Gabriel,

Look at the Mode tab at the top of the program.

<I'm playing around with SATPC32 and its CAT interface to 
<automatically tune
<the transmitter to the correct frequency depending on 
<receiver's frequency.
<
< 
<
<After some initial trouble it's working reliably, but I don't 
<see any way to
<fix the RX frequency so that it only changes the TX QRG.  When 
<I enable CAT
<it changes both QRGs RX and TX.
<
< 
<
<It's cumbersome when making a QSO with a station which fixes 
<his downlink
<frequency and SATPC32 is constantly retuning the receiver.
<
< 
<
<Is there a way to configure SATPC32 so that it only changes TX QRG to
<compensate Doppler according to a fixed RX frequency?
