Can you do APRS? AX.25? Or let me know how you can use the old RTTY for it, very curious!

- jgrahamc 16y agoI want to downlink some pretty simple information: lat, long, altitude, temperature, so I think RTTY should be good enough. There are some nice modules by Radiometrix which work on 433Mhz (unlicensed band in the UK) (e.g. http://www.radiometrix.com/content/ntx2 http://www.radiometrix.com/content/ntx2). The CU Spaceflight folks have been using these modules at 50 baud. I think I'm going to stand on their shoulders for this part. http://www.radiometrix.com/cu-spaceflight http://www.radiometrix.com/cu-spaceflight
