Re: [Elecraft] (K3) APF and selected bandwidth
(BTW I wrote the following ~3 years ago before APF was changed from HOLD to TAP on DUAL PB): ## I use APF virtually all the time and never use RIT, SHIFT, etc. Just HOLD DUAL PB to actuate APF and use the VFO to zero beat. COARSE (10 Hz) VFO steps is usually close enough but you can switch to FINE (1 Hz) if necessary for ultra weak signals. I also strongly endorse N6KR's suggestion below: "I suggest setting the passband width to about 250-300 Hz when using APF." This is extremely important since bandwidths too narrow will introduce additional ringing to the APF which already borders on ringing. I actually use a 200 Hz XFIL but set to actuate at DSP 400 Hz. With WIDTH set to 400 Hz, the signal first goes through the relatively broad (4.0 shape factor) 200 Hz XFIL, then a 400 Hz DSP and finally the narrow APF. This makes the cascaded XFIL/DSP seem more like 250 Hz, reduces ringing, still allows you to hear off-frequency callers (although attenuated) and helps your ears discriminate weak signals from noise by providing a wider background sample of noise. ### The last phrase "helps your ears discriminate weak signals from noise by providing a wider background sample of noise" is key. Narrower bandwidths are not best for the human ear/brain...no matter what theory says about narrower bandwidths having better S/N. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-APF-and-selected-bandwidth-tp7623407p7623455.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Speakers - Optimal Frequency Range?
Your logic is good, as usual. But let's look at the physics of loudspeakers, which I tried to do on an earlier post. A SMALL diaphragm has better dispersion of high frequencies, while it doesn't produce loud bass. We don't need loud bass, so a GOOD small diaphragm loudspeaker is what we need. And that is EXACTLY what Elecraft uses in the K2 and both versions of the K3. The late Dick Heyser famously said that "trying to describe an audio device or system using only frequency response is like trying to write Shakespeare with only one word in your vocabulary. In addition, to have any meaning, a frequency response spec must include +/- dB limits and it must include angular dispersion. VERY few consumer loudspeakers do that -- they simply quote upper and lower limits. Many cheap loudspeakers (and headphones) have very bumpy frequency response, and those bumps create phase distortion that degrades speech intelligibility. So, to repeat my earlier advice, the best loudspeaker for ham radio is one that has smooth response from about 300 Hz to about 3 kHz and has wide, uniform dispersion within those limits. In other words, it sounds the same both on and off axis. Loudspeakers that cover a wider frequency range are FINE, but don't pay extra to get one. A loudspeaker with wider response would reproduce lower lows and higher highs, but our ham rigs (at least the good ones when well adjusted) limit audio to a range of about 300 - 3,000 Hz in the IF. There is no good reason to buy a speaker rated for 300 - 3,000 Hz. What we want is one with good performance within that range, and most that do will have at least another octave or two above and below those limits. (An octave is 2:1 frequency) BTW -- I purposely set my RXEQ flat because I primarily work CW, and I want to hear the off-frequency signals that may be very low or very high in frequency, and I limit frequency response on SSB with the settings of my IF filters. 73, Jim K9YC On Sun,10/16/2016 10:44 PM, Dave Cole wrote: So, as I said in my original post, it is the most efficient use of the hardware is to use a limited response speaker. No need for high end stereo speakers on a K3... That said, I may put on some better speakers on my K3 because in the long run it is a bit less stressful on my ears...:) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

To reset the Waterfall Height on the external monitor, I need to go to the P3 Waterfall Height, make any change in the Height value, and then the Waterfall Height on the external monitor corrects itself.

Re: [Elecraft] Speakers - Optimal Frequency Range?
I have spent may years in “hi end” audio… some building some selling some just fooling around. Does wire matter? is there a difference between tubes and soild state? Can I hear 20K? does it matter if I can’t hear 20K? Why build a wide band amp if you can hear it? All these questions really don't matter one bit. The ONLY question the listener need ask… Do I LIKE how it sounds? That's it folks, no more no less. Simplistic… yep sure is. A few years back I was attending an audio show in Denver with a few “audio” friends. We would typically visit different rooms together and give a listen to the various systems in each room.

Re: [Elecraft] K3S QST Article
Well one of the main reasons I love my K3S is because of weight (or lack of it). Due to back problems, I cant move that 40-50 pound rig to the bench to do any adjustments, repair, etc. I can take my K3S to the beach house with ease and have a nice 100 watt radio. Each of us has their own needs and wants in a radio and a 60 pound monster with 200 watts and built in power supply for 48 -60 volts, may not be one of them.

OK. Everybody ready to go out and buy a 28 volt power supply for the new K3S? The range of 12 volt supplies is way, way broader than 28 volt. The Astron LS35M 35A@28VDC is 380 dollars. Oh, a built-in? Where does it go in the case? And does the K3S add an internal inverter to produce 12V for everything else from the 28V? Lot of expense for a small improvement that they can get with a freebee change to a late developing gift improvement for the cost of shipping. What would be a practical way to actually introduce such a change? Lay out all the specifics involved. Let's see your critical path item by item plan.

Re: [Elecraft] Speakers - Optimal Frequency Range?
Wow Phil, right on. My first career was a buyer for an audio chain. I listened to everything they brought in. My assistant and my secretary and I NEVER agreed on what system sounded best. I would think a speaker that is reasonably flat from 200 hz to maybe 5khz with low mechanical distortion and good power handling would provide a decent baseline. After that - your warm tones are my screeching trebles; your full bass is my headache- inducing low range. I use a quality, small bookshelf speaker and then use the K3's equalizer to make the sound fill into the peaks and valleys of my ear's response curve. $50 would probably net you a pair of small Sony, Polk, KLH, JBL or even Pyle. New or used - you can't beat a nice rigid box with a woofer and a tweeter. Other interesting options are line-out to a Bluetooth audio source and then to one of the many Bluetooth wireless speaker systems. Or to a small stereo hifi amplifier. The K3 has stereo line output - a nice pair of bookshelf speakers left and right would definitely give you the best sound the K3/K3s is capable of producing (especially the K3s or an upgraded K3). A good audio setup will amaze you when you talk to another properly adjusted radio with a good microphone. There is a very broad range in the quality of signals on HF SSB. From dreadful to beautiful. I recommend setting up your station for the very best receive quality your radio can produce - which in the case of the K3, is substantial.

Re: [Elecraft] Speakers - Optimal Frequency Range?
I definitely agree with using good quality headphones for optimal listening. But, headphones are a different psycho-acoustical experience than a speaker system. Personally, I prefer to listen to a speaker system. Headphones VS: Speaker system will be different for everyone. But, if you prefer speakers, i recommend decent quality components to give you the best your "K" brand transceiver can deliver.

Most recording studios have a pair of high quality loudspeakers mounted on top of the console for exactly that purpose. They also have a larger pair that DOES excite the room. I dread to think we'd require anechoic chambers for Hamshacks! Anechoic chambers are TEST environments, they are lousy listening environments.

Re: [Elecraft] Speakers - Optimal Frequency Range?
OK, I know this thread is getting too long, but… When my beloved Grado SR-60 headphones died, I used my Yamaha CM-500 phones for music. They were terrible. Not even good enough. So I ordered Grado SR-225e phones. And the cord for the SR-60 phones is part of my PTT hand switch. The CM-500 phones are back with the ham rig. In general, good hi-fi reproducers should be good communications reproducers. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Oct 17, 2016, at 9:18 PM, Doug Person wrote: > > I definitely agree with using good quality headphones for optimal listening. > But, headphones are a different psycho-acoustical experience than a speaker > system.
