300 HrWannabe;
Actually totally legal. One of my machines has no electrics and an Icom radio. Last year I flew that non-radio from East Anglia to Eaglescott. I trained on non-radio machines, and believe me when you have ops/guard/handling/atis going continually in one box and ATC in the other while at work the peace and quiet of a non-radio day is heaven.
