I'm trying to find out what type of backpack radios the Chinese and North Koreans could have had during the Chosin Reservoir, if any (Specifically the Chinese but info on the North Koreans would be helpful as well). I'm looking for something that was similar to the US SCR-300. I read an account that said they had some old unreliable Soviet Radios but it didn't have any more info and I'm not an expert on Soviet Radios. I have a feeling the North Koreans would have had better radios if any as it seems they were better equipped by the Soviet Union. Any info would be much appreciated!
