  1. All repeaters have some kind of repeater controller. There’s an open source repeater controller built on the raspberry pi.
  2. A better antenna, mounted as high above your roof as possible (and the same on their end) might work.
  3. For GMRS Wyoming designated 307 (channel 3, CTCSS tone #7) because the entire state has 307 as its area code. I don’t know anything like that in Montana. Here it would be 406.
  4. Sven, I think you’ve lost your marbles, That’s exactly why you have call signs and why you’re required to use them: to identify yourself to others and have a way to look them up when you engage in the personal or business activities of “making contact”. Although it’s not explicitly encouraged like ham radio it’s absolutely not discouraged in any way, explicitly or implicitly.
  5. Absolutely not. First, you need a 50 ohm cable. Second, you need to keep the run as short as possible. If you can use 10 feet, use 10 feet. It should be something like LMR400 or better or even hardline. I recommend not ordering from Amazon. They’re not experts. They’ll just sell you anything. Instead use one of the professional radio companies or ham radio dealers.
  6. Or you try it both ways. You’ll see hams rotating Yagi antennas to determine the antenna orientation for the signal they’re chasing (mostly VHF and UHF).
  7. If the radio you are trying to talk to has its antenna mounted sideways (horizontally polarized) you’ll get better results by mounting your antenna the same way, unless the signal is bouncing off something which also can change polarity.
  8. That is correct. There are several other threads that started with someone pontificating about how others use GMRS incorrectly. None of them settled anything. This is one place where GMRS is similar to ham radio; someone thinks their way is “the only right way” even though the regulations don’t support that.
  9. We can break your bank guessing at what the problem might be. My feeling is that your antenna probably isn’t higher than the surrounding terrain and trees. Getting it higher can help but UHF does poorly in vegetation. Poor cable contributes by attenuating the signals in both directions, but antenna gain and visibility is by far the most important factor.
  10. That’s correct. But RG-59 has been replaced by RG6. Sell it to someone for use on HF or lower. It’s just not suitable for VHF or UHF.
  11. 50 feet of RG-58 would attenuate a buttload of UHF RF.
  12. So although the output frequency is 462.550, the frequency you must transmit to the repeater is 467.550 MHz. That’s usually taken care of automatically if you select a repeater channel.
  13. What kind of range are you getting? If people can use it when they’re near, the most likely thing you have “wrong” is simply antenna height, as @LeoG said. The other possibility is that your signal is being attenuated between your antenna and your repeater. What is “50-3 pure copper coaxial extender cable for RT97L”? What cable type is it and how long is it? Perhaps the 50-3 refers to the length? 50 feet three inches?
  14. Unless the output tone is different from the input tone … Which can be remedied by setting your radio to receive on the repeater input frequency and scanning tones.
  15. This doesn’t sound “utilitarian”. In fact it sounds pretty social. § 95.1731 Permissible GMRS uses. The operator of a GMRS station may use that station for two-way plain language voice communications with other GMRS stations and with FRS units concerning personal or business activities.
