If the M.O. output is stable, with and without keying, then it would be just
fine, for CW anyway, one of my transmitters is the RCMA ET-8010A
pair of 211s in the final 807 driver, 807 M.O. and is extremely stable for
that era, remarkably so.

There are those who would say you need the latest digital whiz-bang Gimcrack
but that is not necessarily the case.

One way to find out if 500 KC might be of interest to you is to dust off a 
tune to the freqs. and see what you hear, mind it will be mostly CW, and CW
beacons for now, but this is just the first round.

Signals are being monitored and you can see if/when folks are transmitting
over the internet by going to

or for Buffalo, NY
or for Kellog, Ohio
or for Seneca, Missouri

There are lots of opportunities for development work, (homebrewing)
antenna work, (a 30 to 40 foot vertical works), and testing your skills
against band conditions.
