New Packet Radio Trial Internet Connection - 2023 March

Last year, we evaluated how well New Packet Radio would work on our 0.7 cm band.

Winlink email with an 85 kB DFU file took 20 seconds over NPR at Modulation Mode 11 from field to GMail (through the EOC and Winlink Global Email system via Telnet). Winlink reported 156 kB per minute.

The same 85 kB file takes much longer over 1200 packet; 30 minutes at 3.3 kB/min to send with 1200 packet over radio with the RMS radio in the same room, or 4 minutes at 22 kB/min with 9600 packet (or less than 1 second at 746 kB/min with Telnet over 100 Mbps Ethernet).

Mode 11 needed very strong signal to get 0% bit error rate (better than -80dBm).
