Just to clear things up. Nutt's Corner was NOT a licenced model flying area. One of the military VFR routings from the ATZ boundary was via Nutt's Corner below 500ft with no lower limit. In certain areas of Northern Island we had an operational ceiling of 200 ft. AGL. When Aldergrove ATC was aware that there was model flying going on they would warn us but could not prevent OR allow it.
We tolerated it but when they got aggressive then we used this trick. The only mistake I made was that the set was a standard HF set used by long range Transport Command and had an output of 100watts, not 100 mw.
