JLeikhim Posted October 13, 2021 Report Share Posted October 13, 2021 Geez does it ever end? The waiver granted to Motorola is not as benign as one thinks. When you add up a few dozen radios automatically reporting GPS location on one channel, the noise and interference will be horrible.

Radioguy7268 Posted October 13, 2021 Report Share Posted October 13, 2021 I would agree. Allowing any type of automated GPS updates will kill channel capacity even if you've got just 5 or 10 high power units reporting GPS location every 30 seconds. I haven't looked deeply enough at the rules - but is the FCC requiring units to monitor the channel prior to transmitting their "brief" data burst? Automated location updates on repeater channels would be a disaster. I can see a point to allowing units to update automatically once every 10 to 15 minutes - or alternatively, tagging on to the beginning or end of a voice transmission like a PTT ID.

If there is no requirement for a BCL, busy channel lockout, that would be worse, automatic interference. I also think you wouldn't want this on a repeater channel. That has the potential to block a frequency out over a very wide area if the repeater was activated. If were are going to tolerate GPS updates why not have it restricted to one channel only leaving everything else open for normal traffic? In the Ham world there are several frequencies in the band plans set aside specifically for packet and APRS. Keep it on one of the 8 low power, 1/2 watt, FRS channels. They are sort of useless for GMRS as it is. pcradio, wayoverthere and Radioguy7268 3 Quote Link to comment Share on other sites More sharing options...
JLeikhim Posted October 13, 2021 Report Share Posted October 13, 2021 The FCC has clearly not thought this out and is relying on the assertions of the manufacturers. I don't believe there is a BCL lockout requirement. Only a duty cycle that is insufficient given the multitude of radios that might appear on channel in an urban area or national park.

mbrun Posted October 15, 2021 Report Share Posted October 15, 2021 Does anyone have a link to an audio file of what the existing data transmissions sounds like that the current legal crop of GMRS radios with location and texting data bursts produce?

tweiss3 Posted October 15, 2021 Report Share Posted October 15, 2021 Turn to 144.39MHz and see if you would ever be able to get a word in. Now think you had out a handful of radios to family members and just let them go. JLeikhim and Lscott 2 Quote Link to comment Share on other sites More sharing options...
