You may not legally connect any device to an FRS radio which has not been FCC-certified as part of that radio. This means that you cannot legally connect anything to the headset jack other than the headset (or other device) the manufacturer certified for that particular model of FRS radio. The FCC has not approved, and is not likely to approve, any phone patch or interconnection device for FRS radios. A first-offense violation of this rule will result in a fine of $10,000. GMRS and MURS radios have different rules. I would look to using them for this type of interconnection.

Would plugging into the headphone jack with a phone-patch-type device be considered a modification for radios with vox capability? ah ah so do ' phone-patch-type device' interface via the to frs/gmrs 2 way radios via the mic jack ? can someone that know this stuff point out a few urls of the phone patches ? is there such thing as frs/gmrs repeater that can send/receive on different frequencies at the same time to acheive a duplex conversation ? ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

There are GMRS radios that support frequency splits...

[Asterisk-Users] Re: FRS and GMRS via *
You don't need to reinvent anything to tie radios to *. Ham systems like IRLP, Echolink, eqso etc all have fairly tight controls to keep from being abused (although with a little Linux knowledge, the IRLP package can easily be used to set up your own network using their protocol). Jim Dixon seems to have done the work to integrate radios with * already. See http://www.zapatatelephony.org/app_rpt.html -- it's all there including a PCI card that interfaces to 4 duplex radios for $500 and a single card that interfaces to one radio for $100 (plus 2 FXS ports). For the rest of the details go look at the app_rpt application. There has been a lot of speculation on this list on the legalities of doing this. For amateur use under Part 97, interconnection with the PSTN is fair game *if* a licensed amateur is always in control of the transmitter and the transmissions are strictly non-business. Non-amateurs can talk over the system but only when the transmitters are being controlled by licensed amateurs. The line in the sand is that you can order pizza over the autopatch, but you can't order cheese for your pizzeria. GMRS, FRS and MURS radios may not be interconnected with the PSTN (47 CFR 95.141). There has been a lot of talk from lobbyists to clarify this rule, but as it stands you could conceivably connect a *private* network to GMRS or MURS radios (you can't make any plugins or modifications to an FRS radio that isn't type accepted with the radio, so connecting a phone line or * box would be out). The language is vague, see the history at http://www.provide.net/~prsg/ FRS and MURS radios may be used for business without a license. See http://www.provide.net/~prsg/frsrules.htm ... GMRS may be used for business too, but employees who aren't family members must have their own licenses. Certain commercial business radio channels in the Private Land Mobile service may be interconnected with the PSTN outside of major metropolitan areas (specifically, more than 75 miles from the population centers listed in Part 90 of the rules), or with agreement from all co-channel licensees in your area, and also on low power itinerant channels. It's not trivial to get a frequency coordination and license but you can run your own mobile telephone service under these rules and conduct your regular business that way. The radios are a little more expensive than FRS radios but you do have a bit more privacy and control over what happens. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
