Re: [Elecraft] K3 microphone wiring ?
Barry, I believe the K3 comes permanently wired for the Elecraft microphones, and that means there is a resistor between 5 volts and pin 1 (AF). If one wants to use a microphone that would object to having that voltage present on pin 1, a series DC blocking capacitor should be used. My reasons to support those conclusions are the fact that Lyle said the K3 mic is wired just like it would be in the K2 with all jumpers wired straight across, coupled with the fact that the MH2 microphone is again being offered for use with the K2 and K3 - if it did not require the resistor, I would expect to see a change in the microphone numbering designation. 73, Don W3FPR Barry McWilliams wrote: Thanks for the additional information in the FAQ about microphones.

[Elecraft] Headphone Jack ???
A question for Elecraft, when y'all have time ;)) : It's a little bit of a guess looking at the picture, but the phone jack on the front panel appears to be a 1/4 type rather than the 1/8 size found on the K2, while the jack on the rear panel appears to be a 1/8 jack.

Re: [Elecraft] KNB2
David, To test, turn on the preamp and tap Q21 with a screwdriver tip - you can tell when the sharp 'clicking' with each tap is taken out by the KNB2. There is not a lot of circuitry on the KNB2, so I suggest that you check all the components for correct values, and in the right positions. Make certain the diodes are oriented in the correct direction. Look at the schematic and identify the voltages that will be present for the 2 thresholds (U3 pin 6) and the two pulse widths (U3 pin 7). If you have a logic probe or better yet a 'scope, you should be able to see if the one-shot is producing gate pulses (collector of Q4). Remember the most common cause of problems is the soldering followed by poorly tinned toroid leads and misplaced components - check these carefully as your first efforts, try to look at it critically as though someone else had built it. 73, Don W3FPR David N. wrote: Ok I have gone over my KNB2 Board twice now to see why it will not blank any noise.

RE: [Elecraft] KNB2
I'm offering this just on the off-chance you haven't tried it. Sometimes the noise level that roars out of the speaker with the AF gain turned up really isn't strong enough to trigger the NB even at low threshold levels. In that case, turning the Preamp On (and turning the audio gain down) often causes the noise to disappear! I wonder if your friend had his K2's preamp on and you didn't when you ran the side-by-side test? A lot of operators leave the preamp on all the time. The K2's design allows that to be done without any obvious problems in most situations.

Re: [Elecraft] loaded K2 vs K3
Why not have both?:) Actually, its all a matter of what features one needs most and the type of building experience wanted. K3 appears to have been designed to be the best competative full featured HF + 6M or contest rig possible that could be assembled, aligned, and repaired by the user from premade SMT circuit boards and components. SMT technology was necessary to achieve the high performance design objectives for the K3 wanted by the designers and requested by K2 users. The K2 was designed to be assembled from individual components and be the best possible portable QRP CW/SSB rig having the lowest electric power demand possible. The K2 design objectives limited certain features desirable for a base/contest rig, but it is still arguably the best rig for its intended purpose. Although the K2 has been found to perform unusually well as a base/contest rig, that was not its intended purpose as it is for the K3. The K3 should be better as a base rig as it did not have the K2's design goals limiting its performance possibilities for base rig use. The K3 should also be a good portable rig for Field Day type events where moving weight and the provision of electric power is not overly difficult. The KX1 and K1 are best for backpacking to distant remote sites using CW mode on minimal battery power. The K2 can provide greater TX power and performance features where it is possible to transport some additional weight and battery power as well as TX/RX in SSB mode. Although the K3 is not able to provide the individual component based construction desired by many, others will prefer the simpler construction for the user, or wish to forego building entirely. The K3 may be less user repirable than the K2, K1, and KX1 as replacement surface mount circuit boards are likely to be available only from Elecraft while the other Elecraft kits have circuit board components that are not only more user replacable but available, if necessary, from multiple sources. The K3 should be well ahead of other rig makers products when it comes to repairability as K3 users should be able to easily repair their rigs through board replacement and perform realignment. de KB1IKD -Original Message- From: [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Sat, 12 May 2007 8:56 PM Subject: [Elecraft] loaded K2 vs K3 Hope I've done the math correctly.

Good Evening, Another fine week has slipped past. The weather here in Oregon has really started to turn. My daffodils are almost done blooming. Yes, they bloomed for almost two full months. In the valley they've been gone for quite a while. This week finally turned ours into seed pods. There are a few left to pick for Pat so I'll get that done tomorrow before they are all gone. I took a long walk today off the edge of the property. There are quite a few strawberry and thimbleberry blossoms. I don't have a chance against the critters but I do hope for at least a few for myself. I saw some very large elk tracks on my trip. About eight inch diameter divots in the soil. They broke a very nice trail for me to hike along. I did work on 20 meters a couple of times this week and it went very well. A little QSB but not to the point of troubling copy; just noticeable. I have listened on forty a little but have been too busy to do much more than that. I've kept my solder pad quite wet for the last two weeks. I know I said I would do that over the last winter but that tree threw my schedule all out of whack. Maybe this winter will be more relaxed :) Soon the dry season will be here and with that carpentry season begins for me. It will be great fun getting this house repaired and my nephew trained in some new skills. First we get to move my radio shack, electronics work bench and shelves containing test gear, plus a few of the computers back to their old location far from the woodstove. Then we seal off the rest of the house and do some demolition. Once we can see the outside world we get to replace the entire roof from rafters, to sheeting, to drywall, to tc. After we strip off the covering I'll know better how much of the structure needs to be replaced. I may cripple in some framing if it's not too bad. Otherwise I'll replace it. Tomorrow there are supposed to be some showers here but nothing to interfere with RF propagation. The Midwest will have its normal thundershowers but hopefully they'll hold off until late into the forty meter net. If all goes well we can have a few relays around the worst of the storms to help hear one another. A few more dB would be nice so I can work into Florida unimpeded by very weak signals. Maybe I should look at different headphones with more sensitivity. That may prove the difference between good copy and a struggle to check you in. Tomorrow: 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Please join us: Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0200z (Sunday 7 PM PDT) 7045 kHz Kevin.
