I wish I could pay more for Massdrop to use a better shipment method. They will ship in 5 weeks and then I expect to wait for 2 weeks for the package to cross the USA ;=(
It would be nice to have the aluminum case as an add-on. Just ordered it from Seeed Studio with $5 for shipping. Now the big question is will the KiwiSDR be here before the case or will I get the case first :)
Any idea on an ETA on these?

Nothing yet ?
I am disappointed by the choice of shipper. It will take 2 weeks for my order to travel from NJ to CA. I wish I could have paid extra for USPS 2nd day or other 'normal' shipment options.

Massdrop send to Brazil? When will we get a good discount?
Thankyou!

Dumb question time... Does this come with the aluminium enclosure?
Rocky_Rhodes
No, you'd have to purchase that separately from Seeed. The aluminum enclosure was developed after the original Kiwi kit which still ships using the original plastic/metal enclosure.
KiwiSDR
I have ten KiwiSDRs with the Seeed metal case. It is very nice but I think only available directly from Seeed. It would be nice if teh cases could be ordered as options right here on Massdrop but directly from Seeed to the USA works well.

Our first receivers are already being deployed around theCaribbean and South America.

The only thing to watch is to make sure you only put the double-sided foam tape on one side of the fan, not both.
Sorry for being a normie, but what are these devices generally used for? Just curious because it seems interesting.

Web-enabled shortwave receiver. Have a listen to a few hundred worldwide that Kiwi owners have made available online: sdr.hu
why by this instead of a hackrf one? i am being serious. pros cons and price to performance?

Fair question. In short, the Kiwi is designed to be a plug-and-play, web-accessible "shortwave receiver" SDR that goes from VLF up to 30/32 MHz. You don't have to install any software on your host computer. Just use a browser to connect. You can also make it accessible from the Internet for others to listen (up to 4 simultaneous connections).

HackRF is a more traditional "IQ generator" SDR that's really for the VHF/UHF crowd in my opinion. Very popular with security researchers. It does receive down to 100 kHz. You connect it to a host computer via USB and have to install/use third-party software. But that's not a huge deal. I put together a comparison chart here: http://www.kiwisdr.com/ks/compare.1.1.pdf Of course you can listen to hundreds of KiwiSDRs worldwide on sdr.hu and decide if it meets your needs. Note that the receive performance of individual Kiwis on sdr.hu vary greatly due to the local antenna and noise situations.

I should also mention this comprehensive KiwiSDR review: https://www.rtl-sdr.com/a-review-of-the-kiwisdr-10-khz-30-mhz-wideband-network-sdr/
And of course lots of information on our website: kiwisdr.com
i need to get ten KiwiSDR receivers ASAP but was not able to get my order ptocessed on the last drop. Hopefuuly they will have another drop VERY soon. These are planned for Caribbean and Latin America deployment.

Drop is active. Hope your able to join this time around.
I'm getting ready to set up a KIWI SDR for testing on sdr.hu in Philadelphia. What's a good low-noise power supply for use in the US? The earlier ones I saw were Europe 220V ones.

Hi Robert. Sorry, only saw your message just now. There is a section on the Kiwi website about linear power supplies (http://kiwisdr.com/quickstart/index.html#id-power) I would recommend one of the "audiophile" supplies from China via Ebay. Be sure to specify 115 VAC / 5 VDC to the seller so they can configure the supply before shipping.
KiwiSDR designer here. Thanks Massdrop for offering people a great price. Always nice to see a little capitalism in action (although everyone seems to be making money except me, lol). Happy to answer any questions. Also, please check the "wall of text" at kiwisdr.com and forum at http://valentfx.com/forums/#/categories/kiwisdr-discussion

I'm interested in using this unit for ADS-B. Do you know if it'll support tagging incoming frames with the GPS timestamp for MLAT?
shaneshort
I don't know much about ADS-B, but doesn't it operate at 1090 MHz or something? The Kiwi is a "shortwave" SDR with a top frequency of 30 MHz (32 with degraded performance). You could use a downconverter I suppose. But aren't there already complete solutions using an inexpensive RTL-SDR plus a Beagle or R-Pi? I'm not sure what advantage a Kiwi would have for ADS-B.

[edit] I should add that there have been requests for high-resolution tagging of the mono audio stream data and (future) IQ output stream with GPS timestamps. Presumably for use by downstream applications. Applications typically use a program that listens to the audio output of the browser via a "virtual audio cable" adapter of some sort. It is also possible to write "extensions" for KiwiSDR where you can load a small program into the server and/or browser to do custom processing (existing ones are under the "extensions" menu in the user interface).
