I missed that, must have been introduced recently. Can you post the code section, so I don't have to read through that god-awful document again, searching for it?

He took the pin for #51 and clipped to his antenna and flew, and I observed the scanner light up channel #15. I told him about it and he seemed surprised, and slid the markers off his antenna & reversed them.
I'm glad he didn't shoot down someone or get shot down himself. I almost made that mistake when I bought two identical radios at the same time. While on the workbench, the channel flags got switched. When I turned on my radio at the field, another pilot's plane started chattering, fortunately in the pits wit hthe engint not running. Whew! Close call!
