September Program:

Homebrew Rig and Gadget night!

Tuesday, September 1, 1998

Our Program for the September Meeting of the Athens Radio Club  will be "Homebrew Rig and Gadget night." So dust off all those nifty construction projects you've done and bring 'em along.

See you Tuesday, September 1st.

The President’s QSO

by Ken Schroder, N4NFI

Well, the UGa students are back. If you've been driving in Clarke County in the last few days you don't need me to tell you that. The traffic is really heavy, with some big time traffic jams in places like College Station Road in the mornings. Usually, people talk about Labor Day being the official end of summer, but in college towns like Athens, I think the first day of classes marks the end of summer. Or perhaps its the date of the first home football game. Either way, summer is about over and its time to shake off the summer doldrums and get back to the "real world." Once again, the club will be helping the Red Cross with communications during UGa home football game this year. This is probably our most consistent and significant public service activity during the autumn. And with 6 home games you can really work around your other weekend activities. The first game is Saturday, September 5th. Plan to meet at the T-Bones parking lot on Baxter Street by 3pm. Bob, KE4JLL is coordinating this, so if you have any questions please let him know.

Well, we had a real nice Family day Picnic and Fox hunt last Saturday. I'd guess we had 20+ in attendance. Lots of good fellowship and lots of good food. Thanks to all who brought a dish and to Phil, KE4TYV for getting together all the club supplied hot dogs, drinks, plates etc. and for serving as grill chef again this year. Thanks also to Ed, N4ALE who served as foxmaster. The fox was found first by Dave, KE4EOI and then by Phil, KE4TYV. Several interesting antennas were used and Jerry KC4JRL reports that when he was entering the park, the attendant in the gatehouse was talking on the Parks Dept. radio with another employee who was asking about the "guy running around with the antenna" That had to be Phil, who had a 3 element beam mounted on a piece of PVC pipe. Most people recognize a yagi as an antenna when they see one. The fellow probably thought Phil was a wildlife ranger tracking a bear or something. Ed, N4ZRA had a single element quad which would have looked at home at the head of a religious procession and Scott, KD4MSR must have drawn some stares as he walked around with his HT down in a quaker oats can covered with aluminum foil. It's hard to be inconspicuous on a fox hunt :-) A good time was had by all participants. Ed, N4ZRA wants to organize another fox hunt for sometime later this fall. Watch the Emitter for details.

Don't forget Homebrew Rig and Gadget Night, Tuesday, September 1, 7:30 PM at the club shack. If you built it and you're proud of it (kits included) bring it along and show it off!

73,

Ken

Scanner Corner

Part 3 of a 3 part series.

In a previous article I touched on the subject of locating frequencies. To explore that concept further I want to excerpt from an excellent posting by Bill Parnass. Mr. Parnass is a frequent contributor to publications like Monitoring Times and Popular Communications. He also posts to the newsgroup rec.radio.scanner and makes this information available to us in that format.

Examine the FCC License on Premise

I have found the actual FCC radio license, complete with frequency assignments, hanging on the walls of places like the Bell Labs security office and the guard shack at Waste Management's Greene Valley Landfill in Naperville.Examine the Labels on Radio Equipment Frequency information is engraved on labels on the back of many walkie-talkies, or inside the battery compartment, like in the Motorola HT220 model. Most pagers have labels on the bottom or inside. Like passwords taped ontoterminals, it's not uncommon to find Dymo or P-Touch tape labels embossed with frequencies or call letters glued to the front of base stations. You can make your own opportunities for eyeing the equipment or take advantage of "open house" events. If information is displayed publicly, then a reasonable person could assume it's not government secret.

-At the annual Glenview Naval Air Station open house, Iexamined a military manpack radio being used by dispensary paramedics. The radio's tuning dial was set at 34.15 MHz.

