Having trouble identifying noise?

iaru1

Have you ever had trouble identifying different noises on the Bands? Maybe a usual one which we class as ‘Radar’, Digital Modes such as PSK or RTTY or maybe just something that arrives at short notice and you haven’t heard it before?

Check out a few of these noises on the links listed below. Its likely you will find the answer here;

– Plasma-TV on 3500 kHz (USB)
– Plasma-TV on 3500 kHz (AM)
– Plasma-TV (standby condition) on 3500 kHz
– TV switching power supply on 14000 kHz
– Small LCD-TV on 7000 kHz
– Large LCD-TV on 3515 kHz (USB)
– TFT Computer Monitor on 21377 kHz
– Computer monitor on 18100 kHz
– Broadband (DSL) modem on 21000 kHz

Failing that, click the link below to see a full list of the many soundfiles that should help you identify what you hear;

Charles M0OXO

I was born in the 1960’s and have lived all my life in the Coal Mining Town of Barnsley in South Yorkshire, Northern England. My parents were all from this area of Yorkshire and my father worked in the main Industry of the local Collieries as a face worker. I have been married to my wife Debbie for 35+ years and we have two children and two grandchildren.

I have been licensed for around 20 years after my interest was re-kindled when I retired from my role as a Police Officer within South Yorkshire Police Force. The latter few years were spent as Radio Operator in the Force Operations Control Room at Sheffield, before my career ended.

IOTA chasing is (and always has been) my real passion, as climbing the ladder to reach Honour Roll status was always my main aim. The 1000 Islands Trophy is still out of reach but I am heading in the right direction. I am currently a Board Member of IOTA Ltd and IREF.

In my free time I am a keen Photographer of Wildlife, Aviation, (anything really) but the QSL Manager role is my main passion within Ham Radio.
