KPA100 check result questions
Locked
 
|
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? Especially the last two? Another thing. The fan at this stage is a bit out of control. Calibrating tPA helps, but the K2 seems to not remember this setting. Also strange is that while setting tPA a relay can be heard switching. But maybe this is normal at this point in the process? Kind regards and keep on building... Gerhard DH3FAW ___________________________________________________________ Gesendet von Yahoo!

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 should really be zero. I don't have an immediate answer on your fan situation, but it likely won't hurt anything, so finish everything and see what happens with it. Yes, CAL tPA should be remembered. 73, Don W3FPR > -----Original Message----- > > I'm still in the process of building my kpa100.

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 www.qsl.net/w3fpr 73, Don W3FPR > -----Original Message----- > > > I was wondering how does everyone keep there elecraft battery in the k2 > charged up and ready to go? > > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I could not remember if the battery was charged through the 12 volt supply

Hello Dave,
> I was wondering how does everyone keep there elecraft battery in the k2 > charged up and ready to go? yes, I do it with an accumulator charger (output 13.8 volts). But I have modified my K2 #01118 a little bit. Please see at www.dk3red.homepage.t-online.de/en/s6.htm#trx6 and read the additional suggestion by Bart PA3GYU in my guestbook www.dk3red.homepage.t-online.de/en/s13.htm dated 25th August 2004. There are no problems with the battery since my K2 is on air. -- 72/73 de Ingo, DK3RED Don't forget: the fun is the power!
