    It might, but it might not. It’s possible that it could because of the temperature inversion. There’s a website that predicts the possibility. I’ll try to find a link.

    Tropospheric ducting.

    Try it, but I have no idea how a stationary permanent magnet could affect a radio.

    Welcome!

    I would agree that it’s probably the cable or connector. I assume you’ve unplugged and replugged the connector several times. Sometimes a bit of lint or dirt can really mung things up. If you have a friend with the same radio try their microphone to see if it helps. You might be able to determine whether it’s the microphone or the radio. Good luck!

    It’s not a regulatory limitation. NVIS would work at CB frequencies as well. But, the range of bands available to us hams certainly makes it easier to experiment with things like this. If you try it, Terry, let me know how it goes.

    The thing is it takes a lot of transmitted power difference to result in a very audible reception difference. This video really demonstrates that point. The presenter demonstrates the difference in received signals at different power levels starting very low (5 watts) and goes all the way up to 600 watts where the signal is received with full quieting. This is for SSB rather than FM and the distance is heard over a 600 mile distance:

    I’m surprised it’s that high. Does there seem to be a clear difference between which are unlockable? For example I would expect purpose designed GMRS radios like Midland, Garmin, and Wouxun to be unable to easily be unlocked. I would also have guessed that the Baofeng radios are nearly all easily unlocked.

    You’d be amazed how quickly deer will become complacent to a new structure. Shiny barb wire fences, busy highways, farm equipment - within a few days they completely tune them out.

    I did and I put power poles on the plug end as well so I can still use the cigarette lighter power.

    Jeep is owned by Stellantis, a Dutch corporation. So it’s literally a Dutch car company building Jeeps in Toledo, Ohio from 70% US parts and 30% foreign parts.

    Apparently your radio always thinks that B is the sub-channel. Perhaps when dual watch is disabled that’s how it works?
  14. SteveShannon
    Thanks! I will.

    Just look at reliability figures for the 4Runner versus any Jeep.
  16. SteveShannon
    Dual watch simply means both tuners are being monitored (watched). On my radios if I turn off dual watch only one tuner is shown and heard.
  17. SteveShannon
    As long as it’s a 4Runner (or Sequoia or Land Cruiser).

    That’s right; that’s what it does. You have two VFOs, A and B. Either can be the “main band.” The other is the “Sub Band.” If you don’t want to be interrupted by the Sub Band, you turn on Sub Band muting using one of the three options. If you choose RX/TX while in one band the other band will always say “Mute.”

    Except ours has locked up twice in the winter in two years, requiring us to wait until the snow melts to power fail it.

    Did you find it in the database and ask permission? They usually provide you with the tones if they approve your request. Actually it’s an open system and the tones are published right on the repeater information page: https://mygmrs.com/repeater/6174

    And if you mess with the meteorological satellites how would the guvmint control the weather and send hurricanes at their foes?? (Joking!)
  23. SteveShannon
    Not necessary. There’s no DC in your coax. In fact most people use a magnetic mount and the only “connection” to the metal roof is via capacitive coupling to allow the roof to be the ground plane. If you have a non-ground plane antenna you don’t need to worry about ground.
  24. SteveShannon
    Welcome! Grounding an antenna is not the same as providing a ground plane. In order to provide a ground plane you need a metal plate, such as a metal roof or hood. In your case I would suggest buying an antenna that doesn’t require a ground plane. I doubt that you need any kind of a ground strap.

    Welcome! Enjoy the perusal!
