[Amps] Novice heater choke question

It would really be nice if the guys crabbing about rules violations 
actually knew what the rules were!

The FCC limits power on the 137 kHz band to 1 watt (that is a "ONE") 
EIRP. I believe that is an international rule as well.

In point of fact, since the typical antenna system on 137 kHz has a gain 
of -25 to-40 dBi (note the minus sign!!!), a 1 KW out amplifier is quite 
reasonable!

BTW, here in the USA, those of us with experimental licenses can run as 
much power we ask for on the grant application! At the moment, even 
though the 137 and 475 kHz bands have been allocated for Amatuer use, we 
do NOT have permission to use them yet! Of course those of us who have 
an experimental grant are actively using those bands right now and have 
been for quite some time.
