  • This is why we can't have nice things

    Like I have time to setup and manage such a thing, lol

  • KiwiSDR 2 production status

    Just waiting on the container with the cases now. Units otherwise assembled, programmed and ready to go. Should be in a week or two (early July).

    Another build for August/September already underway.

  • 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).
