Hi Craig, OSCAR is an acronym for Orbiting Satellite Carrying Amateur Radio, but yes, in this case we were talking about AO-51, which is an acronym for "AMSAT OSCAR 51" :-) There are also other AO-51-like satellites (i.e. single channel FM voice repeater) e.g. AO-27, SO-50 and SO-67 - you can find a complete list with transponder frequencies on the AMSAT website: http://www.amsat.org/amsat-new/satellites/status.php > Also, you mention the TVRX. Why is this important vs what I have? We mentioned TVRX daughterboard for USRP because it covers 50-800 MHz and AO-51 often transmits on 435.300 MHz and you can not receive that frequency with DBSRX daughterboard. You need either TVRX or RFX400. Note that the 2.4 GHz S-band downlink on AO-51 is not always active. In fact, it is switched off most of the time according to a schedule, so worst case you will have to wait several weeks for the S-band downlink of AO-51 to be active. You can see the schedule here: http://www.amsat.org/amsat-new/echo/CTNews.php I hope this clarifies it.
