The commentator says the first live TV broadcast of the rugby
international was 80 years ago, in 1938. How did they do that? There was only one transmitter (Alexandra Palace) and the match was presumably played at Murrayfield or Twickenham. Would GPO lines be used? Which system was used - Baird or Marconi? |

Should read 1938, I know but I thought the commentator said 1937.

The year sounds plausible as, according to Christopher Martin-Jenkins in his book "Ball by Ball: The Story of Cricket Broadcasting", the first ever television cricket coverage was from the 1938 Lord's Test between England and Australia (page 57). -- John Hall "Hegel was right when he said that we learn from history that man can never learn anything from history."

According to Radio Times listings from genome.ch.bbc.co.uk the first broadcast of Rugby was 19 March 1938 at 1450hrs. There was a broadcast from Wimbledon (for the Davis Cup) seems to have been on 24th July 1937 when the transmission was described as a "relay". Looking on tvobhistory.co.uk it seems to have been transmitted using "wireless" technology but THE first OB was the 1937 Coronation on 12th May when the "newly laid balanced pair cable" was used from the site at Hyde Park Corner. |

Fairly easy to get line of sight from all three sports venues mentioned to Alexandra Palace, so probably just wireless relay. Although both Baird and EMI system were used from the start of broadcasts in November 1936, the 405 line electronic system was predominantly used (and remained in service for nearly fifty years apart from the war). |

So more likely to be 1938 at Twickenham (which Scotland won !!!) than 1937 at Murrayfield. What would the wireless relay look like? |

Fairly easy to get line of sight from all three sports venues mentioned to Alexandra Palace, so probably just wireless relay. "Murrayfield" is in Edinburgh, so a bit difficult to get line of sight to Alexandra Palace. But, I could see it from my bedroom window when growing up. Although both Baird and EMI system were used from the start of broadcasts in November 1936, the 405 line electronic system was predominantly used (and remained in service for nearly fifty years apart from the war). As I said, the EMI 405 service was formally abopted (to the exclusion of the Baird system) in Feb 1937. Up till then the service was a mix of the wo systems. -- from KT24 in Surrey, England |

There's a description in Pawley - but no pictures: A frequency of 64MHz was used..... At the OB end a 1¼kW transmitter was used. mounted in a vehicle. ... using an aerial supported by two tripod masts 30ft high, The use of open wire feeders for a high transmitting aerial presented difficulties, but in 1938 a flexible lightweight cable was produced by co-operation between the BBC and the Telegraph Construction & Maintenance Company. This permitted the use of an 80ft fire-escape to support the aerial, which enabled it to be erected in about 5 minutes. there is then a reference to: T.C.Macnamara, "Outside Broadcasts in Television", World Radio, 22 July 1938. -- from KT24 in Surrey, England |
