I'd be very interested in the Comms fit history of the Chipmunk. My knowledge is limited to the 10 Channel Crystal Controlled 1985/86 Tx/Rx VHF config (see pics below and my previous pic on this thread of WZ845) and would like to know more on the UHF config ... outside the obvious UHF upper and lower blade aerial locations v the VHF quarter wave rod under wing aerial
I also experienced a 360 Bendix VHF config on WK518 before she moved to the BBMF.
