  1. DMR will only increase the channels if used in TDMA. Rarely that happens. And why should P25 or NXDN be pushed aside for DMR ? That's the issue. Only so many channels for repeaters. And why should an analog user who has had a repeater on the air for 20+ years be interfered with because someone bought a license and put up a DMR repeater in the same area. I know this can happen in Analog also. Still doesn't make it right. Linking should not be part of the digital standard. Again I get baffled by trying to make GMRS another ham band. Its one service that has some basic rules that anyone can spend the money on and get a license and use. As said earlier there are many places you can go use DMR, Fusion, P25, and NXDN outside of the GMRS service.
  2. Personally as much as folks want digital I think its in FCC and evey one best interest to stay analog. There are only a handful of repeaters for GMRS and if we add in DMR, P25, NXDN then it will turn into the ham bands. If you really need digital get a ham license or another license and use that service.
  3. Commercial VS Amateur Radio. Commercial radios will always be better. Less bandwidth and better filtering.
  4. No the ghost antenna is about as effective as a dummy load. Think of it as your portable radio antenna crammed into a pepper shaker. They were designed for transit and public safety with TLMR systems in mind (many repeaters covering large areas) and are used in public safety alot. But those systems are designed for it. I run 2 Laird/MSI ghost antenna's on my work truck. One in UHF and one in 800. On a good day we can get about a mile Car-Car on UHF but that's on the highway. Get in the city and its less. For trail riding in a group its a good antenna as your talking to the guy in front or behind. If there is a good repeater in the area it works well. To be honest a 1/4 wave will out perform the ghost/transit antenna all day long and be just as durable as the ghost. I run the 1/4 wave on both my Jeeps and have yet to damage one or have issues talkign to folks on the trail.
  5. What radio are you using to hear the said tones ? I highly doubt a county would be on GMRS. What location is this ?
  6. The EVX is in the Motorola lineup so contact Motorola regarding software. I believe you can get a wideband entitlement key for that unit after a training.
  7. Just program both radios then have the shop re-tune the duplexer. The controller has dip switches for hang time and repeater enable. Here is the manual that has the dip switch stuff. No ID built in. We used an external COMM SPEC repeater panel on some so they could have MPL. This was not designed as a full blown repeater but really a small construction style unit to take from place to place. Basically to complete with the MSI GR300/500 series repeaters. https://www.icomamerica.com/en/downloads/DownloadDocument.aspx?Document=71
  8. The RT97 is ideal. Had one in my motorhome and would cover most camp grounds just fine with a decent antenna. The issue with the surecomm simplex repeaters is people understanding how they work and worse if they can hear both conversations. Save up and get the RT
  9. The baofengs are not good for scanning. Does it but not well. If you want a real scanner for a vehicle then there are many options from uniden and other scanner manufacturers.
  10. If its the true CY repeater yes. Sold many when I was at a radio shop. Basically 2 121 mobiles with a duplexer and custom controller in the box. Great low power repeater for home use.
  11. Send a message to Rich and he can fix it.
  12. Many part 95 certified radios. Just do some searching on the forums and you will find many of them.
  13. I can look tomorrow when i get home. Had some left.
  14. I guess the question is do you want a repeater that works or one that you can talk a mile from home with. That's the cost factor. All of my repeaters have at least $5000 into at minimum for hardline, antenna and repeater. All have 30-40 mile range. Can you do it cheaper yes but dont expect to talk all over with it. A good DB404 antenna will be $500 alone. Even my home GR500 (2 GM300 mobiles, rck and duplexer) was about $300 used. Thats a solid little repeater but then add the DB404 and 25' of 1/2" hardline, polyphasers and tripod mount on my roof and im well over $1500 and I can only get about 3 miles from home. Granted I'm not on a hill and the only reason for the one at home is to talk to my farm stuff.
  15. Already have them... https://www.garmin.com/en-US/p/702373 Uses MURS channels. Have seen them in many SXS already. Have not had a chance to order one yet but plan to for off road use.
  16. Sell it and buy one in the ham band ?
  17. I'd start with a cheap watt meter on a radio and feedline. As I say over and over thats the most important part of any system.
  18. Our first tower site for our SAR team was owned by a concrete company. You could almost not see the building with growth. We told them we would clean up the site, mow all year and help fix windows doors etc. We were there for 5 years until we moved to a county site. It was a great partnership and we left the place much better than it was. With that said we were a 501C3 with insurance. Without that it may be a stumbling block in these days.
  19. Also depends on the repeaters. I have 2 narrow band repeaters online. The 275 sounds great on them.
  20. All of mine work just fine. Have3 of them in 3 vehicles.
  21. They may control there own towers but thats it. I doubt they manager the public safety towers nor any of the commercial providers. With that said depending on location most of the commercial providers (american tower & crown castle) are going to require liability insurance as well as a hefty monthly fee for antenna at x feet up the tower. Your better off finding a private tower owner (not many) at a business or something that is no longer using his tower. In the NE there are many towers with UHF antenna's sitting on top for when they had SMR radios before cell. Alternatively a good piece of property and a 50' tower is not a hard thing to accomplish as long as there are no restrictions with the town/municipality involved.
  22. 6:" you should be good. I ran 2 UHF TLMR antennas in the back of my GC for years (total of 6 mounts on the roof). Never had Sirus/XM drop out nor issues with UHF
  23. Well all my fcc licenses are above line A and everyone has to have Canadian approval....takes well over a year to get a channel approved....
  24. Uh... 500' of LMR on uhf is about 15db of loss. You'd have about no power at the end. 3db is a cut in half of power. A good repeater will use good cable. I just optimized an antenna and repeaters this week that is 275 high. Cable is 1 5/8 with a loss of .445. Sweeps show 1.2db of loss. 50 watts leaving duplexes with 8.1 db of gain. Thats basically a 7db gain in the system. The difference between public safety and critical infrastructure like this vs a hobby is money. Very few on this site would pay the cost of parts let alone tower crews cranes and such.
  25. I laugh at commercials that like this....I leave my house and have no cell. I guess I don't have to worry about using too much data in my area...lol
