Are you SURE that's where these transmissions are coming from?????
Absolutely sure! Under 'The history of 648' The website refers to both 648 and Orfordness, although I see that it does not definitively link the two. However, I know personally both the transmitter engineer and electrician who set up 648 AT Orfordness. I have been in contact today, discussing the set up re on site loops and broadband connections. Hope that helps.
We all have opinions. Mine is mine, yours is yours. Don't tell me yours is mine. I think that I was wrong once, but then again, maybe I was wrong!!
Thanks for the clarification number6. We wondered if those masts were still standing-having been out of comission for several years. You can tell the engineer and electrician that the daytime signal into Notts was very good- but rapidly deteriorated once it started to get dark.
I sincerely hope there is a good 4G signal at Orfordness!!!

Test-transmissions have stopped shortly after noon today - they said they'll come back with another round in due time so the only thing we can do is wait and see I assume if all was successfull (and it really seems like that even far more than expected) they now have to build a link from studio to Tx as all what we heard the last 2 days was just an ' endless audio tape ' - Though I wonder why they just cannot use an i-net stream. But there obviously isn't any i-net access at the Tx site as they would have done so if there was

Alec.. PM on the way.

Alec. If you say transmissions were far more successful than expected- wouldn't Ofcom be asking them to turn the power DOWN?? You see - this would be the flip side of the coin- and large companies like Global would be busily canvassing Ofcom to say that Caroline had managed to get the signal way beyond the designated area in the Licence. Personally- I don't trust Global an inch. Their puny signal from Quarndon doesn't get more than a few miles after dark. How long are they going to put up with a competitor having been allowed FIVE TIMES what they were????

Quote: BigJohn wrote in post #73BY the way - I heard that the actual frequency used last weekend was 647 kHz.
At times, yes I saw it as that, but I found it later to be locked on to 648. I imagine that the aerial hadn't been used for a while it was "warming up".

Here's a bit more info on it (Nicked from elsewhere!): "It’s a 60m grounded tower, shunt fed at the top, with the skirt wires pulled out to a diamond shape. The angle of these wires is adjusted to achieve 50R-J0, which it does present at 648kHz - so there’s no atu needed. In addition there are vertical wires running down the outside of the tower to increase its electrical width and preclude any resistance across the tower section flanges. It’s a variation of the ‘Marconi’ antenna."

And me- but it sounds good. So was there an exisiting 60m grounded tower still standing at Orfordness??? And did they modify it-or was it already modified for 648 during BBC World Service days??? Don't forget the World Service transmissions were directed AWAY from the UK- so the aerial would have been directional in those days. So maybe- they modified an existing tower? There are loads of questions, But I must admit for a power of 1kW they have made the very best of it.
It is an existing mast. It was the backup for BBC WS, so, already tuned for 648. Omnidirectional, unlike the HIGHLY directional main mast. Tbh, despite many times the power used for BBC WS, the null was so deep, WS reception here wasn't a great deal stronger than this weekends tests. Only downside is the signal's totally wiped out here on the south coast after dark by a Spanish station.

Yes- Cookie-that IS the downside. Daylight reception is great-but nighttime abysmal. On the opposite side- the 1368 RCN/Manx broadcasts get even better AFTER dark here- and very soon will become unencumbered by the BBC Radio Lincoln's 2kW transmitter. Its being turned off in January- I hope in time for the next RCN broadcast on the 21st!!!
