K2 XIT
Locked
 
|
With XIT selected, should the readout indicate a difference in transmit
frequency when the knob is turned? Readout varies when RIT or RIT/XIT is selected. I recently called 2 stations split using XIT and found I was on their Rx freq. Very embarrassing but doesn't seem to be doing it now yet the readout is as above. K2/100/160/SSB 5545 bought at Dayton, all working well except for this.

Firstly thanks to everyone who answered my query, either on the
Reflector or privately. I can confirm that everything that you all suggest should happen is happening. So from the RIT/XIT point there is no problem with my K2 and I was using it correctly. On rethinking this I wonder if I have another problem. I haven't had chance to do any further checks but since I had (successfully so I thought) re-aligned the K2 earlier in the day, I just wonder if I have the BFO in the wrong place, even though filters all sound good. I used Spectrogram. Scenario 1 - Hear VQ9JC on 20m and want say hello/goodbye before he leaves there. He is working split, so switching RIT on & off, I find his rx freq and tap XIT. He completes a QSO so I call. No QSO. This happens several times including a policeman who says G3 Up. I sense something is wrong and stop calling. Jim has confirmed he heard me on his TX freq at a good strength but didn't want encourage a co-channel QSO. Fair enough but I was convinced I was transmitting split. Scenario 2 - Was a bit apprehensive after Scenario 1 but decided to call NO2R in ARRL 160m contest. I know I can works States on 160. Had 19 Stateside Qs in the last hour of RSGB 160m Contest recently. Nothing, even pushing my amp hard. Most unusual. This was co-channel, no split. Once is one thing but twice makes me feel there is a problem. RIT/XIT looks OK, so I think I need to do zero beat and BFO checks before I go much further.

Chris,
The BFO should take care of itself - BUT if you were using FL2 thru FL4 to receive and the FL1 (transmmit) BFO was set to the sideband opposite from the filter you were using. A quick check of the BFO frequencies for all filters should reveal a sideband swap readily. I am not clear on all parts of your operation detailed - you said "switching RIT on & off" which is the part that is not clear to me - you must turn on RIT and tune (with the RIT knob) to the frequency you intend to transmit on - then activate XIT, and go back to the intended receive frequency by turning RIT off. If that is your procedure it is correct, but I did not understand all the steps in the procedure you outlined. 73, Don W3FPR > -----Original Message----- > > Scenario 1 - Hear VQ9JC on 20m and want say hello/goodbye before he > leaves there.

Thanks Don. I will check tmw, it's getting late here now. Maybe I have
got the wrong sideband, that would certainly explain a lot. Yes, that is what I was doing. Just toggling RIT button to check when he was txing and then to find the station he was working. BTW, thanks. You gave me my own toroid winding demo at Dayton on the Saturday, as you had already done the official one on the Friday. It helped! 73 Chris G3SJJ zzzzz Don Wilhelm wrote: > Chris, > > The BFO should take care of itself - BUT if you were using FL2 thru FL4 to receive and the FL1 (transmmit) BFO was set to the sideband opposite from the filter you were using. > > A quick check of the BFO frequencies for all filters should reveal a sideband swap readily. > > I am not clear on all parts of your operation detailed - you said "switching RIT on & off" which is the part that is not clear to me - you must turn on RIT and tune (with the RIT knob) to the frequency you intend to transmit on - then activate XIT, and go back to the intended receive frequency by turning RIT off.
