Little people invading?
Seen a lot of radio stuff with 433Mhz written on it recently. I have a clock with temperature display and a remote transducer with the said mark. So I got my uv-3r out and had a scan around and found it’s burp on 433.920Mhz but if I go up 5khz and open squelch I get an almost constant stream of chirps and burps. Further investigation found http://en.wikipedia.org/wiki/LPD433 , http://en.wikipedia.org/wiki/Low-power_communication_device and http://en.wikipedia.org/wiki/Remote_keyless_system. Low and behold my car keys give out a buzz near there.
As well as that we have http://ukhas.org.uk/general:beginners_guide_to_high_altitude_ballooning doing some cool stuff on 434.075Mhz, http://ukhas.org.uk/guides:tracking_guide. They have their own protocol http://ukhas.org.uk/communication:protocol looks simpler than APRS and works ok, this is the sort of thing we could all be doing if not for http://licensing.ofcom.org.uk/binaries/spectrum/amateur-radio/guidance-for-licensees/samplelicence07.pdf section 9(3)
9(3) Without prejudice to Clause 1 of this Licence, the Licensee shall not establish or use the Radio Equipment in any Aircraft or other Airborne Vehicle.
We could make use of this simpler protocol on HF? For direction finding as that is the only way we can beacon other than 144.800Mhz without NOV (notice of variation)
I also noticed we were turfed out of parts of 70cm for the Olympics. 70cm is a nice big band in a prime part of the spectrum and we have it on a secondary basis, if we don’t use it others have the right to do so.
If you a Foundation Licence see table A in the licence, it’s your highest and biggest apart from 10Ghz. So cherish it.
