[Scan-DC] Analog Virginia State Police transmission on 700 MHz

[Andrew Clegg]

John, Dewey,

Unfortunately, the 996T does not appear to save the 10 auto-stored
close-call hits when the scanner is turned off, so I cannot retrieve the
frequency.

Also, I played a little with the digital reception tonight. I am using
D.C.'s 460.375 MHz channel for tests. I can get it to decode P25 if I
program this frequency as a channel and specifically tell it that it is
digital, but in search mode, I can't get the radio to automatically decode
digital when it stops on this P25 channel, like my PRO-96 can do. So now I
wonder if the 996T does in fact automatically decode digital in Close Call
mode? If not, then that VSP transmission probably was analog after all!

Although the 996T manual is very long, it seems to be short on details of
exactly when it decodes digital. If anyone knows how to make the radio
automatically detect and decode digital in search (or Close Call) mode, I
would be most appreciative to know. I have looked through the menus very
thoroughly and haven't found this option. Perhaps this latter discussion is
better suited for the Yahoo 996T group...sorry for the babble.

Cheers,
Andy

  Remember close call is just that.  The 996T feature is impressively
accurate.  A guy in Chesapeake got a close call mobile on the Div5 764 mhz.
frequency when passing a VSP unit and the frequency was only 5 khz. off from
the exact frequency..

Thanks John and Dewey. The sum of both explanations seems like a reasonable
explanation for the mystery.

If the hit is still in my auto-stored Close Call group, I can look up the
exact frequency. I'll turn on the scanner later today and see if it's still
there.

  As others have posted you probably heard the digital mobile repeater
signal as the 996T will decode P25 signals and in my opinion, the
digital audio is superior.

Hi Andy,

Just out of curiosity, were you able to confirm that it was analog FM?
Close call automatically decodes digital for me, and I've heard some
transmissions that were so good, that I couldn't tell that they were

digital

if I hadn't already known.

For my birthday last week, my XYL got me a Bearcat 996T for the car. Over
the weekend, I took a very long (20 hour) car trip and got to play with the
996T quite a bit in analog mode (I haven't tackled digital yet). It is an
amazing piece of hardware.

Late last night (Monday night), I was driving back to DC out on I-66, and
passed what I believe was a VSP officer on a motorist assist, on the
shoulder. Just as I passed, my close-call fired up, and tuned into the
officer reporting the assist, in analog FM voice on a 764 MHz frequency.
While I am aware that public safety is moving a lot of their operations to
700 MHz, I was very surprised to hear analog on the very new channels. RR
reports this frequency as part of the VSP APCO 25 system, but I would have
thought it would have been digital from the get-go. Is anyone on Scan-DC
able to provide some background on the VSP's use of 700 MHz?

Thanks!
Andy
