My son, Stan, snapped this photo as I was making my first contact with the BC-610-I on May 2, 2009. The transmitter was running 115 watts output as measured by the Bird meter on top. The receiver used (in background) was a Collins R-388.
I contacted VE6SSC, the Edmonton (Canada) Space and Science Center. The operator, Charlie, said my 20 meter CW signal sounded good
with no chirp. It took several months to get me and the BC-610 ready for that first contact.
WW2 ERA TCS-13 TRANSMITTER AND RECEIVER ON THE WORK BENCH. THEY WORK WELL WITH THE HEATHKIT POWER SUPPLY.
BUT I DON'T HAVE THE PROPER CONNECTORS. ANYONE OUT THERE WHO WOULD BE WILLING TO PART WITH ONE OR MORE OF THE CONNNECTORS FOR CASH?
My vintage Collins station. On the bottom is a Collins 32V-3 that I have restored. The low voltage
transformer was commercially rewound. I re-installed the transformer, replaced a couple of tubes, cleaned contacts, and did some
cosmetic work and made the first CW contacts with the transmitter on June 30, 2009, with good reports. I am now
looking forward to an AM contact with the transmitter - my first in 50 plus years. Above the 32V-3 is a Collins Signal
Corps R-388 receiver.
My eldest son, Stan and I put together this small homemade radio telescope with an 18" Direct TV dish and
a Channel Master signal strength meter. The signal strength meter is powered by 12 volts from the satellite receiver.
It easily detects radiation from the Sun as shown by the change of signal strength of the Channel Master 1004IFD analog meter.
It also detects geosynchronous satellites along the Clarke Belt.
We plan to permanently mount it on a short tower, add
software, a computer and perform drift scans of the sky.
The idea for construction came from an article appropriately called "Build a Homebrew Radio Telescope" in the June,
2009, issue of QST. Another article refers to it as the "Itty Bitty Telescope." See
www.aoc.nrao.edu/epo/teachers/ittybitty/prodedure.html Stan is shown working on an A/D converter for the Itty Bitty Radio Telescope.
A radio telescope with a seven to ten foot dish is our next project.
1950's Sucker Stick Xmitter
CLICK ON THE PICTURE FOR LARGER IMAGE. This 1950's transmitter using a single 6v6 tube was constructed
on wooden strips by Jon Zoller (now deceased), W5ZWQ of Tulsa, Oklahoma. The coils were wound on sucker sticks. A
second set of coils can be seen to the right of the transmitter. My first transmitter was an identical one that I
constructed using an article titled "A Simple Transmitter" in the 11th edition of
"How to Become a Radio Amateur".
WN5VID
The slightly blurred picture on the left shows my novice station WN5VID at Amarillo AFB, Texas, in
early 1952. The small sucker stick transmitter is on the right side of the table.
I recently found my long lost 1952 log book and the picture of my novice station. Using my log book
as reference, I found that I used the sucker stick transmitter from March 22 until June 24, 1952. If I counted right,
I made 79 CW contacts while operating on 80 meters and running 4 watts. On
June 26, 1952, I replaced the 4 watt transmitter with an Eldico 60 watt transmitter and the frequency of my CW
contacts went up dramatically. I sold the sucker stick transmitter to John Tudenham, W0JRP, who was also stationed at
Amarillo AFB. John told me recently, "I used the rig and modified it to work on 10 meters and added a 2E26 final. I
constructed a 10 meter dipole laying it on the floor, and actually made a few skip contacts." Shortly after selling
the sucker stick transmitter to John, I was transferred to Sheppard AFB, Wichita Falls, Texas. In October I
acquired my general class ticket with the call W5VID.
On the far left is my late 1952 Amateur Radio Station W5VID at Sheppard AFB, Wichita Falls, Texas.
The military high frequency receiver
(lower) is a BC312. A 60 Watt Eldico CW transmitter is on top. I have tried to recreate my original station with
the same equipment (to the right) in the year 2002 --- my 50th year as a radio amateur.
My circa 1952 Eldico TR-75 CW transmitter is shown at the top. It has coils wound for 20 meters
(my favorite band).To the right is an MFJ-267 dummy load and to the far right is a red variac to ensure that the
input AC voltage of a WW2, BC-312 receiver on the shelf below stays close to 110. The receiver has an external
power supply to the right. The
BC-312 runs really hot with the power supply in the case.
