[Elecraft] New K3 KIO3 Line In/Out problem

[Neoklis Kyriazis]

Hi all, and my thanks for the replies.

I have carried out some extra tests and here is what I have:

I have tried plugging a Logitech VOIP headphone in LINE OUT but can hear nothing.

I have connected my amplified speakers in LINE OUT but I only got some hum.


Switching CONFIG LIN OUT between NOR and =PHONES makes no difference.

When I select CONFIG SPKR+PH NO, the speaker goes silent after a second or so
and what little I get on the waterfall stops. It seems to me that there is no output
at all from LINE OUT and somehow the AF from the speaker is finding its way into
the cable from LINE OUT to MIC IN of the computer. (By the way, with no 
headphones or speakers plugged in anywhere, shouldn't I have sound from the
 K3 speaker even with CONFIG SPKR+PH NO ?).

Finally, I tested the software side by plugging my 137 MHz APT/NOAA satellite
receiver into the computer sound card in place of the K3 and it worked (got some
nice pics of the Wx here -:) ). The cables I use for the K3 have no attenuators
built in.

I think I have a hardware fault here only on Line In/Out, as all else works on the
KIO3, including the RS232 connector (got the K3util to work out of the box in
Puppy Linux). What could help me a lot is if someone could verify for me that
a VOIP headphone plugged in Line Out produces audible signal, and under what
MENU/CONFIG and K3 settings it does so. I think the headphones would be the 
best way to test for output on Line Out.

My thanks is advance!
