[Elecraft] SignaLink and K3

[Don Wilhelm]

Bill,

If you are using the MIC input on the K3, then that statement in the 
SignaLink document is correct, but if you likely have the SignaLink 
connected to the K3 LINE IN jack, and the level is too low.  Line level 
is about 5 to 10 times the audio voltage of mic level.  Sooo --

Set that jumper for high level audio, then:
Put the K3 in TX TEST and set your software application to transmit.
Adjust the audio level controls and possibly the K3 LINE IN level so you 
have 4 bars displayed on the K3 ALC meter with the 5th bar blinking.  
Leave the audio controls set that way.
Adjust the desired power output level with the K3 power control - ignore 
the advice usually given on the internet and interface help files to set 
power at max and adjust the audio to achieve the desired power - that 
will not work well with the K3 (or the K2 and KX3 either).

73,
Don W3FPR
