  1. I used to chase down such interference for Motorola and it happened many times. Bad power amps, bad isolator panels. Once a 220 MHz ham repeater plus FM broadcaster mix. Sometimes lightning damages stations and they go bananas. . Sent from my SM-T350 using Tapatalk
  2. Yeah if the repeater starts interfering with Public Safety after hours or on a weekend you definately need to be able to shut it down. If the FCC calls you and it is stuck on, do you have access to the repeater? Sent from my SM-T350 using Tapatalk
  3. Same as when I won the lotto.. Sent from my SM-T350 using Tapatalk
  4. Your freinds can use FRS equipment and you can communicate with them on a shared FRS/GMRS channel. But no, they cannot use your license. Even temporarily. They need their own license as GMRS licenses the individual and immediate family, not the station itself. Sent from my SM-T350 using Tapatalk
  5. This is what is so very confusing about the MXT400. It is not FCC certified for wideband operation. If this software indicates anything whether narrow or wideband, 12.5 versus 25 KHz channel steps etc, . It really needs to be confirmed with a deviation meter and other measurements to confirm the radio is wideband. You could simply be toggling bits in the radio firmware that do nothing. I don't believe these MXT400 radios are capable of wide band at all. If they are, Midland could potentially get hate mail from the FCC for releasing the software to modify a certified radio .

  6. They used to make some pretty good LMR gear. The early low band repeaters no so good. Sent from my SM-T350 using Tapatalk
  7. Disappointing that the Midland Personal Radio rep can't talk intelligently about those subjects. I don't think Midland wants to see GMRS as anything more than a consumer toy. If customers were knowledgeable, they might buy radios with better specs and features. Funny that Midland does not make GMRS repeaters. The problem may be the corporate structure as they do have , (or once did) a land mobile radio division that once made some fair to midland (pun intended) mobile radios.

  8. I think the lesson here is that if all you want is a cheap simplex radio to talk short distances in your group, then by all means buy a couple Midland radios. They will unfortunately be low performance narrow band radios by design. If you want to talk through repeaters and talk to other licensees, you need a commercial grade radio like many of the Kenwood radios. They are plentiful from used market at cheap price. They will have wide band capability, better receivers, multiple CTCSS ( PL ) / DCSS (DCS), split tone , repeater capability. Etc Sent from my SM-T350 using Tapatalk
  9. I think his dual band base antenna is presenting a ton of signal at 155.850 MHz and his Chinese receivers are overloading and creating third harmonic on or near 467.6375 MHz . A quick check would to put a UHF single band whip on the radio and see if the signal is radically reduced or goes away. It is too coincidental that the third harmonic falls right on channel. I would not rule out a spurious signal from the sheriff repeater, but we are talking about a $30K repeater and duplexer versus a $35 Chinese receiver. Any bets? Sent from my SM-T350 using Tapatalk
  10. I ressurected some Motorola Securenet DES equipment. It sounds much better than P25 and has a 12 Kbps CVSD vocoder that was designed in the 1980s. Sent from my SM-T350 using Tapatalk
  11. Yes, I think your receiver is likely the problem. Sent from my SM-T350 using Tapatalk
  12. My distance to horizon calculator begs to differ... Sent from my SM-T350 using Tapatalk
  13. I am still waiting for the announcement. Maybe they are waiting for stock to be depleted on the older models? Sent from my SM-T350 using Tapatalk
  14. I had no affiliation with ARISS and as far as I know ARISS does not control private contacts with the ISS. Nor does ARISS have any control of the airwaves. I was requested by local ham club to set up my station at a private event at a new museum. Instead of them politely inquiring what my involvement was I got bashed by so called "ARISS officials". I was just the guy who accepted when asked to volunteer my time and equipment. Very bad PR on their part. They could have been supportive if that is their charter, but instead chose to be asses. So no, no demo from me. This was a long while back, but left very bad taste for that org. Sent from my SM-T350 using Tapatalk
  15. Some years ago, a science center opened up near where I used to live. The local ham club asked me to move my satellite station there for an ISS contact. So naturally, I volunteered. Big mistake, next day, word got around to ARISS and I got all kinds of nasty messages from the ARISS folks saying I could not do that. Great way to treat volunteers.

  16. There was an FRS to FRS contact in Washington state some years ago that was over 70 miles. A hiker got injured, called for help and kids playing with FRS heard the call. This was between mountains. Sent from my SM-T350 using Tapatalk
  17. I have a bunch of Ritron DTX450 data modules that are based on the Patriot. Sent from my SM-T350 using Tapatalk
  18. That is very cool indeed! My best was some 2M SSB from Tallahassee FL to Texas and once to Clingmans Dome in Blue Ridge Mountains . But both times I had over 100 watts at 90 feet AGL and a RX masthead preamp. So your walkie at ground level GMRS is damn impressive. Sent from my SM-T350 using Tapatalk
  19. I like option 2. Perhaps social media can encourage local participation during the holidays. Sent from my SM-T350 using Tapatalk
  20. Isnt this a done deal? I don't see any reply comment period. Sent from my SM-T350 using Tapatalk
  21. Maybe, but I did a search for some other xxxx600 named repeaters and some were also .550. Also Hans said his was wrong as well. Odd.
  22. On or before (*) 6/21/2021 my repeaters frequency was altered in the database. I don't recall any reason to have logged in and done that. Another owner has told me his was changed as well. (*) Date of weekly update email.
  23. There was a report of someone having desense between two cheap Chinese radios over a mile from each other line of sight. Sent from my SM-T350 using Tapatalk
  24. It would be a pretty indefensible position for the FCC if challenged to prove a licensee's use of a part 90 radio in a non-interfering manner was causing harm. The FCC would have to prove excessive power or interference directly related to the part 90 usage. The numbers of FCC NALs issued for GMRS operations is nearly zero. The few exceptions are flagrant business use of the repeater pairs. The biggest risk on the reputation of the service are the knuckleheads that operate without a license because "they are special".
