K3 bad TX
Locked
 
|
Hi!
I was trying K3 for first time in SAC contest a couple of weeks ago. During the contest I got multiple reports that besides of my run frequency, I also had other reasonable strong signals "around the band". It cleared out that I had at least one other signal about 7kHz away from my actual freq. It was quite strong, maybe 40dBs down from my running freq. Have anyone else had similar problems and do you have any suggestion how to fix this? I was using only about 60 to 70 watts drive for the amp and amp was not pushed over. The same appears on both, CW and SSB. Radio has the most resent FWs available via K3 utility SW. I'm planning to take K3 with me to CU2 for CQWW, but after getting such a bad reports about "my 2nd pileup" on the same band, I'm not sure if I'm willing to make such an interference to others on CQWW... So if anyone has any advice, I'm more than pleased to hear! 73 de Toni, OH2UA ______________________________________________________________ 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 |

Tke the amp out of the equation and see if you still have the issue. Try a different antenna and check the SWR. I would suspect one of those to be the issue. At least it will eliminate some variables.

Toni,
Do I understand correctly that the transmitter spur is always about 7 kHz away from your actual frequency, regardless of what your actual frequency might be? Or does the spacing change when you change the actual frequency by say 10 kHz? 73, Geoff GM4ESD Toni Lindén wrote: > Hi! > > I was trying K3 for first time in SAC contest a couple of weeks ago. > > During the contest I got multiple reports that besides of my run > frequency, I also had other reasonable strong signals "around the > band". > > It cleared out that I had at least one other signal about 7kHz away > from my actual freq.

G'day,
Just checked here. At 14020kHz and 14120kHz the spur remained approx 6.33kHz away.
