I've stayed out of this thread and have only skimmed it but I'll weigh in a bit now.
I have very good hearing. I listen to my K3 using high fidelity headphones only - I never use the speaker. I operate CW only. My rig sounds very good. I do have the Radio Shack level control in-line with my Sony headphones (which are very sensitive) and if I run the volume all the way up on the in-line level control, I get hiss from the rig, but it has nothing to do with the K3. Every device I listen to with my Sony phones & the level control wide open (mixing boards, MP3 players, computers, stereo systems) produces hiss, and they all require AF gain be kept very low. Basically, since the phones are so sensitive, I'm listening to the inherent noise floor. The solution is simple. Throttle back the in-line volume control and the hiss goes away. Turn up the AF gain (to a normal level) and you get plenty of signal. Great sound, no hiss - That's my K3. - Keith N1AS - - K3 711 - -----Original Message----- My hearing aids do not have much response above 3.5 kHz. If I do not use the aids, my hearing drops off significantly above 1800 Hz although my low end hearing is about normal for the general population. I bow to those with better high end hearing than mine, but to me the K3 has no audio problems. Therefore I will make no further comments on this subject. 73, Don W3FPR ______________________________________________________________ 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
