[Elecraft] K2-KAF2 up and running

[Robert Tellefsen]

Hi Fred
I used one before I put the KDSP2 in my K2.
The KAF2 will work best if you keep signal
levles into it down and use more audio gain
after the filter.  I seem to recall there is some
way to adjust gain in the filter, but I forget just
what it is.  Where you have enough signal
strength, you might benefit from using the
attenuator or just straight in.  You may not
need the preamp except on the higher bands
where signals just are not strong.

If you have Spectrogram 5.1.7, be sure to use
it to carefully match the AF filter to the crystal
filter passbands for the best results.

Good luck and 73
