Typically, you can only be key down for about 10 seconds at 1.5 KW before the amp reverts to 1.0 KW. However, there is a mod which, IIRC, only requires cutting a couple of wires, that extends that time to around 15 seconds. The mod is available from Expert Rome, but I can post a copy on the Files section of the reflector if anyone is interested.

I'm thinking of getting an SPE 2K-FA amplifier and I have a question

about duty cycle at full power.



I understand it will run full 1500 watts on SSB and CW, but not so on

RTTY, at least not brick on the key mode. After a certain period of

operation it will cut back to a lower power level.



My question is how long will it run at 1500 watts carrier before

cutting back?



All comments welcome.
