SWAN 410 VFO...

[W5BIB]

I know that the SWAN 410-C works with my 500c, 500cx and 350c. Will a plain '410' (no letter) work with these same xcvrs? Thanks & 73. Steve W5BIB

I think the plain 410 was to match the Swan 400 transceiver, whose design was the daddy to the 350 and 500 series.
All that matters is that the bandswitched VFO (Swan did this instead of xtal control of the first osc.) has the same output as the internal one. You might have to tweak things a bit, but it should work.
