Steve,

9k6 data is not used very much on AO-85 since it is not required for any of the experiments, and its use turns off the repeater. It is turned on, rarely and briefly, for testing or other purposes. There is usually an announcement on Twitter, Facebook and/or here in advance, though not always if they are doing a quick look. The Auto mode will pick it up, assuming everything else is working correctly at your station. It has been reported that the signal threshold to copy 9k6 is somewhat higher than for DUV.

Expect to see much more when Fox-1Cliff and Fox-1D fly.

73s,

Alan WA4SCA

Correct. I find 12-15 kHz works best on the AO-85 9k6 data with SDR#.

Do I recall correctly that in order to receive the higher data rate, a wider RF and/or audio bandwidth might be required?

I often have the audio bandwidth narrowed a bit (high end only) to better hear the voice traffic, which of course has no effect on the DUV as long as the low end of the audio filter is left at zero. Ditto on the RF bandwidth if it makes the voices easier to copy on a given pass.
