But traditionally we've always transmitted to receive only devices.
In the early days, you had a general coverage receiverand  a seperate crystal controlled transmitter with, in the days 
of battery supplies, nothing connecting the two.
They are definately both one way only devices.

And where in the rules does it say that the reply to a transmission has to be instant. It rarely was using the AX25 
packet network. Whilst with packet or TOR there is usually an ACK packet, that's for housekeeping and not communication 
between the stations.
A reply tomorrow to a message today is valid.
