In the list below Michael, a Channel 6 Station is shown to be in Middleton.
Assuming you are in Halifax, and you are receiving Pings 75 miles from the
transmitter in Middleton, you are an ideal distance for receiving pings. In
the Table below showing Antenna elevation, notice that the direction of ping
incidence onto your antenna at 75 miles is approximately 60 degrees; in
addition, orient the antenna vertically for vertical polarization; the
elements pointing up and down rather than horizontal. By tilting or pointing
your antenna toward the source of the forward scatter reflections, you will
boost the gain of the Pings by almost 50%.

Subject: (meteorobs) Question - radio meteor
Hi:
Well, up here in Halifax,NS,Canada 44N 63W there is not many analogue
stations now, I still
use 83.24 MHz and hear a few meteors, rest of frequencies 67.24,55.24 I hear
nothing at all. I have no
idea what others are hearing at 61 MHz! tried but nothing.
Anyway, just a curosity question. I listen in CW mode but a few times
messing around I listened
on AM mode and heard odd meteor pings just like a tuning fork. Why can I
hear theses on AM ? Is this
the same AM as our radio use? wish we could use AM! I am just at a
loss now to find some
frequency to try.
I'm in an apartment on the top floor and this part of the city is * supposed
* to be the highest.. I'm about 57 meters
above sea level.
Clear skies
