Those aren't his, but I understand that Ed Henry ( of Henry Radio Amplifier fame? ) did some radio related cartoons, too. Perhaps he was better known for his "Microhenry's" cartoon, which ran for years in Model Airplane magazines. It featured a little guy with a big hat, almost always holding an RC transmitter ( long antenna sticking out ! ) and making some kind of wise crack, or watching in dispair as his airplane came crashing out of the sky !
