[Elecraft] K3/0 and RTTY

[Larry - K1UO]

Got the CONFIG: SYNC DT off finally...Thanks so much.      RX Signal levels 
on RTTY are S9+..still gibberish decode over the Remote system?

Both RTTY and CW decode should work remotely. Use a narrow filter passband 
tune the signal in carefully using the CWT meter scale (pgs. 33 and 34 of 
the owner's manual). Decode accuracy is affected by noise, fading, and 
interference, but should work as long as the signal is correctly tuned in 
and has a high enough S/N ratio. CW decode is more difficult in the presence 
of noise and sloppy timing.

If you see the "-S" icon on the LCD, you are in "sync-data" mode, which is 
typically used for AMTOR or PACTOR (pg. 32). These modes require faster 
turn-around times, which the K3 facilitates by not switching crystal filters 
between transmit and receive.

The only way to get the K3 into sync-data mode is to assign the CONFIG:SYNC 
DT menu entry to a programmable function switch. You may have done this 
accidentally. To get it back out of this mode, temporarily assign this menu 
entry to a programmable switch, exit the menu, then press that switch. This 
should turn off the -S.
