The war against PLT–seeing the destruction caused by BT supplied Comtrend PG902 UPA PLT adaptors

I have had another look on the Ban PLT website, a new video has been added, the video is by a licensed amateur showing what a pair of Comtrend PG902 PLT adaptors, the ones supplied by BT, can do to shortwave.  The results were that effectively the band is wiped out by noise.  Shortwave is part of the HF range 3-30 MHz, which includes some amateur radio bands, the CB allocations, as well as shortwave broadcasting.

Shortwave is still used by many people every day although most domestic radios sold these days lack the shortwave band, although the receivers are still obtainable and still used.

For some people from overseas, shortwave may be the only way they can hear news from their home country, these people may not have access to the internet and may prefer to listen to the radio.

Shortwave listening is a part of the Amateur radio community as well, even for those that are not licensed and thinking about taking the exam to get their foundation license, just because someone has an interest in radio does not mean they wish to transmit, shortwave listening is just as fun as transmitting.

So, do you have a pair of Comtrend PG902 PLT adaptors?
Do you use your Comtrend PG902 PLT adaptors?
Do you know that you are destroying a precious natural resource that people everyday need to use?
IF you answered “yes” to any or all these questions, unplug the adaptors, contact BT straight away, tell them you want an alternative (they HAVE to give you one) to the PLT adaptors, the BT Home Hub is a WiFi router, and most laptops built since 2004 have WiFi built in, but if the WiFi doesn’t work due to congestion, just run some ethernet cables, these can be discreetly run along the skirting boards and under carpets, or if you own the property you can have your home wired to contain ethernet cabling and sockets on the wall where you just plug your computer into, it’s a one-off hassle and causes NO interference to radio services.

You may not think of it as this, but the radio spectrum is a precious natural resource which is why many radio services require a license to use them, why radio equipment must meet certain Interface Requirements, and why all equipment, radio transmitters or not, must be tested to make sure that any RF emissions will not cause harmful interference to legitamate services, tests which all PLT adaptors, not just the Comtrend PG902, are not cabaple of passing, and although many seem to differ on this, they are a type of radio transmitter but they are spectrally unclean, causing unwanted interference.  I compare them to spark-gap transmitters from the early days of radio, which used large amount of spectrum and thus they are now illegal to operate, so it should be the same for PLT.

So, I urge you again, please stop using PLT adaptors if you have not already done so, and bin them, they pollute the radio spectrum, and we all need the radio spectrum every day, don’t take it for granted.
