Maybe you were >referring to FM sensitivity at 10 dB S+N/N? A much wider bandwidth is >used in that case. I was using SSB, 2.8 KHz for this measurement. -125 is the best the old HP8656B can do. At that level, the signal is solid, readily usable. I KNOW the MDS is way down from here, but I couldn't measure it easily. For FM, I didn't try the measurement. I was too busy with "fun with distortion" finagling. If I measure FM sensitivity, what would you expect (er, what did you measure in the lab)? I'll borrow an attentuator and a couple patch cables, and see where I measure the MDS using 500 Hz BW. Want to bet it's within spittin' distance of -144? :) I can repost with these results, but I will clear them with you and/or Eric first. The spec sheet doesn't show MDS. matt > >Wayne >N6KR > > ______________________________________________________________ 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
