British mast owner Arqiva on the block and attracting international attention

Many thanks to SWLing Post contributor, Dave Porter (G4OYX), who shares the following item from The Telegraph:

An array of international infrastructure investors from the US, Asia and Europe are sizing up the £6bn mobile and broadcasting mast giant Arqiva as its current owners prepare to put the company on the block.

The crucial infrastructure provider, currently owned by Macquarie and the Canada Pension Plan Investment Board (CPPIB), is being eyed by at least half a dozen buyers, City sources said.

Discussions are at a preliminary stage, with a formal process to begin in the next few weeks, but known suitors include CKI, the Hong Kong-listed holding company controlled by Asia’s richest man Li Ka-shing. […]

Dave once forced the Shipping Forecast to repeat a broadcast

Droitwich transmitting station (Source: Wikipedia)

Our post yesterday regarding the Shipping Forecast reminded me of a story SWLing Post contributor, Dave Porter (G4OYX) once shared. Dave writes:

I worked at the Droitwich Transmitting Station through 1972-1974, the home of the BBC UK Long Wave 1500 m/200 kHz service as it was then.

In the summer of 1973 I was junior member of the engineering team, a 21 year-old Technical Assistant, and manned the control room for the four services from the site, Radio One, 1214 kHz, Radio Two, 200 kHz and Radio Four, 1052 kHz.

It was customary to check the two 200 kW transmitters, T7A and T7B for power balance prior to the Shipping Forecast and I duly went out in the transmitter hall just before the start at 1355.

I noted one was a little down and the other a little high so I pressed what I thought was the raise / lower buttons on the control desk. Unfortunately I had pressed the main on/off buttons instead.

The pair of transmitters came instantly off the air. I could hear on the audio monitoring the announcer starting the broadcast… it takes a while to reinstate the mercury arc rectifiers as the regulators had to run all the way down to zero and then back up to 14 kV.

By the time I had got it back on the air he was just finishing so we had to contact London and arrange a repeat after the 1400 news bulletin… Ooops!

I was much more careful after that when adjusting the transmitters.

The Senior Maintenance Engineer was not best pleased, as he had to write up the shutdown report for London citing “Operational Error” as the cause.

Happy Days…

Dave G4OYX.

That’s a brilliant story, Dave! Thank you so much for sharing. Oh…I’m sure it’s a lot easier to laugh about it now than it was when it happened! 🙂

Paul receives report confirmation from BBC test transmission

SX-99-Dial-Nar

Many thanks to SWLing Post reader, Paul Walker, who writes:

Remember the “transmission tests” from Babcock and Wooferton last summer? I finally got an email QSL…

My original email is first along with an audio sample of what I heard….

Original message sent on Tuesday, August 11, 2015:

I wanted to send you a reception report after hearing your broadcast.

“This Is A Test Transmission” on 15745khz heard at 1655UTC/11:55am Central today (08/10/2015) in Beaumont, Texas (far southeast corner of the state). This is 4 1/2 minutes, recorded until abrupt sign off in mid song.

I used a Sangean ATS909X with a PK’s Loop 6-18mhz tuneable Shortwave loop. The loop can be tuned to a certain frequency with a dial and can be rotated.

Tuning the loop to your exact frequency and orienting it in your general direction resulted in a pretty decent signal with good audio. The signal was about a 5 out of 10 with some fading, but generally pretty steady.

A link to the 4 1/2 minute audio clip is here:

Do you offer QSL’s? I would very much appreciate a QSL card or letter via regular mail if that is possible.

Warmest Regards,
Paul Walker

Fast forward to yesterday (Wednesday, January 27, 2016):

Thank you for your report and I confirm the details are correct. These transmissions were to fault-find on a 300 kW sender at the UK HF transmitter station at Woofferton.

The engineers needed a long test time as the fault was of an intermittent nature.

Babcock, Woofferton is the only remaining UK HF sender broadcast station and also is the only one with this transmission test audio and email address.

The audio is contained in a file playout system and incorporates non-copyright music and voice announcements from one of the employees at the transmitter site.

Thanks for your interest.

Dave G4OYX,

(Retired) Senior Transmitter Engineer Woofferton 1982-2012.

Very cool, Paul! And many thanks to Dave Porter for supplying Paul’s confirmation!

If you haven’t already, I would highly recommend Dave Porter’s video presentation of Woofferton on YouTube (https://www.youtube.com/user/wooffertonuk) and this history of WOF (http://www.bbceng.info/Technical%20Reviews/technical_reviews.htm).
