He/she didn't mention anything about a repeater. But it was on those lines of thoughts. I mean when we camp, although I want to be in the trailer next to a radio. That rarely happens. Gotta cook, tend to fires or sit outside with the brew and mellow. Sent from my SM-S901U using Tapatalk

Me personally. I would mount a harbor freight telescoping flag pole to the trailer side, it extends 25 feet. Then mount something like Fong jpole to the top lmr400 flex co-ax. Have a patch pass through into the trailer with a jumper coax to a mobile radio ( lets me have extra power if needed) in an ammo can, make so I can disconnect outside of the trailer for storage. As well as, have extra spooled cable for when I disconnect the and connect extra cable outside and move the ammo can outside. Power would be provided by something like a jackery aux power supply. That way I am not tethered to the trailer. Could even use an rt95 repeater in this kinda setup extending some range. Point of this setup is to get the antenna as high up as possible. Frankly, I just sling a slimjim roll up into a tree and get something of the same effect. Have you thought about something like a meshtastic or garmin reach? Might be cheaper although it is not voice. Going to depend on range, terrain, and budget. Ht to ht (realistically max a couple of miles through vegetation) is not going to go far. VHF service like MURS might get further. If you had a repeater where the antenna was 100 feet up different story. You didn't mention what the TT (travel trailer) is nor other specifics.

Yup like 1/4 wave said. You should be fine. Sent from my SM-S901U using Tapatalk

What kinda of distance are you talking about? Sent from my SM-S901U using Tapatalk

Except most radios (actually I think all) are not tested by the fcc. But rather a third party testing house. Don't believe start pulling the FCC certs and look at who signed the certification testing. Sent from my SM-S901U using Tapatalk

Pennsylvania state senate passed a bill to disallow mobile usage. Some wording was changed to disallow mobile radio usage aimed at amateur radio. If the governor signs this bill with the wording. You as a gmrs/cb user will not be able to legally use your mobile radio on the road. This excludes public safety and commercial operators like taxi cabs.

That is mighty nice of you. I mean it's not like the cost to get a pair is super expensive. But most administrators off the bat would of not offered or put secondary user stipulations even the if pair wasn't used. You know "in case". Sent from my SM-S901U using Tapatalk

No one has mentioned if gmrs is used. All the household users or non-related users will need to be licensed. It will probably be better to get an lmr/commercial license. Sent from my SM-S901U using Tapatalk

Unfortunately, most government radio admins want to play God. I wonder if it was the county council that enforced the requirement or each depth voiced they wanted that requirement added. Either case, it's the people that won. On the next county over I often hit dead spots with their system. It's funny to see in other counties every one running multiple high gain antennas. Where in moco almost all the vehicles are running low gain antennas, minus the few exceptions. Sent from my SM-S901U using Tapatalk

Around here (montgomery county maryland). Local municipality set up the radio system properly. Public service network on 800mhz. They could of gone with lesser equipment and use higher gain antenna. But chose to go with a mandate that required 98% coverage of the county with an ht. Yes this included in people's basements and in parking garages. What they needed up with was a 2 site simulcast system. It is one of the best systems in the country. I have used the harris xg100m and a g5 unification in some absurd locations with the ability to listen to the county radios. Either case, the state police use part of this system as well as many other agencies. Each pretty much has their own main talkgroup and tac channels. This includes the cert (was react) teams. But it took a lot of handshakes and negotiating from multiple people to get it the way it is. But as a public safety group you might be able to get the local council, pd, fd and ems onboard to get you some talkgroups and interop group channels. Hell they probably have some old xts2.5/3k/5k. Hell 700/800 Mhz Motorola gear are dirt cheap compared to the vhf/uhf r1 counter pars. Think like $60-80 vs 200-500 for a unit. Sent from my SM-S901U using Tapatalk

Actually makes me wonder about advance programing functions. Like stun, deny list by radio id's, split tones etc. As well as what they have rated for duty cycles. Sent from my SM-S901U using Tapatalk

Spectral purity info would be nice. As well how sensitive receive is. Maybe a flir/thermal image after some usage. I am curious about were energy is most wasted in the radio. Only to see what part may fail first. Edit to add flir request. Sent from my SM-S901U using Tapatalk

