Title: Radio noises
Post by: Gordonjcp on June 09, 2009, 03:05:40 PM

I'm putting together a wee pack of interesting and odd radio noises, and of course the circuitbenders.co.uk faithful get first crack.

Usual licence applies - samples are CC-BY-SA with the possibility of CC-BY with my permission.

First up we have a French-language shortwave radio station on 9.970MHz.  Because my HF transceiver is SSB-only (no AM) it is very fiddly to tune exactly onto the frequency.  When it's off-tune instead of being all crackly like an AM radio it pitch-shifts the incoming signal.

Enjoy.

nice :)
btw, ive heart that if you connect the antennea's from 2 radios, set to the same station, they go ringmodulate..
never tried it.. wonder wat happen with 3 ór 4 radio's...

No, they won't ring modulate.  You *might* get some odd interference on two FM radios tuned about 11MHz apart if they were very very close together.
