back to article That's the frequency, Kenneth

Last November we kicked off a competition to identify the radio frequencies used by various bits of kit around the modern home, and now we have a winner, and some explanatory notes. No one managed a clean sheet – of the 18 questions the maximum score was 16 and only a handful of readers managed that. But from the random hat we …

    Ho hum

    Can't really recall the original article or maybe I just missed it. Oh well.

    Too many frequencies for GPS? Er, no, not really. Though spread out a bit, there are what, five ("single") frequencies defined, says wikipedia, but one isn't used, one is for the nuclear detection satellite payload so not something location receivers care about, one has only been used since 2010 and isn't applicable to this consumerist use anyway, one is military though newer high-precision civilian receivers might use it in the next half decade or so, and well that leaves only one, the civilian GPS signal. A simple gpsmouse thingy will only listen to L1, 1575.42MHz.

    Thumb Up


    Though I'm more of a software guy, your articles are kindling an urge to tinker with physical stuff - could be dangerous!

    Keyfobs are usually 433.920

    But my scanner only goes in 5MHz increments.

    The frequency is usually marked on the board.

    I have fixed enough Vauxhall ones to notice this.
