  1. The regulation means the two services are not allowed to connect to each other using their assigned frequencies. A GMRS station is not allowed to use a cross-band repeater to retransmit traffic from any other service and the amateur service is not to use cross-band repeaters to carry traffic from any other service. This particular regulation just spells out specific services.
  2. Channels 1-22 used to talk to someone close Channels 23-30 used to talk to someone not as close lI
  3. Full cans act the same as a dummy load.
  4. I'd say it doesn't replace the shark fin as it only has the NMO mount and GPS antenna. Most shark fins have 3 or 4 antennas - AM, FM. Cellular, GPS and Sirius.
  5. The shape of the ground plane will have an effect on the radiation pattern as it will mimic the ground somewhat. The antenna will still be omnidirectional with a larger lobe in the direction of the greater area of the ground.
  6. My recommendation is to use a wire rope with thimbles. https://www.amazon.com/dp/B0CSYLQCXB?asc_source=01HFY6QA52QM8M7ATBSHXHG6T4&tag=snxs23-20&th=1
  7. I would place the antenna as close to the middle of the metal roof. That would be about where the rear crossbar is and in line with the fin. Your SWR could have measured higher on the right side because of something running just under the roof where the antenna was.
  8. Do birds roosting on the spider wire cause interference or just loss?
  9. Use Repeater Book. You can specify listings by highway in each state you are planning to visit.
  10. The codes are really filters that exclude transmissions not having the matching code. They don't offer "privacy" as any transmission can be heard by not using the filter code. Repeaters use input codes, t-ctcss, to limit the signals it retransmits. The R-CTCSS code in your radio screens all traffic not matching the code, but it's not really needed for receive. Having no receive code means you hear everything transmitted on the channel. So yes, you need to set the T-CTCSS but the receive is optional.
  11. Misspelled - should have been bring the antenna down (closer to ground level).
  12. Did you look at the radiation pattern for this antenna? Comet shows it having a very narrow lobe (around 20 degrees is my guess) so the power is directed at the horizon and not close to the ground. In order to pick up your friend a 1/2 mile away you will need to ring the antenna down or use a second, low gain antenna, I
  13. Search for FT-4XR unlock on YouTube. (
  14. I go to a local ACE Hardware and they have both SAE and metric set screws in stock. I then see what fits and use blue Loctite when installing.
  15. Probably the best solution for this would be a decent mobile antenna on a mag mount sitting attached to a steel baking sheet. If you wanted to stay with the antenna attached to the HH, I use ones from Signal Stick.
  16. Will that result in pickled contacts? I
  17. ??? Generally if you leave a battery-powered device on, the wattage in the battery decreases.
  18. On the railing your signal would look like a football if you could see it. Better EW but still usable for a shorter distance NS.
  19. Isn't that what I said?
  20. The railing will also work. The signal from your radio will be stronger going in the same direction as the railing, but still omnidirectional for all practical purposes.
  21. All repeaters are +5 - period. The gods at the FCC have spoken and we must obey. Unless a digital code is followed by the I (eye) it is normal.
  22. Reported to Rich
  23. As a Moxon is a variation of the Yagi, the driven element should be between the director elements and the reflector. the reflector is around 5% larger than the driven element and the directors 5% shorter as they go toward the front of the antenna. I'm not certain of the spacing between the elements.
  24. BS The key point is you need a compatible driver for the cable. Cables using the FTDI chjp/driver set are almost 100% interchangeable between radios. The only time I've found they aren't is when the radio requires a specific driver to access a proprietary feature found in their cable's chipset.
