[TowerTalk] receivers for HF phased array

[kb5my@starband.net]

What about using multiple copies of the RX-only version of the SDR-1000? 
Built & tested for $899 each, Analog Devices DDS LO (no PLL or VCO), I/Q
output, $10 option to add capability for locking to an external 10 MHz or
20 MHz reference, and the software written in C# (C Sharp) is open source.
 You can tweak it to your heart's content.
