  • Annotazioni

  • The Trophy 3 AC is a significant model in the British Television Supplies, Ltd. (BTS) Trophy Series, representing a key evolution in the company’s acclaimed line of shortwave receivers. Introduced shortly after the Trophy 2, the Trophy 3 AC was designed for users seeking improved performance and convenience, offering mains-powered operation for continuous listening.

    Technical and Design Features

    • Power Supply: AC mains operation.
    • Tuning and Output: Enhanced tuning mechanism for more precise station selection compared to the Trophy 2.
    • Loudspeaker output: moving beyond the earlier headphone-only designs.
    • Frequency Range: The unit comes with two BTS One-Shot inductors covering 12-52 metres. Additional inductors are available to extend the complete wave range from 6.2 to 200 metres.

    Design
    The Trophy 3 was a TRF (Tuned Radio Frequency) receiver, typical for its era and purpose, offering straightforward operation and excellent performance for its class.

    Series Context
    The Trophy 3 AC & Trophy 3 Battery sits between the original Trophy 2 (battery-powered, headphone use) and the more advanced Trophy 5 (with features like band-spreading, B.F.O., and A.V.C.), offering a balanced mix of performance and accessibility. The top-end Trophy 8 further extended the series with additional refinements for serious enthusiasts.

    Price
    £6:6:0 with two one-shot inductors.
