Hi all,
For those who have told me they're interested, I've attached a
PostScript file showing the "narrow CW" responses of two
ICOM IC701 rigs, measured using GoldWave and Matlab.
This is typical of the measurements I make.
My apologies if it's not appropriate to post messages with
attachments here - let me know if this is poor practice?
The file is 8.6 kB or so. Should view with Ghostscript, or print
on a Postscript printer.
73, Gary
