[Elecraft] KX3 + fldigi (PSK31)

[Don Wilhelm]

Kyle,

Not answering about the receive waterfall because it appears you have 
some other things to clean up first.

The ALC bars are important.  Set the TX audio level correctly so you 
have 4 bars solid and the 5th bar flickering on the ALC meter.
Too much audio drive will trigger an audio 'overload' in the KX3, so set 
the mic gain to a low level, and set the soundcard line out slider to 
about half to start with.  Make certain the SignaLink is plugged for MIC 
level, and not for LINE level.
Once you have done that you should be able to transmit.

The KX3 ALC is *not* turned off in DATA A mode - what is turned off is 
compression and the TX EQ settings.

As far as not going back to receive, if you are using the PTT from the 
SignaLink, make sure the KX3 VOX is off.
Actually, you should be able to operate without the SignaLink PTT output 
and use the KX3 VOX instead, just set the KX3 VOX gain at a level that 
triggers the VOX reliably.  If you are using the SignaLink PTT, it may 
be triggering on noise if you have the 'soundcard' level set too high.  
The SignaLink PTT is driven by a simplistic VOX circuit in the SignaLink 
which senses audio, and with a high audio level, it cannot differentiate 
between a real signal and noise.

Try manual transmit rather than attempting macros until you get it 
going.  You are playing with several variables at once, reduce those to 
only one or two and add one at a time after you get it working.

73,
