In a word, NO.
A PAC-RT is a unit designed to extend a mobile radio
to a handheld. Picture a highway patrol officer that is
out writing a ticket - the handheld on his belt talks to
his patrol car and the PAC-RT there is hooked to his
regular mobile radio. Think of a simplex autopatch but
with an underdash or trunk mounted mobile radio in
place of the phone line. It is a crossband* unit with
an output power of 1/10 watt ... some were 1/4 of a
watt, but not many. There is no duplex ability at all.
* crossband: receiving and transmitting on a different band....
The patrol car mobile and the officer's HT are on totally
different bands. The PAC-RTs were built around an RF
package based on a low-end handheld, and models
were available in the 150mhz and 450 bands.
The basic idea of "extending" an existing mobile radio
into a mobile crossband repeater is still in wide use.
For example, here in California our highway patrol
mobiles run on hilltop repeaters with a 42-43mhz
output and a 39mhz input. The officer's handhelds
are on high band.
