Two stroke diesel engine on a narrow boat on the river weaver cheshire - running at normal cruising speed. Audio track separated from a video. Camera was just in front of cabin - filming for most of the time towards the bow. The sound was captured when the camera was turned to film the two boaters at the helm.
This sound is recorded directly from one of my original 1938 98cc light motorbikes. This time is a express (manufaturer) sl 102 (type). The noise you hear is all specific. It is the fuel cock on selection, the flooding of the carburettor, suction of the engine, two tries to bring the engine to live with clutch action inbetween. Running on idle and two short openings of the throttle. Engine is shut off by using the decompression lever which is typical for this period of time and two stroke engines. .
Sound of a pickup truck. Keys jingle, door shuts, starter click, engine turns over and sits idle, tires roll over gravel slowly, then truck drives away. Normalization applied.
Qrm listened in am mode on 80 m band in my qth jn79ek. If i use cw mode listening and narrow filter, the qrm is mostly worse. Strength: peaks s9+40 db. Sometimes any traffic impossible. From -41st sec. Of record is possible to heard my tuning around frequency.
I recorded stop and go traffic on coldwater canyon one morning on my way to work. Nice variation of traffic that's moving and traffic that's just stopped and idling. Could be used for freeway traffic jams, etc. Recorded with: sound devices 702t, beyer dynamic mc930 mics.
I did a ferry crossing over the little river mulde (was on a bike trip berlin-buscha ). The ferry is for pedastrians and bicycles only (some times a horse), it is without an engine, just power of muscles.
