[Elecraft] (phase signals RE: SDR IQ/IF Questions

[John Ragle]

The URL posted by Mr. Thornton is part of an excellent mid-level 
tutorial series, quite worth reading.

I wanted to mention, in this mix, another SDR which seems to be somewhat 
unknown in this country; /vide/ http://www.rfsystem.it/shop/... This 
receiver "PMSDR" has T/R switching, covers up into the VHF region, and 
is physically very small and available in kit form. I had one of the 
early models, and was quite pleased with its quality. In its newest 
form, it can serve as a stand-alone unit or as a panadapter with, for 
example, the K3. I believe there is a US/Canadian dealer.

QST's articles do not demonstrate any particular expertise or breadth of 
knowledge in this field.
