Look at the SBE-33 and SBE-34 ckts. They used them...

The SBE-33 and 34 circuits (plus a rig from QST "transceive with
transistors")
are bidirectional, but only in one direction at a time. The direction
of operation is switched with the ptt circuit. I think he means in
both directions at the same time, as would be used in full duplex
phone circuits.
