2 years ago we tried our GMRS radios during a river crossing, all worked well. Kentucky Adventure Trail (KAT)

We had a few members of our club look down on GMRS and give the rest of us with our GMRS licenses trouble. Those guys really poured it on when we started talking about putting up a GMRS repeater. But guess what, a few of those guys giving us trouble now have their GMRS licenses now.

For one radio I use a Midland MXTA26 on a cookie-sheet in the window, connected to a KG1000G. My repeater AND my XTL5000 are both connected to a Tram 1486 on the roof. Both get me ~75-80 miles of farz which is about my limit because of the geography, but the 1486 on the roof can pick up a LOT more/much weaker signals.

The virus warning is a false positive with the 935G programming software when downloaded from Buy Two Way Radios. Myself and several others run it without any issues.

Impossible! I have been assured by multiple people that have "....Been a licensed H.A.M. radio operator for [insert years here] years" that these people do not exist and NO H.A.M. operators are like this, and the certain youtubers just make up these stories.

If I follow what you're asking, you would have radio users on one system (non-GMRS) with the ability to generate traffic on a GMRS repeater. It's not going to be legal. If you end up relaying their voice traffic from this 'private' system over to an analog GMRS repeater, I also question how 'private' the system would remain. You would be basically be wiretapping your own private system, and then broadcasting the audio over an open analog channel.

The XTL5000s in my Jeep and in my wife's, both work in water and on land.

Jeep JT pickup, Sport model, stock height, 32" LT-E all-terrain tires, various control arm and shock skids, aluminum engine and transfer case skids, hitch skid, bed skids, the wider Mopar HD rock rails with step assist, Apex Autolynx sway bar disconnects, Bilstein 5100 shocks, Timbren SES rear bump stops due to bed cap and towing hitch weight, Timbren offroad front bump stops (not yet installed), bed cap, Midland 275 GMRS behind the dash under the steering wheel, 1/4 wave mag mount on the hood on a sticky plate, upgraded coax, Garmin Inreach Mini 2. We tow a hard-sided popup and get decent fuel mileage as we cross the country from the midwest to get anywhere interesting. Did some Ouray and Moab, plus a bit of VA out east. With the engine/transfer case skids sticking down a bit, and no lift, it can scrape a little on two track. On the other hand, it's awesome for carving up twisty mountain roads. Like many others here, I have to get my family to and from some pretty distant places, so I can't take "might break something" risks. But a single trip blew the stock front shocks, and the skids got some scrapes, so I'm not totally babying it either. I used the InReach a few times just to update the family while they're back home or in camp. I used GMRS once while they were in the trailer a few miles away with a mountain ridge between us. Made a thread here about how the signal was probably going along the valley, bouncing off the mountain at the end, then up the next valley to the trailer. I had the 1/4 wave on the Jeep, the family had a half wave on the handheld in the trailer. Heard some groups on GMRS while on the trails out west. Heard some locals in various areas during cross-country travel. GMRS is out there in rural America, usually being used w/o call signs.

Me too. I'm still disappointed.

I’m not sure if I follow. I’m not going to speculate about the legality without fully understanding what you’re describing. It sounds like you want your friends to use GMRS handheld or mobile radios to talk to an GMRS repeater which is patched to another, more private system of some sort. What is that “more private system?” A diagram would be helpful.

Turn on squelch. It’s purpose is to mute the radio unless certain conditions are met: Carrier squelch mutes the radio unless a threshold signal strength is exceeded.

False positives from Norton are quite common and that's the main reason I stopped using Norton several years ago.

The Comet CA-712EFC is definitely a good antenna. Though my Comet GP9 dual band antenna also works well for GMRS.

I have found that my Jetstream JTM3B does pretty well on GMRS. I normally just use it for amateur 2 meters and 440, but I was surprised to find that it has a decent match on GMRS also. I set it up on a 20 foot window washing extension pole. I can't leave it up all the time since I live in a condo with an ASSociation.

Many people have reported this with other manufacturers software and it has always been a false-positive, but I don't recall seeing this mentioned with the 935G software.. Where did you download it from? The only safe/trusted source would be from BuyTwoWayRadios.com .