If we are discussing simulcast, and lora back bones/ radio. Why is the group not talking to the local pd. Who probably has simulcast already set up. Old gear that can be repurposed, get potential federal grants and be administered ( really only sounds like you need 1-2 tac groups). As well as the license for the extra frequencies. Probably can be encrypted as well. Sent from my SM-S901U using Tapatalk

Gmrs 18 should be simplex. Rept 18 should be the repeater pair. Which is what you should be using to try communication with a repeater. Well that is how most radios are set from the factory. So radio to radio it should be on gmrs 18. The map view of the map on this site is not very good when it comes to repeater footprint. Well hell accurately measuring footprint kinda sucks to begin with. I would kinda ignore it. Do you have the proper tones set? Where you trying inside of a car? If in doubt get as close to the repeater as as you can and high as you can. Try again at that point. Sent from my SM-S901U using Tapatalk

Agreed. It's been on the market for what a year? Maybe there were no offers that came close to what they wanted. Sent from my SM-S901U using Tapatalk

The biggest problem is they bought so many companies. If they go under we lose all lot of companies. Like ameritron. Albeit many of them would be gone if MFJ hadn't bought them in the first place. Sent from my SM-S901U using Tapatalk

Thought it was a rumor on reddit. They have been trying to sell. I really thought dxenginnering was going to pick them up. Sent from my SM-S901U using Tapatalk

If the repeate comes up and you still can't make it. Might be worth finding a high peak closer to the repeater. Especially, with a ht. Not all repeaters are created equal. Sent from my SM-S901U using Tapatalk

You do not have to have a tone on receive. Since the tones block incomming messages that don't have matching tones. You would hear it if no tones are set on your radio, even if they have tones enabled. If you don't have tones on receive you will hear all transmissions on that frequency. No tones on encode shouldn't not be done (most repeaters have tones on input). So that it will ignore and not repeat any transmission that don't have matching tones. To complicate things more, there is cross repeater talk as well as repeaters with multiple tones. Sent from my SM-S901U using Tapatalk

Simple answer yes. You encode a transmission and decode on reception. Is a simple way of thinking of it. Sent from my SM-S901U using Tapatalk

Shouldn't 2 different frequency segments. Guess you are going to have to send it and find out. But not 100% since non adjacent frequencies can still wipe each other out with enough power, suppression of harmonics. Especially, with antennas less then 1/2 wave length away (longest wavelength/ frequency). Sent from my SM-S901U using Tapatalk

For my 70cm gmrs hts. I usually use what is supplied with them. Aka my motorola xts5ks. For my ham radios (2m/70cm/aprs and gmrs) I have found stocks antennas are ok. But the stock rubber duck antennas did the best job trying go across such a wide bandwidth. Even the signal stick was barely an improvement on the 878uv, caused intermod issued with the Feng bf8hp for me at least. For my gmrs hts I usually swap them for Nagoya 701c and they perform admirably. The harris xg100m. The long high gain antenna works the best. It's tri band and is adequate. Real short, stock rubber ducks work fine. If it is a gmrs specific ht. I found the Nagoya 701c a good antenna. Sent from my SM-S901U using Tapatalk

Usually, the seller has the feature sets or options that the radio has. Sometimes they will have a screen capture of what the programming software read or you can inquire to the seller about said information. Sent from my SM-S901U using Tapatalk

There are some videos on youtube. Which are really good at teaching things like programming p25 in astro25. You are going to want to narrow down your radio choices first. Each software is different and has different quirks. Generally, they program similarly to any other radio. Just with different terms for the same thing. Unfortunately some software like Harris rpm. There aren't videos, they kinda expect you to already know or attend harris training. Then it's a matter of playing with the software and figuring it out. For Kenwood, you have Lscott [emoji14] I for the most part think the Motorola software is one of the easiest, since it's straight forward, well for me at least. F harris.. nac code says its hex in software , but it isn't actually using hex its decimal...lol Sent from my SM-S901U using Tapatalk

Stand corrected then. I don't load encryption keys on my radios. All my hexedits and feature additions are done by handful of friends. They are the ones that actually know the intricacies. Sent from my SM-S901U using Tapatalk
