[Elecraft] Kdsp2 Problems
Hi, I cannot get the initializing led to flicker on my kdsp2. When I do the voltage checks, I really cannot make sense of it, versus the schematic. I have double checked that the right parts are installed in the proper orientation, re-checked for bridges, etc. I have checked that none of the control board components are rubbing against it and I am currently blind to the problem. The voltages on U1 are not right. Pin 5 should be 0 and its 4.96v Pin 14 should be 5 and its 0v Pins 15-19 should be 0 and they are all 4.96v I saw a post from January with these same indications but never saw an answer.

[Elecraft] KPA100 audio problem
I assembled my kpa100 during the week, what a nice experience! The functional operation of it is fine, aligned well, tx audio is good, temp, etc. all fine. The problem I am experiencing is with the audio. If I plug the audio cable only into the k2, audio is as good as the original. But if I plug either the 12v line or the rf line, it sounds very tinny and distorted. When I connected the speaker plug from the orginal k2 top and then plugged in the 12v and rf line from the kpa100, no audio distortion. I assumed I might have wired my speaker backwards, but even with both connections free from the kpa100 speaker, it distorts whenever I plug in the 12v and/or rf cable. So its something on the kpa board itself. The problem is there really is not much in terms of audio circuitry on the KPA.

Re: [Elecraft] Looking for some help from an Elcraft builder in Massachusetts area.
Being one of those clogging the reflector recently with cries of help, let me put it in context. In building the base kit I experienced only 3 problems: I had a poor solder joint that kept me from getting the right AGC voltage but the troubleshooting guide led me to it almost immediately. The second problem was that I was getting less resistance than indicated when doing the RF board. It turned out that I had a solder connection that touched the case of one of the transistors and it 'shorted' that path out. Took me a while to find it but it was just a small mistake, anyone would find it given a little time. The third problem was that I mis-identified two diodes and inadvertantly swapped them. Doing a careful inventory at the beginning would have prevented that from happening. The other thing I have asked for help on turned out to be me not following the instructions properly, forgetting to take out a capacitor when installing the SSB board. So, 1 bad solder joint, 1 shorted solder joint, 1 parts misidentification and 1 not following instructions. Each of them was not hard to find and with the experts on the list, they can almost tell you what you've done! Do not worry about building the kit, its really easy and turns out that its so much fun you want to keep building more! 73 de k3nc On Feb 22, 2005, at 10:18 PM, [EMAIL PROTECTED] wrote: Hello to everyone on the Elecraft Reflector.

[Elecraft] KSB2 Problem
Hi all, I am trying to install the KSBS2 into my K2. Problem symptoms are that I get the Hi Current warning, plus I get no variance on my separate receiver when trying the fine balancing. The rest of the alignment went okay, SSBA on BAL gave me good nulls with tweaking R1 both on USB and LSB (I just cannot hear any null with the receiver. I get a very strong carrier (S9+) on my separate receiver with SSBA at 3. Doing the voltage checks on rx, everything looks okay with the exception of: U1, pin 22 - 5.6v instead of 0.2 U2, pin 5 - 5.95v instead of 0.6 U3, pin 6 - 1.4v instead of 0 U4, pin 3 - 5.95 instead of 0.6 Since I get the hi cur warning I have not tried any tx voltage measurements. I looked at the archives and saw some people put RF board Q2 in backwards but the 'silver' side is facing the front of the rig. Any ideas?

