heads up, something is up, UK be restricting ham radio use

yep, i was just scanning thru ham radio frequencies as told in this freshly uploaded audio recording of an arrl news broadcast Transmitted over the 2 meter amateur radio band on 145.41 Mhz.

these band are supposed to be for amateur radio, a citizens band, not for military or olympics security communications. why would the uk do this? i think there is something coming that UK doesnt want hams interfering with

piggy radio, rofl, your good

ham radio (or piggy radio xD) is a higher class 2-way radio service that requires a license for legal use, it is a citizens band radio though

en.wikipedia.org...

all it says is that usage in the 70cm band will be limited, to specific frequencies, as it MAY interfere with the radios used by the Olympic administrators. So, it is only limited to the areas where the Olympics will be held. It is much the same as when you attend an air show, and cannot bring your air-band receiver with, as it *might* interfere with the normal communications on the airport (at least in certain countries it is not allowed). After checking out my radio-scanners LO leakage from its antenna, I must agree. (My one scanner's LO leaks at a -40dBm level from the antenna), more than enough to jam sensitive radios.

edit on 28-4-2012 by radiotracker350 because: (no reason given)

is it easy to do prank calls on it lol hehehheeheehhehehe :3

I'm sure they'll be using that band width in that area for security reasons.

Did anyone else hear morse code during that transmission?

lol, nah, its alot more formal then 11 meter c/d class cb radio. if you tried that, you'd very likely get reported to the fcc by another operator on that frequency Ham ops can be very touchy sometimes

Well I'm assuming you listened to the guy's audio report.

They're going to use those wavebands for radio communications between Olympic venues in London, the River Thames estuary & the south coast of England. That's for Olympic staff, emergency/medical teams, civil aviation, the Coastguards and the police/security. Extra bandwidth is also required for wifi cameras.

They need all the bandwidth available ... it's a huge event ... so they're asking radio hams to stay off those frequencies for the duration of the games.

Once the games are over, that part of the radio spectrum goes back to the hams/porky piggies.

That's the official explanation. So unless the OP knows something different .........

yes, but technically, they shouldnt be using those wavebands, its for non commercial use. not for police, not for taxis, it is supposed to be a private citizens band.

Amateur Radio - Spectrum Use During the Period of the 2012 Games (28th June 2012 to 23rd September 2012)

Ofcom has identified a need to have short term access to certain segments within bands to which Radio Amateurs have secondary access. Ofcom has been working with the Radio Society of Great Britain to ensure that Games requirements can be met in some of these shared bands, while maintaining enough spectrum for Amateurs to continue to use.

There are segments within several Amateur bands which Ofcom plans to assign to support the 2012 Games and their preparation; some use will also continue for a short time after the Games to support decommissioning of venues. This use will be in geographically limited areas between 28th June 2012 and 23rd September 2012. The frequencies affected are segments of the 70cm band, and 2.390 - 2.400 GHz and 3.41 3.44 GHz.

• We do not require use of the whole of the 70cm band but we request that the following segments are kept free of Amateur signals in the areas identified in Annex A: 431 - 432 MHz, 432 - 433 MHz paired with 436.25 - 437.25 MHz and 438 - 439 MHz.
  
  The microwave frequencies of 2.390 - 2.400 GHz and 3.41 3.44 GHz will only be used for the Games in the geographic areas identified in Annex B.
  
  
  Annex C gives details of some other changes and restrictions that will apply to repeaters and RAYNET use.
  

Full details at link.
*OFCOM - Independent regulator and competition authority for the UK communications industries.

The're saying though that its at the request of the Olympics Committee so as to not interfere in "Games Applications"

If you bothered to check the 70cm band plan for the UK you would have seen:

Note 10: May be used for Emergency Communications and Community Events

LICENCE NOTES: Amateur Service: Secondary User. Amateur Satellite Service: 435-438MHz: Secondary User Exclusion: 431-432MHz not available within 100km radius of Charing Cross, London.

simply station identification

This will become a story if, after the Olympics, they 'forget' to turn this band back over to public use. We've seen it with the commons everywhere, be they parks, school fields, natural resources, even labour. They get hold of something under some noble auspices, then ownership mysteriously drifts away and we must pay for what once was ours.

I'll be watching that frequency, post-olympics, and passing judgement then.

disinformation

only true thing is that ham radio ops do often help in emergencies, but it is not for for government control.
private communications, not world olympics security

Ah, Spoor, you beat me to it..LOL I love it when people hear morse and "assume" that it's a sign of some governmental skullduggery!

Equating the 70cm ham band to "citizens band" is rather like comparing a Chopin nocturne to "Chopsticks". especially when you consider that the 11 meter (27MHz) ham band was confiscated by the FCC in order to create the "citizens band" - and some of us have never forgiven them for it!

The up-side to all of this would seem to be that the Brits have apparently decided that it was cheaper to buy up a bunch of 70cm walkie-talkies for use by the olympics rather than the more expensive walkies that the security services normally use. Watch for a lot of "gently used" ham 70cm FM walkies to show up on eBay after the olympics. Great opportunity to pick up some "bugout" radios.....

Just like the UK Government said that "street cameras in London will *only* be in place during the coronation of Queen Elizabeth, and only in areas of the procession, and then removed" That was 1953.

TPTB are restricting everything.

BTW, OP, if you get in contact or know PA3FNR, send him some greetings from me (Paul from the camping, he'll know).
