How Can We Help?
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.
Below is a list of recommended channels in the 420-432 Mhz range.
