Here is my setup with the Elecraft K3 with the KXV3A
K3 Menu settings are as follows
- Mic set Line in
- Line out Nor 10
- PTT-KEY rts-dtr
- RS232 38400
K3 radio settings
- Mode data A
- Filter 2.7
- NB off
- Meter ALC
- AGC slow
- KXV3A line out to computer sound card Mic or Pink connector.
- KXV3A line in to computer sound card Green connector. (this is a mono cable in my case)
- RS232 from K3 to computer.
WSPR menu settings for K3
The best way to do this is with a snap shot of the setup window from the WSPR program.

So lets give WSPR a whirl
These are the steps I use to get WSPR up and going with my setup here.
- I setup the K3 according to "radio settings" above.
- If you noticed in the WSPR menu settings above my com port was set to 8. This is a virtual port in the LP-bridge program. So I now start up LP-bridge if not the K3 will not go into transmit.(found that out the hard way)
- I now start up WSPR and under the band menu I select the band I am going to use. The K3 is also switched to this band through CAT control.
- My antenna switch is set to the dummy load position.
- In the WSPR program with the Idle checked I select the Tune button and WSPR goes into tune mode.
- I now adjust the Mic gain on the K3 until the output is 5 watts. (I will be dropping the output later)
- I use my LP-100A to make sure the output is at 5 watts...or there about.
- I then switch to the proper antenna and remove the check mark from the WSPR idle and we are on our way.
Below are some results on 40 meters in the afternoon during a very noisy RTTY contest that also was on the band.
Here is a sample of how busy 40 meters was with the RTTY contest while trying WSPR.
