gr-tnc_nx does not compile

[kevincroissant]

Hello,

I am trying to decode telemetry from BEESAT-9 to test the ground station I am building for Bobcat-1, and am unable to compile this module. System info:

/home/kevin/gnuradio-oot/beesat-sdr/gr-tnc_nx/build [git::master] [kevin@nitrogen] [15:37]

I believe I had this working before, about a year ago, when I decoded telemetry from an earlier BEESAT. So I think this may be an error caused by a package being updated and breaking compatibility. Please let me know if you need any more information.

This also does not compile on the new GNURadio 3.8.0.

Hi Kevin, thank you very much for the report. Since this was already reported by others (https://twitter.com/pe0sat/status/1147768774151606272), I will have a look at this, as soon as possible.
