Taken at RNZAF Ohakea, March 22nd, 1998 Under the hood: Some of the avionics exposed to public view - there's not much room up front. The two large black boxes are the VHF-AM transceiver (rear) and the UHF transceiver (forward). The small grey box ahead of these is the coaxial relay box. The small grey box to the left with two coaxial leads is the audio transformer box.
