You might find radio mobile online a useful tool; it'll let you map expected propagation based on topography, vegetation, and built up areas. It does point-to-point link calcs as well as general propagation. It's free for ham and GMRS frequencies: https://www.ve2dbe.com/rmonline_s.asp
The trick to getting accurate results is to turn the required reliability up to about the 90-95% range.
Made my own up, areas we have tested, there is a few ridges to the South east as far as 35 miles away can hit my repeater from.
Surprises my jeep buddies they are 40 miles away and hear me answer them... At least the ones with better Midlands,
I keep telling them forget Midland, even when I used CB's still I never liked Midland.https://mygmrs.com/repeater/4252

Mrs just left work,
You can see my issues with terrain and line of sight.
Antenna is on a 50' pole, so at about 480' elevation, but just mile to the south is HorseShoe Mtn,
500 to 550', I need that antenna up another 50' minimum to reach the city.
We've learned where we can get a good signal.
Mrs was able to reach the Repeater from down there at work for a bit then the shadow of the ridge got her.
Not bad for the TK-880 I just installed in her Jeep.
Get on a ridge it does reach 40 or 50 miles to South, East, West.
North is the Ozarks and everything gets higher from here.

If you look for the international version of CE you will be allowed to open up to wideband.
THe software link Blue on ebay sent me was the export version of the software I think..
Not a bid deal, since mines stuck to using one channel.
Son wants to use it as it is, programmed to the repeater.
Other option just save it for a second repeater build later if I can find a location for it
down around town. Not had much luck on that yet. -

I purchased my Kenwood USB cables from bluemax49ers on eBay. If you send him a request immediately after purchasing, he’ll email you the link for the free software download and all for approximately $20. You can’t go wrong.
I ordered two cables from him, and I got the software.
Thanks. -
WEll got a data cable, software, reprogrammed a few channels into it, and still nothing.
So its programmed for the Repeater. Maybe later if I build a new repeater it will become the 50w xmitter for it.
On the plus side, I have stuff to program the things so don't have to be as scared of them..
It does not like programming Wide Band, says that is illegal, when its not.
Crazy Motorola... -
Whoop...
Success.
Data cable came in today.
Using Linux, and Dosbox, usb cable I got the TK-880 programmed.
For whatever reason Wine ran the windows software a couple times
then crapped out and error crashes...
Even working with my repeater.
KPG-49D_v6.30 (DOS) gripped about the age of the radio firmware a bit.
Couldn't program a home channel, kinda disappointing, Its going in the
wifes Jeep. Wanted that,
Still have to figure out how if possible to save a couple channels to the
A/B buttons.
No reason for groups, so that is now the channel up/down.
25w radio putting out 18w on high, and 4w on low.
Now to find Vertex software...

Leixen 898 is not a clone of TK-880, not even close. Radios are totally unrelated. Cable might work, though. The software is KPG-49d, as mentioned already in this thread, versions 4.x are for Windows, work just fine in Win10 X64 with USB-to-serial adapter. I have 4.02.
Well it has to be a data cable issue.
Off to fleabay and order, one, actually I need two,
One for the TK880, and another for the Vertex 2200Get all these radios working, may sell a couple. Hadn't decided yet that far ahead..

same case, same buttons, same size, just the Lexien has smaller heat sink, and Lexien uses Kenwood mic pinout.

So, KPG-49D Version 4.21 is what I have and it is Windows. See if you can download the file I've attached. MODs, if this is forbidden, my apologies up front.

can't use it without a serial...

The old DOS software likely will only work with a REAL RS-232 port using the 16550 chip.
https://en.wikipedia.org/wiki/16550_UART
DOS software typically programed the ports and other hardware directly. If the real physical chip register doesn’t exist then the software fails. The usual USB to RS-232 emulation cables work only because the software uses the drivers Windows installed. The drivers don’t emulate the physical serial chips.
One other problem with DOS software is the speed of the computer. Timing routines were implemented in software so a computer that runs too fast also will cause problems. Experienced radio technicians are known to keep old slow DOS computers around with real serial port hardware to program old radios when necessary.
Linux is more advanced than ion that regards, and Dosbox has the emulation of a RS232 in the system, so just add config to the port.
I can't verify the chinese clone of the TK780/880 doesn't have data lines reversed etc. So just get a correct cable. Not like its much money.
Once feature turned on, panel programming, snip a resistor it can all be done from the front anyway..
Thanks, sad part is very few computers in the last decade even have a real serial port anymore. -

The software is free. Get version KPG-49d v 6.30.

