Seems to be alot of ASK MTS2000's showing up on brokenstolenradios.com aka Ebay.
Here is what I have found works. First, I take no responsibility if it doesn't work.
You will need a copy of MTSX DOS RSS version 2.00.01 (NOT lab or depot, plain regular 1993 era MTSX DOS RSS). DO NOT USE ANY VERSION OF LAB/DEPOT to do this or YOU WILL KILL YOUR RADIO and end up with the dreaded FAIL 01/93 toolproof error. You have been warned.
You will also need a REAL MS-DOS based O/S and machine to run it on. Forget trying to run it under any version of Windows, you can risk bricking the radio trying to read/write it in a DOS box. Time to break out the old school laptop you have laying around.
For some reason, this ancient version WILL read a modern MTS2000 just fine, and ignore the ASK flag in the codeplug. Read your ASK'ed MTS2000 with it, save the codeplug. Write it to the radio.
Then go to your MTS2000 CPS R02.03 machine, read the radio as normal. You will not get the pesky "cannot write to radio without Advanced System Key message". It's that simple.
I have done this with multiple MTS2000's and had 100 percent success. All of the MTS radios I have done this on had F/W versions of 6.11 to 8.73. Various flashcodes/feature sets.
My best guess is the old old version of MTSX DOS RSS does not "recognize" both the ASK flag or the last written to with CPS version number and ignores it. It shows you the codeplug structure hasn't changed that much either, as it's able to read and unpack the codeplug just fine.
Hope this helps.
