Hi Rod 🙂 Still got one of Andy's mixers 😊 excellent equipment and possibly still in opposition in some broadcasting studies 🤔 the L shaped 7 antenna was enforced 1/8 wave because of limited space 🌌 as the ship I believe was only 180 foot long 🚫 558 aerial input only 12kw and quite often decreased to 6kw 💯 963 from the Ross Revenge at that time was 35kw ☢️ signed strength on land showed 558 to be a fair bit stronger 😥 Walter
