[Elecraft] Raspy audio from K2
I recently finished building the KSB2 and did the alignment on the filters. Everything seems to be working as advertised, except on transmit my voice sounds raspy. I haven't had time to dig into the problem yet, but I did try 3 separate mics and got the same result. For my test, I transmitted at 1 Watt into a dummy load while listening on my Icom 706 with headphones. My first assumption is that I simply need to tweak the transmit filter, but I'm asking if anyone else has had the same symptom that was perhaps caused by something else. For example, is it possible the two radios are simply too close to each other for a good audio test? They are on separate supplies and were about 6 feet apart during the test.

[Elecraft] KDSP2 questions
I'm enjoying the KDSP2 module in my K2. It is the most effective audio DSP I have used. I have some questions, though. 1.) The filter C1, or c1 comes up on the menu as a lowpass filter and seems to be fixed. Can it be changed to a bandpass ? If so, how ? The manual is not clear on this. What is the cutoff frequency of this lowpass filter? Is this cutoff frequency adjustable? 2.) Referring to the KDSP2 Manual, page 38, troubleshooting: The middle of the page gives the following symptom (which I experience frequently): AFIL works but I can't access DSP or clock menus when I press Display The manual goes on to suggest turning the K2 off then back on. This works for me, but is there a better fix for this? The manual also says to let us know if this happens frequently. I have e-mailed Elecraft support regarding this. 73, Chuck NI0C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Hi John, one possibility is that the transformer of the power supply is too close to the K2, try some additional physical separation and see if that does the trick.

[Elecraft] Solvent
Hi Folks, I'd like to know from the collective wisdom what solvent may be used on Elecraft PC assemblies to remove some residual flux and flux smears. It seems to me that a solvent that wouldn't harm boards and components was isopropyl alcohol (rubbing alcohol) in the old days. What do you Elecraft Builders use!

[Elecraft] Solvent
Bill: I use denatured alcohol and a commercial spray-on flux remover. Both seem to work about equally well for me. Denatured alcohol can be found at any hardware store, of course, and is cheaper than the flux remover. I apply alcohol with a small brush. In some cases, a cotton swab is useful, but you tend to get cotton fibers snagged on component leads, so if you can find them foam swabs are better. The problem with isopropyl alcohol that you purchase at the drug store is that some contain extra ingredients that can leave a residue on your PCB. The electronics supply house I frequent sells electronic grade isopropyl for board cleaning. I have not found any problems with damage to plastic components, but obviously a test should be made if you have any doubt. And, of course, keep it away from the LCD and diffuser. (don't ask me how I know about that.) Jack K8ZOA www.cliftonlaboratories.com home of the Z90 digital panadapter William M.

Re: [Elecraft] Solvent
There are/were many flux removal chemicals available, but in today's over-protective society they're hard to find. I treasure my stock of triclorethelyne (SP?). (:-)) Rubbing alcohol and a small stiff brush work well. I place a paper towel on the board, between the brush and the board, to soak up the freed resin and prevent it from running all over the board. An ideal brush is known as an acid brush and is available at welding supply stores. It has a rolled sheet metal handle and stiff bristles that can be cut to shorter lengths to make the brush stiffer. A fist-full of 'em is cheap. In other stores they may be sold as glue brushes. 73!

Re: [Elecraft] Solvent
If you go to the drug store and look closely you can find 91% isopropyl alcohol. The remaining 9% is water which won't hurt anything.

RE: [Elecraft] Solvent
I'm sure others will suggest many options although if you read the Elecraft manuals you'll find, in bold type: DO NOT use ... solvents of any kind. Use of any of these will void your warranty. If you need to clean your boards you're probably using too much solder. Try a smaller diameter solder. If you look at the photos of assembled boards in any of several Elecraft assembly manuals including the XV 50, 144, 222 or 432 transverters, the KX1, the T1 antenna tuner or the WM1, AT1 or AF1 mini-modules, you'll see boards I built up while writing the assembly procedures for those kits. Those photos are the boards as they came from the soldering iron. If you look closely, you might see a few dark spots of flux here and there, but they're tiny and insignificant and often in a place where I installed and removed a part several times as the design was finalized. To be certain the kit can be built exactly as described, I never use any tools that are not specifically listed in the manual. That means no fancy high-powered vacuum desoldering tool to clean up pads; just braid or the SoldapulltR sucker listed under Tools Required. I will admit to taking a small swab with some isopropyl alcohol to an individual, particularly messy solder pad when I needed to re-shoot a picture after many component changes, especially when, after many resoldering, some flux escaped the pad itself and ran onto the PCB, but that's the extent of any flux removal. I moisten a Q-tipR or similar swab with alcohol, then place it on the flux and spin the tip to scrub that spot and loosen the flux.

RE: [Elecraft] Solvent
I wouldn't clean the boards. I didn't on mine. If you do, with alcohol, be sure not to use Completely Denatured Alcohol. It is a serious poison and can be absorbed via your skin. It contains brucine, very nasty stuff. Be careful. I'm sure your boards will be fine if you use good solder and solder carefully. pete, kn6bi -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Doug Faunt N6TQS +1-510-655-8604 Sent: Wednesday, December 13, 2006 10:08 AM To: [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Solvent At least around here, 99% isopropyl is readily available, and is only slightly more expensive. 73, doug From: Jim Miller [EMAIL PROTECTED] Date: Wed, 13 Dec 2006 12:30:24 -0500 If you go to the drug store and look closely you can find 91% isopropyl alcohol.

After you clean your boards and void your warranty, take that 91% alcohol, put about a half-inch in the bottom of a one-gallon glass apple cider jug, swirl it around, and drop in a match. It'll entertain the kids for hours. To do it again you may have to blow into the jug to add some oxygen.

