Lscott Posted 3 hours ago Report Posted 3 hours ago Well I just got a clean looking license free TK-3701D dPMR446 radio, NOT DMR446, which is the other allowed digital mode. The idea is to run some tests between it and the Icom's I have with the more functional dPMR digital voice mode. I want to see if they will communicate. There are some slight differences that might bugger it up. I won't know until I can get around to running some tests. Other thing there radios are the functional equivalent of FRS here, but in the EU where it's license free, 0.5 watts, and digital voice is allowed. I'll bet some Ding-Dong will bring their radios here on vacation and try to use it while at some major tourist attraction like Disneyland, Yellowstone etc. The radios only work from 446.0000 to 446.2000, the Ham 70cm band. Anyone ever bump into something like this on the air? If one has a spectrum analyzer, or SDR, it would look like the ultra narrow band NXDN mode, the modulation is the same but the digital protocol is different. https://kenwoodcommunications.co.uk/files/file/comms/uk/brochures/TK-3701D_20191030_LR.pdf https://kenwoodcommunications.co.uk/files/file/comms/uk/pmr446/PMR446-White-Paper-V6_18AUG2016_JT_KB.pdf Quote
WRYS709 Posted 3 hours ago Report Posted 3 hours ago Are there any “legitimate” domestic (US) uses for this radio? Quote
