[1000mp] ft1000 MP or field low power

[Cecil Acuff]

The wording in my MP manual (100W radio) does mention what you have stated 
below.  It also says that thought the cooling system is designed for 
continuous duty transmission at 100 watts they recommend running it at 50 
watts to avoid the possibility of overheating it.

In commercial gear....100% duty cycle means just that.

I haven't run RTTY in contest yet but would expect to run the radio at 
reduced power probably starting at 50W without worrying about heating it up 
too much.  I think what was meant in the 3 minutes on 3 minutes off was at 
full power.  That's 50% duty cycle by commercial standards....

My FT-1000D (200w radio) manual states 100watts continuous duty.  If more 
power is needed for RTTY it can be run at 200W with 3 minutes or less key 
down and at least 3 minutes of receive to allow cooling.  (that's a more 
honest way of stating it true duty cycle) So I would expect to be able to 
run the "D" at 100w with no issues....so it looks like a 50% rule on the 
power out is a safe place to start.

If you are wanting to know what power level people are calling QRP while 
running a 100 to 200 watt rig that's another question all together....

My definition would probably be 5 watts or less to qualify as 
QRP.....certainly not 100.
