Signal Comparison
The analogue signal levels at Brougher Mountain transmitting station are quite high, with the old analogue signal level reaching 100kW.
In comparison, the current digital signal levels are significantly lower, ranging from -7dB to -23dB.
Here's a breakdown of the current digital signal levels for different transmitters:
Transmission Frequencies Over Time
In the early days of radio, transmission frequencies were much lower than they are today. The first commercial radio broadcasts in the 1920s used frequencies around 550-1500 kHz.
AM radio, which dominated the airwaves for decades, operated on medium wave frequencies between 535-1605 kHz. These frequencies were chosen for their ability to travel long distances.
The introduction of FM radio in the 1940s brought higher quality sound to listeners, using frequencies between 88-108 MHz. FM's higher frequencies allowed for better sound quality and less static.
The development of television broadcasting in the 1950s required the allocation of even higher frequencies, typically between 54-806 MHz.

Analogue vs Digital Signal Levels
Analogue signal levels can range from 100kW to as low as 1000W, depending on the specific signal. For example, analogue signal levels for BBCA, D3+4, and BBCB are (-7dB)20kW.
In contrast, digital signal levels are significantly lower. For instance, the digital signal level for SDN, ARQA, and ARQB is (-17dB)2kW. This is roughly 10 times lower than the analogue signal level for BBCA, D3+4, and BBCB.
Here's a comparison of analogue and digital signal levels for different signals:
As you can see, digital signal levels are generally lower than their analogue counterparts.
What's Going On
Brougher Mountain transmitting station has been experiencing some issues, and I'm here to break it down for you. The station's reduced power output has been causing problems for nearby residents, with some reporting poor reception and snow on all four channels.
Living eight miles away from the mountain, one user noticed a significant drop in reception quality, with channels breaking up or disappearing altogether. This is likely due to the reduced power output, which was noted on the Engineering pages of Ceefax.
The reduced power output is expected to last until October 27th, which is a pretty long time for those affected. For now, it's business as usual, but I'm sure many are eagerly awaiting the restoration of full power.
If you're one of the many people relying on Brougher Mountain for TV reception, you might want to check if you're experiencing any issues. One user reported seeing the TV transmission coming from about 50 miles away, which is definitely not normal.
Here are some key dates to keep in mind:
