Re: [Elecraft] K2 XIT/RIT
David, thanks. I think I have sorted it all, at least on CW! I have just re-aligned with the Spectrograph. The MP has on offset in the display I recall, so displayed is actual frequency, (I think!) Now, simulating a QSO, ie transmitting on K2 and tuning in on MP, then txing on MP and listening on K2, I hear each signal without retuning, and as it happens both indicate the same freq. I am now convinced that I was transmitting 1 KHz lower before, which explains why I was calling VQ9JC on his tx freq even though I had XIT in, and wasn't being heard by NO2R who was listening co-channel. Apologies to everyone for the numerous emails, thanks for all the advice. A learning curve!

Re: [Elecraft] K2 XIT
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 z 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.

Re: [Elecraft] K2 XIT
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.

[Elecraft] K2 XIT
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.

RE: [Elecraft] K2 XIT
Chris, hen the K2 is in receive, the receive frequency only is displayed. In transmit, the transmit frequency is displayed (hard to see during keying). Check the K2 manual page 94 for information on how RIT and XIT work - when XIT is on, you can see the transmit frequency during receive by also turning on RIT. I prefer to jusst use split all the time - it better matches my thinking - I find I can get confused with all the combinations, especially when trying to operate quickly. 73, Don W3FPR > -Original Message- > > With XIT selected, should the readout indicate a difference in transmit > frequency when the knob is turned?

[Elecraft] K2 XIT
It will show the offset when you actually transmit. You should engage both the RIT and XIT and then when you wiggle the offset knob, you can "see" the qrg change. Then release the RIT and you're back on the correct listening qrg and ready to xmit on the qrg with the desired offset. It is a pain. See my previous posting (link below). de Doug KR2Q http://www.ac6rm.net/mailarchive/html/elecraft-list/2006-11/msg00882.html ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 XIT
Chris, What you are seeing is correct. Only when you go onto transmit will you see the effect of the XIT on the frequency readout. If you want to know exactly what frequency you will be transmitting on with XIT selected then you can select the RIT as well. Of course you need to deselect the RIT to listen on your original frequency. Hope this helps.. 73 Stewart G3RXQ On Mon, 04 Dec 2006 13:40:53 +, G3SJJ wrote: > With XIT selected, should the readout indicate a difference in transmit > > frequency when the knob is turned?
