K3: How to determine TX Frequency Over Serial Port

[Paul Fletcher]

Hi all and a Happy New Year,

I need to determine the K3 TX frequency over the serial port and I think I know how to do it but thought I would check to see if there is a better solution.

The steps I think I need to take are:

Determine the TX VFO using the FT; command
Depending on the response (FT0; or FT1;) get the VFO A (FA;) or VFO B (FB;) frequency

I may also need to take account of the XIT offset in a similar manner.

I can't see any other way to do this without reading a lot of info I'm not interested in but open to suggestions. I've searched for a command that gives me the TX frequency directly but can't find one.

Regards,

Look at the IF command - saves a few steps.

The IF command only gives the RX frequency. It will tell you if you are working split or have XIT on as well, so I suppose it saves a few commands, but as it sends a lot of other info you don't need it's arguable what you are saving. You could send FT;FA;FB; as one string and then sort the results out afterwards.

Thanks for the responses - I also got one from Bill that I am posting that gives me one complete answer to addressing split and XIT

From Bill K1GQ:

Here is my algorithm (in C):

transmitFrequency = (splitIsOn ? vfoB : vfoA) + (xitIsOn ? offset : 0);

vfoA is the response to the FA command.
vfoB is the response to the FB command.
offset, xitIsOn, and splitIsOn are found in the response to the IF  
command.
