Hi all!
There are something like 16 units of OsmoSDR that we are able to sell in something like one week. Sale will happen via the https://shop.sysmocom.de/ webshop.
However, as there are only 16 units right now, and as the firmware and host software is in an incomplete state, we would like to make sure that those 16 units get sold to people who actually have an interest (and time!) to fix and improve the current shortcomings.
So if you want to be among the first 16, I suggest you reply to this message and give us a short description of who you are (if you are not a Osmocom regular) as well as some committment that you are actually going to work on improving the code. If you already know an area that you'd like to work on, please state that, too.
The price will be 180 EUR incl. VAT (that's 151.26 EUR without), i.e. the same price as for the units that will later be sold openly.
I have put together a wiki page with the current status at http://sdr.osmocom.org/trac/wiki/OsmoSDR/Status to make you aware where we are and what is missing.
Thanks in advance for your willingness to be early users and help us to improve the codebase.
Regards, Harald

Great news!
Do I recall correctly that it supports 10MHz to 1.4GHz frequency with up to 4MHz bandwidth with 14 bits resolution and does not provide any Rx filtering?
Regarding decimation support in FPGA - as a quick way I recommend to look at borrowing code from Ettus' UHD FPGA. It's GPLv3 and is well modular. So you could be able to take only decimation from it. Other blocks like I/Q balance. DC offset removal, VCO are available as well. This could be an easy way to start. Let me know if someone wants to go this way and need some intro into the UHD code structure.

64 MHz to 1.7 GHz (spec) but you can still go up to 1.9 GHz without problems. The ADC can do 4MS/s, but the SSC of the sam3u can only do something that roughly correpsonds 1.25 Ms/s.

I'd like to order one to work on the control interface in firmware as well as on the host. I've said that for a while, and while this can be done even without hardware being able to test helps (at least my) motivation a lot.
In any case I'm of course happy to assist others with anything and everything related to libusb, including problems upstream, where being able to test locally can also help.
I'll make a deal: Consider reserving a device for me only if I deliver some patches for USB stuff in firmware and host before noon Monday next week! :)
I also have another idea: Let's schedule a hackaton (code sprint, pick your favorite name) next week when hardware has arrived, where those with interest meet up in Berlin and hack together on the TODO list, which will allow us to more easily share the hardware even if there are only a few devices available. Peer pressure also helps get things done.

Just as a follow-up:
There have so far not been that many people interested in getting one of the first units, so maybe my last post was too scary. I think there should still be some 8 boards left after subtracting orders for the "usual suspects". So if you are interested and want to play with it as an early adopter, feel free to send me a mail and I'll let you know how to proceed with the order.
Regards, Harald
