GMRS Callsign

Ham Callsign

  1. 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?
  2. 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?
  3. 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
  4. 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.
  5. 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.
  6. 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
  7. 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.

  8. Please advise: What is the proper procedure for one licensed GMRS user to call another when both have licenses? In other words, I am new, what is the proper way to call another licensed user? Do I say xxxx123 to xxxx321, Michael to John, or radio check? What is the proper procedure to call a known person, or an unknown person, i.e. "Hey, is anyone using this frequency?" Please don't respond with jargon or abbreviations, I am new and have no idea what a "travel tone, PL, off-set," or any of the other terms bantered about are on this site... hopefully, I'll learn them shortly, but for example, I'm trying to connect up to the Ft Lauderdale, FL Repeater... I can hear it (sometimes), sometimes I hear morse, but can't seem to activate it as I can't hear it back on another HT (I just learned that term!) So, what's the way I should "call" to see if anyone can hear me?
  9. Hi I'm new here, I recently received my GMRS license and purchased a pair of Midland FRS 2 way radios. In the near future, I would like to get a MicroMobile GMRS unit. I understand that I am able to communicate with FRS on certain channels. What I am wondering is, am I allowed to use FRS radio in conjuction with the MicroMobile unit in the same room or vehicle, since I have a GMRS license? WRHW452
  10. Hi, I have 3 radios for sale: 1- M120 $30+shipping 2- M1225 $45+shipping (each) All programmed for GMRS freq's. All have a mounting bracket and mic. All working, change out due to needing more channels for multiple repeaters Freq list with each radio. Stephen Willis scwillis@hotmail dot com
  11. Hello all, I'm fairly new to the radio world even though you'd think my USMC Infantry background along with my current Firefighting gig would lead you to believe different. I should've paid closer attention obviously. I recently purchased a pair of Motorola MS350R GMRS/FRS radios. Wasn't even aware of the features or what the capabilities where until thumbing through the user manual. After some time on Google, I applied for and was granted a GMRS license from the FCC. I have spent the past couple of days trying to get these things to work on the repeater function with no luck. I'm a little ways from the nearest repeater but, I don't receive anything. Not even broken communication. I don't believe these things to be digital so I'm under the impression that I should still get garbage as a conformation. But to dive even deeper on the subject, I do not even know what I'm doing. I have no understanding of the freqs, or how to set the radio up in the first place. Everything I can find online is already a step above my understanding. Other than looking at what the channel freqs are and trying to match them (kinda), I have no idea of what's what. I DO know what channels are FRS, FRS/GMRS, and repeated GMRS. Also would like some clarity on the FRS/GMRS channels if you wouldn't mind. Any help will do. All I ask is that you assume I know nothing. Your wisecracks and jokes are encouraged as long as learning is achieved. Thanks in advance, K. Brown
  12. Hello everyone, I have a new guy problem. I am using a Tera tr-505 to transmit to a Midland base camp xt511. I can't get the 505 to transmit until the base camp transmits first. When I transmit with the 505 there is a hum on the base camp and thats it. If I hit the push to talk on the base camp then my 505 can transmit to the base camp no problem. I odd thing, if I turn both radios off then on the 505 will transmit to the base camp, once I change channels no go. I must have touched a setting or something simple. If anyone can steer me in the right direction that would be great. Thanks.
  13. 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....
  14. We have a 40w Motorola repeater and I've got an ANLI-100 antenna about 15' over the house, connected with 50' of LMR400 cable. It's on a metal roof, the house is at about 3000' ASL. In the immediate valley, pretty much with 'line of sight' - but with dense foliage, they're around 2200'. I haven't measured SWR, do not have a SWR meter, but I think it should be close enough to work even considering the line loss and slightly out-of-band from ham dual band VHF/UHF antenna. When I first got repeater, in the winter time, without leaves on most trees, It worked well and as expected. I could go about 4-5 miles away... Now, in the summer, with very dense foliage, I can hardly make it a few hundred feet away! There is both a very steep elevation change, as this location is in mountainous area, and very very dense foliage. In my research, it seems that a "circular polarized omnidirectional" antenna has been tested and used successfully by Motorola - a long time ago - with use in UHF frequencies. I'm looking to see if anyone has experience building an antenna like one of these "cycloid dipole" antennas for the GMRS frequencies? https://ka7oei.blogspot.com/2013/08/a-circularly-polarized-omnidirectional.html http://www.wa7x.com/cycloid_info.html Anyone have helpful thoughts on if this would improve reception for me, in the foliage?
  15. To all GMRS licensees: I have just spoken with the FCC regarding a Petition for Reconsideration filed by Motorola regarding automatic GPS and data transmissions on the GMRS band. Motorola would like to allow automatic transmissions on the 462 MHz frequencies which includes repeater outputs (Channel 15-22) and the interstitial 462 MHz channels (Channels 1-7). The repeater inputs are not presently mentioned, however we will articulate our position to the Commission that these input frequencies should be prohibited due to the potential of interference to repeaters. myGMRS.com (and it's parent company RepeaterFinder, LLC) will be filing an ex parte response in the docket with the following requests: A Busy Channel Lockout (BCL) feature be mandated for any radios which are to operate in an automatic fashion. The devices must inhibit transmission if there is co-channel activity to prevent interference to other users of the shared frequencies. Blind periodic transmissions are going to be very problematic and will almost certainly cause interference. Limit automatic transmission to the 462 MHz GMRS channels only. Repeater inputs must be excluded to mitigate potential interference. Duty cycle limits of the bursts must be set by the FCC. I believe Uniden America proposed no more than once every 2 minutes and no more than 5 seconds per transmission. This sounds reasonable to cover longer text messages and location updates without constantly trashing the band. The FCC plans to respond to Motorola and issue a decision in the next couple of weeks, so anyone who would like to submit comments to the record is encouraged to do so as soon as possible. No exact deadline was given, but they expressed a desire to have this hammered out within the next week or two. I will provide further details later today.

