Re: [Elecraft] K3: switching on click
I confess that it never really bothered me until I started to use external speakers, and when I use head phones the K3 gets turned on before I put the headphones on. I bought the K3 a couple of years ago, it's #980. Maybe something in the hardware has changed since. It's no big deal, I was just curious as to what others thought. 73, Stephen On 4 September 2011 19:41, Torrey Mitchell torr...@q.com wrote: I near nothing but the soft mechanical click of a relay before the audio appears at the speakers.

Re: [Elecraft] K3: switching on click
Hello Stephen and others On K3 turn on, I hear two clicks on the speaker before the display turns on (not the relay clicks).

Re: [Elecraft] K3: switching on click
I'm using amplified speakers too, and also plugged into the stereo speaker jack. I'm hearing far more than just one pop, but about 4 in total, one before the relays start switching and then the other pops/clicks over the next second or so, even with the AF gain on the radio turned down to minimum. Clearly I seem to have a more severe case than some, but I'm not worried about it, just curious. As Ramiro said, it doesn't match with a quality radio. If I had a motorbike though, I'd rather it sounded like a Harley than a Honda!! Changing the subject completely, I just worked 5B4AIF on 21MHz ssb (very rare mode for me!) on 100mW output to a doublet. At least the mojo is still working!! 73, Stephen On 4 September 2011 20:17, Sam Morgan k5oai@gmail.com wrote: I hear clicks also but they are directly from the K3 like relays getting themselves set where they should be then I hear one pop from the amplified stereo computer speakers I have plugged into the stereo speaker jack in back GB 73 K5OAI Sam Morgan On 9/4/2011 2:06 PM, Stephen Prior wrote: Hi Sam That does make a difference, but there is still a pronounced series of clicks over the second or so it takes the K3 to boot up.

If you haven't read the book, it's a fine read, in fact as it says on the cover, it changed my life! Agreed: the K3 attracts radio amateurs who are in pursuit of quality in that special sense which Pirsig spends half the book explaining. I thought Elecraft genuinely understood that, but as the K3 has moved into mainstream production with so many of its initial problems still unaddressed, I'm becoming far less sure.

Re: [Elecraft] K3: switching on click
I have external speakers connected through the headphone jack and have zero snap, crackle or Pop :-) Just for grins, I moved the output to the line out jack and did create the Pop on turn on. Without the external setup, I do get an internal speaker pop, but nothing objectionable. With stereo output to amplified stereo speakers when plugged into the external speakers or the phones jack on the front panel, I don't get any POP. Therefore, to remove the pop with the internal speaker, plug into the external speaker jack or the front phone plug... I guess... ;-) 73, Bill K9YEQ -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Robert Redmon Sent: Sunday, September 04, 2011 3:17 PM To: Torrey Mitchell Cc: 'Elecraft' Subject: Re: [Elecraft] K3: switching on click Stephen, you make a valid point.

Re: [Elecraft] K3: switching on click
Mike, If you are using amplified speakers, that difference is to be expected. I use unamplified speakers, and all that is heard is a muffled couple of pops - it is not in the range of anything annoying to me. You are hearing the large value capacitor in the AF output charge up (the capacitor is not as large in the headphone amp in the K3, and the amp is a different one). The K2 does the same thing - and at my workbench I do use amplified speakers - yes, it can be annoying with amplified speakers. 73, Don W3FPR On 9/4/2011 4:46 PM, Mike wrote: The external speakers have a pretty loud pop at power on.

Re: [Elecraft] K3: switching on click -- One wonders...
I suppose the click - or in my case a thump - depends on the timing of the mute signal from the controller and the value of the bypass capacitor on pin 8 of the speaker amplifier. The chip manufacturer recommends 10 uF for the bypass capacitor but I notice that Elecraft use 3.3 uF in the K3. The manufacturer's data sheet shows: Cb (uF) Ton (Ms) 1.0 120 2.2 120 4.7 200 10.0 440 The manufacturer's data sheet also calls for the time constant of the input coupling capacitor and Ri+Rf (input and feedback resistors of the amplifier) to be less than the turn on time set by Cb. In the K3, I don't know how critical the ratio of input time constant to turn on time is but the reference design has an input time constant less that 5% of the turn on time while in the K3 the input time constant is about 30% of the turn on time. In addition, I suspect there may be some variation in early vs. late production due to the change in the DC resistance of the RF choke in the DC line feeding the speaker amplifier. 73, ...

Re: [Elecraft] K3: switching on click -- One wonders...
Hi All! I know we've milked this one quite a bit, but I do have a point to make that I think will frame this power-on thump issue in a little better light... First off, I have K3 #3019 and there is a very detectable power-on AND power-off thump in the built-in speaker and in the cans. I don't have external speakers so I can't say about that. BUT, what I wanted to point out is that this behavior, this power-on and power-off click or thump is widespread and not strictly a K3 problem. While there are others on this list with way more experience in the field of audio, I can say that in my younger days I was very much an audiophile. I can tell you with certainty that all the high end audio equipment I owned (and wished I owned!) thumped when powering on and powering off. Outside of my own equipment, I have worked mixing boards and commercial sound systems which all thumped on power-on/off. Some loud enough to nearly blow your hair off. I have even witnessed this in concert halls -- I'm thinking, as one example, of the Pacific Amphitheater one night in LA which very clearly had the power-on/off thump. I can think of others probably if I worked my brain cell really hard. The point is that this phenomenon seems to be part and parcel of the powering-on and powering-off of solid state audio amplification. As this exists in the high quality and commercial equipment I've had the pleasure of working with, I don't feel it detracts from the K3. I think the K3 is actually in pretty good company. I know that being common doesn't make it right...but it probably does indicate that most in the business don't regard it as particularly important. IMHO if it costs more than a nickel to fix, I wouldn't bother. However I understand that others, perhaps with amplified speakers, are well within their rights to feel differently. :-) Alrighty then...back to the honey-do list... 73 Aloha, Dave AH6TD On Sep 4, 2011, at 12:25 PM, Joe Subich, W4TV wrote: I suppose the click - or in my case a thump - depends on the timing of the mute signal from the controller and the value of the bypass capacitor on pin 8 of the speaker amplifier.

Outside of my own equipment, I have worked mixing boards and commercial sound systems which all thumped on power-on/off. Some loud enough to nearly blow your hair off. I can think of a fair number of power amplifiers and mixing board monitor amplifiers that include *delay relays* in the speaker lines that leave the speakers disconnected for two to three seconds after power is turned on specifically to prevent the thump (and potential damage to speakers and/or hearing). 73, ...
