Baofeng UV-5R Portable Temporary GMRS Repeater - Part 2 - Operational Testing - Proof Of Concept

RPT-2K two way radio repeater interface box repeater connection cable relay duplex repeater interface Baofeng UV-5R Tone squelch on repeaters Require a CTCSS tone (tone squelch, PL tone) to open your repeater. 141.3 Hz is the GMRS “official” tone. 141.3 PL is also called the Travel Tone. It is recommended for 462.675 MHz - FRS Channel 20. 110.9 Hz 114.8 Hz 123.0 Hz 127.3 Hz 131.8 Hz 136.5 Hz 141.3 Hz FRS CALLING CHANNELS FRS Channel 1 - 462.5625 MHz FRS Channel 20 - 462.6750 MHz FRS Channel 3 - 462.6125 MHz 462.5625 MHz No Tone (CSQ - carrier squelch) Ch. 01 FRS Calling 462.6750 MHz 141.3 Hz Ch. 20 GMRS calling 462.6375 MHz 74.4 Hz tone - recommend transmit tone only if possible - militia patriot prepper calling channel. Used in conjunction with MURS radio MURS channel 3 which is 151.9400 MHz and CB Radio Channel 3 AM which is 26.985 MHz AM. Note that is is legal to use AM mode, FM mode and SSB on CB radio (USB and LSB are permitted). AM is the “standard” mode - the backward compatible mode. Now radios like the Cobra 29 LTD are being sold with AM mode and FM mode standard.
