General Notes on Transmitting:
1) DO NOT overdrive the transmitter if you are using the microphone input. If you notice that the
ALC circuit of your transmitter becomes active, you are overdriving your transmitter
2) If you use a speech processor for voice transmissions, be sure you turn it off or disconnect it
during RTTY transmission.
3) Reduce the power output of your transmitter while transmitting RTTY. RTTY is 100 % duty cy-
cle and failure to reduce power could cause damage to your transmitter.
4) Make sure that the passband of your transmitter is of sufficient width to pass both the Mark
and Space tones you are using.
THERE ARE THREE WAYS TO SET THE ST-6000 FOR TRANSMITTING:
1) KOS activated
2) Print switch in LOCAL position
3) REMOTE STANDBY line grounded
