[TrunkCom] EDACS systems with the anti-scanner tone or possible interference?

[Jeff Kenyon]

Hi everyone, last weekend during a band opening on Friday night I was
getting a lot of distant trunked systems, both Motorola and EDACS.  I
noticed that on the Livonia, Michigan system on 866.7125 wherethe control
channel was on Firiay I was hearing that annoying buz sound coming in with
the EDACS CC.  Upon checking radioreference.com I noticed that London
Ontario's EDACS system is using 866.7125 as one of its freqs, and I am
thinking that this system was what was doing this, but I am just wondering
if anyone has noticed that the two systems could potentially interfere
with one another?  Also, did anyone else in the midwest on Friday night or
Saturday morning pick anything up from a distance?  I heard not only the
two systems, but Michigan State University's System, and the Clinton
County EDACS system, and both of those
 are a good 90+ miles from me.
