Yep.  Transmitter power.  So antenna gain can be whatever you can get.  Same on 
our other bands.  We can run legal limit with an amp, but we can get more gain 
by using a beam.  There is a difference between ERP and PEP.  The ERP is 
EFFECTIVE radiated power.  100 watts into a no gain antenna is an ERP of 100 
watts.  A 3 db gain antenna gives you an ERP of 200 watts into a no gain 
antenna.  PEP is the peak power out of the transmitter.  That's why qrp ops put 
a lot of effort into antennas, to get a stronger signal without having to 
increase transmitter power.

This is an interesting question.
On the ARRL Page it states,

      30 Meters

Maximum power, 200 watts PEP. Amateurs must avoid interference to the fixed
service outside the US.

Now is that Input Power? Output Power, or ERP Power?
