foreign thing that has plagued Pirate Radio Stations since their migration from sea to land in the late 1960s has been getting caught most early land-based Pirate Radio Stations operated in one of two ways either they'd sit with their equipment transmitter an aerial system and do a live show or because this often wasn't viable they'd pre-record the shows onto tape haul the equipment to a suitable location and leave it all there while the tape played the show when the tape ran out they'd return and gather everything before leaving and this often meant that any station that was raided was unmanned as time went by the safest approach for live transmission was to use a studio to transmit a link to separate the two sites there were two main kinds of links Band 1 and microwave nowadays many stations use 4G which is virtually impossible to detect and I should point out they were also UHF links which used the same Principle as the band One links but these were less common the band One links could be traced easily but the microwave links were extremely difficult to trace Band 1 links were wideband transmitters within 48 to 70 megahertz they output only a few Watts with some going Beyond 20 watts although this really was Overkill not much power was needed because they transmitted at lower frequencies and of course lower frequency signals tend to achieve better ranges the signal was sent from the studio to the main transmitter site using a dipole with elements cut for the link frequency now because there wasn't a lot of spectrum between the link frequency and the main transmitter frequency it was possible that the main transmitter could overload the link receiver due to the close proximity of the Aerials it was better to horizontally polarize the bandwon receiving dipole and of course the main transmitter aerial was vertically polarized the band One link signal was picked up by a dedicated receiver built into the transmitter these links were problematic as the band was still relatively busy decades ago and it was very easy for both saboteurs and the DTI to trace these links with very little skill and minimal equipment these types of links often left Studios at risk of raids so another type of Link was utilized in the form of microwaves microwave links are completely different to Band 1 although the end result is the same they work on the basis of a modulated power supply connected to a microwave horn a type of antenna the link signal travels in a thin beam making tracking much more difficult but not impossible the microwaves are on frequencies between nine and a half and 11 gigahertz and can cover quite long distances in good areas the problem is that these frequencies atmospheric conditions tend to attenuate the signal even certain weather conditions such as snow can completely wipe out a studio to transmit a link microwave links a...
