Radar also doesn't play very nicely with 2.4GHz radio links, as used on the majority of BBC News vans I've seen recently. If you're in the wrong place at the wrong height, you can struggle to get a usable signal back.

On analogue, it's characterised by a loss of sync and subcarriers at a regular interval, causing pictures and audio to jump / wobble. With digi-links, it often causes sufficient packet loss (on all recievers if in diversity mode) to render the stream unrecoverable, or to drop out until the next intraframe.


Yep - I think most of the digital rad cams currently in use are aroun 2.4GHz - and the COFDM system doesn't cope well with impulse noise like radar.

That said - even camcorders can suffer from it - though they usually have to be closer. It is a nightmare on navy vessels.

No countdown at midnight tonight. Just a static / frozen 'BBC News 24' logo after the weather until Chris Eakin appeared a minute later at the TOTH.

Virtually all the hand-held digi-links are on the 2.4GHz. I have seen one of the few 3.5GHz Gigawave Digital kits in the country, but I think they stopped making them almost as soon as they got it working successfully due to the uncertain future of the 3.5GHz band for PMSE use.

All the LINK kit I've seen & used (as I've seen appearing on the BBC Vans) has all been 2.4GHz based.

Caught this a few nights ago before HardTalk played out, it might be of some interest:

That is the very reason why non-news VTs have early vision or black from -3 to 0 rather than a clock running all the way to 0.

(And live BBC shows are no longer allowed to run from a clock and have to run from early vision at -1 or instant start if their titles have black up to 0... Of course this is the way the "New BBC" tries to stop clocks going out - it doesn't fix the systems or training - no it stops the clocks being used at all... Of course this now means VT PasBs no longer have a decent ident on them...)

Pointless bit of information about news VTs: On some VTs, I believe the countdown reduces to the bottom corner at around -10 seconds whilst being CSOd over early vision. I think it's used on the titles VTs for some networked American news bulletins, to create an error margin so if the local stations opt in too early, it doesn't look too ugly.

Slight mishap with the graphics earlier:

There has also been problems with the straps. This afternoon during a headline round up the strap with the headline appeared followed almost immediately by the "BREAKING NEWS" strap, then another headline and the "BREAKING NEWS" strap again. And the cycle continued. In the end they seemed to give up and remove the straps completely.

Also, after the BBC One lunchtime summary BBC News 24 played out a pre-recorded weather forecast with Laura Tobin instead of Dan Corbett. It had a night time blue opening and ending backing. I assume these are used overnight usually.

Yea...and by this time, it was midday and they took the "tour around the country" - detailed outlook, with the clock at 08:00! Confused

I've never seen them used on air.

Doesn't surprise me to see who's on air.

It hasn't been a double though, Maxine was in for the morning and the BBC One summary, although she did say Good Afternoon, even though the bulletin was 11.50 today. I imagine it didn't even cross the mind of the person writing the script.
