Blimey, I had almost forgotten about Sunair HF sets. I recall spending a few hours setting the Antenna Coupler on new installations on Shorts Skyvan aircraft using a Bird Thruline Wattmeter to achieve the optimum VSWR for each channel. On one occasion I was still holding the clip to adjust the inductance when I pressed the transmit button which resulted in a nasty RF burn on my forefinger that took several weeks to heal properly. Painful lesson learned!
