Fisher model 4400
#11

Yes, I know...sorry I didn't clarify that. Still, I had set an upper limit of $200 which may, or may not, have been a reasonable limit.

I guess I was just spoiled by my old Clough-Brengle AM-SW signal gen, which does put out enough signal to drive a freq counter. I modified my C-B to add a second output at full power (bypassing the output adjustment controls), terminating in a BNC connector. A cable runs from this to my B+K freq counter, so I always know what frequency the C-B is dialed to when performing alignments on the old Philcos. The BNC connector is in place of the old "external modulation input" jack, so the mod is fully reversible.
