I used it on about 15 contacts yesterday, 20m .. What I "saw" on the readings were every Report which was generated was >= +30 . What I "heard" was that all the adjacent QRM crud was non-existent. In fact, using "Shift" I could eliminate one of you guys 20hz away in a legitimate QSO and still decode and get the +30 reports. So I posited a question to the academics which revolved about the notion I had that "If" the sig-rep is really +30, here, in the mind of the JT9-Genie inside my Win7 machine, then that should mean that I could also hear down to the typical level of -25 and decode. So, my non-Professor of Radio Astronomy brain decided that a guy running 5 watts from France, who was getting +30 from me, should be able to reduce power 20 db, and I should be able to decode him .. well, or her, but I dunno any French Amateur Radio girls ennaweh, so "guys" stands. However. it's a real Juggle for me, the Newbie-K3 driver, to try and balance all the 4 to 6 setting possibilities and wind up with a visible trace. I won't believe this is actually making weaker signals possible until I have somebody systematically reduce the output power on his end of the planet while i write down the sig-reps. 'Doubting Thomas' you say? Ey-yup, true. -- Best regards, Bob KD7YZ Win7-64bit + K3 BTW I wish they wouldn't make the List-Emails auto-reply to original person only .. seems a lot of useful info in the answers will never get to the general populace. I only caught the reply-to address at the last second B4 Sending .. way too much trouble to re-address these. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
