[linrad] I-Q and HF SSB/AM/FM questions, bulk buy for 200Mhz SAW oscs

[Alex Crow <acrow@xxxxxxxxxxxxxxxx>]

Hi all,

I am new to the list and very new to linrad - I only installed it yesterday 
and am already bewildered by its (admittedly very cool) interface.

I am in the process of building an HF receiver based on the SDR-1000, see 
http://www.flex-radio.com which is a based on a Tayloe detector and produces 
I-Q signals at baseband, one going to the left input on my SB16 (yes, I know 
it's not great) and one to the right.

I noticed that Linrad has an SSB and FM mode with I-Q input, but I can't find 
any guide to using it this way. Does anyone have any pointers for getting the 
software tuned for SSB/AM and FM, and which controls are relevant for its 
reception once you're in the main window?

On another note, my design, as does the SDR-1000, requires a low-jitter source 
of 200MHz to clock the AD9854 DDS in order not to degrade its good phase 
noise performance. I have found a source for these (Epson QD, EG2121CA, 
jitter sub 5ps) but the price is a little high at 38UKP each. Does anyone on 
the list know, or have, anything as good as these at a better price? If 
others are interested in these I may be able to get a discount on more than 
5.

Cheers

Alex Crow
