Hams like myself are at all times seeking to play with expertise, particularly because it applies to our pastime of newbie radio. Whether or not it’s the latest, prime of the road transceiver or a DIY dummy load, we’re – and this Capacitive Contact CW Key is a neat design! With a small touch-sensitive circuit powered by a battery, it may possibly management any customary CW transceiver. From the look of the design, it may be used each as a straight key or as a paddle, which is a pleasant characteristic.
Why use one thing like this within the first place? Effectively, conventional keys are mechanical, and require upkeep and adjustment – to not point out they’re a bit noisy! This design is totally silent (apart from the sound of your dits and dahs) and can final for a very long time. The one upkeep it would want is the very occasional cleansing of the contact pads, although even that’s fairly unlikely except they get significantly soiled.
The one draw back is that it does require a CR2032. I’d think about that battery life is fairly good, and you’ll after all take away the battery when not in use, however a mechanical key doesn’t want any energy in any respect, and so every have their professionals. That is the type of key that will be very helpful on discipline day, or when in a quiet room with others – the silence may very well be an enormous plus! Simply ensure you don’t name it a silent key otherwise you’ll get some unusual seems to be. 73 and good DX!
