Gentlemen,
Yet another input to the story. I just completed some tests to measure
the actual bandwidth of a modified IF strip. What I'm getting is a
6-to-60 result of <8 kHz at 6dB down, and t <28 kHz at 60 dB down. This
comports with the data Ken sent showing an expected bandwidth of 14.6
kHz (twice 1/2 bandwidth shown in manual chart)) and 52 kHz (again,
twice the noted bandwidth) for a "new" receiver. Even with that, it
looks like a winner. I'm writing all this and how to do it up for ER,
at this time. If any of you all have comment, please let me know. I
believe I'm interpreting Table 8, page 56 of manual AN 16-30ARC5-2
correctly. Its just that they specify a half bandwidth factor, inasmuch
as their measurement procedure yields such.
