These frequencies and pairs are outside the satellite range and common UHF repeater inputs / outputs, avoiding the influx of hotspot users from ruining the fun of other amateurs. The frequencies below have been established within the ARRL band plan and are acceptable to use for your personal hotspot. Second, you'll want to pick a frequency that is relatively free of noise within your home. ![]() You can hear a DMR repeater hundreds of miles away when there is tropo propagation. ![]() The admit criteria is your choice, but this is what it means. UHF Simplex 446.075 Our best 2-way DMR repeater DX is about 110 miles. Below are some frequencies you can choose from (in the US), dependent on a few factors.įirst, you'll want to make sure these are not in use already from a close neighbor. Please do not use the 2m (146.520MHz) or 70cm (446.000MHz) analog call channels for digital simplex, as they are not in the band plan for narrowband digital use. Many of these boards come from China with a defaulted option that may or may not work with your regional band plan. ![]() ![]() The Unidens and Whistlers seem to work about equally well for DMR signals. Many of those frequencies are used in DMR digital mode around here now and almost all are simplex. One of the first things you'll want to consider when setting up your new hotspot is what frequency (or for duplex, which pair) to use. I also monitor all the so called UHF and VHF business frequencies as listed here in the wiki and can't say I have any problems with DMR simplex signals.
