Somebody here has try the NPR70 modems (New Packet Radio)?
Yes! So far only from one side of the back yard to the other, but they certainly work. You definitely need a little amplifier, because their output
is not very powerful.. but they are WIIIIIIIDE bandwidth. Like seemingly spewing all over the band kinda wide :). Still awesome they can achieve reasonably high data speeds.
Next step is to test them between my friend's house and mine with directional 70CM antennas. We can reach eachother with simplex voice right now, but
haven't been able to get the NPR70s to connect with the current setup. Their negotiation blips are super short.. it's just a very thin line on the
waterfall when watching the band with an SDR.
