APRS: 70cm LoRa vs 2m Packet

I've been having a lot of fun diving into APRS lately. And even more fun diving into LoRa. When you combine the two, you get something pretty close to magic. APRS over LoRa uses 125kHz of bandwidth, and on 70cm we've only been allowed to do that for a few months here in Norway. But in that short time, use of LoRa in general and LoRa APRS in particular has exploded. Join me for a short drive where I test and compare APRS over Packet on 2m with APRS over LoRa on 70cm. I connect a 100mW (yes, that's milliwatt) LoRa radio and the 5W (so; 50 times more power) Kenwood TH-D74 to the Diamond NR-770HB on a mag-mount on the car. I set out to do this little experiment to show that after only a few months, the LoRa APRS infrastructure is already in an impressive state. But I have to say, I was surprised at how good a job it does. Even with only 2% of the power, the quality of the LoRa APRS tracking was at least on par with the traditional APRS from the Kenwood TH-D74; maybe even better!
