The most disturbing paragraph to me was proposing people holding an amateur radio license could volunteer to be the radio police for both GMRS and the proposed GMRS+ services. I guess having an amateur license makes one superior to the folks on GMRS. I have a "HAM" license and a GMRS license and I am not better than anyone. I'm sure there would be plenty of volunteers for that gig.
Must be one of those with a stopwatch that jumps in at 10 min 3 seconds to yell at other about identifying. Must really drive him nuts that FRS has no obligation to acknowledge GMRS rules.

And your repeater users are tying up the same (output) frequency that is for simplex use, not to mention possible use by an open repeater. [But it's FCC's fault for creating that mess.] The only really relevant point here is you having a repeater doesn't give you control over stations that are not using your repeater.
This is true, but considering 95% of my family's traffic is actually simplex, not using the repeater, we use the corresponding output most of the time. The public use of my repeater is pretty minimal as well. Overall, I don't see it as a problem. It's EVERYONE's responsibility to minimize interference with other users as much as possible. Unless you are at a large amusement park, its pretty easy to find an unused frequency.

I'm not going to get into issues with specific repeaters. But almost all recently updated or new repeaters are either permission required or members only. They're turning this public spectrum into something more like business radio.
Personally, its not that I don't want others to use my repeater, but I do want to know who is using it. It also helps if I have to make a change, that I have a list of people to notify.

Depends on what the measurement is for. If you are modeling the RF horizon, you go from the bottom of the antenna. If you are dealing with zoning, then top of the antenna.

VHF Lo may not be a bad thing, there is 1 itinerant in VHF Lo.......
-
I thought I saw one thread on cobbling together an amplifier/filter set on RR. I'm not exactly interested in transmitting though, but if VHFLo was available to listen, I would like too listen.
If only someone had a way to expand the VHFLo to 6 or 10 meters.......
-
Yes, I have terminators for both unused ports. It powers up and cycles through channels and zones.
I'm still undecided if VHF low is worth doing anything with. I don't see it being used in Ohio anymore, for anything. I also don't want to deal with another antenna.

Waiting on a TNC to N adapter, but I have some more information/observations to add.
CH721 head (system) is not terrible to use, but I glanced over the fact that you can only have 1 mission plan. You need the elusive and expensive CH100 to hold more than 1 mission plan. The HHCH has same features/limitations as the CH721 head.
Programming is through the brick DB9, not the head DB9.
When applying power, read the manual for control head setup. You will get no power/activity if you don't connect the ignition sense wire to power. This is on the head side, if you don't want ignition sense, hardwire the white wire to positive power, otherwise attach it to ignition sense power.

I'm pretty sure there are a handful of comments "pending", including mine. Interesting to read through the comments, they all pretty much mirror my sentiment on the deal.

Did you ever get one? I missed out on picking up one of the touch screen heads.

A matter of fact, Part 90 Type-Accepted radios are not Type-Accepted for Part 95, GMRS. These days, the FCC will only issue one Type-Acceptance to a radio device and if they are going to allow that radio device to be used in another radio service then there will be a rule in the affected respective radio service rules to allow that device to be used. And, if the FCC is going to prohibit a particular radio device being used in a particular radio service than the respective radio(s) will have a rule stating the fact.
This is not necessarily true. Almost all of the current VHF LMR radios with Part 90 acceptance are also granted Part 80 acceptance (marine radio). I think Part 95 is not worth the time/money to request certification for anymore.

They don't. Only the repeater owner is supposed to submit their own repeater.

Bumping this thread. Did you ever put one of these together? I'm looking into one, but I'm missing some information and maybe some hardware.
Did you confirm programming can occur directly through the DB9 using an FTDI?
Do you have a pinout from the DB44? Any idea on what pins are needed for 3pin keyloading?

Some more info, and some questions.
The TAC1 battery/charger is a dropship from PowerProducts. Charger is an Endura, which is top notch. I get 14+ hours on a single charge. Would buy again.
I ended up buying the 9" antenna from NLT, brand new. It is a significant improvement over the 6" on VHF. UHF/7/800 no noticeable difference. The flexibility of the antenna is a huge improvement as well over the 6".
Has anyone found any bluetooth compatibility, other than OTTO? Still looking for a listen only BT ear piece.
Anyone else have a VC4000? I think I will grab one, but some of the ones I see for sale don't have the cord, just the charger brick. Any idea where to get the power cord?
One other thing, my "feature list" doesn't use the numbers, but lists them by name for most. Anyway to get more information in RPM? I'm interested in a few that I never heard of. Radio info further confuses me.

DX Engineering's 400MAX cable is identical to TimesMicrowave LMF400 Ultra Flex.

Well, few weeks use impressions:
1) OEM Harris battery with 208 cycles on lasts a "work" day listening, and that is about it. I do have a TAC1 4100mAh battery and charger on the way. I'm also on the hunt for a VC4000 charger for the car.
2) The radio isn't as heavy/big as I expected. I do have a Harris leather holster for it, it definitely is better than the belt clip when running around.
3) I didn't intend to use it as a listening device, but it does it extremely well, and is easy to program. Enhanced CC for those that know.
4) The 48 channel (ABC switch) "capacity" is annoying coming from the NX-5k infinite channel selector. Not the end of the world.
5) Bluetooth is a bit finicky. I can do programming over BT, but sometimes it doesn't want to work for some unknown reasons. I have also yet to find anything bluetooth that works with the radio for listening. Annoying but not a deal killer. I may have to invest in the bluetooth Pelator headset before long.
Long and short, I agree above with WRKC935's assessment. Its a great radio, and a great option.

I too have the SRH320 on my D74

The "license free" stuff is under the ISM (industrial scientific & medical) licensure and is restricted to 1W maximum. All devices must be type accepted, and may have other things like fixed antennas required.
For amateur radio 902-928, same band, but you can do much more stuff. I have some Motorola 900MHz radios I use on amateur that do analog and P25. HT is typically around 3W and mobiles are 30W.
Like UHF, 900 is extremely line of site.

Front end overload is a thing. Unless you have experienced it, and observed it side by side with different radios, you likely won't understand or care. The better radios have much better filtering to prevent this. Also, along side better filters, it also creates better selectivity. Also better accessories are available, and audio quality. These are just a few.

I will also say the programming software is a bit hard to navigate if you are accustom to other programming software. And in truth it's just a pain all around. But once you figure it out, it does it's job.
The programming isn't hard, but there are extra steps vs some of the other things. It almost follows the line of Astro25 Portable/Mobile process, but with a few extra steps. It looks like zone scan is going to be ideal. I did have to figure out the best way to program my zones like I have my other radios, and I'm doing 1 frequency set for 1 "system" for each zone I make.
Anyone know a way to edit the .cv5 files in excel/notepad?

More like it will be expensive I'm guessing as well.
The expensive part is past........
Now I'm looking at building mission plans. Any idea if a frequency can be mixed mode?

RG8x may be a start of your problem. Assuming cable length of 50' (you mentioned the pole is 30'), that 4db loss in the cable vs 1.35db in same length LMR400. Add in the no ground plane on on a mag mount antenna, and you have a severely hampered receiver.
