep the generated audio in the middle of the SSB passband, but high enough to allow harmonics to be outside the passband. So, for example, if you select 400 Hz as your transmit frequency, WSJT-X will set the TX frequency 1.5 kHz lower, and then generate transmission tones around 1900 Hz. If you set the frequency to 2000 Hz, it will set the TX frequency 500 Hz higher, but the tone generated is about 1500 Hz. The net result is the same — the transmitted tones are always between 1500-1999 Hz. And even if you select a transmit frequency between 1500-1999 Hz, WSJT-X will always use split operation.

Re: [Elecraft] [K3] KAT3 not functioning on 6m
Bill, Why are you running split in WSJT? The only time you actually need split is when operating 2 different frequencies like working JA's on 160 when they used to be required to transmit on 1908 KHz and we transmitted on 1840 kHZ (they now can operate on 1840). Unless you are actually needing to receive on one frequency and transmit on another, set the radio configuration to "Fake It" instead of "split". That will keep your transmit frequency in the middle of your transmit bandpass. There is no actual frequency change in WSJT including DX expedition mode.

Re: [Elecraft] [K3] KAT3 not functioning on 6m
Bill Upgrading to KSYN3A, you should run the High Power TXGAIN Calibration according to the installation instructions. Actually, I had to run the WATTMETER, and BOTH the LP (5W) and HP (50W) calibrations to “cure” the same issue you are observing. Installing the KSYN3A in a K3 results in lower output on 6M when the KPA3 is active, i.e. the requested power is greater than 12W. When the power requested is less than 12W, the KPA3 is inactive (bypassed), the output power is within measuremt accuracy on an external wattmeter to what is requested by the K3 power setting control. When the power requested is greater than 12 W, i.e. 100W for example, what I have observed is at 52.000MHz the external wattmeter reads 85W, and at 50.500MHz only 63W is realized. There is little difference in the output power measured in each case with/without KAT3 tuner “bypassed” or “enabled and matched” at the operating frequency’s outlined above. It appears that this anomaly occurs only on 6M, I don’t know if there is a solution or fix for the above. K3 F/W 5.67 Load 100W 30Db attenuator Wattmeter HP736 with 8481 power sensor and Bird with appropriate elements.

[Elecraft] [K3] KAT3 not functioning on 6m
I upgraded my K3 to include the new KSYN3A back in November. (I have the KRX3, so I installed two of them) Ever since then, it seems like the Antenna Tuner isn’t doing it’s thing on 6m. It works fine on the other bands. The K3 doesn’t really show any other problems. Here’s the symptoms: - ATU not in bypass - ANT1 or ANT2 - doesn’t matter. - Press ATU Tune - Unit makes noises like it is working on a match, but the entire time, the display only shows “- -“ in the right hand side of the display — at no time does it show an SWR. - Eventually, unit gives up trying to find a match What’s odd is this: - Press Tune, unit outputs power, but no SWR is displayed in the right hand side of the display, only “- -“. - However, if I transmit, I do see an SWR indication in the meter face, and the SWR seems accurate, depending on the antenna I choose. I’m running firmware revision 5.67/2.88 — which is the latest, I believe. Any ideas?
