Don et al,

Building your interface today to tinker with this weekend, and bought
the little project box and all.  My question, that I want to make
certain before I burn something up is, the connection to the db9 pin 5,
which is ground.  Is that wire also connected to the shield of the RCA
jack (ground) to the FSK jack on the back of the radio?  IE: db9 pin 7
to base, db9 pin 5 to emitter and shield of fsk jack, and collector of
transistor to center of rca jack for positive on fsk keyer?  Is this
correct, or do i leave the shield floating and pickup ground through the
radio?=20

Just want to make sure before I burn something up.
