Belo Review, Francisco. Linda chave. Deve ser macia e precisa. O micrômetro é cereja do bolo. Vou compartilhar nos grupos de CW que participo. FB QSD 73 de Edu PY2WQ.
What is the reason for putting a piece of padding under the key? The lever moves up and down, not from side to side, AND the key is very heavy, it won't be sliding, jumping,... The padding just flushed the whole PRECISION down the drain, seriously -- it WILL affect the quality of your CW (it's like putting the key on a pillow)). This wonderful key should be sitting on a wooden desk AS IS (and that's when it will work/look its best). 73!
