GMRS Callsign


Ham Callsign

  1. Hi just wanted to introduce myself. i'm new to gmrs, and have already learned some things involving it. i have been looking over the forum here, lots of good stuff. i have tried to reach out to see if any one is out there on the air, but like most of the ham repeaters, no one is about, and most of the repeaters are no longer up and running. i am also a ham operator, and enjoy the occasional rtty contest. i have a tk-860 on order, and i should have most everything i need for mobile gmrs by the end of next week. anyways....
  2. Hello Internet! It has been awhile since I've been playing around in GMRS and I have learned a lot of things over the past few months. I believe I am finally ready to try and create a repeater of my own. My location is favorable as im on top of a hill that oversees the township so I want to give it a go. The ideal use of the repeater is to provide a method of local communication within the township. Im located near and in range of the CSRA Columbia network, but I want something small and local, plus its just a fun project to try and accomplish. I have developed a rough plan and got some equipment I have looked at and will start collecting soon based on how this thread goes. So far I have got 2 Motorola GM300 UHF radios as they were fairly cheap and work well with the repeater interface I got for it. I plan to run theses radios at 25 Watt output. For the repeater interface I chose a Motorola HLN3333B R.I.C.K. as its just plug and play with the GM300's plus it adds the option of remotely shutting down the repeater via DTMF if I desire. I already have covered a power supply so that's good there. I want to get a duplexer and this one offered on MyGMRS looks good but I want some opinions about it from folk who know a bit more first before committing on buying it. If there are other duplexers out there that I should consider, let me know. The antenna I have planned to get is a Tram 1486, also offered by MyGMRS as a option and i'll have this mounted straight above the set up which is inside of the shop. From floor to antenna base, about how tall should I mount the antenna? And for coax, I am leaning towards using 100ft of LMR400 coax cabling. I herd it would get the job done well and its not too expensive. So far that is everything I have on the list. I'll worry about building antenna mounts and a cabinet for the radios later. I know i'm not making something that is perfect and i'm not trying to cover an entire county, but I want something that works well for a starter and to go from there. Im hoping to achieve about 20~ miles and I hope im making the right decisions with some of the equipment I have and plan to get. Let me know what you experts think and help guide me in the right direction. Looking forward to learning more!
  3. I was inquiring on if anyone has a quick spreadsheet on all parts required to get a repeater going for gmrs. Rough estimate on all equipment, parts required...I have also been reading that the KG-100g is repeater capable with another same type radio. Is anyone tried this and what were your results and range with it if so.

    Lineup of my current GMRS radios. Newest addition is the XPR7550e on the far right. That was just purchased recently, and is being programmed for use on local repeaters and simplex freqs. HT-1250's like the one on the left are still very useful for this purpose as well. Starting left to right: Motorola HT1250, Garmin Rino 530, Anytone UV-878D, Motorola XPR6550, Motorola XTS1500 M1.5, Motorola XPR7550e.

    Laird 450 to 470 MHz antenna, and magnet mount New Motorola style base, with mini-UHF antenna connector. Great combination for Motorola mobile radios and GMRS use. 450-470 MHz antennas have their sweet spot right where GMRS frequencies lie.

    Motorola UHF commercial band 470-512 MHz EX600XLS handheld, Garmin Rino 530 GPS/radio, and Motorola XPR7550e UHF 403-523MHz handhelds, on top of a Panasonic CF-53 used to program the Motorola radios. In front of a cheap Lenovo running SDR# (SDR Sharp) software, showing the waterfall for Channel 4 FRS, and where I keyed up the Garmin Rino a few seconds before taking the picture. SDR# is handy for watching swaths of RF spectrum to see what is going on in range of the RTL USB SDR stick and antenna.

    2004 Pontiac Grand Prix with antennas on the rear window and trunk lip. Rear window was the factory On-Star antenna, which was removed once that service was no longer free.....left the nub of the mount though. Going right to left on the trunk lip, a small XM satellite antenna is shown, then a NMO (New Motorola) trunk lip mount with Laird UHF Phantom antenna for commercial UHF/GMRS use. Phantom antenna was connected to a UHF Vertex VX-3200 mobile. Last is a NMO VHF whisker style antenna, connected to another Vertex VX-3200 mobile. The VHF I started with was a Sti-Co, but someone must have noticed what it was and took it at one point. I then began to use cheap 5/8 wave VHF antennas bought in bulk from Tessco that were never stolen. I found this interesting as the UHF Phantom style antenna was the most expensive, but looked cheap and ineffective.

