Hmmm,
Inevitable I guess;  A few hours left to accquire a neat radio.  Looks like by the time it makes it back to the states (if it does) it'll approach list or more what with duty again, shipping, final bid, etc.
It seems to have a British accent.  Curious what the serial number is?
Only one guy I've heard of thought of selling his and posted such on this board Grin

OH ! , I just found this on the Yahoo users group;

****************************************************************************
"Hi, I don't want to use this group as a marketplace but members of the
group may be interested in my QS1R that's for sale on eBay right now.
I just don't have time to play with radios right now so its got to
go! The listing ends tomorrow evening (UK). Email me privately if you
want to offer me a huge pile of cash for it!

I'll still be keeping up to date with the groups activities and I'll
probably buy another one in 6 months time! Many thanks to Cathy and
Phil on such a superb open source project.

Interesting review of the Perseus in the December QST on pg 40.

Great Frank.
I haven't gotten my Dec. issue yet so looked up the review online.

Neat board, and has the LTC6400-20 (20db) preamp ahead of the LTC2208.  So I looked up the LTC6400-20 and the hook up is very simple. From the QST pix it looks like Mercury has a full set of filters.  I saw on the LTC6400 page that a compliment of LPF's were referenced.  They must be software controlled.
So I bet that's the lash up that Phil will use on his preselector/amp board.

One thing seems redundant or I don't understand the reasoning since I don't have the Atlas backplane, etc. though. There's a FPGA Altera Cyclone III chip on both the Mercury board and the Ozy board, both plugged into the Atlas.  Phil's has just one.  Is this for transmit capability via the Penelope board?

Sure like to see a pix of what you've lashed up so far; cabinet, etc.
Boy these things are fun. Did'ja see my "single" signal 5 ohm preselector/amp on Phil's yahoo board?

Rick,
I have not looked at Phil's board in a while. I did send him schematics of the tunable Cubic preselector. Bottom line the tighter the front end toe better chance you have to filter out the crud. I am in the process of wiring an interface board so my Racal will tune the Cubic preselector. I am very interested in doing testing on mercury when it arrives. Ozy is the communication interface to USB2. I'm sure this system has extra hardware not required for the stand alone RX. I hear there are FPGA software upgrades coming when Penny and Mercury live on Atlas.
Yes interesting times but the software pukes still have a way to go to beat a good old analog system. W1VD's data shows we have not really come that far in 40 years......just lighter to lug around.
