I have the 878+, from what I understand, the only difference is number of channels and number of contacts. I know it's controversial, but nobody needs the entire DMR-ID database in their radio. I stopped using the contact list all together, with the exception of 5 individuals.

Gland you are enjoying it. For the money, it does appear on paper to check all the boxes. I was not impressed with the analog capability, and often experienced front end overload. It was even replaced by bridgecom with no improvement. Digital monitor mode is more of a gimmick feature, not that it doesn't work, but I never had the need for it. I've always felt if you need that feature, you didn't do your recon work before hand. It also doesn't do proper DMR roaming, which both Kenwood and Motorola do very very well. I too spent too much recently, but I'm going to end up spending a bit more this weekend, hopefully to finish this permeant repeater install at the house.

I suppose GMRS could be used for community events, but I don't see it happening around here. A ham friend nearby has the local neighborhood watch on GMRS, and they do talk to each other all the time.

Why? I'm half and half on DMR for GMRS, but when you sit down and think about it, DMR would allow for better co-use of a single repeater pair, with the added bonus of better coverage and other tools that quite frankly would be used in our house.

I think the ID-O-Matic doe that.

This is probably a good idea to start out. The XTS/XTL are excellent radios, but the are end of life, and you can really confuse yourself finding the exact model you need with the correct flashcode (Motorola code for features enabled). The nice thing about the XTS/XTL, you can set an entire zone for the GMRS frequencies, and enable MPL (or user selectable tone) which will allow you to change it on the fly, but you have to program each possible PL for RX & TX, and name it appropriately. It does cap out at 60 pairs.

That makes sense. Yes, on the APX line they do have multibands. You will likely spend your entire $2500 budget. Fortunately, the APX CPS is free now, and you are able to get wideband entitlements from Motorola.

Moto XPR7550 does not come in dual band, but you can get both VHF and UHF. Kenwood NX-5700/5800 is similar, one deck for each band, but you can stack the decks into a single head. A dad mount (not remote mount, single deck) is about $900 new. Remote kit is about $350/450. Should be right at your $2500 for UHF + VHF with analog and NXDN. FPP is $130/deck. Caveat on the IHF is any FPP reverts to narrow band, but the VHF supposedly doesn't. I'm on the waiting list for a 5800K2 that should be coming soon. You can do OST (operator selectable tone) and setup a table of 40 options. You could add DMD or P25 to each deck as well, P25 is the most expensive entitlement though.

It is not a broad term: 47 CFR 95.303 “Remote control” Operation of a Personal Radio Services station from a location that is not in the immediate vicinity of the transmitter. Operation of a Personal Radio Services station from any location on the premises, vehicle or craft where the transmitter is located is not considered to be remote control.

I have no idea if you can repair or work on the chinese stuff. PacParts has Kenwood stuff and Motorola sells direct, if it is still available.

JPoles are not omni-directional, they have a deep null and some gain in the other axis. https://www.w8ji.com/end-fed_vertical.htm

I didn't say it would keep you out of trouble, but they are the only two scenarios that I can think of that I would present any of my licenses.

The only reasons I could see one needing to produce an FCC license are as follows: 1) one of the states that requires an amateur radio license for possession of a scanner. Again, this exemption is only for amateur radio, not GMRS. 2) in a state where hands free communication laws are in place, though most of these laws apply to texting/internet and/or have exemptions for two way radio/amateur radio.

I think the VX7R does, I know it will transmit 1W AM in 6m.

Yaseu FTM-400 will receive AM airband. I use it quite a bit more than I thought when I'm around the airports. Kenwood D-74, Yaesu FT5D, Icom ID-52 , Yaesu FT60, Yaesu FT70, Yaesu VX6R, and those are just a few of the amateur radios that can receive. Yaesu/Vertex Standard make actual airband radios you could look at as well.

I wouldn't say negligible, 2.7 vs 3.3 db/100ft at 450MHz is something. It gets worse going up, 3.9 vs 4.7 at 894MHz. I have a lot of 400MAX in use right now, but the repeater is going up on 1-1/4 hardline, and I'm in the process of swapping many things over to hardline.

For what it's worth, DX Engineering's 400MAX cable has the same properties as Times Microwave LMR-400UF.

Problem with P25, is you can only get very narrow equivalency if you go trunking (Phase II), where as DMR does it 100% of the time, and NXDN can run two separate repeaters side by side in the same bandwidth as a single P25 or DMR repeater.

Any further progress on this? I'm interested to hear if you do end up getting it to work as more than a 2 channel radio.

I agree, it will be one of the big 3 (DMR, NXDN or P25). If you get to listen to the big three setup correctly side by side, there isn't much of a difference. DMR being flooded with bad IP links, barely operational hotspots, and cheap radios does affect how it sounds. Local via repeater, on Motorola/Kenwood equipment only, you can't really tell the difference between the 3. P25 phase 2 does sound different, but that would never show up in GMRS, because that's a trunking only protocol.

I had to pull the sticker off from around the contacts on one, and used a cloth and rubbing alcohol to make it work. One of the contacts was pretty green.

Why compromise and select 1. Sure, getting everything costs more, but in my experience, its worth it. You also forgot selectivity/sensitivity, which is hugely important. Don't forgot availability of support locally. That's not even starting a discussion about uses beyond GMRS, which may or may not be important to others.

What does the radio do when you go to channel 3?

I'm interested in this project. This seems the same process as getting on 902MHz for ham. I would bet GMRS wouldn't be a problem, firmware probably isn't smart enough to block that out completely. Getting down to 440MHz might prove difficult. I do wonder where the hard stop is at the bottom.

Did you download the specific driver from bluemax49er? Also, you may need to change the com port number, usually between 0 and 3, and select the appropriate port number in the CE27.
