[Motorola] HT1250 PROGRAMMING

[Eric Lemmon]

Dan,

According to the Motorola catalog, all models of HT1250-family radios with
model numbers ending in "5" were shipped with limited keypads.  It is a
fairly straightforward task to retrofit a limited-keypad radio with a full
keypad case.  When the proper case-opening tool 6680702Z01 is used, there
will be no evidence of the modification- other than the model number
mismatch.  I have not performed such a retrofit myself, but I have performed
many case replacements (cosmetic kit installations) on such radios, and they
bear absolutely no scratches or pry marks.

Just so we're not comparing apples and oranges, when you use the phrase
"generate DTMF" do you mean manually creating DTMF tones from the keypad, or
do you mean causing a DTMF radio identification code to be automatically
transmitted every time you press the PTT button?

Yes, ther LS+ has a full keypad radio, as did the plain LS. I'm of the 
belief both are factory original, and not modified, but can't say with 100% 
certainty. Neither had any pry marks on the case or other obvious signs of 
being opened/switched.

I no longer have the other radio, a HT1250-LS (altho I still have a copy of 
its codeplug), and it, too, was a full keypad radio, which I also believe 
was factory original. Its nomeclature is H25RDH9DU5. As mentioned before, it

programmed fine, and waking up DMF was no problem...once the CPS items were 
set up, it generated DTMF during PTT just like you'd expect.
