[Boatanchors] "Chirp is a Beautiful Thing"

Hi,
Some of the old timers like to howl and carry on about how they used to
walk 10 miles to school through chest deep snow uphill both ways. And
how they could so easily pick out one transmitter from the many that
could be heard simultaneously on a novice band. Those transmitters all
had their own, individual voices and combining that with all those
individual fists - of course it was easy. At least less difficult. Some
amount of chirp is one of the ingredients. The accursed 'yaecomwood'
radios are pretty much "sterile" and all sound alike. CW is sent by
keyers, memory keyers, and computers. Pretty much sterile, too.
I have looked at some signals with varying amounts of chirp on waterfall
displays and I see a small "j" hook on the leading edge. It doesn't take
much. There is no need to sweep a dit or dah across two or three QSOs in
progress but a small dose of chirp goes a long way toward individual
identification. Put the same amount of 'hook' on the other side and two
otherwise identical stations are *different*. I have heard some signals
in the past that I know must be from a small amount of modulation -
perhaps FM - on that CW tone. It wasn't enough to identify the source of
the "problem" but it was enough to identify one ham and his station -
instantly. Operating as NCS in NTS traffic nets I could recognize and
acknowledge certain stations from just one character in Morse. It isn't
all bad.
