Do you have the DB9 plug that connects to the back of the KIO2 restricted
to pins 2,3, 5 ONLY? See page 21 in the KIO2 manual. If you have hooked up
a full RS232 to the KIO2 DB9 there is no telling what has gone wrong, you
can cause all kinds of problems.

I don't recall there ever being a mod for line out level. You might be

In your case, in addition to adjusting CONFIG:LIN OUT, be sure to check your

The K3 has plenty of output for JT65-HF if your sound card is set-up
properly. My K3 never leaves the default Line Out = 10. My sound card

divider on the input) is at 1:00 (60%).

No signals on one band usually means that you have the RX antenna
selected - a quick check can be made by putting the antenna on the RX
Antenna jack. If it is set on, the menu for RANT is what you are
looking for.
The ANT1/2 selection is also per-band, so check that as well.

If it has the KPA100 installed, the cable (if built as instructed) has a
20 amp in-line fuse.
The QRP K2 has an internal 5 amp resettable fuse, so it will protect itself.
What you do need to protect just in case of accidents is the power cable
itself. I would suggest a 10 amp fuse.
73,
That Smartcharger article is on my website www.w3fpr.com.
Steve,
Looking at the end of your post, I see that you currently have a 1 amp
fuse which is too small.
Your 2.4 amp power supply is OK if you are limiting power to 5 watts,
but if you want to run 10 to 12 watts (how about SSB on peaks)
