    I’m confused. Were you transmitting through the duplexer with your handheld? Otherwise I’m not sure how an antenna and feed line allow transmission but block reception. Did you have a receive tone set and tone squelch turned on?
  2. SteveShannon
    But what were those changes?

    Try putting in spaces or “none”.

    He already solved the problem by switching to better power connections.

    It’s also noteworthy that Rocky Talkies are FRS only, not GMRS. Repeaters are not allowed on FRS frequencies.

    Then troubleshoot the base. You may be able to compare its circuit to the Baofeng base circuit. They might even be the same inside.

    Nothing. Not everyone thinks the same way and it’s easy to call someone a troll.

    One alternative is to figure out why it’s not working. Use a multimeter and troubleshoot it. Is it the base or is it the power supply? Many of the power supplies are interchangeable. I have four different handheld radios and three of them use wall warts that can be directly interchanged to use with each other’s charger bases.

    Are you certain you’re not in the GMRS call sign box? I just edited my ham call sign and deleted it completely with no problem. I’m going to go replace it now. But, you must have a GMRS call sign to be here. Try this: enter your GMRS call sign in the box that won’t let you past. Or maybe it’s like you suspect and “they” are toying with you. ?

    The Internet is not the public switched telephone network, nor does it use the PSTN unless you’re using dial-up internet.

    “Sweeping the antenna” means taking a series of SWR readings throughout the desired frequency range. By doing this you can see the SWR for the antenna throughout the range and where the antenna has the lowest SWR. You say you have a NanoVNA so you have the tool for the job. Be sure and calibrate the NanoVNA to that frequency range first, using a the no-load, short, and 50 ohm devices that came with the NanoVNA.

    Check the cover of the manual. The manual for the 935 has 56 menu items. The 935 is not the same radio as the 905. The manual for the 905 has 35 menu items. As others have told you, you’re looking at the wrong manual.

    Our GMRS licenses are specific with respect to frequencies. I don’t know if new licenses would be issued if the agreements changed.

    Whether that’s true or not, the purpose of this post was not to discuss the cost/benefit ratio of Ed Fong antennas, but to invite folks to attend a zoom presentation by Dr. Fong. Although I’m not the OP, I think we should respect the original poster’s hospitality.

    The vast majority of patents are based on new applications of existing knowledge.

    Well, no, he didn’t patent the J-pole. He has two patents that cover specific collinear combined j-poles for use on multiple bands. https://patents.justia.com/inventor/edison-fong He has 11 patents so far, with two of them being for his designs featuring collinear j-pole designs.

    Tesla is. If my short term memory serves me, the ten most American made cars are Teslas, one Lincoln, one Jeep, and Hondas. There are no Toyotas or GM cars in the top ten.
  18. SteveShannon
    Yes, you should be fine. Depending on the fuse type and tolerances, one would blow before the other.
  19. SteveShannon
    Price
  20. SteveShannon
    I’m guessing that is an empty set.

    Does Ubuntu use the full speed of the USB 3 port or fall back to USB 2?

    Here’s an ampacity table for automotive applications: https://jascoautomotive.com/automotive-wire-amperage-capacity-chart/

    Those currents result in raised temperatures in the wire and insulation. For house wiring, which is admittedly conservative, 12 ga. is rated at 20 amps.

    I resemble that remark, myself. ?

    Not only is the license easier to get, but that one license covers your entire extended family. No other licensed service has such licensing.
