Bull Dog Iambic Paddle http://www.amateurradioproducts.com
I originally purchased this for my Rockmite QRP rig and ended up using it for my KX3 when the KX3 paddles failed. Well after a month of use the solder joint on the back of one of the paddles (coat button) let go and I had to resolder it.
The fix was pretty simple and I was able to continue to use it till the 3.5mm stereo input plug starting giving me problems. I would be in the middle of a QSO and it would stop working all together. Luckily for me, my KX3 paddles were back from repair and I was able to go back to using them. Such CW paddle drama…
