Well, sign me up for a QS1R please. When do I send the payment?

Hi Larry,

I'll post more information on pricing and availability very soon. I'll probably create an "interest" list to get an idea of how many units to do for a first run.

[Will it be possible to phase lock the 2 receivers?]

Yes, there is provision for external encode clock input to drive multiple boards and the board was designed with that in mind. The AD6620 DDC chips also have sync capability.

This looks very good Phil. Congrats on a neat design. Keep us informed on pricing and availability, on both the receiver and follow-on transmitter.

Phil,

Any thought of using a QS1R as a 'scope?

Hi Phil,
Put me down for one as well please

I'm also interested but what is the rough price? £50 or £1000?

Larry said...

I'm certainly interested, I've been eyeing the ADC 130 MSPS part for some time now. Please add me to the list of interested parties.

Yes - this looks interesting but I think it all depends on the cost Phil. The specification looks great but if it ends up costing $1000 interest might be limited.

I am interested, so keep me in the loop.

Mike,

The QS1R will cost what it costs and the cost is yet to be determined. The most expensive component is the LTC2208 ADC.

Phil,

I'm interested, please keep me in the loop.

thanks, rob

I'm extremely interested in the QS1R. Kudos to you for leaping beyond most of the existing "open" projects, with a straightforward, integrated platform! As an SDR-1000 owner, I'm quite excited to transition to direct R.F. sampling. Well done. My checkbook's ready - name the price.

Hello Phil,
I am intrested in at least one.
Thanks