RE: [Elecraft] W1 Software Functions?
Did you download the Windows software? If so the default display shows that you can monitor both the forward power and SWR as moving bars and with numerical readouts in their own windows. That's the default. Then you can start pulling up other data. Clicking REVERSE will change the SWR bar and data window to show reverse power rather than SWR. In the SETTINGS drop-down window you can chose between having the windows display and the LEDs on the W1 display average power or peak power, and you can select Peak-Hold LED ON which does just that: the LED on the W1 representing the highest power reached will stay on. For operating convenience you can adjust the behavior of the range and power LEDs on the W1 to have them decay more quickly or slowly when RF drops or, if you're not interested in the W1 LEDs because you are using your computer, you can turn them off. If you want your settings to be remembered next time you use the W1, don't forget to click on SAVE in the SETTINGS drop down!

Re: [Elecraft] Solvent
You could always go to a Liquor store and get some Everclear, pure spirits. However, cleaning of the Elecraft boards is NOT necessary nor desirable. You never know what the plastics in today's parts will do in the presence of solvents. Use of the cut off acid brushes will work, but only as long as the solvent and brush are clean. They quickly load up with excessive flux and rosin, if there was excessive presence of these in the solder joints.

[Elecraft] K1 Receives as good or better than K2
I have read the 25 reasons commonly found for K2 poor reception, and many other posts. My K2 receives, transmits, and I get good reports. All of the resistance and voltage checks were right on the mark. The alignment was done by the manual, but as I recall there were some times that I did not hear real sharp changes when aligning. It just seems that the K1 is receiving a bit better than the K2. Shouldn't the K2 receive better than the K1? Would realigning with a better source (N-gen vs. by ear) possibly be the cure? Thank you ahead of time for any suggestions that may help me solve what I think? is a problem. Heck, maybe the K1 is just that good and out hears the K2?

So far have not heard from Elecraft support on this. 73, Chuck NI0C - Original Message - From: Jean-François Ménard [EMAIL PROTECTED] To: Chuck Guenther [EMAIL PROTECTED]; elecraft@mailman.qth.net Sent: Wednesday, December 13, 2006 8:16 AM Subject: Re : [Elecraft] KDSP2 questions Just switch ON clock in SECondary K2 menu - Message initial De : Chuck Guenther [EMAIL PROTECTED] À : elecraft@mailman.qth.net Envoyé le : mercredi 13 décembre 2006, 08 h 22 min 38 s Objet : [Elecraft] KDSP2 questions 2.)

This works for me, but is there a better fix for this? The manual also says to let us know if this happens frequently. I have e-mailed Elecraft support regarding this. __ Do You Yahoo!?

RE: [Elecraft] KDSP2 questions
Chuck, If you get the not inst message it means that the KDSP2 is not being recognized. The fact that it is intermittent indicates that there is a bad solder connection somewhere. You might try re-flowing the solder on the KDSP2 board. 73, Don W3FPR -Original Message- I assume you mean the rtc (real-time clock). It is on (or at least starts out that way, with power on).

RE: [Elecraft] K1 Receives as good or better than K2
Steve, Are you perhaps confusing 'hearing louder' with 'hearing better'? The K1 has an extra stage of audio amplification, so signals may appear louder - but listen for the extremely weak signals, you should find the K2 is better in digging out those weak ones - that is the K2's better MDS and Dynamic Range parameters working for you. The K1 is good, but the K2 is even better in weak signal reception. 73, Don W3FPR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Steve Watkins Sent: Wednesday, December 13, 2006 9:02 PM To: elecraft@mailman.qth.net Cc: Watti Subject: [Elecraft] K1 Receives as good or better than K2 I have read the 25 reasons commonly found for K2 poor reception, and many other posts. My K2 receives, transmits, and I get good reports. All of the resistance and voltage checks were right on the mark. The alignment was done by the manual, but as I recall there were some times that I did not hear real sharp changes when aligning. It just seems that the K1 is receiving a bit better than the K2. Shouldn't the K2 receive better than the K1? Would realigning with a better source (N-gen vs. by ear) possibly be the cure? Thank you ahead of time for any suggestions that may help me solve what I think? is a problem. Heck, maybe the K1 is just that good and out hears the K2?

[Elecraft] K2: Hi Cur on 30m
I just noticed I'm getting a Hi Cur message only on 30m. The set up: - K2/100 into dummy load (KAT100 disconnected) - Power set to 100 W - CAL CUR set to 3.50 A - When CAL CUR is 4.10 A, current drawn on 30m levels out at 4.02 A - When I drop to 85 to 90 W, 30m draws just under 3.50 A - All other bands draw less than 3.50 A - I qso on all bands with no apparent problems If anyone has been through this, what do you think - have I possibly zorched my PAs? Should I recalibrate? (It could have even been this way all along I never noticed, since I often have the power level less than 100 W.) Or am I being paranoid over a half amp?

RE: [Elecraft] K2: Hi Cur on 30m
Mike, First, count the number of turns on L4, L5 and L6 in the KPA100 - count the turns that go through the center of the core rather than the outside. An extra turn on these windings would produce the Hi-cur on 30 meters. How old is your KPA100? If the kit was ordered mid-2005, then you may have the inductive resistors at R19 and R20 - that problem usually appears at 20 and 17 meters, but occasionally shows up on 30 meters as well. You can obtain replacement resistors from mailto:[EMAIL PROTECTED] . I don't think you have 'zorched' the PA transistors. If the turns on the KPA00 low pass filter toriods are correct and all the C3x capacitors are correct, you may want to install the KPA100UPKT and see if that brings things under control (that upgrade kit does include new R19 and R20 resistors). 73, Don W3FPR -Original Message- I just noticed I'm getting a Hi Cur message only on 30m.
