v1.689 (and later) has countermeasures against the "botnet".

v1.690 (and later) is necessary for your Kiwi to resume using the proxy service.

These updates will happen automatically overnight (local time) unless you've disabled automatic updates. You can manually update by going to the admin page "update" tab and clicking "build now" and waiting 30 minutes or so for the build to complete. Your Kiwi will restart when the build is complete.

Don't start multiple threads about the botnet topic. They will be deleted.

The proxy service has been disabled because the money (for which I am not compensated) is now flying out of my back pocket:

I will try and develop a fix in the code to better identify and remove these connections.

Update: The proxy service has been re-enabled if you're running v1.690 or later.

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!

From the CHANGE_LOG file:

@ok1iak Well, here we are. Over two years later. I had not forgotten about this. For various reasons I decided now was the time to give it a try.

This is an extremely early result. There are all kinds of problems. Currently, all I can get semi-reliably without too many glitches is a wideband output of 240 kHz. I'm pretty sure more can be done with some optimization. There is no CIC filtering in the FPGA yet, so there is aliasing.

To get SDR++ working as quickly as possible on my Mac the easiest thing to do was write a very quick and dirty SpyServer implementation (partial) from the public spec. That's why below it says "SpyServer", "Int16" and "RTL-SDR". But it really is connected to a Kiwi-2 on the special SpyServer port 5555. I have not tried SDR# yet. This Kiwi is on the other side of the world from me. So it is streaming at 240 kHz over the Internet successfully.

You can't make any Kiwi user connections when the Kiwi is configured for wideband mode. But you can make an admin connection. Lots and lots of work to do before this is ready for any sort of release.

The cases have arrived and David, ZL2BA, has been busy assembling the units.

The store should open in less than a week. Everyone that emailed sales@kiwisdr.nz will receive an email reply when the store opens. It will also be announced here, on Twitter and the various web pages.

Many units will be shipped to ML&S (UK) and WiMo (DE) as well.

Thanks everyone for your ongoing support and patience.
