Hallicrafters TO Keyer a Fine Addition to My Retro Shack

Some time ago I purchased this 1950’s vintage Hallicrafters Keyer, and it finally arrived from the US. It is quite cool to have a digital device driven by vacuum tubes  as part of my retro shack. Here I am demonstrating it. This was the very first time I attempted to send using it, and it has a completely different feel to my usual electronic keyer. It does not store key presses like electronic keyers, so your timing has to be spot on. Practice is the  key.

A quick adjustment of the keyer. Weighting adjustment requires an analogue ohm meter.
