dear yang
your keys will be posted tomorrow morning (8th march)
the adjustable contact, locking wheel and the spring tensioner nut have been gold plated, so do not use metal polish on these when cleaning the "big brother" key.
the "baby" key is fully adjustable. to adjust the contact, unscrew the knob and slacken the finger guard. there is a screw driver slot in the adjustable contact.
i am sorry that the g4zpy label is so large. i appear to have run out of the tiny ones that i normally use on that key.
a "baby" key was used in a qso from france to australia, and a lady in england passed her 12 wpm morse test on one.
we hope that you get many hours of pleasure using your keys.
best regards,
gordon. g4zpy
