Re: [Elecraft] k3:TX Monitor-some odd sound -beta?
Try sucking whistle rather than blowing and hold the mic away from the mouth. Works for me David G3UNA Guy said: Whistling is usually 20-30 db louder than your spoken voice. That's why people whistle when a shout doesn't make it. Takes a practiced whistler to whistle softly.

Some people always want to believe they magically have the only FT1000 series radio that never had severe keyclicks. They get a little defensive to the first few dozen complainers until it sinks in that every Yaesu made for a number of years had a bad problem, and there were no factory exceptions for any of the FT1000 series. It's more a matter of denial in most cases. It also can be related to other parts of the system like switching times on amplifiers, non-linear (or class C) amplifiers on CW, or bad connections in antennas or cables.

Re: [Elecraft] k3:TX Monitor-some odd sound -beta?
Hi Bill Yes, I was using headphones. I will do further tests with the internal 2 tone generator and see if I still get the oscillation. Unfortunately I have very good hearing so every pip and squeak I can hear. Even with the sidetone running I can hear that mysterious relay resonance when keying. If Elecraft releases a mod or update I may try that at a later date. In the meantime its of no consequence to me. I was unfortunately spending a lot of time trying to EQ a mic and thats why I noticed the artifact. 73 John --- On Mon, 5/3/10, Bill W4ZV btipp...@alum.mit.edu wrote: From: Bill W4ZV btipp...@alum.mit.edu Subject: Re: [Elecraft] k3:TX Monitor-some odd sound -beta?

With the Gate off EQ flat MH2 hand MIC TX test mode Band 7mhz While whistling there is a odd artifact. If I whistle I get a sound that sounds like a oscillator pulling in a receiver. I dont get any odd sounds with normal voice testing .With a continuous whistle I get this artifact that is a mirror of the whistle, however it seems to shift frequency or pull the louder you whistle.It might be a IMD product? I have never noticed this before in the K3's monitor. I will also check the clubs K3's and report back. Anyone else get this? Are you using headphones or the internal speaker? If the latter, physical microphonic modulation of the VCO can cause spur artifacts. I've never experienced this because I never use the speaker, but I've noticed it on CW signals from other K3s. The audible PITCH tone can modulate the VCO causing spurs at +/- PITCH setting. I suppose the same could happen in SSB if MONITOR volume were high enough. Elecraft has a stiffener/damper fix for the VCO board if this is the problem you're having. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/k3-TX-Monitor-some-odd-sound-beta-tp4997305p4998207.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 __ 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

Re: [Elecraft] [K3] Bad COM port made K3 not work
W5JAW has a click free MP but he says making it totally click free required much more work than just the common modifications - the fix included a multi-stage ALC modification. Two comments from Jim: As I told you some time back, I worked real hard on optimizing the keying waveform on my rig. It's as close to optimum as I could get it; the result is Gaussian in shape. Very narrow bandwidth, yet still clear copy up to 100 WPM. Due to the messy way that Yaesu implemented the keying, it was necessary to modify several stages of the IF string to achieve this without screwing up the QSK operations. and: Re: Key click mods: The W8JI mod does help a lot, but is far from optimum. Much better than nothing. Because it depends on a simple RC filter on the gate of a MOSFET, it provides a very asymetrical wave shape. Also, since the transfer characteristics of the FET vary widely, the rise/fall times do too. Also, I still enjoy QRQ operations, with QSK, and these simple fixes don't work very well for that. The other problem with these rigs is that even with good wave shaping, there can still be a significant thump on the first dit of a string if there has been a 1 second delay or more since the last character was sent. This is due to the way the ALC works. The power level is controlled by setting a threshold in this circuit. The attack time is very fast, and will create a click, even with earlier waveshaping. I solved this by decoding the CW mode from available logic levels, and then, when in this mode, biased the ALC input just below threshold level. This makes the first dit after a delay look same as any following. I can always tell when someone is using a 1000mp with a simple click fix. No clicks except at the start of a new word.

Re: [Elecraft] [K3] Bad COM port made K3 not work
Oh I was wrong. In this case this is very good information. However I guess since the mod is as I understand it quite extensive not too many will do it. I hope W5JAW will spread the info on the mod.

[Elecraft] Inertia
So, the CNC'd K3 tuning knob arrived over the weekend. I's a very very nice piece of work, and regardless of the endless PM-ing about the price, it's in line with other such products. But this isn't about knobs, and I'm not trying to start another endless twitter-like thread on the subject, although the subject does seem to be lurking just below the surface of every ham's conscious. It's about inertia. Yes, of course it's heavy and it does spin nicely. At first I wasn't so sure I liked the feel and I went back and forth on the thing quite a few times. But the more more I use it, the more I think it's going to stay on the radio. So back to inertia -- an object in motion wants to stay in motion. And, an object at rest doesn't want to jump up and get going, either (like me in the morning) -- which is where an advantage is that didn't come up in the 4,763 or there'bouts posts on knobs. I like a VERY free running control. The inertia of this thing is such that a little bump here and there doesn't jar the tuning half-way down the band. Well that's a bit of an exaggeration of course, but the point is that even with virtually no friction against the felt pads, a delicate touch is not required to keep it in one place once it's put somewhere. Inertia is your friend. I do worry (a negligible amount) about what the increased weight might do to the panel bushing over time, but time is still along way off and bushings are not an endangered species :-) YMMV Grant/NQ5T __ 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
