[Swan] RIT on a Swan 500

[Maynard Wright]

I've been using a 270B and 350B "as is," accepting the offset that they came 
with and using a guitar tuner to set each rig right on frequency for CW nets.  
I also use an MFJ-752C audio filter for CW selectivity.  With white tape 
markers next to the FREQUENCY knob, I can set the frequency pretty close even 
without the guitar tuner.

An additional VFO would be nice, especially for offsets when working DX.

73,
