Not necessarily!

At 30 wpm, the displayed code requires a sweep time of about 1.2 sec


Agreed - but at a sweep of 1.2 seconds, the phosphor would need to
have a pretty long persistance to make a nice even display like the
one pictured.......bright, too!

My Tek 465 can't do that - where can I buy one of those?


73 de Jim, N2EY

Can a person even do 30 wpm with one of those? I didn't read the article
yet, but that seems pretty fast.


The article claims 25 wpm or more from this device.

Wow!


Maintenance isn't
mentioned, though - one shudders to think what that thing would be
like after a couple of weeks of use! Ewwww.

Good point! Ever see the mouthpiece of a saxophone after a couple weeks
use? It isn't pretty...
