"If a repeater is not identifying but carrying traffic from multiple authorized licensees, the repeater owner is at fault." Not true, the users must each individually identify, but the repeater does not need to, or it indicates the traffic is from the owner, and not the authorized licensees.

Same as FB4 in part 90. (Community Repeater) each individual or business had their own license and the owner had one that included the repeater. If you are going through someone else's repeater, it is your responsibility to operate your equipment according to the rules. If there is a technical problem with the repeater equipment itself it would be determined by the person monitoring it. Once you monitor several different users through the repeater it is fairly easy to discern where the issue is. It is always the user's responsibility to give call sign. The repeater operator usually doesn't chose to let the repeater ID itself (like with a controller) unless he is the only user.

I've heard that alot. Nothing to prevent it, they can use FRS, however, any legit business should get an assigned frequency and license in part 90. Most of the time, it's just a business taking the cheap way out. There was an industrial supplier near me that finally got off FRS due to people breaking the cheap radios, and the fact they were on channel 1 code 1...genius...and always had "interference". LOL Added: I also ran into a situation with a Highway Dept that has a VHF repeater and good radios (Narrowband VHF), but in their flagging operations the radios were setup for 2 watts to conserve battery, and being narrow, range was crap. In fact, they could not hear each other even though they could see each other sometimes. One of the guys brought in his kids FRS radios and they could actually hear each other. I told them to tell their boss to buy a couple of Trbo radios for flagging and program them for 5 watts, and they can still have the main repeater channel in there too.

I have a couple of TRAM antenna mounts left over from a project I did. One is a Stainless Truck Mirror Mount, which can also be used as a bolt on bracket type (Tool box, Rack, ATV, etc). Mini Uhf Connector, NMO Mount. $36. And Two (2) of the small mag mounts. Mini UHF Connector, NMO Mount. $26. All new in package. Paypal for payment. Shipping to 48 CONUS included in price. Thanks.

I can echo that I have both personal and professional experience with both, and always prefer the NMO over a Mag. Why? I always saw a Mag as a temporary setup. Over time they can have issues, mostly from water. I have even seen the ones with clear plastic seals on the bottom have water in them. I observed that reflected power was always better with NMO, and the lower the frequency, the worse it got on the Mag. When I was working at the M shop years ago, our local Sheriff's dept would keep a couple dash mount D51 Maxtrac lowband mobiles, cig plug power cords and Mags for winter, so they could "borrow" a couple of 4x4 Ford Broncos in case of big snow events. Then they would spend 2 hours at out shop while we tried to explain why they were not working right with 60 watts out and 25 reflected at 39 Mhz, and find a sweet spot on the roof where the reflected was better. The older techs told me 26+ years ago that a 1/4 wave on a NMO was the best, most reliable antenna. I found that out several times over the years and that is all I use today.

PL/DPL is for channel sharing. It is not for privacy, and is not for interference, as interference would mean you have exclusive use of a channel. Even in commercial use, it is for filtering out unwanted co-channel users, or distant "skip" signals. As said above, a radio in CSQ hears everything. A radio set to a PL only hears transmissions coded with same PL.

I don't climb...I always thought about buying old worn out bucket truck to use as my "tower"...lol.

The answer to the original question is simply, NO. Without regard to power or whether it is mobile, handheld, or fixed....it is not acceptable to transmit on the repeater input channels (high side) in GMRS unless you are talking to a repeater.

It is a new one in original box. Complete with new mic, power cable and bracket. *** SOLD *** Moderator: You may remove at will if doing clean up. Thanks.

Looks like a few repeaters in the area, get permission and start monitoring, announce you are on air. Power cables and Mics for 1550's are easy to find...good radios, use them!

1. Iv'e never seen anyone "grab" a license from the FCC. 2. The reason we get disappointed in the first place is THAT we have expectations. 3. I'll quit dinging you for looking like you just took a creative writing course and got a C+. Seriously - no, those radios are no going to have "real" range, I don't care what the box says. I assume that my (4) little Uniden GMR1048 with the "forbodden" scramblers are good for a mile. If I get more, Ok, but I use them to that end. When it's time to COMMUNICATE I use real Motorola radios, handheld or mobile, via or sans repeater. Not everyone wants to go that far, but I used to work in commercial radio, so I do. Step up to a wideband, 4-5 watt (commercial or pseudo commercial) radio with a good antenna and you will do better. Any obstacles including buildings you are in or thick trees will cost you 3-6dB (50-75%) loss. keep that in mind. I got a B- in creative writing. So there.

