I wonder if your noise generator has a bias toward low frequencies, or if there's some frequency-limiting component in your measurement. Do you have the KDSP2 installed? Did you disable it when you were taking your measurements?
---------------------------------- Taking audio from the "phones" jack can produce a rolloff much like that as well, caused by the electrolytics in the circuit. The auxiliary speaker jack is a better choice. Ron AC7AC _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