Re: [Elecraft] KSB2 problem status: befuddled
Hi all, Thanks for giving some ideas! I checked the resistors on the bottom of the ssb board, they are all correct. I must say that trying to identify parts on the top of the board is a real challenge, its so stuffed that its almost impossible! Don, I redid the output amperage at 10 watts: 80 - 2.68 40 - 2.72 30 - 2.28 20 - 1.96 17 - 2.42 15 - 2.50 12 - 2.24 10 - 2.16 At 10 watts on 40, the voltage on rx is 13.5 on tx its 12.9. The group is right, I did not notice the power output on lower than 17m (which is 15 watts). On 15 through 10, highest output is 13.3 watts. Do I still need to investigate the 40m current usage? Do I need to replace the 3 resistors and jumper that I pulled out to eliminate the noise blanker module from the mix of things to investigate? I should have done one module and waited to know it worked before doing a second one! Neal On Feb 21, 2005, at 5:37 PM, W3FPR - Don Wilhelm wrote: Neal, There may be nothing wrong with 40 meters after all - I had missed the point that you were setting the Power control to absolute max. What is your power supply voltage? 13.8 volts is typical (13.6 on the display), and lower power supply voltages will result in increased current draw. What is the voltage when you are seeing a current of 3 amps or greater? I don't have a straightforward answer here. Can it be that your Carrier Balance is not correctly set and you are really generating more RF drive with SSB than with CW? It is not really a fair comparison to compare current draw from band to band with the Power control set all the way clockwise. Set it to 10 watts and check the current drawn for each band and both CW and SSB modes. Actually SSB mode should draw little current without audio if the carrier is balanced because there should be little or no RF output. 73, Don W3FPR -Original Message- Hi Don and all, I have spent the afternoon looking for where I could have made a mistake on the 40m LPF circuit. I didn't find any obvious ones, the toroids came from 'The guy de Toroids' but I counted them all anyway, and they are (luckily!) correct. Same for capacitors. Did the run of voltage checks and didn't notice anything really wrong. On cw, cranking the output knob to the max, the display readings for current are 80 3.22 40 3.36 30 2.84 20 2.38 17 3.08 15 2.84 12 2.62 10 2.42 Output reads over 15 watts in all cases, usually abt 15.2. This reads pretty much the same with or without the SSB module installed. I take it from your comments that the fact that 40m is the highest cw reading, its indicative of something wrong. Looked at LPF and BPF areas. What should I expect on the amp readings, 2.35 on 40 and a gradual increase as I go towards 10m? I could reinstall the resistors and jumper and take out the noise blanker module as thats something put in yesterday, I take it that I need to do that if I want to test without it? I have boosted cal cur to 4.0 and still can get hi cur signal with output fully counterclockwise on both usb and lsb. I have been very happy working cw all week as it is (set the cal cur to 3.5 and it hasn't tripped yet).

Cranking the rf power all the way clockwise shows 15 watts on k2 and hi pwr message (cal curr set to 3.25) and external wattmeter shows 19 watts. I examined T2 and had it too tight to the RF board so have re-installed with gap. Part 2 alignment works perfectly, part 3 resistance checks okay.

Re: [Elecraft] Proper resistance for Q7 collector
Well, just in case anyone searching the archives for hints on a similar situation, I had a solder bridge on the top of the RF board between the case of Q5 and the lead from R44 that fed from the bottom, just impossible to see without magnification, etc. Probably no one will make the same mistake but just in case, thats what caused this one.

The only real way to tell is to use your DMM on another K2 and compare (or find someone else using the same DMM). With my K2, I read about 600 ohms when I first apply the test leads and climbs to about 1000 ohms after a time - then reversing the probes, the reading starts out at 600 ohms again and climbs to about 3K ohms after a time. If you remove the control board, you should see a more steady reading - in my case about 1k with the probes in one direction and about 3K in the other. With the control board installed, the readings vary as above largely due to C28 charging through R16.

Hi all, I have been through the archives so I know this has been asked and answered a few times but I still am not making much progress on this. The problem is that my resistance test for Q7 collecter is not correct. With the common probe on ground and the positive probe of my DVM measuring resistance, its abt 280 ohms. If I reverse the leads, its around 408 ohms. All other measurements seem okay. I have the heat sinks unscrewed and point in the air, not touching anything. I have remove T4 (as it looked like it could be a source of problems) and the measurements are not changing. I have magnifying glass inspected things, blown the top and bottom of rf board with compressed air, etc with no real movement. Prior to the alignment in part two, the resistance reading on the 12v line was 788. I did not realize that the polarity of the DVMs could change the reading so I have no idea if I had the common probe grounded or vice versa. The alignment and test of the part 2 instructions went as expected. Any ideas to unblock me?