    Radios used in hiking throughout the recent snow storm in the Pacific Northwest. On the left is a Radioddity GM-30 radio that is the most recently purchased unit. For Chinese radios, I prefer the Anytone AT-D878UV, but the GM-30 is one fifth the price. Next is some older Motorola TalkAbout, possibly a 62xx series, but it does not say, so it may be newer vintage. On the right is my old Garmin Rino 530, pre-SD card version. All three worked well in temperatures hovering around 25 degrees Fahrenheit, and over distances of about a mile apart.

    My "listening post" for my recent trip to the forest. Went into the Olympic National Forest to get away from it all, to include cell phone and radio station signals. But, I still took some gear to hear what was available. One weather channel was noted on the Garmin Rino 530 when scanning weather channels. Channel 4 FRS was also noticed, in use by what sounded like a family unloading luggage at one of the nearby lake resorts. This is the original Garmin Rino 530, that does not have mini SD card capability, and I bought after being issued and using a Garmin Rino 120 while on military deployments to Afghanistan. The 530 has a color display, which does not work too well with image intensifying night vision, where the monochrome 120 does much better. As radios, they work as well as low power UHF can be expected, and being able to send location was helpful at times. The Rino 120 was issued to many military personnel as a sort of intra-team radio that also had a basemap, something the military issued AN/PSM-11 Rockwell units lacked (the newer GPS now has a map display). The Rino 120's acted as a backup measure for areas where accurate maps were often only found in old National Geographic magazines, while the radio worked well for short range (intra-team) comms. (Most of us were also issued Harris AN/PRC-117F portable radios and Thales AN/PRC-148 MBITR's as well). I still use my Rino 120 and 530 as they still work, and are very helpful running around the woods. The GP-7/SSB receiver picked up about a dozen FM and six AM frequencies but none were local. While driving around, there was a piece of cardboard near a house with what looked like an amateur antenna, and a frequency listed. It turned out to be low power radio sending music around the nearby area, about three miles or so away.

    RoIP rack with VHF commercial, VHF Marine, and UHF commercial radio frequency programming, for use with Telex/Bosch Communications IP-223 IP interface devices. This allowed computers running Telex C-Soft software to remote control the radios via an Internet connection. This rack ended up in an emergency communications package, installed within a conex box, which was then sent to hurricane/oil spill/and exercise response efforts. The UHF equipment was capable of being programmed for GMRS and interoperable comms with local auxiliary communications services spread around the country to assist first responders. However, all of this is analog, and was used near waterways, hence the marine radios. All of this has been replaced with newer gear, or decommissioned as smaller palletized systems took over.

