1) GMRS stations may be operated by remotely control.
That is true, and has nothing to do with the issue, which is not control of GMRS stations at all. The issue is connecting stations to the Internet for audio.
2) GMRS stations cannot be connected to a telephone (telephone interconnect).
That is also true, and has nothing to do with the issue, which is not connecting to the telephone network. The issue is connecting stations to the Internet for audio.
Two straw-man arguments so far.
3) GMRS stations may be remotely controlled by the PSTN (a new clarification) or the Internet ("Other networks")
True but irrelevant, because the issue is not remote control of a station. IP audio via GMRS is not control of a station, whether remote or otherwise.
Control means causing the station to transmit or cease transmitting -- the age-old official definition of control of a station -- which is not "messages" or "communications" as the FCC calls it.
How do you turn your repeater on and off? Do you do so with a switch on it, or is the switch somewhere else? That is remote control.
Interconnection is allowed for the "sole purpose" (only purpose) of remote control -- and for no other purpose.
This has been discussed and argued at length.
And people still reach the wrong conclusion.
There is even an e-mail response from the FCC stating "there is no prohibition on linking repeaters via the internet".
The e-mail response isn't worth the electrons it was written on. Even people who like that response concede that the FCC "doesn't understand the Internet."
The person who wrote that response is clueless, a fine example of why the FCC has repeatedly said that those who rely on informal staff interpretations do so at their own risk.
And for the record, while the e-mail makes a big deal out of ISP choice, the Enforcement Bureau (which did not write that e-mail) very likely doesn't give a hoot whether your ISP is a telco or a cable company.
If you pay close attention to the FCC enforcement logs you will find there are ZERO NOV's for linking GMRS repeaters. I challenge you to find any enforcement action or official notice from FCC EB citing such prohibition. They don't exist.
Another straw-man argument. There are probably thousands of rules that have had no enforcement against them. And GMRS is low in enforcement priority. I never asserted that the FCC is coming after Internet linked repeaters.
I simply point out that the rule does not say what some GMRS operators want to believe it says. Should there ever be enforcement on it, operators will have to cover themselves with that silly e-mail and hope it works.
