I-Call vs. Private Call

[ceranes]

Are I-Calls and Private Calls the same thing on the APCO-25 system?

I calls are for EDACS, or that is what the makers of EDACS calls it.

Motorola calls their i- calls by a different name or vice versa private calls. Private calls are on apco 25 because it is Motorola, But they are basically the same thing.

Be careful just how you ask this question. Private calls don't have to be just on Motorola equipment. They are by no means just on what you termed "APCO 25" communications.

Privat calls are placed between just 2 individual radios. The rst of the talk group that both radios belong to in a trunking system will not hear the conversation. Yes the conversation can be monitored by a scanner as long as the transmissions are not encrypted. You can have private calls on both an analog and digital radio trunking system.

As for the refference to "APCO 25", this is only the format the trunking system is using. There are not that many true "APCO 25" systems on the air at this time. To have a true "APCO 25" system, you need to have the 9600 baud control channel. If you have the 3600 baud rate control channel, your more than likely only an "APCO 16" compliant system. It is also probably a proprietary signaling format that is non compatible with other brands of radios.

Only the 9600 baud control channel speed allows the true compatibility with different equipment makers. This now allows Motorola, MA-COM, E.F. Johnson and others to all play together on the same trunking system. Most of the digital features are now available to all the different brand radios.

The new year in 2006 should be a major step towards interoperability around the country as agency systems are upgraded to digital. The down side of the improvement is that all the older analog user and base station equipment will have to be replaced. There is no longer the ability to operate in the analog mode after the switch to a 9600 baud "APCO 25" system. The user radios will have the ability to do analog, but not on the trunking system with the 9600 baud control channel.

According to the manual that comes with the Uniden BC796D, both Motorola Type-1, and Type-2 systems support I-CALL. They don't make any mention of it being refered to as something else.

Im not able to pick up any of the Harrison Twp fire traffic on the known listed analog frequencies for Harrison Twp. And I have yet to pick up any new fire talkgroups on the MPSCS. Does anyone have the frequencies? I would assume all dispatching comes from the county but havent heard anything on the county fire nets for harrison. Thanks.

I've only heard Harrison a couple of times. I've heard most of the FD's that have gone to MPSCS, just heard BRUCE.

Try 154.2800mhz HTFD has not gone to the MPSCS yet!! They are still on the conventional freqs. They however use 154.28 as their own freq. They do have plans to migrate with the rest of the county in 2007

In the Traverse City area here. I sometimes hear an MSP dispatcher ask if she can private call a trooper, but I never hear the traffic. That was on the Pro-96. Just picked up a 296D, but haven't really listened to the MPSCS with it yet. Should I be able to hear the private call?

No, only the 396T gets APCO P25 I-Calls.

Brian, please don't hijack threads. Create your own topic. Thanks.

I have a new Uniden 796D and have programmed all the Connecticut State Police frequencies, talk groups, and set the unit for control channel only operation. I seem to hear everything as far as dispatches, car to car chat, etc. I have been recently hearing troopers requesting HQ to contact them on a "private call" on their portables. What does private call mean? I don't seem to be hearing the private call transmissions...

Geez, do ANY of you newbies read the threads before you post?

Ryan, go read the Wiki on trunking or do a search for more information on private calls. Do NOT hijack threads (AS I SAID ABOVE).
