K3 3.04 Power Output After Tune

I updated the firmware to 3.04 last night. Today, after I tune, I get no or low power out indicated on the RF meter in SSB. Keying down momentarily restores power in SSB.
Are others experiencing this? Jim W6VAR K3 1644 |

I've been running v3.04 during the CQ WPX contest (7 hours of heavy use so far) and have had no problems with it at all. 73, Dave AB7E Augie Hansen wrote: > Jim - W6VAR wrote: > >> I updated the firmware to 3.04 last night.

I assume by "after I tune" you mean pressing the XMIT/TUNE button to
create a CW carrier at some level between 20 Watts and 100 Watts. I've tried various combinations of power and both the actual measured output and the indicated output on the K3 are both fine. No problem here at all. 73 Dave, G4AON K3/100 #80, f/w 3.04 I updated the firmware to 3.04 last night. Today, after I tune, I get no or low power out indicated on the RF meter in SSB.

When operating split on 40 meters it is necessary to tune one of my TX antennas. Following the successful tune operation (1:1 match) an attempt to call results in very low (<2 watts) output power. Neither talking nor whistling causes the power to return to 100 watts. I have to swap VFOs, switch to CW and key the rig to get the power back to the requested value. Then, of course, return to LSB mode, swap VFOs back so that I'm transmitting on the correct frequency. Based on Jim's description I believe he is having the same problem.

Not using SPLIT. Using the 2TONE test signal on SSB yields ~100W, tune the KAT3 and 2TONE test again yields ~65W. Change to CW, tap the key, back to SSB and I get ~100W. All this into a dummy load & on any band. Other observations: If you tune the KAT3 then bypass the KAT3 it still only outputs ~65W. I also tried various settings of TUN PWR (10, 2, & NOR), all acted the same. Works OK on FW2.82, 'fails' on FW3.03 and FW3.04 73, Bill N2BC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Thank you for the observations on SSB Power Control before and after
KAT3 tuning or when in bypass. We'll be looking more closely at this next week. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Low power output (40watts - 60watts) after using the tuner.

I can turn up the power control and it will increase to where it should be,
even though the power control is allready set to 120w. After a turn or two the power goes back to approx. 100w. I can tap tune again and it will drop to approx 30 w peak on ssb. Talk and turn the power adjust up, even though it says 120w brings the power back up. It's then OK until I tap tune again!

I'm trying to setup my K3 to tune my tube amp. I have TUN PWR set to 25
watts. when I long press the tune button the K3 goes into transmit at the selected 25 watts, in CW mode, but the amp doesn't key. If I press the PTT on the mic the amp goes into tx. I must have a menu set wrong? The only connection to the amp (other then the coax!) is the RCA connector key out on the K3. on Tuner is in bypass, ext ALC is OFF. Any ideas?? 73 Jeff kb2m ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I've noticed a similar inconvenience. The problem for me is that Tune will
not activate if PTT is asserted at the rear panel. In my station I don't have the amp hooked up to the Key Out of the radio. I have a foot switch that asserts PTT to the K3, puts the amp in transmit, and switches the T/R relays. Hit the foot switch and Tune won't do anything. I work around it by using CW mode and a straight key. Your problem may be that Tune does not assert Key Out, but I've never checked into that. I'll find out soon because I'm working on a faster T/R switch with electronic amp bias control so that Key Out controls everything. Then I can get rid of the foot switch. 73 & thanks for listening Carl WS7L K3 #486, one year old and still making Dad very happy. > -----Original Message----- > > I'm trying to setup my K3 to tune my tube amp.

Jeff: Check also the keying requirements for your tube amp and ensure that
they are within the switching range of the K3 - i.e. 0 to +200Vdc and less than 5 A. Note that the K3 is not designed to key a negative voltage that some of the old tube amps provided.

Llye,
FWIW, I am experiencing the same issue running QRP with the KAT3, when it is in use, in 3.03 It does not seem to happen when the KAT3 is bypassed. Engaging the main TUNE button (not the KAT tune), seems to put it back to normal. Now if I can figure out why my "two" sounds like "zero" *sigh* 73, Julius

Hi,
I also have this problem that SSB power is low following the use of "TUNE". I don't have the built in tuner. I use the tune ("hold") function to generate 10W CW for my external remote auto-tuner. In the contest I got into the habit of doing a power cycle after tuning (I now see that there are better ways which helps. I have also observed the slow creeping up of power over several transmissions until it eventually recovers fully. I don't have any precision instrumentation to measure peak power. I just observe the average power on my analog SWR meter and I estimate I start out at 2/3 of what is should be after using tune. I join others in hoping for a quick resolution to this.

Yes, I've had the same problem, after I tune , I get low power out indicated....
