This information from the Radio 270 Rate Card, published 1 April 1966 but prepared many weeks before launch, by  Radio 270's Director of Engineering Peter Duncan. 

The Radio 270 coverage map shown above was based on VERY conservative estimated and ignores  the effect of the ship being sat out at sea, which gave the station much better launch of the signal into the ether as well as a 'shotgun effect' along the coast, enabling the signal to travel many miles in land.  The predictions also seem to ignore the local topography (hills, etc) and the ground conductivity which allow the signal to travel along fertile valleys, and lowlands like the Fens area north of Cambridge.

In practice, Radio 270 had listeners much further afield, certainly most of the UK,  thanks to the clear frequency that the station had chosen, as well as in most of Scandinavia, the Benelux countries and Germany. The furthest the station was heard was in the USA;  American radio  stations use frequencies ending in zero, so Radio 270's transmissions on 1115 kHz were a popular target for DXers being midway between two local stations.

Radio 270 also received many signal reports from listeners across Scandinavia where the signal was very strong - Svenn Martinssen in Stavanger, Norway, reported it as being the strongest of all the offshore stations on the Norwegian coast.  

Radio 270 had many listeners in the Netherlands, especially the Friesland area (north of Amsterdam) where the station was stronger even than Radio Veronica, which was anchored off Scheveningen.

Transmission

Radio 270- ship Oceaan 7, anchored in Bridlington Bay.  The aerial mast was approx 160 feet high; it held up the aerial cable which was hund just aft of the mast,. The feeder was connected at the top of the mast, by a short horizontal boom. This boom was electrically bonded to the mast, which formed the return leg to the aerial down to ground (the deck). The aerial was effectively a folded unipole.

The station's single transmitter was an RCA B10J, which was run at 2.5 or 10 kilowatts output. All the station's programmes were produced and presented from a single studio alongside the transmitter, just for'ard of the bridge.

Radio 270 Programmes.

The Radio 270 programmes were originally to run for 15 minutes and with the idea that they would be sponsored by the advertisers, similar to the way Radio Luxembourg had been run previously. But with local business doing the sponsoring these programmes were to be produced in the studios that Radio 270's Chief Engineer, Peter Duncan, had built in Newcastle. 

The plan was for most of these to be programmes of the magazine type, with a variety of topics discussed between the records.  There would be visits to local events and factories in the "Down Your Way" style and other visits of local interest to promote regional tourism etc.

A health advice program was scheduled and a Radio Doctor was planned. In addition, a Radio Vicar had been appointed, Reverend Hedley Pickard from Hunmanby, just outside Filey.

Quite a number of programmes had already been produced as well as some pilots, but these wouldn't be suitable for the new format. The new revised programme format would include more popular music and require a simpler method of delivery that could be easilly produced live on board the ship.

The new revised programme format would be more poplar music based and require a much simpler programme type that could be made and presented live from on board the Oceaan 7.
