  1. Well that's your issue. You need a true base station antenna and feedline if you expect more than a couple miles. A laird FG4503 or 4507 would be ideal with some good feedline.
  2. So the xtl2500 is an good radio. I would not use them for a repeater as you can sell one and get 3 or 4 CDMs or M1225 for the price...but... Your going to need to use J2. Also be advised some versions of that radio had an active high and not active low for the COR pin. Nothing is programmable on J2 and its fixed. Pins are still available online. As said you need a duplexer and a controller of some sort.
  3. I have P25, DMR and Fushion. I really only use P25 for simplex and repeater use. Basically use it all day every day. The only Fusion stuff I have is my APRS radios in my jeeps and a handheld but really the radio sits on 144.390 for APRS and 146.520 and rarely is changed. DMR I have a few handhelds, hotspots and a mobile but have no interest. P25 is so much cleaner and quiet for what I use RF for. Other than the Fushion/Yaseu all my gear is Motorola and mostly all APX with some XTL/XTS splattered in if needed.
  4. How long is the cable to the antenna ? What is a small gmrs antenna ?
  5. What code ? The one that expired almost 3 years ago ?
  6. Barbour county uses the SIRN System. Either buy a scanner to listen or use your phone. The conventional fire dispatch channel may be heard but remember you have a crappy UHF antenna on a CCR not a VHF specific radio.
  7. Duplexer ? Antenna ? Feedline ? There is alot more than plugging a cable in and saying you have a repeater. How far away are they ?
  8. 100% accurate. I've been on multiple Jeep Jamboree's and I can say most don't know they need a license, nor care. The radio comes out of the box and works.
  9. Ive wondered the same over the years. Hopefully Rich can clarify.
  10. If its unlisted then send him a message. I asked if you were logged in as many dont and if not logged in tones are not visable.
  11. Well in the LMR world we find the needs of the client, then run propagation studies to meet the expectations of the customer and meet the license requirements. In the past I did many warehouses that had a 10 watt UHF repeater in them with hundreds of 4 watt portables. I have also put in multiple GMRS/SAR/Public Safety systems that covered many miles and counties. All designed and engineered before install. In the hobby world I try to do what I can and learn from mistakes of others. Spending a bit more money on a decent antenna normally is worth its weight in gold. Wind, Snow, Ice change the antenna some will use. Since moving south I dont worry so much about ice load on my antenna, but wind is still there. Also what can the structure handle for weight and loads. Wind loading is a thing. The Laird antenna is a great starter antenna. I use them for control stations, low power repeaters and temporary installs. The DB404 is a bullet proof antenna but weighs twice the Laird. But I have DB antennas on towers for 20+ years with no issues. Can't say that about my Lairds.
  12. Are the tones listed on the main page under the repeater ? IF not then reply to the message and ask for the tones. Remember you must be logged inot the main page to see tones.
  13. LMR240 for 25' would be suitable. At 100' you need LMR400. I have a VHF Search and Rescue Repeater. I swept the cables. We use LMR400 for 30' jumper and when we use the 60' its 1/2" LDF. Yup its bulky but it works well. Remember at 100' thats just about 3 db (2.7) of loss. Thats half the power you put in and 3db receive less. 240 is 5db of loss at 100. I wouldn't even consider it.
  14. There a ton listed on the map. Go and see whats in your area. Personally I've never had success in any of them. https://mygmrs.com/map
  15. 1
  16. I've alwasy been a garmin fan. Have a ton of their stuff also. I think the MURS is actually good for riders. Your going to get further than FRS and its used less than FRS right now. I added one to my wish list for the Jeeps.
  17. Good start here. https://wiki.w9cr.net/index.php/R56_-_Standards_and_Guidelines_for_Communication_Sites
  18. RT97, 6' LDF and a DB404 is an ideal setup for a silo. Just run 110' (which is normally already up there) and plug it in.
  19. Why is this the case. Repeaters have been permitted since its inception. Ham radio has repeaters and many at that that never get used. The more I think about it maybe I'll just throw a 70cm repeater on the air and use P25 to keep it quiet
  20. Ya most of them did not come with this PS. The standard one in the GR500 case is to be honest the better one. This is what the revert kit looks like. It would of been added after and you would not use the screw terminals on the outside for it. http://www.repeater-builder.com/motorola/r1225/pix/hln9455a-battery-revert-kit.jpg Also it will take forever to charge a dead battery. If you do run on battery for any length of time I would pull the battery and put it on a good charger to verify. Short power outages are fine but if it goes until the battery is dead and repeater shuts down use a good charger. Also always fuse the battery cable as close to the battery as you can.
  21. The slick part about it is it does use a external antenna connection. It talks about installing the external antenna. The rubber duck would probably work in one mile but I think a standard VHF quarter wave on a NMO mount would double its performance. It appears to be an SMA connection but they don't specify. I'm trying to decide if I'll order one or not. I just replaced my overlander in the Jeep but adding MURS in the same unit and not worry about another radio seems slick.
  22. How about just order it from Motorola. Shows in stock online. Not sure who you called but its not discontinued. https://shop.motorolasolutions.com/dual-tone-multi-frequency-microphone/product/AAG22X501?gclid=Cj0KCQiAtvSdBhD0ARIsAPf8oNnoEOx1A42kkF7yOiEoC_Bx3JhegPOmuDGI22zXsNj0-gbzzAR5bAYaAk1YEALw_wcB
  23. I agree, but that was one of the comments in the thread about 70cm not being used....repeaters that sit with no one on them. Maybe it would at least encourage them to use what they have.
  24. Not sure what you mean. There are only 5 MURS channels. Why spell them out ?
  25. Does it have the battery revert board in it ? Most did not ship with it. The standard power supply in the GR500 does not have the output needed to give the Active low to the repeater. If you have the proper battery revert PS below has the info on soldering to the board to get the 3 wires you will need. Page 7 of the manual below. http://batlabs.com/gr400.html http://www.repeater-builder.com/motorola/r1225/pix/hln9455a-battery-revert-kit.jpg http://www.repeater-builder.com/motorola/r1225/r1225-overview.html http://www.repeater-builder.com/motorola/pdfs/hln9455-battery-revert-accessory.pdf
