I finally got around to using Spectrogram to align the filters of my 8 month old K2 and completed the final checks for the KSB2 and KAF2. When using the birdie at 7.000 mhz and selecting either AF1 or AF2, the volume of the birdie increases greatly and sounds almost distorted. Same with received signals so that when switching between no audio filter and AF2, I have to decrease the AF control. I searched the archives for a similar question and could find none. In the instructions, I read "the RF signal should be clear, distinct, and slightly louder when AF2 is selected." Slighly louder than what: AF1? In my case, it's a little less than AF1 but a whole lot louder than in the OFF position. Do I have it aligned incorrectly? Adjusting R1 and R2 for a maximum seems so simple I don't see how to mess it up! Right now, due to the huge change in received signal level when switching in the filter, I'm not using it but sure would like to ! Anybody else see this problem? 73 de Clark ke4rq _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
