I have not had any problems with my Q10H yet. But I have had other brands of radios act up. though usually just reloading stuff fixed them. I've had Icom and Yaesu radios have glitches too.

I hated when I had to carry the PRC-77. At least I did not have to carry the PRC-77 at the same time carrying the M60 machine gun. The only SINCGARS radios I dealt with were vehicle mounted. They were heavy enough trying to carry from the shop to the vehicles for installation.

That is how we have our repeater controllers set. The Arcom RC-210 will lower the volume of the voice and CW id if someone is transmitting at the same time. We will have the RC-210 set the same way except for every 15 minutes iso there is traffic for our GMRS repeater. The main complaint about the Bridgecom repeater is how it will interrupt and cutoff anyone that happens to be transmitting at the same time.

I agree.

We had the SINCGARS radios when I was in. They came out shortly after Desert Storm. We were not allowed to use them in Germany at that time since the constant frequency hopping messed with German civilian communications and broadcast stations.

Well no need for the attitude that you displayed nor was there a reason for name calling. Even the best of us will overlook the simple things when trouble shooting. I won't bother to try to help you ever again since you want to get an attitude, Good luck figuring things out.

All the Sky Warn Nets (weather reporting) are normally done on local 2m repeaters. That's not to say a local group could not run a Sky Warn Net on GMRS as long as the repeater owner is okay with it and you have people that can report directly to the NWS. We do not use our GMRS repeater for Sky Warn Nets but most of us do monitor it just incase during severe storms. We were asked about running a Sky Warn Net on GMRS but that would take away from our 2m Sky Warn Net as we are only allowed so many people that can actually report directly to the NWS. We don't have enough people that can report to the NWS to run two nets at the same time.

First off. Are the TYT radios that you are trying unlocked for GMRS? I ask because the TH-7800, TH-7900, and TH-9800 are amateur band only from the factory. Which means they won't transmit on GMRS. Next What antenna(s) are you using and have you checked the SWR on them? How far away are you from the repeater the trying to talk with the TYT radios? I have two TH-7800 radios that have been unlocked and they will connect to any and all repeaters I can reach as long as I have the tones correctly programmed. I've talked on BTech, Bridgecom, Motorola Quantar and other brands of GMRS repeaters without any issue. Double check your setting on the radio as it should work no matter what brand of repeater you are using.

I have tested a few 20 watt mobile radios and they only go down to 4-5 watts on low. And that is why mobiles are not allowed to use channels 8-14. Every Part 95 certified GMRS hand held will transmit on channels 8-14 and they will automatically transmit on low power even if you have them programmed to hi power, or at least that's how my Wouxun GMRS hand held's are. All bets are off when using unlocked/modded radios. An unlocked amateur mobile will transmit on channels 8-14 on any power level the radio has. As others have mentioned. just use channels 1-7 and 15-22 and yo will be fine. Someone with their GMRS license can use a 50 watt mobile to talk to someone using an FRS radio on those channels without issues.

This is true for those using two KG-1000G radios as repeaters.

I received the same email. I want to do some more research to see if they will ID every 15 minutes 24/7 or if it can be set so that it only IDs every 15 minutes when there is actual traffic on the repeater,

There are two other repeaters in Missouri using the same channel and PL tones as our repeater. One is in the Kansas City area and the other is just outside of St Louis. We are located towards the middle of the state. Here lately with the temperature inversions, one or both of those repeaters have been opening up our repeater. The closest one is 80 miles away. And no we do not see anywhere near 100-200 miles of coverage on UHF here in Missouri.

Glad I could help you spend money The black screen is definitely easier on the eyes in bright sunlight and at night. It's worth the extra $50 for me. I can't answer your question about swapping the remote heads between the radios since I have not tried it. I have not noticed any differences in the two radios except for the screen colors. Both work equally well on 2m and 70cm. I didn't bother doing the mod on my 2730B since I am not impressed with how my 2730A performs on GMRS. I've tested the 2730A against my TYT TH-7800 and my Wouxun KG-1000G. I've tried all three with my Comet CA-712EFC and Comet GP-9 antennas. The modded 2730 does not receive GMRS as well as the TH-7800 or KG-1000G no matter which antenna I use. And everyone says my transmissions are louder and clearer with the TH-7800 and KG-1000G

SOP hasn't changed, one still has to keep transmissions short to keep the enemy from triangulating your location. The Russians and Ukrainians are finding that out the hard way. Difference is you now have to worry about drones along with missiles and artillery. Signals are scrambled and most military radios use frequency hopping but the can still be located if they transmit too long.

