I-Call: New Experience

[whacker]

I just this week had my first ever reception of an I-Call on MPSCS. Normally where I live, listening to the Sumnerville Tower, I've never picked one up, and only within the past six months did I have the proper programming in my 396T to allow it (thanks to RR).

But my job takes me all over, usually in Indiana, although this day I had some service calls in Michigan. I was sitting in the parking lot of the McDonald's in White Pigeon (across the street from the MSP), checking out the Jones tower, when all of a sudden I heard a transmission, and looked at the display and saw something like this: "ID: 714xxx - 714xxx". I quickly realized the leading "7" meant it was an I-Call, and I assume the remaining five are a specific TG or individual ID for the unit.

I know TGs that start with "14" are not typically MSP units from that post (White Pigeon), so if anyone can enlighten me as to the general thing I was hearing, please chime in. I didn't listen long enough to catch the gist of the conversation. I suppose it could be anybody else using the MPSCS.

Also, when you catch one of these, are you hearing the car-to-car from the tower repeater, or are you hearing it straight from the cars, like conventional radio?

Thanks for any info.

7 is just a Uniden thing - the rest of it is the actual radio ID. If both radios are affiliated with the tower you are listening too, you'll hear both sides. Otherwise you only hear one.

Those aren't talkgroups, you're comparing apples and bananas. They could be MSP from that post. Or anyone else.
