	I doubt that was the very first time you used Spectrogram.  I thought
about time I needed to search for the right webpages, download N0SS'
documentation, download and install Spectrogram on my computer, hook
up my soundcard to the K2 and carefully read through all 7 pages of the
documentation (CW only) before even getting to the calibration routine itself
and decided I could be finished long before that using only the K2, XG1 and
my head.  I also now know how to do this accurately in the field without a
computer.

	I'm sure Spectrogram is worth the investment in time to learn if you
need to recalibrate filters frequently, but it is NOT the only way to 
calibrate
them accurately.  BTW, if I were going to use a computer display to do this,
I would probably use K6STI's DSP Blaster instead since I'm already familiar
with it.  It has both waterfall and spectrum displays which can be used just
like Spectrogram to display audio output vs frequency...plus it is a very
versatile DSP program which is my primary use.
