I prepared a video to cover all the basics of thevarious LoRa and RFM69 transceivers used on Moteino boards. I concentrated on the most common topics I've seen show up in the forum and in support emails. This should be a good primer for those getting started with using sub-Ghz transceivers with Arduino or Moteino or even other compatible boards, since most principles apply the same way.

I also made a video about the new PCB Dipole Antenna, a significant upgrade from the previous version. This has a nice VSWR of almost 1.0 at both 868Mhz (at default 78mm length), and 915Mhz (trimmed at 73.5mm). It could be trimmed anywhere down to 2.4Ghz but it will be a best performer for the wideband LoRa and FSK radios in the sub Ghz ranges. For more details and theory on dipoles be sure to check out the dipole section in the RF-Best-Practices Guide.
