Any Linux user that wants a good program for aligning the K2's filtrs should
go to www.baudline.com .. Baudline is a free Linux application that is every bit as good as Spectrogram, and may even do more. It certainly has the capability to display the same information that Spectrogram does for aligning the filters in the K2. I ran it in parallel with spectrogram using 2 computers, one running Baudline on Fedora Core2 Linux, and the other of course running Spectrogram version 11 on Windows 2000 Pro. They both showed the bandwidth properly and with sufficient clarity to be extremely useful filter alignment programs. Baudline seemed to have a bit better performance due to faster FFT's with Linux's smaller CPU overhead. Jim, W0EB K2# 4338 --- Outgoing mail is certified Virus Free.

I found this was also quite useful for zero-beating WWV when doing the frequency calibration of my K2 by tuning until the tone frequency lined up with the corresponding mark on the frequency display. 73, Bob N7XY _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
