002: Electric keyers


The left is one for the single lever paddle. The memory has installed but squeeze key operation is impossible (made in 1978). The center is accu-keyer. I think it is a modern standard (making was in 1980). I imported the Bencher paddle from the US, and I have used them in a pair for a long term in my shack. The palm sized small keyer on the right is use of JJ1GRK's pick-IC. A slight of delay sequence is programmed in this IC, and the full break-in operation of home brew transceiver is done so nicely(making in in 2006 using the IC). It is a function only to make the morse code of 3:1 ratio. However, why do we feel the attachment in electric keyers?
