[Elecraft] Kdsp2 Problem - Initial Checkout No Go

[lbailey at aep.com]

Pete....Looks like Easter weekend is pretty slow for getting help with 
your problem.  Guess the tekkies are out of pocket.  Unfortunately, I have 
not gone down the DSP road yet, so I'm not much help.  In fact, I ordered 
the DSP accessory & the A to B upgrade for my K2/100 (#1411) on Friday.

Looks like you've provided some good trouble-shooting information.  The 
wrong voltages on the U-1 must be indicating a problem somewhere.

I had a problem with one of my options & I contacted Elecraft Tech help & 
they sent me a replacement IC since the problem sounded like a b/o IC. 
Sure enough that was the problem.

Another way to ck for bad solder joints would be to use a digital camera & 
shoot some shots that you could print out or just look at on computer 
screen. 

Good luck, I'll be watching to see what the problem is.

Hi, 
    I hope someone can help me out with my KDSP2. On page 18 during 
initial 
checkout of unit and at the "rtc " display, I am unable to turn it on. 
That is 
, EDIT followed by BAND doesn't turn unit on. On power up of K2, the LED 
does 
come on briefly and turns off. AFIL held shows "not installed". I went to 
trouble shoot section in manual and did everything under error message ( 
removed U1, checked for bent pins, unwanted solder bridges, parts 
installed 
properly and in correct placement, and voltages on U1. Turned power on and 
off 
with no change. I did have a KAF installed before the DSP2 and it worked 
very 
well with no problems.
