Royce,
I have found a few hi-band circulators on ebay. Most there are for
microwave but once in a while the lower frequencies ones show up.
I've also found some at hamfests. Picked up one at Dayton this year for
440.
Some are fairly broad banded and some are very narrow. Some have tuning
adjustments and some are fixed tuned.
All are harmonic generators and must be followed by some kind of
low-pass filter.
Don't think I ever paid more than $30 for one.
Have patience. There are some out there.
