[Milsurplus] PU-18/A ???

[jcoward5452 at aol.com]

Geeez! I thought you guys  loved all the rotating electrical machine 
noise! My DY-17 must sound like a pussy cat compared to a "sceaming 
Mimi"! AN/ARC-5 dynamotors are down in the noise floor!

Unfortunately, it's a function of the centrifugal blower in the end of 
the inverter. It resembles the business end of a siren. Very efficient 
at moving air, but also efficient at creating an amazing level of 
acoustic irritation....
