Hi John,

We have tried the PSK 31 mode A/U before without much success.

If you have the AO-51 book, there is a screenshot of PSK-31 in operation on 
page 34.  The major problem is that the 10M uplink has to be received with 
the 2M whip antenna, not a great match.   The signal strengths were low and 
it didn't prove to be very popular.
