Hi Thomas.

I thought I would pass along this idea for your readers.

I was using my KX2 on PSK31(and cw!) this weekend at the lake QTH. I felt the rig getting warm. I remembered that my wife bought several of these battery powered personal fans (Cold Sky) in the attached pics. She bought them from Amazon for less than $15 each including a charging stand [QRPer.com affiliate link].

It took me a few minutes to realize that the fan “head” will pivot which makes it a perfect cooling device for the rig.

I often though about purchasing after-market heat sinks but none are needed with this little device. It has 4 or 5 fan speeds and it really moves air and cools my KX2. With headphones, I could barely hear the fan.

I really enjoy your videos and website. I hope this helps you and others looking for a cheap way to cool the rig.
