HELP!!!!!!!  With Field Day coming up, our club is likely to need
to key some old grid-block-keyed radios (I know, get into the right
decade!).  There was a circuit going around that used two transistors
and would key either solid-state or the older grid block transmitters,
but I can't find it anymore.  If anyone has it handy, could you
get in touch with me?  Tnx.
