Stumble is the right word for it - I hadn't thought about this. I would suggest that the DSP filter should have the "same" bandwidth as the roofing filter for this kind of testing. I'm a photographer by training and currently write software for TV graphics systems, so I am sure there are many on the list who might have more sensible suggestions. vy 73 de toby _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