I found it, its dos based, what I was trying, it doesn't like the data cable I got I think,
Kenwood mics work on the Lexien 898, so not sure whats up with the data cable/software not liking it.
Unless the software looks for/id's the cable which it can't do via dosbox I don't think... -

I didn't get GMRS for the social aspect. Repeaters are sparse to non-existent in my area anyway. I got a pair of KG-805Gs so we would have more power from the radio and replaceable antennas for better range. (Getting up to 4 miles with the Nagoyas.) Basically beefy walkie-talkies, which is really all GMRS is in reality. My son and his mom have zero intention of ever getting a Ham cert so the KG-805Gs serve us well for family outings when we want to split up.
Do not underestimate UHF and 8 watts.
70cm Ham repeater I have hit 80 miles away, its on top of a mountain in Little rock.
I use regularly with my HT from house at 40 miles.I've compared 10w, GMRs and 50w, other than a bit more modulation carrying over the ridges to the repeater, not much difference.
If you find a location on a hill, can have two antennas on the same mast 30' apart vertically and build a repeater system from cheap commercial radios without the need for a duplexer, and be surprised how far your 50w will go.
I've heard guys in the Oauchita Mountains on cheap midlands 50 miles away. -

Sounds like it worked really well, that's for sure. No doubt an antenna outside the aircraft will help a ton. Keep up the good work youngster. I miss the good old days (which lasted for more than a decade) I was doing it.
When needed one of our HAM club members has a repeater in his plane, talk about range, having a 20k foot repeater tower.
Talk to other states..... -
I'd sworn these could be programmed with Chirp...
Well NOPE.
The Lexien 898 was a clone of the TK780/880 so I had a programming cable.
Hoped it would work, well I run Linux, so with Dosbox, and the dos software,
Hoped I'd luck out, no dice. Once set and a resister removed can be programmed
from the front.
Guess I'll be ordering the proper cable and maybe if I can find it without breaking,
the bank, purchase the software....
Destined to be GMRS radios...
TK880-1 UHF 25w.

I'd like to just change the user name... :/

Daystar sells this little console.
Also sell a TYT TH-8600 as a GMRS, not sure its a legal conversion, mine is Ham, dual band.I didn't wire anything to the switches, as I don't have any extra anything to wire up.Don't even have fog lights.The TH-8600 was my choice because its advertised at IP68 waterproof, and I spend all summer in Bikini top so I do get wet on our random thunderstorms.Antenna sits on a bracket I made attached to the third brake light, Tram dual band. It has a flat SWR on 2m, Murs, 70cm and GMRS.

Congrats,
I use to be admin of FB Arkansas Jeeps till FB banned me.
I was a big on GMRS for Jeep rides, so much nicer than CB's no interference, even suggested HAM too, for emergency, at least one person.
Be surprised what 2M Repeaters you can hit, if you have an emergency.
Locally my area not many people use GMRS for around town.
Local Jail uses it, lol, talking between cell blocks.
I made a mount for a magnet mount antenna attached to the third brake light.
-
The county Jail uses GMRS 20, 462.675 between floors, I hear them almost daily leaving work.
I think there is only about a half dozen GMRS users in the whole county.
I do occasionally here someone (unlicensed) bounce off the repeater.
Then there is a few kids with GMRS radios around, though never hit the repeater.
Those that do find the repeater, I invite them to get a license.
99% of the time no one ever uses it. Just our family. -