  14. Hello! First post on any forum and recently got my GMRS license too, So needless to say I'm excited to get out there! I have gotten a Kenwood radio for myself to adventure in GMRS thanks to this forum and it's been a good little unit. Now just a few days ago I was out at my states surplus sale where they sell old desktop pcs, furniture, cars ect. Well they had a Motorola APX7000 on the shelf with no battery, antenna or anything, and I bought it on its circulation sale for $500. Before I go crazy and get a battery, charger, antenna and have programmed by someone, I would like to ask if it would be a radio I can use on GMRS and repeaters. I know this kind of question gets asked a lot and I'd hate to add to that annoyance but I've done the better part of my do diligence in research but I'm still left asking. It doesn't have a front display or keypad for FPP, just the top screen like my Kenwood. I've tried to find any forum posts relating to APX on GMRS here and on other websites but I've come up short. It operates on UHF in the lower band, 380-470mhz. I mainly got it because of the price and if I can use it, then great! If not, then I can try to sell it for a profit. Win win for me. If I need to give more details then I can try my best to, otherwise let me know!
  15. I have two handheld that will not be used as individually transceivers and thought it will be unique to use them as the basis for a GMRS repeater. I know how to set up channels for repeaters on handhelds. but, how would I go about building the repeater and what should i expect?
  16. I have a few HT's and local repeaters that I have access to. I'm toying with the idea of setting up my own repeater at my house mainly because it would be "mine" and for the educational purpose. I'm wondering what's the cheapest way to get a repeater up and running at my home? My thought would be I could put an antenna (or 2) in my attic - I could put them outside on a lower roof but I don't think I can ground it adequately (hence the reason for just putting it in the attic), the actual repeater being two base units running a max of 50w. Is there any RF exposure issue to be concerned with at GMRS freq's at 50w? Now I live in an urban area where there are hills, not mountains and simplex to simplex with a KG-805 can get about a mile or two - two if I'm outside. I don't have the ability to erect a large antenna tower...and in reality even if I mounted an antenna outside on the highest point of the roof I couldn't get above the tree line - that's at least another 20-30 feet above the roof of my 2story house. Thoughts - is the cost to do this coupled with the expected performance going to outweigh the learning/fun aspect?
  17. Greetings all, There are two AM Radio broadcast (talk radio) stations in my area. One uses three commercial towers and the other uses one, not that the number of towers matters.........or does it ? In my attempt to place a GMRS repeater on the air it has become painfully obvious that I am not able to achieve the antenna height needed to render this repeater to be of much use to most people, including myself, since the maximum range in all directions is just over 7 miles using a 25-30 watt mobile approximately 3.5 miles for handheld use. I noticed that none of the towers that the AM radio stations have, have any (that I can see) antennas mounted to them and remembered learning somewhere, that AM Radio transmitters use the tower structure as the antenna so with that in mind, it’s understandable not seeing other antennas on the tower. But, that got me thinking....... I remember years ago on the opposite side of the county the local AM (country music) radio station and the State Highway Patrol (using VHF) shared a tower and it worked quite well for both parties except for the last 5-10 years. During the end of this setup, every time the Highway Patrol dispatcher would transmit, the music from the radio station would also come across but was at very low levels sort of like “background” (no pun intended) music so you could still hear the dispatcher with no issues. I’m guessing this could have been mitigated with either filters or some form of adjustment but wasn’t since the State was in the process of switching to an 800 trunked system. So, now that I’ve written a short story........... This answer might be obvious to some but as I’m still learning, I could use some help. Can a GMRS/UHF repeater antenna be mounted on an AM radio tower without causing problems for both users? Is there additional equipment needed for either party, other than what’s already in place for the radio station and for the repeater side, the repeater with duplexer, feed line and proper grounding ? I look forward to the always helpful and friendly advice and guidance I continue to receive from the members. J
  18. I have a Wouxun KG-UV8D+ and I'm using CHIRP or the Wouxun software to program it. I just can't seem to get it right. The repeater is 462.6000 - Out PL 110.9 - In DPL 712 What I need to know is what gets entered into each column in CHIRP. I don't understand the column abbreviations.
  19. I've had my gmrs mobile radio a little over two weeks and my license about the same amount of time.. I have only been listening, so far and honestly have learned some cool stuff. I was on channel 18 on my tiny frs handheld and stumbled onto a regularly scheduled net every Wednesday @ 19:30. I have a lot to learn but these guys on the Technical Net (frq. 146.820 K7LED) were clearly HAM operators not using a gmrs repeater but talking all things gmrs. I would one day like to be a part of those kinds of discussions. I am in the Seattle and it looks like gmrs repeaters are not that abundant. Do any of you participate in net repeater discussions on gmrs repeaters in your areas? I've also started to detect a bit of arrogance in the HAM community towards gmrs. Still trying to find my niche. Comments? Thoughts? WRMH268.
  20. Hi Folks, By way of introduction, my name is JT (WRKZ907) from Great Neck, Long Island, N.Y. I'm a newbie to this hobby and just recently purchased a Radioddity GM-30 GMRS Radio, while awaiting delivery of my Wouxun KG-905G's to arrive. I figured I'd get my feet wet learning how to use the GM-30, which seems to have a rich set of features, one in particular I would have liked to have seen on the KG-905G, which is the NOAA monitoring. Anyway - as I stated, I'm totally new to this, and I'm doing my best to ramp up to speed on my own, but I find interacting with others has always been a great way for me to learn things, and in particular - trying to understand how to program the tones for repeaters with the Radioddity GM-30, both manually and/or via the software for the device. Don't know if anyone out there in myGMRS last would be willing to help mentor this newbie & provide some assistance in helping me come up to speed and understand how this repeater stuff works, and would be willing to spend a little time with me, ideally someone in the Queens/Nassau area would be great, so we could possibly communicate together on air, but I'm happy to accept any assistance from you fine folks if your available & willing. Thanks in advance for any input or resources you folks can point me to or provide. I've already received some kind assistance from the friendly folks on the forums, & look forward to one day being able to return the courtesy to new members as well. Kindly, `JTL WRKZ907
  21. Hello folks, Some of you might be interested in our video series on deploying our club's GMRS repeater to our main repeater site. We are also currently in another video series where we are building a GMRS repeater to deploy at our secondary site. We do have several other Amateur radio frequency repeaters in service but GMRS is still an important service for us all to use and to provide to our community.
