Tom & Sam-

That is what I was going to suggest. It is a common practice to send a
partially reduced carrier that doesn't eat up a lot of power, but allows
you to synchronize to it using a synchronous detector.

When detected, the carrier translates to zero frequency relative to the
modulation, so it can be eliminated by a DC-blocking capacitor.

I think such a system is in use by some foreign broadcasters. (I'm
thinking one is at 21.455 MHz?) It doesn't sound quite right using an AM
detector. It can be received on an SSB receiver, but you have to
carefully tune it so music sounds right.

If you insist on the 1 KHz pilot tone approach, you could end up with both
the pilot tone and a small vestige of the suppressed carrier. Your filter
system might lock-up on either the pilot tone or the carrier!
