Hi Gene,

USB for both the up and down links.

Check for the beacon at ~29.457.

The RS-13 transponder does not invert, so whatever you send up comes down
the same, translated to a different band.  Since all downlink frequencies
are above 10mhz, by convention, as for terrestrial, most ops use USB.
However, that is merely convention.  It is perfectly permissible to use
LSB, but the listeners will be listening for USB.

Did you get a satisfactory answer?  I am going by memory on this.  RS12 is
a NON inverting satellite which means if you put in USB then you get out
USB.  The convention is to use USB on the downlink so I would start with
both up and downlinks on USB.  Cliff K7RR


Thanks again everyone.
