    For simplex it’s 16 for off-roading and 19 or 20 for general calling. For repeaters I don’t know if there is one.

    Cycle through the menu choices. See Basic Use below:

    Menu + 10 chooses the language.

    From weather.gov: (3) The most common inversion is the radiational inversion. The earth is cooled at night by longwave radiation emission to space. This is maximized on clear nights with light wind and dry air. Air in the lower PBL will cool much more rapidly than air at the top of the PBL at night. This will cause an inversion that at times can be quite impressive. These inversions generally erode rapidly once daytime heating warms the lower PBL.

    Is there an adjustment on the antenna to shorten the element?

    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?
  19. SteveShannon
    Thanks! I will.
  20. SteveShannon
    Just look at reliability figures for the 4Runner versus any Jeep.
  21. 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.
  22. SteveShannon
    As long as it’s a 4Runner (or Sequoia or Land Cruiser).
  23. SteveShannon
    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.