At the bottom is a Collins 310 C-1 with
PTO (VFO) and home made power supply. An extenal T/R switch on the back of the BC-312 changes the antenna from transmit
to receive and mutes the BC-312 receiver through the PL-114 connector on lower right. Resting on the 310 C-1 is a
Hallicrafters tube operated keyer. To the right is a Signal Corps LS-3 loudspeaker.
A pair of military headphones hangs by a nail from the bottom of the first shelf. A Radio Shack 22-306 Frequency
counter is used to check transmit frequencies.
On the right rear wall is equipment for an amateur television repeater for the Bay Area.
The repeater is 434. MHz ATV in and 923.25 MHz ATV out. The 33cm amp output is
35 watts. The Bay Area Amateur Television Society (BAATS) is sponsoring the ATV station. The repeater call is
W5VID/ATV. Please do not buy any equipment to work through the repeater until all tests are finished and the repeater
antennas installed. Changes are possible as tests continue. The 70 cm collinear vertical receiving antenna and the 900 Mhz
transmitting vertical are installed on 20 foot poles. They will be installed on a top of a 45 foot tower shortly.
Anyone in the Bay area care to
volunteer a location for the repeater on top of a tall building?
The repeater is not fully operational at this point with tests being continually made. The TV on
the right shows the
picture being received. The TV on the left monitors the picture being sent.
BAATS was formed on Friday, March 20, 2009, by Frank Cooper, W5VID, and John Cole, W5AUH. My amateur television station is at the rear left. This includes a PC electronics 70cam 20 watt
transceiver and a 33cm converter. See
our web page at www.baats.tv
Please e-mail me if you would like to support the
repeater and join BAATS.
Contact on 70cm ATV
CLICK ON THE PICTURE FOR A LARGER IMAGE. Above is a picture of W5AUH and me during a contact on 70cm
ATV. I am monitoring my own transmissions on a 10" TV (left) while taking a photograph with my digital camera. I
am receiving W5AUH's 70cm picture transmission on the 13" TV on the right. John, W5AUH, lives in Pearland, Texas,
11 miles from my QTH. We are both amateur seismologists and compare wave forms from incoming earthquakes via ATV.

Earthquake Recordings
CLICK ON THE PICTURE FOR A LARGER IMAGE. Above is a picture taken of my two TV monitors while in
contact with W5AUH on 70cm ATV. On the 10" TV on the left I am showing W5AUH the wave forms of an earthquake in
progress as being inked on my chart recorder. Conversely on the 13" TV on the right W5AUH is showing me the wave
forms of the same earthquake in progress as being recorded on a chart recorder at his home.
70 cm AMATEUR TELEVISION LOFTED BY RED WHITE AND BLUE BALLOONS
Above is a picture of my wife, Pat, and several of the neighborhood kids after sun-set as she reeled
in 3 foot red, white, and blue balloons hoisting W5VID's 70 cm ATV transmitter and video camera called "SkyEye" to
get a sky view of the neighborhood on Friday, January 3, 2003. The 11 element 70 cm antenna can be seen in the lower
part of the picture. A small TV/VCR powered by a 12 volt battery was used to receive and record the video. The
local police investigated the launch saying they had had many calls inquiring about the balloons including one from
a woman who thought that perhaps terrorists were about to drop a bomb.
This is a view of "SkyEye." The orange painted balsa box contains two 9 volt re-chargeable batteries
(left), a small board video camera with sound(center), and a PC Electronics ATV 70cm transmitter (right). A
home-made ground plane antenna is on the right.

The Crosley 51
CLICK ON THE PICTURE FOR A LARGER IMAGE. On the left is a 1924 Crosley 51 regenerative broadcast radio
receiver with matching Crosley 51 A Amplifier. I purchased the Crosley 51 from a ham operator in Bellville, Texas,
for $30. more than 25 years ago. It was in very poor condition and I spent many hours restoring it. It is unusual
in that it has a wooden face. It has two 01A tubes, a book condenser, and one stage of audio amplification. The
amplifier uses one 01A tube and has one stage of amplification. I own many other vintage radios
such as an AK Radiodyne breadboard, a Marconi 106D crystal receiver and a pre-WW1 spark transmitter, but the Crosley
with matching amp is my favorite. I have collected vintage radios for more than 35 years and was the founder of the
Houston Vintage Radio Assn. in 1978.
