Yes, there has been a considerable amount of tropospheric ducting into the
northeastern Canadian provinces over the past two or three weeks; but never
fear, those excellent conditions are about to end and the meteors will
again reign!

You may mean 300 kHz. I'd be somewhat surprised if you could detect any
difference if the filter was mistuned by as much as 3 dB which is probably
around 300 kHz for a very-high-Q single cavity filter at 83 MHz.

Right.

So you were monitoring TV channel 6; I don't know which station you could
have been hearing but it was probably somewhere in New England as we've had
outstanding tropo conditions up your way beginning about a month ago up
through last weekend. But it's dissipated now and probably won't return
again; at least, not this good.
