Not even with permission. 95.1787(a)(5) GMRS units must not be capable of transmitting digital data on the 467 MHz main channels.

0 kidphc Posted October 9, 2023 Report Share Posted October 9, 2023 Technically illegal.. with the recent changes they allowed gmrs to send data. Such as gps location and small text messages.https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E"Digital data. GMRS hand-held portable units may transmit digital data containing location information, or requesting location information from one or more other GMRS or FRS units, or containing a brief text message to another specific GMRS or FRS unit."But went as far as saying not over the repeaters."Digital data transmissions. Digital data transmissions are limited to the 462 MHz main channels and interstitial channels in the 462 MHz and 467 MHz bands""5) GMRS units must not be capable of transmitting digital data on the 467 MHz main channels"FCCs way of saying don't do it on the repeater inputs.Sent from my SM-S901U using Tapatalk RayP, Sshannon, WRUE951 and 1 other 4 Quote Link to comment Share on other sites More sharing options...
0 tweiss3 Posted October 9, 2023 Report Share Posted October 9, 2023 I wonder if he is hearing MDC1200 IDs, which aren't technically permitted over the repeaters, but are permitted on simplex. Quote Link to comment Share on other sites More sharing options...

Agreed, he could simply be hearing someone on simplex using a location sharing radio such as a Garmin, since the receive frequencies are the same.

0 kidphc Posted October 9, 2023 Report Share Posted October 9, 2023 Very possible many mdc users are ignoring the rule. To be fair though, it generally would sound like a Motorola roger beep.People would really hate the sound of digital over the radio, especially if they couldn't decode.Tune into 144.390 with no pl, see how long your sanity last. Most hams turn on receive pl or stay away from the aprs frquencies.Sent from my SM-S901U using Tapatalk RayP 1 Quote Link to comment Share on other sites More sharing options...
