[Elecraft] Low Tx Data Sound Output volume

[Don Wilhelm]

Irwin,

Did you get the information that Elecraft radios are different than 
other amateur transceivers?, and that you have to set up the audio and 
power differently.  It sounds like you may not be setting the audio and 
power correctly for the K3/K3S.

The common internet "advice" is to set the power to maximum, and use the 
audio level to control the power output.  That does not work well with 
Elecraft transceivers - ignore that advice.

With the K3 (K3S, KX3 and KX2), set the audio to produce 4 bars on the 
ALC meter with the 5th bar flashing and adjust the power with the Power 
knob on the radio.

AFSK A should be no different than LSB except that compression and TX/RX 
EQ is automatically turned off.

For PSK31 or other data modes, the use of DATA A submode (which is USB) 
is recommended although PSK31 does not care about the sideband.  Other 
soundcard digital modes do care.

Please refer to the K3 Data modes article on my website www.w3fpr.com. 
Scroll the left column down to the bottom and you will find the link to 
the page.

73,
