K2 filter alignment

All,

I was trying to do EME yesterday and today w/ Arecibo and realized my filter
alignment is horrible. I did this years ago following the spectrogram
procedure but it is not right.

The computer I used for this is long dead, and I get a bad link to
spectrogram when I follow the Elecraft link.

Does anyone know where a good copy is?

Tnx,

Ed wa3drc

Re: K2 filter alignment

Hi Ed

Would another FFT program be suitable. Once I get the K2 I have here up and
running
my intention is to use a program such as Spectrum Lab or Spectrum2000, the
former
is my preference.

Re: K2 filter alignment

Sorry just realised that the program I meant was Analyzer2000

The URL's for both packages are below

Ed,

You can find details of how to do the filter alignment using Spectrogram
on my website www.w3fpr.com - it is in Part 3 of the article on K2 Dila
Calibration.

Tom Hammond N0SS also has information for using Spectrogram on his
website www.n0ss.net. Tom also has version 5 of Spectrogram available
as a download from his site.

Nidge,

Yes, you can use most any application that will give you a spectrum
display. Some do not provide the features I constantly use in
Spectrogram, such as the presence of 2 frequency markers that extend
from the top of the display to the bottom, and the ability to place a
third marker as a crosshair anywhere on the display - those plus the
current cursor position give me the use of 4 markers, and the amplitude
display occupies more space on the display than several others I have
tried. But the real answer is YES, you can use any of them, however Tom
Hammond's "how to use for the K2" documentation only applies to
Spectrogram version 5.
