Some Interesting Filter Measurements

Jim Brown-10
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,

Jim Brown K9YC
