  1. 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
  2. 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.
  3. Good start here. https://wiki.w9cr.net/index.php/R56_-_Standards_and_Guidelines_for_Communication_Sites
  4. 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.
  5. 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
  6. 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.
  7. 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.
  8. 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
  9. 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.
  10. Not sure what you mean. There are only 5 MURS channels. Why spell them out ?
  11. 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
  12. I highly doubt the FCC will open up more GMRS frequencies for repeaters. Today its all about money to the FCC. They make millions on frequencies. But with all the griping about hams maybe we can petition the UHF Ham band to get moved to GMRS. It sounds to me many don't use it anyway.
  13. Garmin released the new Tread Off Road GPS with Ride Talk. It operates on MURS. https://www.garmin.com/en-US/p/702373/pn/010-02406-00 https://www8.garmin.com/manuals/webhelp/GUID-16B1D74D-857B-4FFB-8DE2-A0960FE0D090/EN-US/GUID-1C57D760-1BD2-46F6-B0CE-BC46503AEDBC.html Water resistance IEC 60529 IPX71 Operating temperature range From -20° to 55°C (from -4° to 131°F) Wireless frequencies (United States) From 151.82 to 154.6 MHz @ 31.7 dBm
  14. As reference Radio Reference is $30 a year. Others I belong to are $50 a year for download or limited access. Some sites use points systems to allow you to view or download certain items based on how many points. I think that's complicated. I think 2 levels would make things better with a basic package with no adds and maybe limited downloads to a premium package that lets you download other data (maybe base codeplugs, firmware, etc). I hate to say this as I run multiple sites also but it costs to do this stuff and most want everything for free.
  15. This is part of my issue. There are many 70cm channels to put a repeater on the air and chat or hold nets or what not. I agree ham is not for everyone and I get that. But I have yet to hear chatter on some repeaters between wife and kid or family member. Its normally 2 hams chatting about lunch or doctors etc. I have no issues with using repeaters but with only a few repeater pairs available it wont take long to clog up the airwaves. On top of the linking that every feels we need in GMRS its not going to be good for those that still want a base repeater to use with family. Landscapes change but its frustrating for those who have used the service for 2+ decades.
  16. a DB404 will work fine. I run a 404 on 3 of my repeaters. 2 are on tower sites 1000' higher than the surrounding area. 1 is on a 60' tower. I also run a DB408 as a receive antenna at one tower site with a DB404 for the transmit thru a combiner. The 408 and 420 are higher gain so if your way up may over shadow the area you are trying to cover. In the end all three are commercial made antennas used by Public Safety and LMR all over the US and are built to last.
  17. Front fender or rear tailgate is fine. If you search around I would say 90% use the front fender or hood with a lip mount. A few use the rear tailgate. Both of mine are on the front cowl mounts with my off road lights.
  18. Not commercially made. Are you looking for simplex or repeater use ? A RT97 repeater would be perfect for that situation however it would be used with you and your users only. If your looking to talk to other repeaters I'm not sure of a simple solution. Even once you can run coax 165' is going to require good cable and not LMR if you want any useable signal. In commercial applications a TRA on a radio is done so you run a 4WT cable to the base and hook it to the radio. Inside a Tone Remote would be used to transmit and receive from. They do have ethernet based remotes now but that isn't a hobby device pricewise.
  19. Thanks @marcspaz. I travel thru the metro DC area weekly (multiple days) yet never hear much chatter on GMRS. I scan the RPT channels in CSQ but never hear alot. Normally when I get over near Annapolis I'll pick up some guys but they are never clear so normally turn down the radio. I'll have to look into the repeaters and get them loaded in my APX with tones.
  20. Interesting you say this. I am a active ham and have been for over 25 years. I run multiple APRS digipeaters for SAR and personal use, as well as have multiple repeaters on the air. All are P25 but in the ham world. Additionally I help with another regional ham system that I'm not even able to use from home. Both myself and my wife have been hams for years. My issue with hams is very similar to @marcspaz brought up. I have removed repeaters for many of the common reasons, jammers, no use, no support. My main issue is 95% of the hams are just cheap. Spend $1500 on a HF rig but then complain their $29 CCR wont work on my P25 machine. I asked a simple question hoping to get some clarification.
  21. I know I am opening a can of worms but I'd really like to know a true answer on this. Why are there so many hams getting into GMRS vs staying on 440 ? More and more in my travels I hear ham chatter on GMRS. Yesterday I listened to a 30 minute conversation and about half way in realized it was on GMRS and not ham after turning my ham rig off and still hearing it. I don't get the lure to GMRS other than not having to follow certain rules ? I mean 440 had tons of repeaters pairs not used especially in rural America. If its truly because others in the family dont want to get a ham ticket ? I get that but rarely do I hear mom & dad or kid on the radio. Its always 2 or 3 hams (who sometimes give their ham call instead) babbling about this or that that happened on on xyz repeater or going to doctors or just nothing in general. I just find it odd.
  22. I would not set it to none on any XE radio. The entire reason its there is to have a certified battery on the radio. I ran into a customer who changed this on all the fire radios so they could use cheap batteries. A radio was sent in for water damage and was not repaired as it was using non IDLH accessories.
  23. FRS/GMRS without a doubt CH1 and CH2. Listening to hunters right now on CH2. For repeaters I have them on 600,625,675. Some of my locations are above line A so cannot use 462.650 MHZ, 462.700 and 467.700. I used to have on on 550 but too many folks programmed the radio on the input and would use it to talk simplex.
  24. A scanner is a better way to listen to other frequencies other than GMRS. I have one bank dedicated to GMRS on my scanner.
