[Elecraft] K3 Line-In for PSK31 not working

[Greg - AB7R]

Set your soundcard volume to about 50%

Connect soundcard output to the K3 LINE IN.

Connect the souncard input to the K3 LINE OUT.

Set Menu item MIC SEL to LINE IN.

Set mode to DATA.  HOLD DATA MD to choose Data-A.

Set power to ~20W (just something to start with).

Use the MIC control to set the drive level so that your output is equal or just below what 
you dialed in (20W in this case).  CMP is locked at zero.  

When setup this way I get excellent PSK31 results with TX IMD at ~ -34 dB.  


FOR PTT

You can use a seperate line for PTT to the ACCY connector or the RCA PTT connection on the 
back of the K3.  You can also use the RS-232 serial connection if your software allows you 
to set it up that way.  

Set PTT-Key to either RTS - OFF or DTR - OFF in the CONFIG menu.  Then in your software set 
PTT to either DTR or RTS as appropriate to the same COM port the radio is connected to.  
Note not all software allows you to do this.  Depending on the software you can also try 
PTT via CAT command (this works in MixW).


Hope this helps.
