Well Jim, the reason for sending CW at speeds over 80 wpm is because there
ARE hams who can copy it. And Jim, they do it by ear, simply because a code
reader (or none that I know of) can copy that fast in the presence of normal
band QRN/QRM. ONLY the human ear can do that. Besides, if you want to get an
extra enjoyment out of our hobby, and with CW, high speed and fast full QSK
will certainly provide you with that.
Everyone who hears us running QRQ on or around 7.033 swears that we have to
be using a code reader and they try to get on frequency and jam our
'readers', but Jim the best CW filter ever made sits on each side of your
head, and you can not jam it! So as long as it remains FUN, we will enjoy
it.
Try it, you might like it!