- The Illinois Army National Guard displayed two armored personnel carriers at the local county fair, eachequipped with VHF-FM and HF-SSB transceivers. In addition to a tuning control (VFO), the VHF-FM radio had a set of channel select pushbuttons, much like those in a car radio. I asked a guardsman a few questions about the radio, and he demonstrated thechannel preset feature. A panel above the channel pushbuttons was labeled with the frequencies: 32.055, 34.45, 35.35, 40.55, and 40.60 MHz.

- An Army National Guard UH1 helicopter was displayed at the Marseilles armory "open house". The public was permitted to climb aboard, and observe the instrumentation and radio gear. A channel plate on the instrument cluster listed over a dozen frequencies.

Hobbyists are urged to exercise a modicum of restraint and good judgement. In New Jersey, a radio technician/hobbyist called to service a transmitter in a county building, noticed a new unattended repeater installation in the same room. Being curious about what frequency this repeater was on, he opened the access door to copy the frequencies from the radio's crystals. It turns out that this radio belonged to the US Secret Service, and opening the access door could have activated a "tamper alarm"! The tech was skating on thin ice. He had nobody's permission to tamper with that equipment.Another source of frequency information is as close as your nearest Radio Shack store. Some Radio Shack stores make a local frequency list available to assist their scanner customers. Be sure to ask. Stores located in shopping malls almost always know the mall security frequencies. I often check the frequencies programmed into the floor modelscanners, too.

Examine the Antenna to Determine Frequency Band

You can often determine a transmitter's frequency band by the size and type of antenna used. The Police Call Plus book contains sketches of antennas. Antenna catalogs are crammed full with antenna pictures and specifications and they are usually free. Contact   Antenna Specialists (216-349-8400), Cushcraft (603-627-7877), Tessco (800-472-7373), Maxrad, Larsen Electronics (800-426-1656), and other companies in the land mobile equipment business.

Equipment to Determine Frequency Usage

If you don't know the exact frequency, but have a general idea of the range (e.g. 150 - 152 MHz), use your scanner's "search" mode. Most programmable scanners afford the ability to search between two frequency limits set by the user. Some models, including the Radio Shack PRO-2035, ICOM R7000/R7100, Bearcat 2500XLT, and Bearcat 250, have the ability to automatically store active frequencies found during an unattended search operation. To find the frequency of a hotel communications system, one fellow installed his Bearcat 250 in his car and parked in the hotel lot, leaving the scanner in the "search and store" mode. He left the antenna disconnected so the scanner would only respond to a transmitter in the immediate vicinity. Test equipment can aid in the quest for new frequency information. I've used a spectrum analyzer connected to an outside antenna, another spectrum analyzer connected to a receiver IF stage, and a frequency counter for close-in work.

How Can I Determine To Whom I'm Listening? - An Example

While scanning the industrial frequencies in the 150 MHz range, a van driver was overheard communicating with "base" while driving around my town. The stations involved never used FCC call signs -- this would have made life a lot easier for me, and legal for them! (one may use FCC license microfiche, described earlier, to identify stations using call letters.) Transmissions were short and infrequent, so it was decided to tape record all transmissions on this frequency for several days to determine the station'sidentity. During daylight hours, a modified Regency K500 scanner was left tuned to the target frequency, connected to a cheap tape recorder through a home built interface. Using a carrier operated relay, the tape interface supplied power to the recorder only during radio transmissions, so a day's worth of traffic could be compressed into a 45 minute tape.Each day, the tape was played back and notes on names, locations, and activities mentioned during the day's transmissions were taken. The van driver appeared to be making daily stops at a local bank and two shopping malls. A Walgreen's store seemed to be the only stop at one mall. A few times, "base" ordered the van "back to the Training Center." There were frequent references to "guests checking out", "dropping a guest off", and "instructor[s]missing a class". At times, "base" spoke with "security",who must have been using a walkie-talkie as his signals weren't strong enough to hear. Was this a hotel? Calls to the three local hotels revealed that none provides shuttle bus service to the shopping malls. A call to the Walgreen's, inquiring about bus service to the store, drew another blank. During my shopping trips, I began to pay closer attention to vans with antennas driving through the parking lots. I was leaving the mall one day, when a week's effort paid off. A maroon and white van, equipped with a VHF-Hi antenna, was dropping shoppers off at Walgreen's. A sign on the van's door read: XYZ Central Training Center (XYZ is a pseudonym for the actual licensee name.) Lisle, Illinois I watched the driver pick up a microphone, and listened to him on my portable scanner checking back with his "base". All the pieces fit: the "guests", the "classes", the "instructors". Mystery solved; I had been monitoring the customer training center for a large computer manufacturer. The training center has hotel rooms and dining facilities to accommodate students from out of state. As a convenience, shuttle van service is provided to local shopping malls.

