Using TXOffset / RXOffset?

Hi all,

in the frequency tables there is an option to add RX and TX offset. Is there anyone using this possibility?

My idea is to use it for Transverters. I thought it was going to work like this, that in the NewQSO window if yo enter a (uW)band like 5.7GHz the that is would will be saved in the log and shown in the QSO window. But the frequency sent to the rig would be the IF frequency based on the TX / RX offset for that band.

Is there anyone using it? Does someone have some clues how to set it up???

Many Thanks in Advance!

Hi!
Never used it (except when testing) but you will find a brief explanation from Help/Operation/NewQSO(online logging)

Hi,

Hi,

thanks for the hint! That one I have missed. There is however another table for offset which is more appropriate in my case as I automatically want the right display and rig setting when I select the band in question. (This is how WSJT-X handles the offset.) The table I have in mind is found at:

File / Preferences / Bands / Frequencies

In the table there are columns with RX offset / TX offset which I thought was going to be used like in WSJT-X. :(

HI!
That table was the one I have forgotten!
I hope it works there. I assume I tested it when I created the new frequencies table that gives more changes to define mode segments inside the band.

Unfortunately it is not

Unfortunately it is not working as I expected (Like in WSJT-X). To me it seems like that the offset values are not "loaded" and/or being used. But I might have missed something...

Anyhow what confused me from the beginning was that there was two different handlings of the RX / TXOffset. But now when I have realized that there are two of them it is easier to trace down why it is not working for me.

I think I have managed to switch to the new frequency tables.

Hi!
Checked the source and it seems that rxoffset and txoffset in bands/Fequencies table are used when set/get rig frequencies via CAT control.

When reading rx frequency from rig the rxOffset value is added to reading that rig gives.
When setting rig frequency txOffset is subtracted from frequency that is going to be sent to rig.

Offset value (in MHz) may be negative or positive and it is saved to cqrlog_common.bands database table.

Tested values using 20m band and they seem to work.
------------------------------

How ever they have nothing to do with NewQSO/LO Config values.
LO config values are stored in config file under [NewQSO] chapter.

Hi,

Hi,

thanks for checking it up. That is roughly what I also have figured out.

However in the "TRX Control" window there are no buttons for the microwave bands. The only way, I have figured out, is to use the frequency in the "New QSO" window to set the frequency (The band will then be based on the selected frequency). And then it doesn't work.

Basically by using one of the push-button in the "TRX control" window you can get CQRlog to understand which band you are working. But for microwave bands I have not figured out how to do it. The way I understand it we need to add more push-buttons for the microwave bands in the TRX control window. If it gets too cluttered we could use the "Bands" preferences to select which buttons to show in the TRX control window.

Have I missed something?

Cqrlog is more or less designed for HF (and CW) in mind.

There are three user defined buttons in TRXControl window.
I use two of them to get to 60m and 4m bands.
Same design can be used for other bands too.

Preferences/TRXControl:

60m button sets frequency and mode and 15W output power (w command with hex bytes, not all shown in picture)
S/P starts bash script that toggles between straight key and paddles and also rises output power back to full (more w/hex commands in script)
4m button just sets 4m CW keeping other rig settings as they are.
