[Elecraft] Some Interesting Filter Measurements

[Jim Brown]

Crew,

I've just completed a bunch of FFT measurements of the IF and AF 
response of two FT1000MPs and a K3. They can be downloaded at    
http://audiosystemsgroup.com/FilterTestNotes.pdf

The usefullness of these data is to gain a better understanding of 
the relative performance of these radios, the various filter options 
that are available, and how to make the best use of what you have. I 
don't have a 250 Hz filter for my K3, but there are 250 Hz 8.2 MHz 
Inrads in two MPs, so I measured those to try to help me decide 
whether to buy one for my K3. And so on. 

73,
