Thanks to Tony King reporting on the DX Dialog reflector, here is a photo of Gary DeBock with his invention, the Ferrite Sleeve Loop. “Gary DeBock’s latest creation with which he is scoring many NZ stations on his Tecsun PL380. Probably about 200 ferrite rods on this “sausage roll” .pic attached. He’s in the right uniform, and his PL380 lives in an NZ emblazoned mobile phone pouch I sent him last year.” Rumour has it one or two Kiwis are building them!
And also from Gary is a Youtube video of his antenna picking up trans-Pacific DX from New Zealand.
