The O'Fallon Missouri Police have switched to using digital. While there are problems with listining to them with the scanner. I am told that the officers are hearing dispatch loud and clear.

If I recall when systems are doing simulcast there is a problem hearing them over a scanner if I recall.

Regarding O’Fallon PD going digital. I live in O’Fallon and have a Pro 96 digital and listen to them all the time and did not notice the change over. If they are digital it sounds totally different that the St. Charles S. O.

Do you ever hear a medium to high pitched tone while listening to the S.O.? Every once in a while I'll pick it up on my 396. I dont know if its just an artifact or an actual tone thats being sent out.

In regards to high pitched tone from the S.O. there is a CW ID followed by a tone that can last for several minutes and sometimes a poor signal voice distortion. I do not hear a high pitched tone.

I do not know how you can not hear a difference. They are no longer on the 854.6625. See the radio reference page for st. charles county / O'Fallon for the latest frequencies.

I am not having any problem receiving the new freq and no chopping. I did hear an echo on one officer and he said he was having problems with interference from other signals maybe from several sites transmitting at one time or a delay in the system.

So far so good with the new system.

Good Luck

This is a Motorola trunked system, try programming it in as that. The freq you posted as the Police freq is actually one of the voice channels. 770.75625 is the primary control channel and the rest are voice channels. The TG ID for the PD dispatch is 10701.

I have submitted this to the DB admins to add to the database.

What setting are you using to get them on your Pro-96? I can't get it to come through mine, can you send me the .p96 file on it?

Sorry - Pro96 will not trunk 700 Mhz. It will pick up these freqs conventionally. You have to get a scanner newer than the 96 which does P25. Wow! A 700 Mhz TRS in the land dominated by VHF... (Left STL late 70's - great scanning back then.).

I misunderstood the other message to say he WAS picking it up on his Pro-96, that is why I ask, I was under the impression that it couldn't be done, but thought he may have found a loop hole.

I don't know about the trunk part but I do receive OPD on 770.50625 with my PRO 96. So far all coms are on the same frq. What radio will work for 700 mhz trunking? And then is it worth the cost to listen to them and what will I miss if I don't buy a new rig.
