When you stay tuned to new arrivals on Alibaba.com you occasionally will run into interesting products. The TID TD-M2100 (link) might be one of those (thanks to PA0TBS for the pointer).
Is it compatible with DMR-2? No. Is it dual band? Probably not, in spite of the suggested frequency range (136-520MHz). Is it dirt cheap? I’ll have to say “Yes”, somewhere between $100 – $120 is not bad for a radio combining analog and some form of digital voice.
Personally I don’t care about the lack of compatibility with other systems. Creating your own network might be just as much fun, and with the average price of a DMR-2 radio in mind you can buy a bunch of these and still keep money in your pocket.
