I spend 100% of my time operating CW and like narrow filter BW. Usually operate at 350 to 300hz BW, and often tighter, utilizing my 250hz filter. Today as I cranked down the Band Width, I discovered a 24 db drop in signal strength when the 250hz filter switched in. Went back and verified all the Config settings were correct. Filter is ON, Gn 4 db, Filter Frequency Zero (as per manual with 8 pole filters).
Can the filter go South for no apparent reason? Or am I missing something. When I switch the filter in line, I basically lose a signal, dropping 4 S units. The only other thing I've done is to align the Reference Oscillator with WWV after connecting a P3. Your input will be appreciated. 73, Art KZ5D ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
