Just a reminder - since the low data rate telemetry is subaudible, you
will likely need to use the 9600 baud data out pin (and select the
9600 baud packet mode in the 817 menu) to get the unfiltered audio for
decoding telemetry.

I don't think it decoded anything, but since the telemetry is "sub-audible" I imagine it got filtered out by the HT. The squiggly lines on FoxTelem seemed to react to the noise, so that confirms that it's hearing something.
