[Motorola] HT1250 PROGRAMMING

Thu Nov 6 21:17:26 EST 2008

Hi Eric...

I appreciate your comments, and also just posted another email about 
changing programming fields in the problem radio.

To be clear, what I am trying to do is get the radio to generate manual DTMF 
tones from the keypad (just like in the old days), has nothing to do with 
ID, paging , selective signalling, etc. Just transmit DTMF over the air when 
PTT is depressed, also give the user an audible DTMF sidetone 
simulatneously.

I got a number of these radios some years back, and based on your comments, 
apparently one or more had been modified, despite looking new and operating 
just fine. If this is the case, then the problem radio's full keypad needs 
to be interfaced with the logic board, as you stated earlier.

Do you know where I can find info on the retrofit you mention? I've looked 
thru  the BATLABS site but couldn't find anything.

Thanks and 73
Dan
