[aprssig] 9600 baud TX equalization

I was just reading over the original docs on the G3RUH modem yesterday, and
I noticed that it makes a big deal of transmit equalization.  Several
different waveforms were provided to compensate for frequency and phase
response in the transmitter.  In reading the manual for the KPC-9612+, I
only see an option for RX equalization.  What's the deal?  Are modern radios
consistent enough in their frequency and phase response to not require
adjustment on the TX side?
