Where do I run my Digital HotSpot (MMDVM, RaspPi, Zoom, etc)?
The recent increase in popularity of frequency-agile “hot-spot” devices, especially for
digital modes like DMR, P25, NXDN are usually low-profile, neighborhood devices and
likely will not need formal coordination. Guidance for where to run them would be in the UHF 420-432Mhz range below frequencies for links or international satellite
allocations. Most modern radios cover the full 420-450 amateur range so this should
be adequate for most needs. If you want a higher-profile installation, please consider
requesting a formal coordination and using a narrowband emission for maximum sharing of our spectrum
