Wait… you’re sending your 5 & 8 year old (bear snack sized) kids out to scout for bears? Guess you and your wife don’t have to be faster than the bear… just faster than your kids…lol

Good practice suggests using no more power than necessary to establish good communications.
If you can get in to the repeater with only a watt or two I would do that. It keeps the hand held radio cooler and the battery pack will of course last longer.

Nicely done!
You probably want to keep the Power Setting on LOW for Channels 8-14.

Now this is more like it. A big THANK YOU to MichaelLAX, Lscott, Backformore70, and KAF6045 for all your help and input!
Screen shot is attached where I could change the TX / RX frequencies for the GMRS split independently, along with the power settings functions.
I am still looking for the thread where somebody was getting 4.82 watts output, still no luck.

The programming software should have a "download from radio" [otherwise you are always starting from scratch] and a "save file" function (not the "upload to radio").

The software should give you the option to save the radio's setup/memory programming file to disk. That's the file you want to open with the editor.

Aha, that's the problem. Don't you just love getting brain farts? ?

If you look at the screen shot he provided, copied here, you'll see three pairs of frequencies, for three different channels in the editor. He boxed one of the two frequencies, in red, for a pair which he determined was the TX frequency for that particular memory channel. Since initially both RX and TX were set the same that's why they look like a duplicate of  single frequency, but in reality they are the discrete RX and TX settings.
This radio does not use a firmware that assumes a single frequency with an offset model, typical for some Ham Radio gear. It REQUIRES two distinct frequencies, one RX, and one TX, for each memory channel. This is common for many many radios, particularly for commercial models and their derivatives. Having hack a number of Kenwood radio specific codes plugs myself I've seen the same thing using a hex editor.

Yeah, if you look closely at his screen shot of the editor you will see several pairs of frequencies, one pair for each programmed channel. All he did was pick the second of the two in a pair, the one he wanted to alter, and changed it from 462.xxxxx to 467.xxxxx to get the repeater input frequency.
The only down side to hacking code plugs like this is when you need to make a change to the frequency. If it's one of the hacked custom frequencies you're back using the editor again. Not real convenient but it works.
Not all radio's code plugs are this simple to hack. A few use various types of encryption to try and prevent this sort of thing. I figured that out on some of the Kenwood radios I have. After decrypting the code plugs a few interesting items were found like model numbers, embedded radio serial numbers, programming software license install keys etc. I was also able to see the normally hidden radio write protect password, if used in the software, in the clear.

Yes, @KAF6045's comment to me was in response to my comment to @wrtq652's comment about the Radioddity DB-20G (a palm sized mini-mobile), which does cover both VHF and UHF.

I saw that page, but it is for MacOS. Since I'm using Windows 8.1 I had to download Bluestacks and then find the Windows version of Hexfiend, then open it through Bluestacks. The Mac version won't work
I did edit the only set of frequencies I found in the T11 software (using Hex-Works) which put the new frequencies in both the TX and RX ?
This may take some time.

Take a look at these items in the Code Plug Hex file (through Hex Fiend) for channels 7 & 8 and 14 & 15, where it goes from High power, to Low and then Low to High:
It goes from 1 1 1 0 to 0 0 1 0; so perhaps one or both of those leading 1's are part of the HIGH power designation.
Oh, but wait, the Programming Software for the T11 already has the HIGH setting for all channels except for 8-14, which are LOW (see my screenshots posted on September 10th).
So maybe some other designator is needed to provide SUPER-HIGH power.

I tried to find Hex Fiend and it seems it is no longer available   However, I will have a look at Hex-Works possibly over the weekend if I get time.
Trying to locate the power setting could be challenging but that will be after I get the frequency fields changed successfully.

I could see a pretty cool use case in which a Retevis RT97 repeater is used for a campsite (or a church), and a bunch of little BF-T11 satellites for the users 

SUCCESS!!!
This software creates code plugs that are unencoded XML.
I used my HEX editor to change the TRANSMIT frequency on Channel 19 to the INPUT frequency for Repeater Channel 19R and used the BF-T11 software to enter the ENCODE CTCSS tone and now I have confirmed at home that these handy little units can transmit and receive on the 5 MHz split!
Now 2 watts is not enough for me to actually access my local repeater from inside my home, but later today when I go driving closer to this repeater, I will confirm that this will actually allow me access to this 650 Repeater:
 

FYI, same here. Not seeing any repeaters on the map at all and the search page generates an error message for all searches.

That's how they found a number of the 1/6 protesters. Their cell phones got pinged of the local cell towers. The Fed's got the info from the wireless carries.

I had bought a pair of Hustler MRMBNC mag mount mobile scanner antennas months ago for my scanners, but since I was moving soon I never did anything with them. Well, I unpacked them the other day and decided to try hooking them up to my Antenna Analyzer today and see what turned up.
 
They actually did quite amazingly well on GMRS, especially on the repeater transmit frequencies. My SWR readings were in a tight range of 1.06:1 to 1.09:1 and this was without any tuning. The results were a very pleasant surprise because I thought they would have been in the barely acceptable range and would need some serious tuning, but evidently I don't need to do a thing.
 
For those who don't want a permanent install (like me) this may be a very viable and cost effective option. When I bought these, it was a pair in one auction which I won for around $18.00 +5.50 shipping. I see they are going for about $22 each on various sites around the internet, and the ones on ebay are sky-high at the moment. You will probably need an adapter from a BNC connector to whatever type connector is on your radio.
 
I have a Radio Shack scanner antenna around here somewhere and will have to check that one out next when I find it.