  17. How to apply for a GMRS license and receive your FCC call sign Here is a step by step guide on how to obtain a GMRS license and call sign from the FCC. I originally posted this on my blog, but I want to share all the same content here for future reference for any members, guests, and visitors to myGMRS.com. To obtain a GMRS license, one must file an application with the FCC and pay a $70 fee. No exam is required, and the license is valid for 10 years. The FCC’s Universal Licensing System (ULS) is is an online portal to manage your FCC applications/licenses, and pay any applicable fees via a single account. The ULS eliminates the need for paper applications and submitting via snail mail. You may also view the status of pending licenses in the ULS. Once registered with the ULS, you will receive an FCC Registration Number (FRN). This is a 10-digit number that is assigned to a business or individual registering with the FCC, and is used to identify the registrant’s business dealings with the FCC. Once you have this ID number – save it! This will be your username to log in to the Universal Licensing System. Before continuing, I want to highlight one very important consideration when dealing with FCC licenses. Your call sign and license is public information and is easily searchable in FCC databases and other records. Should you choose to register with your home address, this will be visible to anybody if they have your call sign. Exposing personal information on the internet is a concern now more than ever, so one approach to limiting the amount of personal information in FCC databases is to use a P.O. Box as your contact address. Here is what my GMRS license information looks like when queried in the FCC database - WRAA720: I use this P.O. Box address in the center of my local metro area as my primary contact location for all FCC forms and dealings. My actual home address is not associated with my FCC licenses. Step 1: Create an FCC Universal Licensing System account If you are a first time user, create a new ULS account here (skip this step if you have an existing ULS account). Select “Register” to be issued a new FCC Registration Number: Some questions are asked before proceeding, then you can fill out an application with your name, address, password, etc: Step 2: Log in to the ULS After creating the account, or if you have an existing ULS account, log in here. Use your existing FCC Registration Number (FRN), or the FRN provided after completing the first step. Once you are logged in, you will be taken to this screen which shows your current and applied for licenses: Step 3: Begin application for a GMRS license Now we can apply for a GMRS license and pay the fee. On the left hand side menu click “Apply for a New License.” On the next screen, select “ZA-General Mobile Radio Service” from the very bottom of the drop down menu and click Continue. The next step is to answer these applicant questions. Most people can leave “no” selected for each: Click continue after these questions, and on the next screen supply the licensee name and address: - Part 2 continued below as there is a limit to the number of images in a post -
  18. I came across the North Shore Emergency Association's website recently and found their club history page interesting: nsea.com/nseainfo.htm This link briefly discusses how the "travel tone" of 141.3 Hz and the national calling/emergency frequency of 462.675 MHz came to be. NSEA was one of the very first adopters of GMRS in the early 1970s, then the Class "A" Citizens Band. Here's a quick snippet from the link: NSEA members were instrumental in bringing UHF technology to other public service groups in CB, especially R.E.A.C.T. (Radio Emergency Associated Citizens Teams). Beginning in 1976 key NSEA members spent extensive time meeting with REACT teams in more than a dozen-and-a-half different states, bringing a portable repeater, together with a number of mobile and portable units for field demonstrations...As a result, over 200 personal use repeater systems (all on the same frequency [462.675 MHz]) were set up throughout the United States. In recognition of this trend of explosive growth the Federal Communications Commission formally recognized our frequency [462.675 MHz] as the national emergency and traveler's assistance channel in the Part 95A Rules and Regulations. Pretty cool slice of radio history!
  19. I just posted my Motorola repeater for sale on eBay. The auction ends 5:38PM (Pacific), 4/16. I used it as a repeater with my GMRS walkie talkies (Motorola MS350R). The auction includes the repeater, microphone, two antennas, coax cable, and programming software and cable. The unit is programmed to work with 8 GMRS channels and two privacy codes (see the auction page for the details). You can my find my ad by searching eBay for item: 132575810225. If you have any questions, please contact me via eBay. Thanks. Michael.
  20. ok. So from what I can tell by reading some of the discussions on here, the uv-5r is not part 95 for HT even though i have a gmrs license? does this still stand if I use it as a base radio? I'm still green on these things so please be patient with me. I'm am trying to learn and understand so I can pass the right info to my family and friends. I have read through the part 95 rules but still a little confused. Basically I need layman terms.
  21. I’m new to the forum and am curious to know if there are any other users in the greater Charlotte, NC metro area. I live about 35 miles southeast of downtown Charlotte, near the NC/SC line and US–601. I’ve had my GMRS license for a bit, but have yet to actually talk to anyone. I have a Wouxun UV-3D handheld and 2 Motorola CDM–1550 UHF mobiles that came without power cables or microphones (what did I really expect for that price on eBay, LOL). I’m just wondering if there is any local activity. I’ve been a licensed ham for 21 years and I know there is quite a bit of local VHF usage there. Thanks in advance and have a great day! —Matt R.

