  1. Don’t overthink it. Buy one and use it. Your hands-on use will tell you more than our analysis ever could.
  2. I think that those “altered elements” can be explained as notes that people made for themselves.
  3. Simulate them using mmana or eznec. The amount of power delivered to the array is fixed so using a splitter will result in only 25% of the power being delivered to each antenna. Without some kind of splitter you’ll have to figure out how to match the impedance an 18 ohm cluster of antennas to your radio. The propagation pattern coming from four Yagi antennas will not be nearly as circular as from a phased array of folded dipoles; I think you’ll have four large lobes with areas of cancellation between. But simulating them will tell you for sure. It’s an interesting idea, but if your goal is to create a circular pattern horizontally, start with an antenna that emits a circular pattern horizontally and use vertical phasing to increase the gain relative to the vertical axis.
  4. Make a post saying which repeaters are bogus then click on the three dots in the upper right corner and choose Report.
  5. Are you certain you’re dialing all the digits? Dialing fewer would result in a dead line like you described.
  6. If someone reports them Rich takes care of them but if nobody reports them they might remain in place.
  7. Yeah, I remember when we opened up a “466” (as I recall it was a 486 processor running at 66 MHz) computer case and the security guy’s handheld went ape.
  8. I completely agree, Kenny. I also cannot find anything on either FCC or ISDE sites other than the limitation expressed on the license. I wonder if this is simply a case of someone neglecting to update the license text.
  9. It could be a battery charger, one of those wall warts, a computer power supply with problems, fluorescent lights, LED lights, almost anything. Unplug things until it stops. Such noise is not uncommon.
  10. The specific restrictions are not in parts A and E. I don’t know if they ever were. Because changes to regulations are subject to the NPRM process by law, a better way to link regulations to treaties is by reference, which is done in 95.309, the superior portion of part 95 that affects all of the subparts: § 95.309 Coordination procedures and other restrictions for operation in certain locations. The operator of a Personal Radio Service station may be required to coordinate operation in advance and/or may be subject to operating restrictions if the station is to be operated in certain locations, described in the following paragraphs in this section. (b) Near a U.S. border or in an area that is or may be subject to an international treaty or agreement. Treaties and agreements may be viewed or downloaded from the FCC Web site: http://www.fcc.gov/ib/sand/agree/. The link in the quote leads to a bunch of agreements. The treaty that initially set aside Line A is referred to loosely as the Above 30 MHz Agreement, but there have been amendments and other treaties since 1962. I never have been able to find something other than my license that specifically states I cannot use channel 19 above Line A, so I really don’t know where to go to verify it. If new licenses continue to include that wording then I will avoid using the channel.
  11. My first thought was to see if Wouxun has an FRS radio. They have an FRS version of their 805. https://www.buytwowayradios.com/wouxun-kg-805f-two-pack.html?fee=5&fep=5285&utm_source=google_shopping&utm_medium=feed&utm_campaign=product_ppc&matchtype=&keyword=&device=c&adposition=&network=g&gad_source=1&gbraid=0AAAAAC4SJ1idKy2EUZLQOnDFF8I9Rl-z1&gclid=Cj0KCQjw-5y1BhC-ARIsAAM_oKnUq5DVMsuZesWEiOFTuP0NgNb_x5-y_uFyqh7IXHCv-CiS1rDtpQQaAlTxEALw_wcB
  12. 500 feet certainly should have been enough. In that case I have no idea what is causing the MXT115 to stop receiving after the first few seconds. Is it only transmissions to the MXT115? Are transmissions from it to other radios okay?
  13. I considered mentioning that, but my license was printed almost three years ago. I don’t have a more current copy of a printed license.
  14. I gave a possible answer in the other thread where you asked the same question. Good luck!
  15. Separate the transmitting radio from the mxt115 radio by a greater distance and see if the problem continues. Your MXT115 might be desensing (going deaf temporarily because of a strong nearby signal.)
  16. Why do you think that, Kenny? Certainly it’s still defined on this page: https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-division/frequency-coordination-canada-below
  17. Tonkatoy only made two posts nearly six years ago and hasn’t been online here since 2022.
  18. Did you try right clicking on the executable and selecting “run in compatibility mode”? Also, you can type alt+prt SCR or ctrl+prt SCR to take screenshots rather than using a camera.
  19. Off road -> 16 On road-> 19 (by Queen decree) Those of us who live near or above “Line A” reserve the right to disregard His Majesty the Queen.
  20. No, if it’s a ground plane antenna it needs to couple to either the roof, hood, or trunk lid somehow (or a sheet of conductive material of some type), otherwise it will not receive well. But it can do so capacitively even through a layer of paint or thin plastic or rubber. I’m saying it doesn’t need to be an DC electrical connection that can be verified with an ohmmeter. Because it’s RF a layer of paint isn’t an impediment. Nobody sands off the paint to use a magnetic base, right?
  21. The traditional use of the word “skip” applies to hf radio signals bouncing off the ionosphere. UHF doesn’t do that, but it does propagate long distances sometimes when there’s a temperature inversion which causes tropospheric propagation, also called tropospheric ducting.
  22. I don’t see how my question strikes you as a negative comment. I was just surprised to hear you suggest 11 meters needed more users when many users of GMRS are upset about congestion.
