What's it all about?

Please see below for a brief description of the types of signals you will here on Bristol Channel Radio
  1. HAM Radio
    HAM Radio operators, also known as Amateur Radio operators, are generally private individuals and/or clubs and associations that operate their own radio equipment. Although groups of HAMs come together on air for arranged 'nets', HAM Radio does not include any form of commercial broadcasting. HAM from around the globe can be heard regularly on Bristol Channel.
  2. Morse Code
    Once the staple of spies and the military, Morse code, or CW is still a thriving form of communication. The CW heard on Bristol Channel Radio is generally being transmitted by HAMs, occasionally you may hear something interesting from an 'out of band' frequency.
  3. ADS-B 1090 MHz
    ADS-B, or Automatic dependent surveillance – broadcast transmissions are tiny data packets from all commercial, and some military aircraft. The data transmitted includes call-sign, speed, height and position info (and more). Using specialist software Bristol Channel Radio is able to use this data to plot the aircraft on a simple map of the Bristol Channel. (no audio)
  4. Marine Band
    The Bristol Channel is home Avonmouth / Portbury Docks, a key UK shipping port, both historically and today! Several ships from around the world can always found in the channel, there are also several Coast Guard / RNLI stations in the area, this can make for quite interesting radio.
  5. Air Band
    Having two international airports in the area and sitting under the main flight path to the US means that the skies above the channel are often very busy. Because of this the air bands can get extremely busy on VHF, but you'll also sometimes here signals from the lower HF bands, these signals are heard over a huge distance and used by aircraft approaching UK airspace.
  6. Strange Sounds
    One of the great things about radio is that it can be used by anyone, anywhere, for almost any purpose. The result of this is that you can hear all manner of weird and wonderful signals from all corners of the globe. Some of the signals make sense, but others are mysterious, at least to us.
