Attention drawn by a post to the SKCC email list to video on the GHD keys site illustrating the ‘European’ style of keying, demonstrated appropriately enough in this video by a Japanese operator. On this page it’s described as the ‘Reaction Method’.
Also saw an interesting exchange of comments on the SKCC list about this style.
Also found the GHD catalogue an eye-opener. Some very sophisticated keys and paddles there. Again these keys are also available from Morse Express.
