Lscott Posted August 15, 2021 Report Share Posted August 15, 2021 Has anybody any experience with unlicensed use of European PMR446 and/or DPMR446 radios operating on the US Ham 70cm band? I would likely expect this around major international tourist spots like Disney Land etc. Apparently there are 3 different modulation types used depending on radio. Narrow band FM, TDMA (aka DMR), FDMA (similar to NXDN). https://en.wikipedia.org/wiki/PMR446 https://kenwoodcommunications.co.uk/files/file/comms/uk/pmr446/PMR446-White-Paper-V6_18AUG2016_JT_KB.pdf https://www.datamatik.no/media/produkt/tk-3701de.pdf Quote Link to comment Share on other sites More sharing options...
