[Elecraft] K3 Donald Duck 20 meters above
I'm making slow progress in getting my QTH ready for playing with the new rigs, and since I've experienced a problem with my K2 now sounding like Donald Duck on SSB, all bands 20 meters and above, I'm wondering if something went sour in a circuit, or if there's a simple realignment I need to do? After the initial alignment with help from an expert, it was doing fine, but I either bumped something while making a change, or fouled up a circuit. Does anyone have a simple solution, or is this a case of sending the box in for the experts, since I don't have time for days, weeks, or a month to figure it out. It was a surprise to be unable to clear up the USB voices one day, listening on 20 through 10 meters, then got excellent results on 40 80 meters! Now, the guessing and consternation sets in. Thanks for any suggestion aside from use as a doorstop or stick to CW only.

Re: [Elecraft] K3 Donald Duck 20 meters above
Ah, I think you're just describing SSB. It makes everyone sound like Donald Duck. OK, joking aside, I remember with my K2, there was a LOT of change in sound that happened during filter alignment. If the alignment parameters were off by just a bit the SSB audio would be dark muffled or thin and harsh. My guess is that you didn't have the filter parameters set quite right. With the K3, you have the option (which I took) of going factory assembled. No Donald Ducks in my rig. Of course, that is because I stick to CW only. :-) - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gil WA5YKK Sent: Friday, February 13, 2009 12:38 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Donald Duck 20 meters above I'm making slow progress in getting my QTH ready for playing with the new rigs, and since I've experienced a problem with my K2 now sounding like Donald Duck on SSB, all bands 20 meters and above, I'm wondering if something went sour in a circuit, or if there's a simple realignment I need to do?

Re: [Elecraft] K3 Donald Duck 20 meters above
Gil, The subject says K3, but the body of your post says K2. If it is the *K2*, what is the possibility that you have the USB BFOs on the wrong sideband? Or did you leave the internal counter probe in TP2 as many builders do and changed the SSB filter settings inadvertently while working with something else in the menu? Also note that the BFO used for USB on 15, 12, and 10 meters is the same as that used for LSB on the bands below 15 meters. You said 20 meters and above - does that mean you were able to hear USB signals on 15, 12 and 10 meters? If you were unable to tune 15 meter USB stations correctly, but can receive LSB on the lower bands just fine, you have something more wrong than filter alignment - and I can't think of what that cause may be. If you do have a K2 and are unsure of the filter alignment, you may want to check out my website www.w3fpr.com and review the article on K2 Dial Calibration - filter alignment is covered in part 3 of that article. 73, Don W3FPR Gil WA5YKK wrote: I'm making slow progress in getting my QTH ready for playing with the new rigs, and since I've experienced a problem with my K2 now sounding like Donald Duck on SSB, all bands 20 meters and above, I'm wondering if something went sour in a circuit, or if there's a simple realignment I need to do?
