That README page is slightly confusing because the picture of the air-core coil and first schematic appear adjacent to each other. The two schematics refer to the second picture which shows an "AM loopstick" style ferrite coil which could easily be 700 uH I would imagine.

Brings back memories of when I ran a LOWFER beacon on 175 kHz back in the early '80s. 1W input using an IRF510. And an output coil wound on a 200x500 mm coil form using Litz wire. Heard all over the western US. Was it really that long ago? Am I really that old? What happened!

Nice. Well, it's all about the field strength. Very likely you can build something useful that will not be detectable outside of your immediate location.

And, you can use your Kiwi to test it -- the timecode extension!

I just replied to your email before I saw this post. So I'll include my email reply here:

So it turns out the default dx.json is stored on every Kiwi in case it turns up missing during a software install. If you bring up the admin console try these commands to see the differences:

In my case it showed dx.json had a few new lines not present in the default file.

You can replace the "wc" (word count) with a "cp" to copy the default file to the current dx.json. You can use "diff" to see the actual text differences.

You should immediately restart (admin control tab) so the server doesn't overwrite the dx.json file you just restored.

All the currently supported switches, including Ethernet-based switches, are listed here: https://github.com/jks-prv/KiwiSDR/tree/master/pkgs/ant_switch

There is not a proper pointer to that in the base documentation, so I will fix that. Thanks.

KiwiSDR 2 radios are available again in our online store: https://kiwisdr.nz

Thanks for your support.
