Light Aircraft Association

Before I took it out I had a similar problem with my KX 195 ( a dual 175 ) and Connington. My radio engineer said the 175/195 series uses two crystals, one transmits and one receives. As the crystal dies you find frequencies where you can transmit, but not receive, and vica versa. How old is the set ?

Now the war has ended it seems somebody wan't to make money.

When I was a lad, and Hurricanes were based at Kenley, I suspect the engineering officer burned the book !!
