Wideband IQ streaming mode for local processing? [better late than never!]
@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.

Private use of a KiwiSDR receiver in France
Well, none of this is really new. It's just operating in the modern context of SDRs and the Internet.
Hams have been "bootlegging" callsigns for nearly 100 years. Pirates have always existed.
Most countries technically have regulations allowing radio monitoring for personal use, but prohibiting "retransmission". But the precise interpretation of those terms for HF are vague at best given the border-crossing nature of HF. And HF is mostly uninteresting to everyone except us anyway.
Much more applicable to VHF/UHF short-range communication services that might be impacted by retransmission. Although encryption in recent times has made that point mostly moot.
To your last point: I don't think it makes any sense to be including, on a public list, any Kiwi that requires a password likely to be unknown by 99% of the users connecting. That makes its inclusion completely worthless. Perhaps a separate area listing "private" access Kiwis? But that doesn't seem worth the effort.

KiwiSDR 2 production status
We've received another run of boards. Assembly, programming and test are in progress.
One issue is that a huge quantity of the enclosures we had shipped by cargo container instead of air freight. But due to bad weather the container was delayed. So the finished units won't ship until later this month (June).

v1.683
From the CHANGE_LOG file:
v1.683 May 30, 2024
Antenna switch: Fixed problems with Arduino Netshield backend script. (thanks N8OOU)
CAT interface: Removed newline characters (\r\n) from end of each transmitted CAT string
because it was reported to cause problems with some CAT software. (thanks DF6DBF)
DX community database: UNID FSK signal at 61.84 is Inskip GBR. (thanks HB9TMC)
Added entries to satellite table for Galileo gsat0227 and gsat0225 launched 2024-04-28 and
currently under commissioning. (thanks F4FPR)
We have now formally purchased a license to use the Kiwi logo from Hayes Roberts at
bluebison.net. Previously we had an informal agreement with Hayes where he allowed us to use
the logo provided we always included the domain text "bluebison.net" wherever the logo was used.
By purchasing a licence we can now remove the text and make uses of the logo look a bit cleaner.
Big thanks to Hayes for giving the KiwiSDR its logo identity recognized by SDR enthusiasts
around the world.
