Here in Gallery 2, I have included some images from flying in the continental USA and out to Hawaii, with a couple of photos for the aeronautical radio and milcom listeners. Who recognizes the frequencies on the HF radios?
I'll give the answer: The Air Force uses 8.992 and 8.776 MHz for relaying Emergency Action Messages and sometimes other voice traffic. The amateur frequency 14.178 is popular among operators developing Enhanced Single Sideband stations. The HF gear on the 757 and 737 don't have a wide enough banpass to receive all of the voice spectrum these hams transmit, but the clean amplitude processing and minimal phase distortion is easy to hear!
My other favorite photo is the 737, at Chicago Midway Airport, being unloaded under the scrutiny of armed couriers. I went out for a preflight, and noticed the rampies unloading box after box of currency. We literally had a truckload of greenbacks on board with nary a word to the crew!
