[Elecraft] K3: USB Adapter cooked

[Lee Buller]

I just want to make an observation....about the USB Adapter.

This weekend, I was running about 500 watts output to my Inverted-L on 160 meters.  Time after time, N1MM Logger would loose connection to the K3.  I did attribute this to RF.  I stopped and made sure everything was grounded properly, I placed some chokes on the USB Adapter line, did a reboot of the rig and the computer.

Well, finally, the adapter quit working.  Nada.  I rummaged around in the garage and found a serial cable and connected it to the computer and was back in business.  The N1MM Logger program and the K3 performed flawlessly after that.

Now, I know that there are some issues in my shack concerning my Inverted-L feed.  The feed point is less that 15 feet from the shack/rig/tuner/amp.  All were grounded to a single point.  Still, the USB adapter cooked and I attribute this to high amounts of RF in the shack.  And, since I am not going have any more children...it seems that I just lost the USB adapter.

This only happened on 160 meters.

Any comments?

In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?
