The signal is PSK.

I missed that bit. I thought it would be simple AM.. If the integrated
signal (after feedback diode demod) differ enough in amplitude (or AC
content) with frequency, threshold detection might be enough. I'm just
pondering it though, I have no idea if it can be done with less power than
you can give it.

The signal is also AM, but the PSK is supposed to be detectable at lower
signal levels.
