Most of us will have experienced the frustration of some or another sort of noise on the bands.

Can we recognize by what we hear, what the possible source of this noise can be?

Can we find any information and support about what torments us most?

UKQRM website has a good collection of information plus identified sources AND audio recordings of noise samples. Website:

http://www.mikeandsniffy.co.uk/UKQRM/ (eye opener the "Sound Database"
eg Mains powered (12vdc)ultrasonic cat deterrent Frequency range 10-30 Mhz !

For more QRM samples,please navigate to YouTube, then enter UKQRM or go to:

Let's stand up to "noise-bugs" by being informed about their..."habitats" ;)
