[Amps] The old PEP question.

[Alek Petkovic]

That's dead right. Just tried it with my pair of 3-500Z's, on 14 MHz, 
into a dummy load.

Reading on LP-100A is 1320 Watts sending dits at 30wpm

Plate volts (unloaded) 3200V
Plate current (key down) 650mA

Result: 1290 Watts PEP

Conclusion: Its as close as spittin'.

Key down power is 1180 Watts

Working back to Cam's original question, I reckon he might expect 
1450 Watts PEP plus or minus a few.

73, Alek.
