420.175 comes back as the same license as the Fort Erie site for FWC (site 3) so probably an addition to that location. 420.350 is also a FWC license at Caledonia and Queenston, and part of the F.W.C. TIII system. That's not new.
FWIW, I've still not seen an active control channel related to a site 6 on that system from up here, which is supposed to be Queenston. Somebody local needs to go up there and see if it's active given that it shares frequencies with Caledonia. That site (#2) I do receive no problem and am watching it right now. I don't stand a chance with Fort Erie as there are much stronger active control channels from other systems right next to it's frequencies that are swamping out any chance of my seeing it.
