I used to listen to Radio Peking back in thise days on an old Westinghouse
dual wave with randomly tuned long wire antenna, now that was entertainment!
All the funny nicknames they had for the allied forces in Vietnam....
Whatever happened to Peking? Did it go the same way as Mesopotamia, Bombay,
Ceylon and Rhodesia?
I didnt know what the LORAN /Woodpecker was caused by, I used to BS to my
mates that it was the "aircraft band" hehehe!


Regards
Peter
