The main transmitter is down for maintenance "soon", and to be replaced by a (presumably) lower powered device.

BTW a RF3 sees Droitwich off for me,  but I'm 100 miles away.

Just Noticed 198Khz is back broadcasting, lowering snr on tone 46 to 7.25db from 34db, and affecting the others next to it by them decreasing by 2-3db

I personally find that it's pointless, as it is available through tv,fm,dab radio, the sooner am stops broadcasting the better  >:D

But it keeps my Casio radio watch accurate and I didn't have to put it right for BST either.

You are quite right, 4candles. I take it Anthorn is the new location for Rugby which has closed? I'm just so out of date!

Aye, Rugby shut down in 2007.

I believe the timing on some Economy 7 electricity tariffs is still controlled by coding on 198 kHz.

Plenty more opportunities until June/July for those experimenting with QLN graphs when Radio 4 LW is off air -

I get all my RFI from radio China international 7310 kHz and 198 kHz does not effect me at all on fttc.

After installing Iplate it seems tone 46 is not being used as the QLN spike is larger? :lol: Opposed to the second QLN before, Second pic

Although everyday they are turning 198khz on and off it kills my adsl connection, with errors galore it will come back on at about 5:00pm, even though the tone affected isn't in use the connection still stops working! 250khz-254khz also when this is enabled the surrounding tones also loose around 6db per tone. This is now really frustrating >:(

Loading;  in another forum someone removed breakthrough from the 3 Moorside Edge transmitters  which were all of 1 mile from him !

Suggest :=
1) mainly for overhead lines use RF3 ( included in I Plate)
2) for pickup on 'phone extensions, use filtered faceplate ( NOT I plate) to stop 'phone extensions acting as aerial.
3) If these are not a 100% cure, consider filtering/spacing from 50Hz wiring.
