Excellent Ken. May I add:
o High-precision frequency standard for the SDR-1000
o An overview of the source code; what the modules do and how they relate to
the other modules

The Orion is really two receivers in one box. While the

The Orion IF is about 15 kHz, the sample rate is nominally 48 kHz. Icom
products usually use a 30-ish kHz IF and 96 kHz sampling.
The SAHRC used in the Orion is the ADSP-21065L, which runs at ~60
MHz. ADI claims 240 MIPS, but that is becasue it

The Pentiums can run circles around these, but due to pipelining and so

sample-at-a-time like the traditional DSPs use, which may be part of the
reason the SDR1K has issues with lag/delay. The DSPs used in

OK, I was definitely operating under a misconception. Good.
The real advantage of the SDR1K is that the architecture is very open.
Yup. You can even feel the breeze blowing through it
