I hope you are not trying to CENTER OP1 on 600 Hz. That's not right. You want the skirt to fall to zero around 200 Hz (left) and around 3K (right).
There may be nothing wrong at all. If you did center it, you'd have reception on both sides of zero-beat. Dan / WG4S / K2 #2456 <snip> The crystal filter passband will not adjust to center on a 600hz sidetone. As you adjust the filters towards 600 hz using Spectrogram (say OP1), the filter shape degrades and then severely attenuates the signal until NO audio signal is visible on the Spectrogram display. </snip> _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
