[Elecraft] KPA100 check result questions

Good morning, I'm still in the process of building my kpa100. After my learning process concerning soldering :-) I stumbled upon some voltages. I'm on page 43 in the manual now and got some numbers a bit off the given values (PS is 14V). D13 154V U4 -27.4V TP1 0V J3+ 0.1V Are these numbers ok?

[Elecraft] K2/100 Underway

Hi all. K2/100 #4703 is well underway as a replacement for an earlier build K2 #29xx which I sold and have regretted ever since - in spite of replacing it with a MP Mk5! This time it will be the Mk5 that gets sold as soon as the K2 is up and running! Thanks for all the interesting reading on

RE: [Elecraft] KPA100 check result questions

Gerhard, The voltage at D13 and U4 are a bit higher than they used to be - they increased when R4 was changed from 100k to 39k, all is well with those two. Your voltage at TP1 is good, but you may want to re-check J3+ (red) - while 0.1 volts may just be some artifact of your meter, the voltage

RE: [Elecraft] K2 BAT

If one keeps the K2 connected to a 14.1 to 14.3 volt power supply that is continuously running, the battery should stay charged. If you prefer a better battery charging system, look into creating a direct battery connection and using a 'smartcharger' - for my implementation, see my webpage

Hello Chris! I have just built the KDSP2 and everything seems to work properly, including the clock and changing the filter frfequencies. However, the red LED remains on... This is certainly peculiar. If the DSP is working, the first thing it does is turns off the LED. This feature is

Hello Christian, The issue, though, is that when I tap the menu button or the display button, not inst will flash for a second before the menu is displayed. All tests checked out after power up, except the keyer, since I don't have a paddle. Let me add that at this point, I am missing one

[Elecraft] KSB2 Capacitors

Hi, I have a KSB2 kit supplied about 11 months ago. The instructions are Revision D. I see there is a Revision E on the website. The only difference appears to be the lettered capacitors CA, CB etc in the xtal filter which have changed in value. Should I obtain caps of the revised value to

[Elecraft] KPA100 voltage measurements AGAIN

Hi there, since my last thread has gone wild ;-) ... here comes a new one. I just checked the PCB again for any visual problems but didn't find any. And then I did the measurements again. I now have -0.1 to -0.15V on J3+ (yes, MINUS). Still zero V at TP1. Any idea how this voltage could get

[Elecraft] 2 k2

David, I've been an SO2R operator for several years with a pair of IC-765s and completely agree with other's SO2R sentiments. I sold those 765s with the idea of replacing them with the much better receiver specs in 2 K2/100s. I just built my first K2 (#4687) and gave it a good work out in the

RE: [Elecraft] KSB2 Capacitors

John, Those capacitor value changes will change the filter bandwidth from the older 2.1 kHz bandwidth to the newer 2.3 kHz width - nothing but the capacitors need be changed. That is the only change (and it is equivalent to the KI6WX filter bandwidth mod). Yes, I do recommend it - unless you

RE: [Elecraft] Help with K2 Q7 collector resistance test

Neal, Try removing the Control board to see if the resistance moves up substantially - if it does, look for the problem on the Control Board or its connectors, oterwise look for the problem on the RF Board. The best advice I can offer is to look at the schematic and find all the points marked
