Ralph, The K2 was designed for low receive current consumption, and as a result the audio power had to be limited. With the K2, that was a common complaint, particularly for hams with hearing loss (me included).
Not so with the K3 which has a 3 watt audio amplifier. Either you are using inefficient speakers or you have something wrong there. Do you have a mono plug in the rear speaker jack? It must be a stereo plug (a stereo to mono adapter will not do, it still shorts out one channel). If you have a stereo plug, do you have it wired correctly? For a single speaker, it must connect to the tip and the shell. If you are using 2 speakers, one connects to the tip (left) and shell and the right one connects to the ring and shell. If you are using 2 speakers and are listening to the same signal on both, are the speakers phased correctly? (try reversing the connection to one speaker) - that would be more apparent when the speakers are moved closer together. Out of phase speakers produce acoustical cancellation and will give the appearance of low audio when in fact the level can be quite high. Other than a fault with the K3, that is all the "dumb" things I can think of right now. 73, Don w3FPR On 11/18/2011 3:21 PM, Ralph Parker wrote: >> does anyone have the same problem with low audio on your K3 > >from both my speaker and headphone? > > My headphone output is OK (AF gain at 9 o'clock), but my speaker output has > always been low (sometimes requiring full AF gain) regardless of config > setting or internal/external speaker. > Others tell me it's 'normal', but I don't believe that for a minute. > I've learned to live with it, but I don't like it. > > Ralph, VE7XF > ______________________________________________________________ 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
