1) I have 2 "sets" of freq's....140ish Mhz and 800ish Mhz. Does this seem
right? (these are for the London ONT cops)

The official site says they're using a "3 site, 20 channel, 800
megahertz trunking system", so I'd recommend the 800 MHz freqs.

3) The manual states that with EDACS systems, the channels have to be in LCN
(logical channel number) order. Is this simply in order by frequency # or
is there another way to determine the LCN?

The LCNs aren't necessarily arranged in order of frequency. If you
don't know the LCN assignments it's possible to determine them by
trial and error.


2) I seem to have 2 800 Mhz control channels (CTL-01 and CTL-02 on the
display)

If a control channel is active, the CTL-01 or CTL-02 should be
intermittently replaced by talkgroup numbers when users are talking on
the system. Do you see that?

The other freqs -- do they sound like they're trunked and part of the
same system? Park the scanner on each one for a while and listen. Are
you hearing voice? The web site says the system was designed to allow
digital encrypted voice. The PRO-95 can't handle digital voice, even
when sent "in the clear".
