MPD help cant get DTMF to work

Post by n9llo »

This is driving me nuts. I took a good 16 plus 800 front controller and mated it up with a VHF RF board. I got everything working except I cant figure out how to make this thing do keypad DTMF dialing.

Chris,

Do you mean by pressing a DTMF key and having the radio send the tones as you press the keys ?

If so the radio does not work this way, you can either enter a fixed phone list in the programming software then use the Memory location of the desired number and do a FNC-RCL-N (where N is 0 thru 9 corresponding to the phone numbers memory location) to bring the number up from memory then you need to do a FNC-SEND to send the tones.

A 2nd method is to key in the phone number from the keypad and then you must press FNC-SEND and the tones are sent out.

When you do this the LCD display will show the numbers entered, if you make a mistake with the number you need to enter FNC-CLR to clear the mistaken entry from the display and enter in the correct phone number.

I hope this is what you were looking for.

Mike,
The second one I put together the same way operates like this.
punch some digits on the pad than hit PTT to send them out. I think the
label on that controller said copyright 1988. I think the other one said 1986 so mabey it's a software issue, thay both have the same codedplug. I am going to see if I have a nother '88 controller and see what happens.

Chris,

It must be unique to the 16 plus controller board as all mine are standard MPD conventional boards that were from UHF and 800 radios.


Do the 16 plus controllers have the little scan/DTMF daughter board that plugs into the main controller.

Well I got the other one to work. The last thing I did was zero out
the old talkaround tracking data that was still in there. Then it started working. I suppose I did something wrong in the first place to still have this info in there.

I did somthing like that as well and really botched it up, actualy my once MPD 16 plus went from UHF to picking up mysteriously 800 freqs from 50 miles away. I guess you never know when amatuer radio techs go at it.. Actualy does anybody knowhow this is even possible, becuse with my knowledge i dont think it is.??????????
