That's some fearsome beastie!!

Some years ago, one of my hobbies (vices?!) was amateur radio. One of my activities within that hobby was to be antenna mast rigger for a group that took part in Field Days. You set up the station(s) at some field location starting on Saturday morning, start operating at 13:00 and work through until 13:00 on the Sunday. In the case of our group, the stations were powered from a single cylinder diesel generator.
Although the field location was away from home, there were usually residential houses nearby and the noise from the diesel was a problem in the stilly watches of the night when other background noise was low.
The low frequency noise from the diesel is difficult to screen or suppress and I often wondered if we should have tried to obtain a gas turbine-powered generator, for example an ex-aircraft APU, on the basis that the higher frequency noise would be easier to muffle.
I'm out of that hobby now but I'd be interested to hear members' comments and experiences.
Best regards,
