  1. Nope. Tuning step has no bearing as the channels are fixed./
  2. Being the south end of a north bound donkey?
  3. My playing with some Retevis handhelds show they do have a CTCSS code enabled. It's been a couple months since I went into them but if I remember it was 127 or 185 as the primary digits.
  4. Th FCC says HOSs can't ban dishes.
  5. Retevis radios DO have a CTCSS code installed from the factory. That's why they state they only talk to each other but offer a CPS to change or remove the code.
  6. As a follow-up, it also depends on the repeater's receiver. If the repeater is a retuned commercial/public safety unit, the receiver will be more sensitive to RF than a Retevis or Midland "suitcase." Your carrier signal that carries your voice can reach further than the rest of your signal.
  7. Yes.

    No. Licenses are issued to individuals only in the Personal Radio Services. However, you can use FRS freely within your group.
  9. Welcome
  10. 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.
  11. Channels 1-22 used to talk to someone close Channels 23-30 used to talk to someone not as close lI
  12. Full cans act the same as a dummy load.
  13. 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.
  14. 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.
  15. My recommendation is to use a wire rope with thimbles. https://www.amazon.com/dp/B0CSYLQCXB?asc_source=01HFY6QA52QM8M7ATBSHXHG6T4&tag=snxs23-20&th=1
  16. 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.
  17. Do birds roosting on the spider wire cause interference or just loss?
  18. Use Repeater Book. You can specify listings by highway in each state you are planning to visit.
  19. 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.
  20. Misspelled - should have been bring the antenna down (closer to ground level).
  21. 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
  22. Search for FT-4XR unlock on YouTube. (
  23. 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.
  24. 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.
