I found this site again the other day. It has some recorded radio air time from the Vietnam broadcasts over Armed Forces Vietnam Radio. The real time play is slow to impossible because the streaming is slow but if you do the download and play it....works ok.
Some things come back in the announcements every once in a while that remind me of the great differences between the support troups on big military bases and those who actually fought the war out there in the bush and on small firebases.
