Our first-ever Experimental Broadcast in Quadraphony with Radio 2 (for Stereo listeners only) With your front two speakers bringing you Radio 2 on VHF Stereo (88-91 MHz), and another Stereo Receiver driving your two back speakers and tuned to Radio 3 on VHF Stereo (90-92.5 MHz), you will be able to hear this programme in Quadraphony. If you only possess one Stereo Receiver, tune this to Radio 2 on VHF Stereo, and tune a Mono Receiver (preferably VHF) to Radio 3. placing this behind you: you will then be able to hear this programme in Triaphony, or, if you prefer, Triphony.
