Some shots of the 252Khz Longwave transmission tower in Co. Meath, Republic of Ireland, currently broadcasting RTE but originally erected for Atlantic 252. Pictures taken Sunday 17th March 2013.
I don’t normally go out of my way to photograph broadcast sites – I usually prefer to think and talk about the content rather than the technology – but a friend in the UK asked me for some pictures, and as I was walking in a forest only about 20km away today I thought “why not?”.
So there you have it, 252 site on a typically misty St. Patricks Day.
Have a listen to the tests of the custom-built AM valve transmitter on board the Radio Seagull ship in Harlingen, Netherlands, as picked up more than 300 miles away in Co. Kildare, Ireland
I reported during the summer on the construction of a custom built, old-style valve transmitter for high-power AM on board the Radio Seagull ship, the Jenni Baynton, located near Harlingen, in the northern Holland. For the last 6 weeks this transmitter has been in use, performing authorised tests on the 1395AM frequency, which is licenced to a different operator. During these tests Radio Seagull has been relayed, and they come to a close after this weekend (14th November 2011) after which Seagull will continue to be heard on its own frequency 1602Khz and online worldwide.
For the last week, the transmitter has been operating on a higher power setting, and in addition to providing coverage throughout The Netherlands (the intended coverage area) it has been possible to listen much further afield, the signal reaching many parts of the UK, and latterly Ireland.
Click on the link below to hear a short (1 minute) sample of reception on an ordinary car radio, at Monestrevin, Co. Kildare, at around 5.45pm on Monday 7th November. This recording was made simply by using to “voice memo” function on my mobile phone to record the sound inside the car, so the original reception quality is even better.
Not a bad reach for a hand-built rig on a little lightship. Kudos to Walter, Colin, Sietse and the the onboard engineering staff on the Jenni Baynton.
OK, this one is for the more technically minded radio enthusiasts.
Out here on board the former lightship Jenni Baynton, our engineer Walter Gralle has been building a copy of one of the old-fashioned high-power AM transmitters as used on the offshore stations of the past. This is similar, apparently, to a transmitter used on the Caroline ship Mi Amigo in the 60s.
Below are some photos of this magnificent piece of valve- driven transmitting equipment, which is nearing completion.