The Kraken system is like a child's toy when compared to what federal agencies and the military have. Even the equipment we had in the 90's was still better than the Kraken. We had no problems triangulating exact Iraqi positions back in 1991. And don't think for a minute that the feds are not using that kind of equipment right now. Transmitting briefly is standard SOP when using any military radio and has been for a long time. Transmit too long in a combat zone and you will get a missile or artillery rounds down your throat.

People epoxy sheet metal to the underside of toppers all the time. And that works fine for a ground plane. Having good contact between the NMO mount and a sheet metal ground plane is what matters.

RG8X has around 86% loss over 100 feet while LMR400 has around 48% loss over 100 feet. Plus the fact that the center conductor, insulations (dielectric) and shield braid are bigger with LMR400 which helps reduce loss. @WRDJ205 your real world measurements are close to what most online coax loss calculators will show. While a j pole is not the best antenna, they work just fine. I've seen enough home made UHF j pole antennas built from solid copper wire that works well. No they won't have as much gain as other designs but nothing wrong with a J pole.

It depends on the agency and what equipment they have available to them. I know that 20-30 years ago, we had equipment in the military that could triangulate a transmitter quickly. Even today's systems such as the Kraken SDR can pinpoint a transmitter fairly quickly, and two or more Krakens in different locations and the time to pinpoint a location goes down. One Kraken will get you pretty close and do so in a reasonable amount of time. 2 Krakens will do it quicker and with more precision. Three or more Krakens will be even more accurate and take less time.

You will always lose some power output through a duplexer. The power loss can be anywhere from 30% to 50% depending on the duplexer and the repeater used. The Retevis and Midland 10 watt portable repeaters lose half. They only putout 5 watts after the duplexer. Why compromise your setup when you don't have to. Tune the duplexer for the exact repeater pair you plan on using for the best performance.

Tuning a duplexer for a single pair gives the best performance with minimal insertion loss and better isolation from other frequencies/channels. Yes you can tune a duplexer to cover all eight GMRS repeater pairs but that is a compromise. Doing this increases insertion loss and reduces isolation. Both will lead to poor performance. And the whole point of a duplexer is to isolate the repeater pair from other frequencies/channels.

This is true. We got away with way more when we were kids compared to today's kids. There were no cell phones and not many had the 16mm cameras to record stuff. And one could just throw away any photographs and negatives. On topic. It is pretty easy for law enforcement and the military to monitor and track two way radios and cell phones. They can't hide unless everyone leaves all electronic devices at home. Some people have had warrants issued or have been arrested by using cell phone data and/or security camera feeds.

It could be a number of different things causing the noise. Knowing what vehicle he is using and how it is powered will help. All of the LED bulbs and computer modules on newer vehicles can cause noise. I had to put clamp on ferrite beads on the wires powering my radios and I even put one clamp on ferrite bead on each end of the main wire going from my alternator to the battery on my 2023 Ford Escape. I still get an occasional whine when transmitting. But it doesn't happen often enough to chase down the source. Another thing people sometimes overlook are al of the LED street lights and LED bulbs used in homes. I know the cheap LED lights in my garage are very noisy on 2m, 70cm and GMRS. I don't dare try to use any 2m/70cm or GMRS radios inside the garage with the lights on. Power transformers are another source of noise if they are starting to go bad and/or have bad connections. Solar panels are another source of noise.

Here is the difference between the 2730A and 2730B for those interested.

An old thread brought back from the dead. The 2730A is a nice radio. I do find that it does not do so well on GMRS with the MARS MOD compared to other modded/unlocked radios or Type 95 certified GMRS radios. I can highly suggest the 2730B with black screen over the 2730A with its white screen. The $50 difference is worth it. The 2730B screen is so much easier to see in bright sunlight and easier on the eyes at night.

More information will allow us to help you better. Noise can come from many sources. Alternators, spark plug wires. cheap LED lights, using an accessory port, wiring directly to the fuse panel, etc. The best way to connect any two way radio in vehicles is to run the radio's positive wire directly to the positive battery terminal while running the radio's ground wire to a chassis ground. You do not want to use the battery negative terminal, especially on newer vehicles equipped with battery management systems.
