252 and 279 UK Long wave info
Hi,
RTE are currently using 300kw daytime 100kw nightime on 252, they've just added a new Optimod audio processor, so the audio is now much louder which should help with DX' ing the station outside europe.
Musicmann 279 is on track to be on air by the end of this year, possibly with 100kw initially (500kw possible later), and possibly initially from the radio ship 'MV Communicator', formerly used for the pirate station, Laser 558, before moving to an offshore platform permanetly.

Paul,
Thanks for sharing this EU LW BC information. Several of us Stateside like to listen for these stations and it's very helpful to have realtime information from your side of the pond.

Has anyone ever considered building a LF/1750 meter Echolink node? I know the echolink is traditionally associated with ham FM repeaters and VHF/UHF stations, but it is not restricted to only these modes/frequencies.
I could imagine a LF node (either RX only or TX/RX) on echolink. Someone with a vary favorable location and antenna for LF might want to create an LF echolink node to allow other Lowfers access to longwave activities. One could allow monitoring of LF activity, checking your own signal from another location, etc.
For those not familiar w/ Echolink, it is VoIP linking over the internet. It allows you to connect to, and control, a ham xcvr over the internet using the Echolink application software. Google echolink for more info. Re: Echolink and LF 1750 meters

Transceivers are not presently very common at LF, which is probably the main reason someone hasn't already tried this mode.
There are, however, a number of "grabbers" accessible over the Web at any given time...good receivers at quiet sites, feeding soundcard inputs and running spectrum analysis or decoding software, with the results posted to Web servers in near-real-time. There are some sites in Europe which monitor DX portions of 2200m continuously and 1750m occasionally. Here in North America, there are typically one, two or three grabbers running on any given day for 1750m, but the modes sometimes vary.
To keep track of whose grabber is monitoring what, one should subscribe to the LWCA e-mail Lowfer Group. Subscription information is normally available at the LWCA Groups page, but the self-subscription process is temporarily closed during the transition to a new server. To place a request for list membership, e-mail webmaster@lwca.org until the automatic process is restored.
John Radio ship planned to broadcast off Alexandria, Egypt
Posted by Mike Terry on April 09, 2005 at 10:56:49.
Was this an April Fool?
According to the website of Kabbary Antenna Technology, makers of the
Crossed Field Antenna (CFA), the world's first longwave radio ship - 500 kW
SP CFA at 162 kHz & MW 558 kHz connected to a 100 kW transmitter - is
planning to transmit songs & music programmes from Alexandria in Egypt.
The website also claims that the CFA installation on the Isle of Man planned
for 279 kHz will achieve a much wider target area of transmission than
planned. The site says that groundwave transmission can reach the USA and
East Asia countries for some periods of the day !!

Mike,
At first I didn't catch the drift of what you are saying. These guys are claiming a 500 KW RF output with a 100 KW input!! After reviewing some "misunderstood work of Tesla" they are seeing some increadible results... yah, right! What's actually happened is that after 2 years of chasing this down they have become as mentally 'far out' as Tesla became in his later years.

Perhaps that's what comes from messing about in the middle of high energy RF fields. Don't spend too much time poking your head through those loops, Bill, or you'll be talking to Martians like Tesla did.
Oh, I forgot...a CFA doesn't have an induction zone.
Just as it has "no skywaves" either. What a hoot! I suppose that's why the "groundwave" coverage to the USA is predicted to occur during...wait for it...the hours when the path is in darkness. Woo-hoo-hoo.
Enjoy.

Bill, et al:
From their literature, they aren't quite sure what is producing the large antenna gain. But they do offer this possibility:
"We think that the feedback power source is resulting from photon mass transfer into RF energy , through photon fission reaction or nuclear fusion of photon."
Two to beam up, Mr. Scott...

I guess it will be interesting to see what can be heard co-channel with France Inter (Allouis) on 162kHz. This will not please some users as Allouis is a longwave frequency standard transmission like BBC Droitwich (R4) on 198kHz.
With the voltages generated on a short aerial there should be quite and interesting light display of Alexandria.
Maybe I read is differently Bill (maybe too naively) I though it was 500kW at LW and 100kW at MW.....and the Med has a higher salinity than mose sea-water.

The transmitter Thule of the US Army
Posted by Harald on April 26, 2005 at 08:36:07.
Near Thule there is a 410 metre high radio mast. What was it used for? (I suppose for LF/VLF-radio services of the US Army) List of World's tallest radio masts
On which frequencies it was used?
When was it built? Is it still standing?
In some sources the height of the radio mast Thule is 385 metres high. Was it made higher? If yes, when?
Are there pictures (and construction drawings) available of it?
Posted by Harald on April 26, 2005 at 08:42:35.
On http://en.wikipedia.org/wiki/List_of_masts there is a list of World's tallest radiomasts. Although most of them are used for UHF/VHF-transmission, there are although some links to VLF/LF-transmission sites. If someone has more informations to the mentioned masts (I believe there are many US radiotechnicians active in this forum) they should add additional informations to the corresponding masts.

Harold - I worked there for a while and up at Alert NT but for the life of me I never remembered seeing that sized mast at Thule - I was there in 81/82 but had my head down looking at my feet most of the time, and perhaps it was built after I left

Hi all, have found time to get back to VLF after a few years of "too much work" Hosstraders Hamfest - Calling all New England LOWFERS
My old HF1000 blew a PSU and I chased thru the web to get it fixed. CONDOR were very helpful and I have to thank them for that. The Premium receiver email reflector guys have also been super helpful - a great group for hi perfomance seekers.
Anyway, glad to be back online. Wonder if there is an email sub for the mag ??

This coming Friday and Saturday May 6/7 2005 is the Spring Hosstraders hamfest in Hopkinton NH (near Concord). Please see the Hosstraders website:
http://www.qsl.net/k1rqg/
Anyone with an interest in LW is encouraged to call K2ORS on 146.445 FM or send me an e-mail in advance. I'm trying to arrange a LW get together and so far have 2 other Massachusetts LOWFER types confirmed. I'll be there both days unless the wx is really bad. Re: back on board after a few years away
On the agenda is a planning session for the Fall Hosstraders when we hope to have a live longwave demo and (tx & rx) at the hamfest.
