Thank You Rob!! Ive been fiddling with this for a while and never quite getting the VFO “perfect”. It was close but I was being told my audio was a little tinny. I found my VFO setting put my audio response at 1100 to 4200 hz. I’ve adjusted the VFO and now (with this generator tool) I can see my audio response is 512 to 2600 hz and sounds much better. --
