Brian, et al.
My experience with small DIP relays and cathode
keying not good. Tried two varieties and both
left me on air with a nice carrier after only a
few QSOs.....the contacts sorta melted together.
My solution was a Western Electric mercury-wetted
relay (like in the TO-1 keyer). You can find these
often at fests...even used one of these on RTTY a
few years ago, coil is only a few ma, can key with
TTL, and plenty fast.
