It's been a while since monitoring this system (Gatineau P26) but tonight I am getting a "new???" site 106 with a Control Channel on 866.4875 while running Pro96Comm.
Interesting, I believe that used to be their MDT channel long ago when they were on VHF.
Unfortunately, can't help much more. Have tried UniTrunker on two different PCs (desktop and
laptop), two different OS's (Win98 and XP Pro), and different versions (Legacy and recent one),
with adjustable audio attenuator cable, with no luck.
