P110 2ch to 16ch conversion

[NSPD]

I know this topic has been discussed at length, but after lots of searching i'm still a bit confused...

I have two UHF 438-470 Split P110's that are 2ch radios. I want to use them as cheap portables I can take exploring and use with my vehicle repeater that I can bang around and not have to worry about.

Both are Model # P44QLC20A2AA

Serial numbers 188FVJ2389 and 188FVL3002

I would like to convert both of these radios to 16ch GP300's via software so that I can gain MDC1200, QCII, and Scan. Are these radios within the range that can be converted? What steps and software do I need to do it as easily as possible?

Also, since I am 100% new to programming these, I am looking at a Kawamall all-in-one cable since I have had good success with their other cables I have bought. Does a 9V battery have to be connected to the power leads on the cable to be able to program these?

And about the batteries.. has anyone ever disassembled the P110 battery to see where the cells are located inside? I have two Nuon 1200mah Ni-Cd batteries that I would like to drill holes into at the very top to screw in a Kenwood TK-280 belt clip, but I don't want to screw into the cells and cause problems.

Thanks!

On the 16 ch. conversion, no good, date codes after 1993 are not do-able. Yes, you need to provide power to the programming cable to power the radio.

I could understand the hex-editing not working, but writing a totally different GP300 codeplug won't work either?

Your radios will "think" they are 16 channel GP300's, but after Motorola caught on to people "upgrading" their radios they physically removed the channel select lines going to the switch in 2-channel models...it's physically impossible for it to choose a channel above two. If you're just after some extra features & don't want the greater channel capacity, then upgrading could have benefits for you.

Oh well... they're still useful, just in a limited capacity. Thanks Todd.

Now to see if I can drill holes in these batteries without drilling into the battery cells.

Hello:
I have tried to gain DTMF/Phone by upgrading a P110/GP300 that wouldnt give the extra channels because it was newer than the 1993 date.
WAS NOT ABLE TO GAIN THE DTMF/PHONE OPTION.
Didnt try QCII ect .

Not only the channel select lines removed, but you will notice you get repeated channels as well.
1 2 1 2 1 2 Etc....That's due to the channel select lines being 'disabled'.

As for the batteries, they are located almost the entire length of the battery case, except that the lowest portion abdove the two thumb locks, hold a spacer and the cells sit above that, so in practical application, you will have about 1" from the bottom of the case that is bare, aside from the release and spacer, the remainder is filled with betteries( if this makes sense to you).
The release is nothing more than a case-wide piece of plastic that makes up the fingers of that release.....it's a one-piece part and held in by a top plate of plastic.

Above this, inside the case, is the white plastic spacer.

I hope this somewhat useful description helps.
