Noticed the FM stations using auxiliary powers in the wee hours Tuesday morning. This time I was in Toronto. Signals seemed ever so slightly weak downtown, and no IBOC digital sideband on the Tower stations noted. So I drove to the Scarborough Bluffs for a quick check.

I was surprised how well the signals held out there. Nothing was really getting too badly beaten up. Though I was easily able to work adjacent channels (eg., 107.3 had a Buffalo translator for the 1400 AM RnB station there). Also, six of the eight stations still had RDS systems working - CHFI and CJRT did not.

So I'm curious to know what power the stations' auxiliaries run at? Do they all broadcast from off-site - I'm presuming First Canadian Place? Have the auxiliaries upped their power in recent days? At my DX site north of Lindsay last week, only 99.9, 104.5 and 100.7 made it with relative ease. I had to work hard to get the other five to come in at all. When I last noted the CN Tower off, I vaguely recall CHUM being the only one to carry a truly decent auxiliary signal and some didn't have them at all.
