[Elecraft] K3S's built-in RTTY

[Bill Frantz]

In the CQ WPX RTTY contest I ran RUMlog's contest logger which 
uses the K3 programming interface to encode and decode RTTY*. I 
also ran cocoaModem using the KIO3B's "sound card"#. I used its 
crossed loop indicator for tuning and occasionally looked at its 
decode. The combination worked quite well.

In summary, the internal decode works quite well. I haven't 
tried the internal encode, not having room on my desk for 
another keyboard and being terrible with a paddle.

* When using the internal K3 decoder through the programming 
interface, it is necessary to turn off the decode display on the 
P3's SVGA display. Some part of the Elecraft system runs out of 
CPU horsepower and the result is severe character loss on both 
the PC and on the SVGA.

# My K3 has all the upgrade boards Elecraft has released. It is 
almost a K3S.
