[Elecraft] [P3] Reference level; scale

[Wayne Burdick]

Hi Al,

Note that the P3 was designed by a former H-P engineer :)  Alan Bloom  
(N1AL) is our newest staff engineer and an expert in RF test equipment  
design. He's also a heavyweight technical contributor to the ARRL  
Handbook.

Another of our engineers (Bob, N6CM), a real stickler for signal  
processing performance, recently tested the P3's FFT and signal chain  
accuracy. Using the best test gear available, he found that the P3  
performs as well or better than most laboratory spectrum analyzers. To  
quote Bob: "I'm beyond impressed." He doesn't say this lightly.

We believe that the P3 will set a new standard for stand-alone  
panadapters.

73,
Wayne
