No way.  All the AMPS phones were ordinary FM.  No amplitude component
to offer creative specmanship.  Key the xmitter and the average, peak,
and RMS RF power output are all identical.

See my other rant on the subject.

The 1.2 watt limit was for hand-held and transportable half-duplex
(i.e. PTT) cellular phones, which nobody bothered to build and sell.
It was NOT an FCC imposed limit, which only limits the phones to 7
watts EIRP.  However, I suspect that RF exposure limits, which
appeared at about that time, probably were the prime motivator.
