  • Notes

  • Roberts R700 has separate FM and AM reception units.

    Unusually for 1967 in the UK, the VHF-FM Coverage is to 87 to 108MHz. In 1955, many sets only covered 88 to 100MHz, this was later 102Mh, then 104MHz. Services such as Police used above 104MHz.

    Scale of many are marked with BBC1, BBC2, BBC3 and BBC4. BBC1 was created in 1967, which was also when Home, Light and Third were renamed to R4, R2 and R3. Early models (1966) might be marked Home, Light and Third. There are at least four different versions (colours changed) of the tuning scale, 1966 - 1969
