I hate to add one more post to this, but we all need to remember 
how PSK is generated! It is quite often NOT the pure tone it is 
assumed to be.

I'd agree with Peter, but for slightly different reasons. 

We could count on everything from 1842 (LSB) to about 1834 or so 
having problems on occasion from less-than-perfect systems.

If it was generated some other way than feeding audio from a 
soundblaster card into a SSB rig's microphone jack, it wouldn't 
matter much if it was up around 1840. As a matter of fact, I'd love 
to have a steady PSK marker for the bottom end of the phone band.

Since PSK it is generated in a soundblaster and sent via audio 
lines into a SSB transmitter, that frequency is a very poor choice at 
any time of the year!
