I remember the drill like it was yesterday. Self-announce the 45-degree entry to downwind by shouting into the Telex hand mic, stow the Telex mic between the knees, power back, carb heat on and work in some flaps as the cabin speaker in the old Cessna 150 screeched with garbled combined radio calls from every Unicom within a 100-mile range. Those were the bad old days of flying without headsets, of course. Then I stepped up a layer in the food chain and blew my college partying wad on a David Clark headset and never looked back. I think my first model was the company's H10-30-you know, the set with the signature green domes, shiny mic boom and clamping pressure higher than a college-age teenager on a Friday night.
