[net.columbia] TRDS-1 Impact?

dad@u1100s.UUCP (08/18/83)

Does anyone know whether having the single TDRS satellite (i.e. TDRS-1)
functioning during STS-8 will significantly increase the percentage of
time that there will be shuttle to ground communications?
Or do we have to wait until there is a full set of TRDS satellites before
they really begin to have an impact?
