You don't need to query the frequency from the radio before setting the frequency on the radio.

Subject: [Hamlib-developer] Question on Frequency Adjustment with Rigctl

Hi all,

I have a general question about frequency adjustment. Thankfully, with the small 'f' command we can query the current frequency, and with the capital 'F' we can set a new one.

I'm currently writing a script that changes the frequency in predefined steps—either increasing or decreasing it in a loop. My question is:

Do I really have to query the current frequency from the rig during each loop iteration, add or subtract my step size, and then set the new value again? Or is there a more elegant or efficient way to do this?

I think I read somewhere that it's possible to increment the frequency relative to the current setting. If that's true, how would I go about doing that?

Any tips or pointers would be much appreciated!

Best regards,
