Some MODAT info found in an odd place.

I dug up an old Bendix/King UCOM disk tonight. For those who aren't familiar a UCOM is a Universal Communications Options Module add on board made for the King EPH series hand held radios. It's basically a super capable multi signalling options board. I noticed a file called MODAT. I selected the MODAT programming option and found a list of what appears to be the MODAT signalling tones arranged by their numerical value 0 through 9.

I though this may be of some interest to some MODAT fans here. It may even by common knowledge but I've never seen a list of the actual tones until now:

Does this appear to be in the range of what may be used for the tones? I copied it from the software.

0= 0637
1= 0787
2= 0937
3= 1087
4= 1237
5= 1387
6= 1537
7= 1687
8= 1837
9= 1987


For those who may be interested the file is in the yahoo group BKradio files section and is called UCOM.

As most of you are familiar or not, MODAT was designed for cement mixer trucks. As a way to control and check on the mix as it was sent on it's way to a site for delivery.

i know Suzio York hill has a funny lookin . boxs i never have listend to them they are on Low band and i know it is not mdc1200 with 100watt radios

they could be (gasp) speed call boxes sounds like DTMF or the could be running Dinets (white box about 6" x 8" with stat us buttons) dinets use FSK data for status & PTT ID not quite the same as MDC 1200 but can be mistaken for that by the casual listener JD

i need to load thee freq into my scanner and give a listen

[10-95]

So the BK'S could actually do Modat signalling with an options board??

Wonder how much they had to pay M for the right to do that?

Yea, I guess so. I would like to get a UCOM and try it out just for s**ts and giggles but they kind of hard to find.


I bet it wasn't their best investment.

I have tried both the Bendix King and the Transcript Intl MODAT modules. They sounded somewhat similar to the real McCoy, but yet not exactly the same. Also, neither of them would work with my MODAT terminal. You can find the exact MODAT frequency tones, durations and spacing times for MODAT in the Micor MODAT manual. This info can also be found in the MODAT Systems90 box manual.