It's amazing how many idiots live among us. I think some of it is truly the mentality that "if I paid for these radios, then my communications are exclusive and private", not unlike having Wifi, but leaving it open with no password required and blaming the guy who is using it without "permission". Or maybe, buying an airplane and just flying it wherever you want, whenever you want. Not quite the way it works.

It's probably an ID'er on a repeater.

Do you want something cheap or something that works (decently well)? I get it, I mean not everyone has money to throw at this hobby, but the best experience is had with moderately good or better equipment. Some of this stuff on the market I would not touch with a 39.5 Foot pole....or an low band 1/4 wave whip....for that matter. I have a UV5R, it has so many quirks, I consider it a toy more than something that I rely on.

I have NOAA alerts on my repeater, 45 second time out, just because that's all you really need to get the point of the alert. I concur that the VHF is sufficient, but we don't keep weather radios in the vehicles or on our person at all times, so it's convenient and good for safety sake, especially in the middle of 1,000 acres.

Interconnection, Wireline and PSTN references are all in rules that are pre-dating internet. They all pertain to switched telephone services and dial up connections voice audio. They do not pertain to point to point leased lines (that do not run through a telco switch) and they do not pertain to internet. Period. I worked with all this stuff, in commercial radio, back in the early 90's when only 1 guy in the neighborhood had dial up internet! There is no use debating HOW the internet is delivered or routed, it doesn't matter, internet is not PSTN in any form.

Most modern ones will back the power off on their own based on heat. I also set my 40 watt radios at about 35, and on my older M1225's I run 35 in hi, and 6-7 in low. With a 1/4 wave, 6-7 works great 80% of the time.

I don't see much of an issue with any of it. Might simplify things a little, doesn't affect me at all from what I can tell.

I've been using my Uniden GMR-1048's a bit. I managed to find 4 of them, used but in new condition. Speaking of privacy, this model was taken off the market because it was FRS/GMRS and it had a the voice inversion scrambler. I love these for travel.

A couple of years ago there was a Doctors office near me that was using GMRS. I set my simplex repeater on that frequency and PL for a few days...after that, never heard them again. I guess having to hear themselves repeated back all day was annoying! Imagine that.

I ditto on turning the power down. 20/25 will do as well as 40 in most cases, as the higher the tx power the more chance of drowning your input, even with dupexor (unless you are spending $3,000 on it, and even then I have turned them down to necessary power only. When I worked for M we had a customer that used a 25 watt mobile for 2 way and phone interconnect, and 2 HT600 portables, but her repeater antenna was on a 500 foot tower she owned. We had the repeater all rigged up blowing A/C directly into it, as she liked to use that phone for 20-30 minutes at a time, and it was an R100 repeater! We had it set down to get about 2 watts out the antenna, and it had great coverage, more than she needed. Input path to the repeater will determine the usability in most cases not power out. Too many guys have CB mentality, not what you need.

If anyone needs a couple of used 40 watt UHF M120 Motorolas, I have 2 left to sell. I sold the 10 watt ones on eBay, but these did not go. Asking $100 each. Clean, working, tested and I can program. Brackets and Mics if you want them, no power cords to spare, but they are easy to find.

True, but I have heard hams use the term for the voice repeater, because is used digital recording. No big deal....just sharing.

I built a high powered one years ago to do some range testing. They can get a bit annoying to use for regular communication. Mine was PC based, I built the interface to a Motorola Raduis 40 watt mobile, and used Echo Station for the operations. You could trigger recorded messages with it, it would ID for you...etc. Good for testing range. I have heard them used for tactical type setups, usually with a PL on the input and none on the output. So you can use the simplex without PL at all if you want to go around the recording. These are also sometimes called "digi-peaters".

There are commercial industrial operations in that area, like power companies, contractors that move around and don't use repeaters. They use low band for longer range simplex. There is at least one itinerant in there...it may be 33.04, but need to look it up. Low band radios fall in 3 bands, 29-36, 36-42, and 42-50. Back when I worked in radio professionally, we have business customers and public safety/services in all 3 bands. Upside - long range...especially to a base. Downside - radios draw more power, larger antenna on vehicle, and harder to match the antenna given mounting choices on newer vehicles and their materials.
