Nothing like the proper gear you guys have, but have been able to do frequency adjustments by viewing signals on an RTL-SDR band scope. Have used a nanoVNA as a signal source before, and have heard of using a sound card as a signal source to produce different wave forms but haven't gotten that far.
The tough one for me to adjust is side band. On a band scope, the carrier space is blank, so there's no visual cue to align? I've relied on signal reports of precisly how high/low I am in hz, and then been able to adjust it accordingly with the aid of the band scope.
