    Mr

    $18 or $27 is still too much to pay for a paperweight. Let’s try to help the guy figure out the problem.

    Mr

    If there’s truly a password. As I said, the manual doesn’t mention one. Perhaps he simply locked the keyboard. Or maybe the manual is poor.
  3. An amplifier is a transmitter and transmitters sold for the GMRS service are required to be certified for part 95e.

    Mr

    The manual doesn’t mention a password. Are you sure you entered a password? Resetting the radio is menu 40. https://fccid.io/2AJGM-P15UV/User-Manual/User-Manual-5201622
  5. I’ve reported your post. It’s not a complaint, but it usually gets Rich’s attention. Good luck!
  6. If you hear them but they don’t hear you, make sure you’re on a repeater channel. You should be transmitting on 467.625 MHz.
  7. Most of us understood that it was a joke.
  8. One of the reasons repeater sites frequently use folded dipoles is that they have arrays of two or more of them to increase gain as well as to angle them downward from horizontal. They’re very durable and withstand high winds, plus they look cool.
  9. There are several good quality connectors such as Amphenol, M&P, and DX Engineering. The best are literally silver plated, but unless you string together several of them in a row the advantage probably won’t make a lot of difference. But there are some shitty connectors out there also and one of them could cause issues. I choose to buy connectors and adapters from companies I have faith in like DX Engineering unless it’s for the junk box.
  10. Also, if you’re in a location where both repeaters have strong signals, you may get interference. Tones do nothing to prevent interference.
  11. This report is not related to the exact problem Randy has described, but it might help understand how to report the interference. It would appear that the military takes complaints seriously. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-172R/html/GAOREPORTS-GAO-06-172R.htm
  12. The 22 FRS frequencies are exactly the same as the first 22 GMRS frequencies. There’s absolutely no difference in the frequencies but there are differences in the power limits. None of the 22 are reserved exclusively for FRS.
  13. No, reverse polarity has nothing to do with electrical polarity. RF is AC. SMA connectors have an outer threaded sleeve and an inner pin/socket. Sometimes the SMA connector on the radio will have the male pin paired with the female threaded sleeve. The antenna will have the female center socket surrounded by a male threaded sleeve. But it’s possible to order SMA connectors that pair the male threaded sleeve and the male center pin. The matching connector will be the female sleeve and female center connector. So there are four permutations of the SMA. I don’t know which is considered Reverse Polarity. I just buy what looks right. Most of my radios have a female threaded socket and male center pin, but one has a male threaded sleeve and female center socket. Just be careful to exactly match the mechanical configuration.
  14. There is a switch. Immediately below the original question, over on the right, is a pair of buttons. You can choose to sort by VOTES or by DATE.
  15. HamStudy is the way to go. It’s free to use, but I would encourage people to buy the app for their phone or tablet and study using it when they’ve got some time to kill. Much cheaper than the ARRL books and it changes when the questions change and it really allows a person to follow a subject to the level of detail that appeals to them. I used HamStudy to study successfully for all three tests without owning a single ARRL book (at the time anyway; I’ve picked up some since.) I really enjoyed using HamStudy (if it’s not apparent .)
  16. Well, first, only the GMRS transmitter is certified. That’s 95.1761, parts a-e. The regulations say nothing about certification of receivers. https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E/section-95.1761. Second, the FCC established channels in 95.1763, parts a-d. According to 95.1763(a), Repeaters may only transmit on the eight channels called out in 95.1763(a) called the 462 MHz main channels. Third, the 467 MHz main channels are established in 95.1763(c). The limits here are a little more subtle: 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). So, those eight channels are specifically reserved for transmitting to a repeater (or by the debate inspiring Fixed Stations) and their frequencies are intentionally spaced 5.000 MHz from the eight channels set aside by part a, so it’s both convenient and the convention to establish repeater pairs that take advantage of the spacing and that’s how GMRS radios are manufactured, but nothing prohibits configuring a repeater to receive on any of the 22 channels established in parts a, b, or d and no regulation that I can find prohibits transmitting through a repeater on those 22 channels. Silly maybe, maybe even useless, but not non-compliant. Think of how confusing that could get.
  17. You wouldn’t bork your radio with the wrong adapter. It just wouldn’t fit. Just make sure it looks like what you’re adapting to.
  18. No apologies needed on my behalf. I was just explaining.
  19. He mentioned that in his review. I think he’s trying to find out if anyone else has received it.
  20. Although they’re programmed this way, no regulation requires it. It’s inconvenient to people that buy GMRS radios, but there are several examples within the pages of this forum of repeaters that have a non standard offset, yet comply with regulations.