I think it's probable it's either the key lock enabled (try pressing and holding the front panel keys one at a time and see if that resolves it) or someone goofed the programming and disabled the front panel keys (I want to say it's just a drop down in one of the screens)
If it comes to programming, Bluemax49ers cables have worked well for my vertex stuff, though he didn't have one available for my vx4200; you can get the software from him as well (All the vertex stuff I've seen was free).the cables are also pretty reasonably priced as well.
Okay gave it a try.
Holding P1 does make it say Lock,
P2, P3 no descernable function turning on.
P4 makes every LED segment come on on the screen, then freezes, have to remove power to reset it.
So back to wondering if somehow it had all its memory wiped...
May look at getting a cable and try reprogramming it,
-
I just ordered three TK880 commercial radios.
WQas about $100 for all three, 25 watts.The positive side is Commercial radios are built like tanks.
So they will be programmed for GMRS and a few repeaters.
My Repeater is a Kenwood TK720R I think it is,
I love the sound of it. PErfect modulation, and
great reception....
So just a thought, if you're looking at a mobile setup.

Can you use the software with cable to change it...?
maybe if had the cable setup, but not sure I want to spend $$$ and not be able to fix it.
I only need 462.675 simplex, and same for my Repeater. Thought about it, but would have to be set
for the Repeater or Simplex.
Wonder what the odds are it lost its programming, so only got the one channel programmed.... Just thought of that... -
GMRS/UHF do not skimp on COAX.
Especially if running a long run for a tower,
My Repeater on LMR400, about 100' though only using 50 of it atm.
You need the highest DB gain you can get to get weak signals through
the Duplexer in the repeater.
My Base setup (before I learned about db loss in coax.)
Tram Dual band 1481 I think it is. just RG58 50'.
I can't begin to hear signals the repeater can.
Its antenna is similar, but Diamond X301 I think it was,
picked it up from a HAM meet.
Both have SWR 1.1
So if someone offers you free Coax, and its not deigned
for UHF/GMRS sell it to some CB'er and invest in the good stuff.I got a roll of brand new 1/2" hard line for free from a fellow
that climbs towers for a living......- WRPS249 and AdmiralCochrane

My repeater antenna 50' in the air at 452' where its planted. So 500 at to the top.
The kicker to the south of me is a Ridge thats 550' with 60' trees on top of it.Dead south to south east over that ridge is terrible. With a 50w radio it gets enough signal scatter to hit the repeater out to 10 miles.
But to the west/south west it can talk 25 miles. Ridge tops 50 to 60 miles.
GMRS in some places seems to fold over the hills between here and Conway.
There is places in town you can hit the repeater but very few because so many ridges.Over 200' tower, you need a light, and get approval from the FAA.
Then a simple pole is not likely to make it that high.
I'm using heavy top rail for Chainlink fence, and at 50' its a real challenge.
I got all the hardware 1/2" hardline, etc, I could goto 100' even the extra pipe.Now getting it up there is the issue, and can't find an affordable lift to rent.
In a few weeks I get some more cable, may try to ginpole a 125' up,
using the guy cables. Ruined a few poles trying in the past.
I really want to be able to hit the freeway and the city south of me at 15 miles. -
I got one was sold by Rugged Radios. Programmed for GMRS, 50w.
The down side it wan't change channels none of the buttons work.
It works, at least on channel 1.Any ideas/suggestions?

Many HAM's have GMRS too,
Thats the sad part you need two radios to be GMRS legal,
Though many China radios gladly work on HAM 70 cm and GMRS,
Most of them don't put out enough power to be illegal.
My Anytone, says 25w, but in reality on UHF its about 10w.
Same for the other TYT, Bajoie, Leixen, 15W at the most.
QYT makes one thats 75W, UHF, and B-Tech sells it as a
GMRS legal radio, I'm sure they detuned it.
Mean while the QYT 890Plus says 50w UHF.
Where imo if a person is licensed for both, you obviously
will be versed in how to setup your radio to be in spec
for GMRS....
That said I often wondered WTF would the FCC chase down
a lowly Jeeper etc using GMRS at 10w or so, when there is the
stations on the CB that you know are bushing 1000w or more.
Literally talk ground plane for hundreds of miles. They would
be easy to chase down.
One thing I will say if you interfere with HAM 2m/70cm they live
to get out a directional yagi and go looking for you....
