[Elecraft] Side Effects of QRQ On The K3

Sun Apr 13 13:24:54 EDT 2014

Dave,

I have no problems running full breakin at my comfortable speed of 20 to 22 wpm.  During a contest I will push the speed up a bit but still have no problems.

I much prefer full breakin though because during some pileups and even during some of the CW nets that I participate -- not hearing the other signals really affects things for me I think.

73, phil, K7PEH

P.S.  

I know there are guys who can copy 60 wpm and greater but it is a true mystery to me.  I think my absolute limit for copying call signs might be 40 wpm but then I have to hear the call sign several times.  Usually picking up the suffix and then going back to get the prefix.  Works well in a contest since calls are repeated a lot.  I think I can do a simple contest exchange at 40 but only because I know what the other guy is sending before he sends it (or, almost).

A friend of mine was some kind of CW record holder in the army 40 years ago.  He was down in Panama or something like that running encrypted messages at extremely fast speeds at 3-digit wpm.  He is not a ham though.
