The following recordings were made in 1971 by K3ZO and recently transcribed to WAV by K4GKD.
The recordings were made in Vinh Binh, in the South Viet Nam Delta
where I was serving as "Provincial Psyops Advisor" to the South
Vietnamese Government's provincial officials.
I had shipped my Drake
T4XB and R4B twins and a bunch of coax and wire, but at the time the
recording was made we had not yet succeeded in getting permission for
ham radio operation in Viet Nam.
We could move around the province without much difficulty in the
daytime, but the Viet Cong ruled once the sun went down so at night we
were confined for security reasons to an area comprising a few city
blocks near the center of the town where our offices and billets were
located. There wasn't a lot to do at night; you could get blitzed at
the NCO bar, some nights you could watch a movie at our provincial HQ,
or you could stay in your quarters and read Nero Wolfe novels and
other paperbacks that previous denizens of the advisory team had left
I chose to listen to the ham bands most evenings.
The rented house
which served as both my office and living quarters happened to be
located between two towering trees about 200 feet apart so I was able
to make up separate half-wave dipoles for 15, 20 and 40 meters which I
connected end-to-end with each other with insulators separating one
antenna from another, using separate feedlines for each band. The
local electric authority provided the services of an ancient lineman
who, armed with a long pole with a hook on one end and steps tacked
onto it, pulled himself up to the very top of each tree in turn and
mounted my end-to-end dipole array between the tops of those two
As you might imagine an office with "psyops" in its name had a few
tape recorders around so, in the absence of permission to transmit,
during major contests I actively searched for PVRC stations on the
bands and, on hearing some, hit the record button.
I thought the gang
might like to hear how their signals were being heard on the other
side of the world.
At the time I had no idea that these recordings
would serve as historical evidence of the dominance of the signals of
some of PVRC's finest.
