You may not have gotten access to a bird from the windowsill with the house
shielding it from all but the one direction...missing the target birds.

The signal level at even the edge of the atmosphere where Spots birds fly
is simply just above the background noise level at the receiver. During
the day, you'll notice if there are any obstructions like you have it now,
the attenuation of the obstruction causes the noise from the sun, the
biggest broadband transmitter in these parts, to be stronger than what's
left of the Spot's little peanut whistle transmitter....and the bird only
picks it up at night when the Earth shades the sun's racket from the birds.

Just think back to how big those old satellite dishes were from
geostationary orbit 32,800 miles over the equator. You had to have THAT
big a capture area, just to have enough signal pointed at the little
feedhorn to overcome the heat noise of the receiver inside the horn. Oh,
how times have changed....(c;

Imagine how tiny and buried in the noise the signal from Voyager 1 and 2 is
out in the Oort Cloud. The signal comes from a Traveling Wave Tube that
has been constantly operating since 1967! And they told you TUBES were
unreliable. By the way, last I looked, the "data recorder", which records
science data from Voyager on a reel-to-reel data cassette, was still using
the SAME cassette since 1967, too! Simply unbelievable at 1967 technology.
