LW transmitter Droitwich 198 kHz power ??

Get several discussions about de power of Droitwich which is stated at 500 kW. Recpetion in the Netherlands is very weak so one is suggesting that they cut down the power. It used te be very strong in The Netherlands. I made some investigation but cant find any message about power reduction.
So what is going on there ??

P.S. I myself don't have any problem living in Middelburg only 4 miles from Northsea coast. Even on a portableradio .


Kind regards from a radiofreak PA3ALX Herman Middelburg

The station may have tweaked its antenna array to rotate the lobes (signal maxima) toward some other "more desirable" geographical area that was previously in a weak-output zone. That of course means that some previously-well-covered areas will receive weaker signals.

This presumes that Droitwich uses directional antennas; which they may, or may not, do. However, it is an alternative explanation to an output-power reduction.

Yet another explanation is that the station's antenna farm is undergoing extensive maintenance/repair during which time they are operating on a backup antenna array with different radiating characteristics.

Excerpted from Wikipedia:
"In 2011 as part of the BBC cuts it was announced that there would be no re-investment in long wave which may mean an eventual end to BBC Radio 4 in this part of the radio spectrum. It was later announced that the transmitter relies on a pair of metre-high glass valves that last between one and ten years. There were fewer than ten remaining in the world, and the corporation was not inclined to go to the expense of manufacturing new ones."

It may be that the station has dialed back its RF output power somewhat in order to maximize the life of these economically-irreplaceable transmitter tubes.
