All: I understand the potential RFI issues and in fact have had to try different grounding schemes and #31 ferrites to eliminate the issue with my powered speaker.
Call it a personal preference but when another person is in the shack and I want to use headphones, it is nice to have individual control of the speaker and HP. I could always add an amp to the SP3……. I’ll just order an Elecraft knob for the pot… Russ KD4JO PS - Back to the original thread name ☺ From: Charles R.Tropp [mailto:charlestr...@yahoo.com] Sent: Tuesday, September 13, 2016 6:31 AM To: Russ <mundschen...@msn.com>; Elecraft <elecraft@mailman.qth.net> Subject: Re: [Elecraft] Trump's a bigot - Hillary's a crook!! Hi Russ, I am not sure what problem you perceive in the failure of the SP3 to amplify it's signal allowing you to individually change it's volume setting. As some say, "this is a feature - not a bug" as it prevents possible RFI interference from a nearby transmitted signal. Volume on the K3 is controlled by the AF knob. Is this not all you need? I mostly work CW and use my headphones for that purpose. But sometimes, I am doing something else and would rather just listen to the speaker. I rarely adjust he AF knob and yet, I can hear CW throughout the house when the speaker is on. I use my K Pod to instantly switch between headphones only or headphones and speaker. All this is controlled by the configuration menu settings. I think you will enjoy the SP3 Russ, and if you buy two you can have stereo! 73, Charles N2SO Treasurer, Quarter Century Wireless Association, Inc. http://QCWA.org<http://qcwa.org/> On Monday, September 12, 2016 9:17 PM, Russ <mundschen...@msn.com<mailto:mundschen...@msn.com>> wrote: Now that I have your attention - off topic subjects get the most airtime it seems.... Here is an on-topic question - thanks!! I currently feed a powered speaker with the constant line output of my K3. I can individually adjust that speaker's volume locally and the HP volume on the K3. I'm contemplating the purchase of an SP-3. As this speaker is unpowered, I will have to use the K3 power amp and am afraid that I will lose the individual volume control versatility I have. If this is the case - would it be possible to repurpose the sub-rx (I don't have one) AF gain "ring" to control the speaker amp level. My understanding is that the speaker out and HP out's are fed by separate DAC's.
