Interesting post. Amazing what is hidden away in the records!

Interesting insight into the change over and use of Q-Codes. German Signals Intelligence during World War II came to the conclusion that some of the Soviet Air Force radio operators were being trained by British radio operators. Although that might be correct in some cases it was probably down to the Soviet adoption of international standard Morse Code with standard Q-Codes?

Some 70 plus years later the Q-Code is still very much in use by the military during Morse Code air-ground communications. Probably one of the last air-to-ground / ground-to-air Morse networks still in regular daily use?

The following recordings are from the Russian Naval Air Transport network on 8816 Khz during February 2012. A very basic use but obviously fulfills the need for air traffic control of Russian Naval transports such as Antonov 12 Cub and Antonov 26 Curl.

I've included the recordings links for those serving and retired that can copy Morse. How many Veterans out there thought that the use of Morse was consigned to history and especially for aircraft communications?
