What OS are you using? Because, yeah, what @SteveShannon said. Pretty much any OS has an on-board program to deal with zip files natively.

Why would you need a PA for? In most communities it is illegal to use a PA in a vehicle if you are not Public Safety.
What would you need a Jeep for? In most communities it is illegal to drive off the pavement.
See how that reads?

Don't many mobile radios have an audio out port for an external speaker?
yeah but that's a pretty different function than a PA, where you're talking into the mic and the same unit is outputting the audio, but louder.

how many stop-signs have you rolled through in the last month how how many times have you exceeded the speed limited by more than 1/2 mph?
Bingo.

they are just required to lockout those first 30 for fcc approvals.
Nope.
A lot of them do because it *can* decrease confusion in new users. What's required is that the radio enforce the rules. The rules don't say anything about what memory slot a frequency sits in.
My "nice" GMRS radios (nice for me...), KG-905Gs, will force the radio to low power if you put, say, GMRS Channel 8 in memory slot 20, or allow high power and frequency offset for repeaters channels if you put them in, say, memory slot 8, where a low power interstitial channel would normally go.
Lazily programmed (from the factory, I mean) radios force things rigidly in place because it's easier than enforcing the rules more broadly.

Not so sure about bigger better antenna doing anything to the immutable impenetrable hill. But getting it above said hill will do the trick.
now if the antenna happens to be shaped like a Cat D9, it might do something to the hill...
But other than that, no.

If the trailer gets loose, you've got much bigger problems than damaging your coax.
Of course. Depending on the trailer and what's in it, it could be a REALLY bad day.
It'd be worse if it takes your headliner or half your dashboard with it, depending on where the radio's mounted and how the cable's run.I'm just saying that, in my opinion, the juice, what of it there may be, just ain't worth the squeeze of dealing with a remote antenna.

This is why you need stupid people to write the actual regulations. They'd spell it out instead of referring to this which refers to that which in turn refers to something else.
I once had a professor in a technical writing course ask the class "do you know why all your user manual and instruction manuals for the things you buy are by and large all terrible? It's because the person they get to work with the technical writers to put together the manuals is the guy the shop foreman or engineering manager can most stand to do without for a couple weeks. And do you know who THAT is? Literally their worst and / or dumbest employee."
Which is a long way of saying "no, I don't think getting stupid people to write regulations would actually be an improvement"
Should they be written in plain language instead of legalese and spell things out? Oh absolutely.

A quick google shows a handful of instances of interference if you're sitting right on 433 (either the TPMS light on the dash coming on when you transmit, or occasional noise when receiving. At least 1 seems to have fixed it by moving the antenna.

Short answer: yes. I don't know what brand you're looking at, but the OEM giant in this space is Continental and:

My thought was it removes a great big blind spot.
Theoretically?
Sure.
In practice? I'd be surprised if it was more than a fractional difference all the way at the edge of the performance envelope. -
That janky cable is usually built into the trailer, and to a connector built into the tow hitch, with a breakaway connection should stuff go wrong. Not something you're stringing across the bed of a truck to a trailer. I guess you can test the failure load of the SO-239 connector on the back of your radio if things ever go really wrong lol

There's enough stuff that can go wrong with towing as it is. I don't know if I'd want to add a janky cable between the tow rig and an antenna on the trailer for the fractional theoretical gain you might get over just having it on the truck which, I'd assume, is where the radio also already is.

If I hear any kind of chatter, I go to another GMRS channel.
Kinda same, honestly. Unless I'm testing out a new radio or install, I basically never talk on the radio to talk on the radio. We're at the track or strung out along a hiking trail or in a group of vehicles driving somewhere and we need to talk amongst our group, not really to anyone else. Other people on frequency means we're moving to our secondary channel haha

My question is: I, with my 20w would be able to transmit farther (in most conditions) than the 5w handhelds -- so does that mean that if we got separated a number of miles on the highway, they would be able to hear me from farther away, but that I would probably NOT be able to hear them calling back, due to their lower power?
For transportation communications like this, would it be better for all of us to have the same power handhelds?
As has been said, you may get SOME additional punch through trees and what not at 20W over 5W, but the biggest thing is putting the antenna outside of the big metal box.
The nice thing about it though is that with the antenna on the outside, not only does it improve your transmit range, but you'll be able to hear them from further away than you otherwise would as well, with a handheld inside the car without an external antenna.
All that said, if staying in touch is super important to the group....if a large separation happens, have a plan for correcting that / regrouping.

I have yet to see a mobile radio in a race car. Every radio I have seen is a portable with an antenna adapter. I dont know if indy or F1 is different but at least in the nascar world its all portables. Rarely do you even see a mobile in a safety truck either. If you are doing a mobile I'm with others get a quality LMR radio with limited functions.
Really?
Even at club level road racing (SCCA / NASA) I've seen a mix of mobile and H/Ts. Once you get up into your IMSA / WEC / World Challenge, even the lower tiers, it's basically all mobiles. I haven't spent enough time crawling around circle track cars to tell you one way or another in that world.

I think it does. I'm not sure because I'm not interested in listening to air bands.
Edited to add: It's advertised as receiving AM 108-136 MHz. Does that cover the air band?
Goddamn it, it sure as hell does. A quick look at the amazon link made it look like it was broadcast AM/FM radio, not VHF AM / FM.

The AR-5RM is a very nice radio with a lot of capabilities for the price. It was my favorite radio for a long time. However, I recently bought a UV-5RH Pro GPS which does everything the 5RM does with some added features. The one I like best is the ability to arrange my channels into banks and scan only one bank at a time. It's only slightly more expensive than the 5RM on Amazon. If you don't care about the banks or GPS, though, you may as well buy the 5RM and save the $6. You really can't go wrong with either.
dang, if that had air band receive it'd do basically everything I wanted

I figured this out: Channels 15-22 are set to GMRS frequencies and you can enter a tone for the repeaters, but you are talking simplex so the repeater does you no good. To access a repeater you must be between Radioddity's channels 23 - 40.
Those aren't "repeater" tones. Sometimes there's uses for tones in simplex comms. In fact, if I'm in a group traveling together, we almost always have tones in the radios so we're not hearing anyone else who may be making noise on the radio.
But yes, your normal channels 15-22 will be simplex on most GMRS radios, and then 23-30 will be your repeater channels, then you'll be able to program in some 'DIY' channels (usually repeaters, is the idea) in the additional space.

If you and all of your buddies don't have Amateur licenses then NO you can't use the Ham repeaters under any condition.
Really? Under *ANY* condition? Because I can think of a couple carve outs in the rules...
The scare-mongering and disinformation is getting a bit silly.
