According to the FCC Search page at
http://wireless2.fcc.gov/UlsApp/UlsS...chAdvanced.jsp
both freqs are Fed Ex, which has a huge operation in Memphis.
Current Uniden and RS trunktrackers are capable of following most
trunked systems on 800 MHz. with only the data channel known, the voice
channels will be deciphered by the radio.
You can also use older non trunking scanners with a program called
Trunker, this deciphers the control channel and can even send a second
scanner to the voice channel. This does require a discriminator tap on
the "Data" radio and a computer control feature on the "Voice" radio.

hello all.
I'm pretty new to this newsgroup but I've been casually using scanners
for many years. I recently obtained a BC895XLT and I like it a lot.
Here's my question.
While searching, I've found some Motorola type II control channels.. I
inputted them into the scanner but they're pretty useless without the
rest of the frequencies that make-up that system.
Is there any hard-and-fast way of finding those frequencies? Also,
I've scoured the net to no avail.
I am in the Memphis, TN area and the control channel frequencies in
question a
856.8625
855.5625
I noticed that all the trunked systems I can scan seem to follow a
convention, where the control channel is the "last" in the chain,
along a sequential list of frequencies... for example, 85x.2125 .. X
can be 5 - 9, and then 860.2125 might be the control channel for that.
So, I tried blindly entering frequencies like that and I managed to
partially clear-up this mystery with another system.. but this method
hasn't worked with these two.
Does anyone have any suggestions or information? My aging scanner is
getting left out in the cold more and more as the older trunked
systems it can monitor are replaced with ones it can't, so I would
really love to monitor every possible system out there in the short
time I have left! 
Thanks in advance for any help.
