RU Sure ???
The RA1792 (the following model from the 1772 perhaps) displays the actual
frequency at the middle of the filter passband, then generates an audio
frequency output as defined by the BFO setting, up to +/- 8kHz adjustable in
10Hz steps.
It is on SSB where you need to tune 1kHz lower, and then the RA1792 allows you
to use teh narrow filters and has passband tuning where what was the BFO
readout now becomes an offset in the audio band.

Dear Valerio, LF Group,
At 20:08 30/06/2003 +0200, you wrote:
i also tried to listen to SAQ on Sunday morning around 8:30 UTC, but with my
great surprise i heard a strong RTTY station at 17.2 kHz.
I use a RACAL 1772 receiver
Perhaps a silly suggestion, but a mistake I have made more than once...:-)
The RA1772 in CW mode displays a frequency 1kHz lower than the actual
receive frequency - so to receive SAQ you have to tune the RA1772 to
16.2kHz. If the display reads 17.2k, you will be receiving the data sigs
around 18.3kHz.
