[Amps] Emergency communication

[Roger (K8RI)]

Without a lot of compression and clipping the duty cycle for SSB is only 
20%. Given 100W out at 60% efficiency, we are looking at roughly 167W 
input at the 20% duty cycle or roughly 34 watts. Depending on the 
exciter we are looking at less than 100 watts total power consumption 
for a 100W SSB signal output.  Often, much less power consumption.  
Unfortunately this is not true for the new, top end rigs with all the 
bells an whistles.
