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

[Richard E. <DO...@ho...>]

Hello.


I'm probably too dumb to understand, but how exactly does the G command 
or vfo_op work? For example, I enter G VFOA UP and then check the 
frequency with f, but it hasn't changed. Please explain it to me.


Thanks


Richard
