Re: High pass filter

While the qrm you see may be coming in from what you consider to be the antenna it may actually be sourced by ground currents or common mode sources.
If it's the latter, increasing symmetry

Re: WSPR reports on 40M, also config includes only 20M
Hi Gur,
I have just checked your Kiwi and see that the spectrum is now much cleaner and WD is finding many spots on the 20M band you have configured it for.
Why don't you disable the last Kiwi autorun

Re: WSPR reports on 40M, also config includes only 20M
Your Kiwi is configured for multiple autorun sessions, all on 20M. You need to disable all of them and configure the Kiwi to accept at the number of WD bands.

I Need to wait few minutes to see again the impact.

Re: WSPR reports on 40M, also config includes only 20M
Hi Rob,
You are right, I had to test a different remote networking unit which introduced all this noise.
I now removed it.
If you take a look now it should be quieter.
I have also improved the GPS

Re: WSPR reports on 40M, also config includes only 20M
Also, did you stop WD before making the change to its conf file? You might stop WD (WD -z) and then start if again (WD -a) to ensure it is using the current version of the config file.

Hi Gur,
Boy, you have so much RF noise that it is a wonder that you hear anything.
Also, you are tracking only 3 GPS satellites, so are you sure of the accuracy of the Kiwi's tuning? If the WSPR

Re: KiwiSDR dynamic IP address
Thanks.
But maybe I missed something.
I still need a way to run the RSS command.....
ssh -R 8073:localhost:8073 kiwisdr@...
I need to automate it ?

Good debugging!
The tunnel is a Kiwi daemon which will restart if the ssh session from the Kiwi to your server fails.
In order for that daemon to start during a Kiwi power cycle or reboot, there needs

Re: KiwiSDR dynamic IP address
First, on the Kiwi run:
To see the status of of your tunnel: ./wd-tunnel.sh -s
To watch the log file output of the running tunnel run: ./wd-tunnel.sh -l
