[GreenKeys] More Transceiver stuff...

[wa2hwj at att.net]

Telesignal made a lot of landline telegraph mux equipment. Those cards
were probably from a frequency division multiplex system. 
I've got a rack full of Frederick Electronics FDM cards that do the same
thing. AP and UPI used to use these systems as well as the military.
