More
repair work
Below
is a picture
of what we
call "H"
frames.
Antennas are
fed with open
wire and since
it is some
distance
between the
antennas and
the buildings,
multiple
wooden
structures
like this are
used. Over
time the
weather,
carpenter
bees, and even
termites make
it necessary
to get in and
do repairs.
Equipment
on the south
lead to the
antenna field.
This
type of work
requires
cranes,
boomlifts, all
terrain
forklifts
which are
costly and
efforts are
coordinated to
get as much
done per
deployment as
funds allow.

Correspondence
I saw
a unique
e-mail address
so I reached
out to Dale
VE7YTB and
this is the
wonderful
response that
came back on 2
August 2020.
Hi
Robert, Thank
you for your
email. We are
restoring a
1944 navy tug.
We are
modeling the
various
aspects of the
radio room to
reflect the
capabilities
of KPH radio.
We use tube
Marconi CM11
radio with
radiotelephone
and
radiotelegraphy
gear. We have
working RTTY,
a Wheatstone
perforator and
Boehme
transmitter.
KPH is a major
inspiration.
We
are very
lonely without
you on the
airwaves. We
sorely miss
your SDR site
as well.

and Thank You

RCA R3 Dual
Diversity
Receiver
The
unit in the
above picture
is an RCA R3
Dual Diversity
receiver which
resides in one
of the side
rooms at RS
(Point Reyes).
The receiver
is quite tall
as you see a
step to reach
the top
portions and a
handle which
is out of the
frame of the
photo.
An in
depth story
has been
written back
in 2012 and
some of us
were not
members or
subscribers so
rather than
redo a story I
will direct
you to a back
issue of the
MRHS
Newsletter No.
16 from 18
September of
that year.
Click
on the photo
to access the
back issue and
in depth
story.
Relay
This
small article
was in the
Spring 1968
edition of
Relay which
was a
corporate
publication of
RCA Global
Communications.
This
building that
currently
stands at BL
(Bolinas) is
where the
generator
mentioned in
the article
above was
housed.
Frequency
Measuring
Last
month some
frequency
measuring
equipment was
featured and
this
advertisement
was just found
in a June 1936
RCA Broadcast
Trade
Magazine. The
last address
listed is
Point Reyes,
California.

Thank you to
