the lock function of fldigi only works for TX, so your beacons will be spot on 

The RX is hunting for a valid psk signal within a narrow band which can be 
Goto configuration->modems->psk and set search range to 40 Hz, and acquisition 
level to 6dB.

That should do the trick. Do you use fldigi 3.10?
