This picture shows my Bencher RJ1 straight key, and BY1 paddle. On the 756Pro, the straight key can plug into the rear panel, and the paddle can go into the front panel. Both keys are available at the same time, which is convenient for going between the fixed speed of the built-in keyer, and the variable speed straight key.
Also shown is my current headset, a headphone/mic combination made by Plantronics. The HS1, it is designed for computer use, but works very well with the 756Pro. It is also inexpensive, especially when compared to amateur radio headsets. Details on the microphone interface to the 756Pro can be found on another page.