Last contact with his unit… Boris you go over there and we’ll call you on channel 15 if the area is invaded and there is a risk of capture. Some time later… Boris says to no one “I don’t think channel 15 is working”

You are correct, I can confirm one year as my friends needed updating recently.

@roo_ster Welcome back to GMRS. I haven't been at it for all that long but have use it quite a bit since I started. CB doesn't have nearly as many offerings in HT as GMRS. I've used GMRS in the mountains around Cloudcroft NM and didn't have any problems. Although it is "line-of-sight" it isn't like a laser. My son was constantly out of sight around fingers and over hills and we never lost contact. The only problem I have had so far was trying to penetrate all the trees and houses in my neighborhood. That's were more power really helps. Bumping up from 4 watts to 7-8 watts made all the difference in the world.

I mention the rules thing for one reason only. If it's not brought to to the forefront in the initial discussion, then it will be discussed, debated, and pontificated by a number of folks that may or may NOT have a solid understanding of it and possibly convey partly or completely incorrect info that then needs corrected. This always seems to turn into a thing, threads get hijacked, dead horses beaten. It's just a thing that happens with online forums. Nothing new or exciting, just a continuance of the norm. Unless you are connecting your .5 watt radio to a 30dBi gain 20 foot dish and purposely creating interference for others I seriously doubt that the FCC is gonna come knocking. That being said. You mentioned both dBi and dBd gain numbers. Gonna give a quick explanation of each, because it's not common knowledge. dBi is gain over an isotropic radiator. This is the default 'paper' reference antenna that radiates RF in all directions at all angles equally. It's basically a free space radiator that has a sphere of RF eminating from it. I know that I used a lightbulb as an anology, and it's not quite correct since it can't radiate out the bottom of the lightbulb, but it's a good point of reference for most all other directions. dBd is gain over a dipole. Dipole is simple, and does exhibit gain over an Isotropic radiator since it's pattern doesn't include significant radiation off the ends of the antenna. That power has to go somewhere, so the increased radiation at certain angles give the antenna some amount of gain over the paper antenna in those directions. One of the other interesting things with antenna's an gain as opposed to amplifier gain which of course is an active component of the RF string is the amplifier is typically uni-directional with it's gain. Take a typical amplifier with a 10dB gain design. You put in 1 watt and 10 comes out. This will make you be heard farther than before. But it does nothing for your receive. Now, gain in an antenna doesn't so much 'boost' the receive signal. The signal is what ever it is at the antenna. Once again, we bring in the light source. The light isn't brighter for the directional antenna vs the onmi directional antenna. It's the same level. I am not going to bore you with math and what is referred to in the big antenna college text books as power density. I am gonna go back to the simple light source. So what a directional antenna does to increase your ability to 'hear' a signal is it darkens everything else out other than what it's pointed to. Take a flashlight outside at noon, you can see it at 100 yards. But you can't see a candle at the same distance. There is too much other light source (noise) to see the candle. But take the same candle out at midnight, and it can be clearly seen as a light source at the same distance. The directional antenna does this by ignoring the light (signal) from every other direction and only looking at the candle. A receive amplifier can't do that. It's going to amplify the signal some, but it's going to amplify all the other signals that we don't want as well.

Is he really an amateur extra though? He never tells us how long he has been an extra class operator and everyone knows you are supposed to let everyone know how long you have been a ham. I ought to know, I have been an amateur radio operator for over 20 years.

I’ve known GMRS users who have no interest in ham radio and (unfortunately) I’ve known ham radio operators who have a derisive attitude towards GMRS users who reject ham radio and then attempt to make GMRS into a no-test substitute for ham radio. But here in Montana I have not personally encountered any hams that look down on the licensed use of GMRS for group communications.

...or maybe @Sshannon was just trying to help someone out solely for the satisfaction of helping them. Unfortunately "some people" have no gratitude.

I came here to read about Terry Sullivan, not some dumb question about a radio! Clickbait!!!!1
