[Elecraft] PR6-10 Poser, Cont'd

[Don Wilhelm]

Ed,

You may have too many variables to determine what is causing the problem.
Try a few things first to isolate where it is failing.
First connect a BNC jumper between RX ANT OUT and RX ANT IN.
Does the K3 hear a signal at the same strength with RX ANT set on as it 
does with it set off?  It should.  If not, there is a problem with the 
K3 RX ANT, contact support.

Then connect the PR6-10 to the RX ANT jacks on the K3 and connect it for 
power at all times (no selection from pin 11 - install jumper P2 in 
PR6-10) - when you select RX ANT, the signal strength should increase.  
If it does not, you may have a faulty PR6-10, contact support.

Lastly, remove jumper P2 from the PR6-10 and connect using ACC pin 11 - 
connect only the PR6-10 to the ACC connector.  Does it work as 
expected?  If not, check the menu settings for DIGIOUT1.  Should the 
menu settings be correct and it still does not work, measure the voltage 
on the white wire with the preamp selected and not selected.  It should 
be zero when selected and greater than 3 volts when the preamp is not 
selected.

If all the above work as expected, start putting the rest of the cabling 
in place - one cable at a time.  Stop if the preamp stops working 
because you just installed the cable that makes it fail.
