Title: CW weight and intelligibility of calls
Post by: WX2S on December 31, 2013, 07:45:36 AM
Hi, all,

A lot of people select calls according to CW weight, lower being better. But I'm thinking that there are other important factors to intelligibility in QRM, QRN, and QSB. These factors are, to me, murky, having to do with human hearing as well as physics.

A nice rhythm in the call may help, like E77C.

Having a lot of dits on the end of a call may make it less intelligible. I've often had stations drop or add dits to my call.

What do you think?

73 & HNY,

Callsigns with sequential characters consisting only of dits combined with QRM and weak signal etc.  can be challenging.

Nuts. W2ESE was probably available.

Second thought, scratch that. It's an obscene insult in Spanish.
