GreggInFL Posted December 1, 2023 Report Share Posted December 1, 2023 I'm thinking about brining my GMRS radio to Germany, assuming there is anything to hear. I'll stay away from the PTT button, so there are no licensing issues. Thoughts? Quote Link to comment Share on other sites More sharing options...
Lscott Posted December 1, 2023 Report Share Posted December 1, 2023 They don't use GMRS in Germany. If anything its PMR446. https://en.wikipedia.org/wiki/PMR446 WRUU653 1 Quote Link to comment Share on other sites More sharing options...
GreggInFL Posted December 1, 2023 Author Report Share Posted December 1, 2023 Ah, got it. Yeah, 446 won't work. Thanks! Quote Link to comment Share on other sites More sharing options...

WRUU653 Posted December 2, 2023 Report Share Posted December 2, 2023 The low power and fixed antenna I would think limit these radios in comparison to our GMRS. Still I found it interesting to see how radio services are handled differently in other places. Quote Link to comment Share on other sites More sharing options...
BoxCar Posted December 2, 2023 Report Share Posted December 2, 2023 From one of the AI bots: Based on the web search results, it seems that the dPMR modulation mask is accepted by the FCC for operation in the US. According to one source1, “dPMR equipment complies with the relevant European standard ETSI EN 301 166 as well as the FCC emission mask applicable for operation in the US.” Another source2 states that “dPMR uses 4FSK at 2400 Bd. The dibits are mapped to +/-1050 Hz and +/-350 Hz from the center frequency. Because the emission mask is so tight, two 6.25 kHz dPMR signals can be used next to each other within a 12.5 kHz channel without causing interference to each other or adjacent channels.” A third source3 confirms that the dPMR modulation scheme would comply with the FCC emission mask mandated for LMRs to have a 6.25-kilohertz capability.

In fact there was a European version of a Kenwood NXDN radio that could be converted to dPMR per the brochure. NX-220E-320E.pdf Quote Link to comment Share on other sites More sharing options...
