      Dave, I ordered a UHFSDR some time ago too.  I want to make a driver to control Si570 direct on I2C for raspi.  Alas, I have not received the kit and it's probably time to go track it down.

      The raspi should have enough power to decode SSB from 48k i/q frames and data modes might be possible at higher speeds.  It's a pretty easy matter and standard practice to adjust the quantity of filter taps to match your hardware.  Unless forums posts are counting MACs, you can't believe a word of it (or me either since I have no raspi to count MACs on).

      I signed up for a raspi many months ago but woke up this morning to find out I won't be getting one.  I had also wanted to make a board for putting a nice codec on the raspi but they aren't wiring I2S so there's no point in that.  Grrr.  This is not a failure on my part.

      With all the backstabbing, trolling, and resistance I get to working on ham21, I'm not sure when I'll be motivated to pack up a gem release with SSB.  It should happen before the raspi ships.  Regardless, SSB is decoding in Ruby and I'll be presenting the DSP technology I invented to a room packed full of Ruby developers next week.  I'll be using one of my SoftRocks in the presentation.

      Has any one considered the above processor as the core of a stand alone T/RX. On the face of it, it is shouting out to be used for a more chuckable rig than the current PC / Lap top configuration.

        However they've said that production in the UK in future may be an option.

        That's neat .... but im a little surprised that they didn't know beforehand that china manufactures didn't care about GPL license ... they have ignored copyright for years and are still actively hacking systems for any high-tech information.

        Sorry :(  I don't think the project is quite as far along as the Pi. And I am rather fond of Pi. But that's another story. For now, I have to go to work, but when I get home if I remember I will find it....

        Not quite as early as I promised, but hey, at least now I can go back to lurking without being called a tease, right?