  22. OK, central Florida checking in here, and I do mean central. We are post hurricane Irma, and all utility services are up and running. We do have a lot of debris piles on the road side. The eye of Irma essentially passed over Polk County. My friends at T-Mobile seriously disappointed us by what seemed to be a severe reduction in service quality in town prior to any winds near tropical strength starting early in the late afternoon. For several days after the storm, there was little to no signal, and 8 days later there was still poor coverage south of us. I understand antenna and tower damage... My Irma experience urged me toward handheld radio. I grabbed a license from the FCC and made a purchase. Now, I wasn't expecting miracles, and I certainly didn't expect the 50 miles advertised on the package. But, I am still disappointed. I finally caught time to test the radios this afternoon. We were on the radios' channel 20 which is 462.675 MHz (GMRS 13). We were on the highest power setting and used the boost feature. My goal was to reach a nature preserve at a distance of about 5.8 miles. The greatest distance that we could hear each other was about 1.8 miles. See the attached JPG. Again, I didn't expect 50 miles or even 10 miles. But, 1.8 miles seems extremely short to me. I seem to remember at least 10 miles on my dad's CB radio in his VW van sitting in our front yard back in the mid 70s. Am I being unrealistic to expect more from the Uniden 5095? What would be a realistic (Not Realistic - Get it? LOL) replacement that would give me 5 - 10 miles range. It would have to comply with my GMRS license, and I am willing to license up to amateur levels. Thanks in advance.
  23. "Petitions for reconsideration" are due within 30 days of the rules being published in the Federal Register. The publication is expected for late June, maybe July.
  24. Hi All - I am fairly new to GMRS. I've worked in a shop and have done minor tuning, programming, installs and surface mount repairs on portables and mobiles over the years. I have limited experience with repeaters. I am attempting to setup a home repeater in Dutchess County, New York. Equipment I have: 2 CDM1250 UHF Radios (40 Tx Watts / 25 Rx) 1 Dual power supply 1 ID O Matic 4 IV controller 1 Duplexer (properly tuned to Hi and Lo) Can somebody make recommendations on the remaining equipment? (10 foot coax run....type of cable...N connectors.....antenna). I can not get onto the roof, so I will be running a pole/pvc out of the highest window of the house....extending it to roof level. Thank you for your help! Brandon, WQYZ962
  25. Needing a little help with a new GMRS radio and use of a local repeater. I am in Greenville, SC. Licensed GMRS "WQNF353" for several years, but really never used GMRS frequencies. Interested in setting up so I can speak and work with several friends using a network around Greenville. AM aware of a local repeater which is set to transmit on 462.725 and the repeater recieves on an offset of 5 megahz . I don't know if a tone is required and need help figuring out if and how to use. Using a Baofeng UV-5x3 and have the radio set to send and recieve using the offset. The local repeater is owner is ZULU725 and I need to know how to get in touch with owner off frequency. Have attempted a call to his sign but thinking I might be needign a "tone" to set his repeater to "ON" Any helpful ideas are appreciated.
