Sorry to interrupt the discussion on emergency nets... :.)
You may recall, several weeks ago I posed a question about getting a
keyer that sends faster than 60 WPM via the paddles. I'm currently
using a CMOS Superkeyer III. With some help from one of the keyer's
designers (KC0Q) I now have a solution - I overclocked it. The keyer
is designed with a 2 MHz ceramic resonator for timing. I replaced it
with a 3 MHz ceramic resonator. I have to multiply everything that's
calibrated (speed, sidetone, etc.) by 1.5 for the true result, but it
did the trick.
I don't know if anyone else would ever have the need for such a
thing, but it's now in the archives for posterity.
