Who the heck is copying that and what are they copying??? The highest speed record for a long time, of copying unexpected text, was only around 70-80 WPM. That record held the whole time I was growing up, and it was from the 30's I think.
It is certainly impossible to copy 300 WPM without decoding. I have some nagging questions about these speed claims. ----- Original Message ----- From: "David Cutter" <[email protected]> To: "Paul Christensen" <[email protected]>; "Elecraft Reflector" <[email protected]> Sent: Saturday, May 15, 2010 7:40 AM Subject: Re: [Elecraft] K3: QRQ high-speed QSK > This is a *little* OT, but I've just read in a 1914 WT > book that they were > regularly running at 300wpm on spark transmitters.
