[Elecraft] MMTTY not keying transmitter

[efortner]

I am trying to run RTTY FSK with my elecraft K3s SN 10326  K4KAY Earl. I am
using MMTTY software and Timewave Navagator. It receives well and appears to
be working properly. Every thing looks right on the MMTTY screen and the
PTT, CAT, FSK leds light on the Navigator. The Tx led below the power button
on the K3s lights but I get no RF out of the K3s and the KPA 500 will not
key when switched to OPER. I have the K3s set to data and MMTTY set to Radio
Command and TX Port is com-TXD(FSK) USB.

 

I have checked on the comports and they are up and correct.  Anyone have any
suggestions.