Summary

Through books, government records, and radio clubs, scanner listeners can make use of frequency information compiled by others. Two-way radio users often fail to identify their transmissions properly, making it more difficult for listeners to know who they are monitoring. By examining radio equipment labeling, and monitoring and taping transmissions, scanner enthusiasts can unearth new information.

THOMAS E. "ACK" ATKERSON, W4RRW, SK

Tommy "Ack" Atkerson, W4RRW, of Jasper, Georgia, died August 2. He was 66.
The owner of Ack Radio in Atlanta and Birmingham, he had recently retired
to the North Georgia mountains. Atkerson served in the US Air Force before
joining his dad, W4ECI (also known as "Ack") in Ack Radio.

Tommy Atkerson opened the Atlanta office and then took over the supply
company when his dad died. Atkerson sold ham gear for many years, but when
Collins, Drake, and Ten Tec left the dealer market Ack Radio concentrated
on electronic supplies. "Tommy was always smiling, and that's what we will
miss most," said Southeastern Division Assistant Director David Thompson,
K4JRB. Atkerson's son Steve (not yet a ham) now runs Ack Radio. The latest
Ack Radio catalog has pictures of W4ECI and a young Tommy.--thanks to

Memories of Ack Radio
by Don Bullard, WA4IML

My first visit to Ack Radio took place when I was about 13 years old. I
wasn't yet a ham but I had learned the code and wanted to put up a "real"
antenna. That included RG8 coax and copperweld antenna wire. I talked my
father into taking me down to Ack Radio one Saturday morning (Now they are
only open weekdays). Then as now they were located on Deering road just
off Northside Drive in Atlanta. Five days a week my father drove to Atlanta
to work. Getting him to agree to one more trip down Roswell Road and
Peachtree Road wasn't easy. I guess my mother must have talked him into
making the trip.

Up to this time I had worn out numerous Allied Radio and Lafayette Radio
catalogs just dreaming of owning a Drake, Collins, Hammarlund, or
Hallicrafters rig. On that glorious Saturday I got to actually see up
close, new Collins and Drake radios as well as various other used models.
This place was filled with all kinds of electronic components. Just being
near all this great stuff was exciting. There were several hams also
visiting Ack on that Saturday. It was fun and at the same time intimidating
hearing them talk about their hobby. I didn't have an elmer and my
understanding of radio was so limited. I was happy that day just being able
to spend my grass mowing money on 50 feet of coax and some wire.

After our visit to Ack Radio my father took me to the Yellow Jacket
Drive-in for lunch. We ate hot dogs actually cooked in beer- pretty
exciting stuff to a youngster. My father said they weren't very good but to
me they were the best I had ever eaten. I think this is what we would call
in today’s lingo, quality time.

Ten years later I returned to Ack to buy my first, quality ham receiver, a
used Drake 2B and a 2CQ Q-multiplier. I regret ever selling that receiver.
It can hold its own on the ham bands even today.

Over the years I made many trips to Ack Radio; sometimes just to look at
radios and pickup a magazine and sometimes to actually buy a needed
component. I never actually knew Tommy Ackerson but he waited on me
numerous times. Having Tommy wait on me was similar to going through the
lunch line at the Varsity in Atlanta. I better know exactly what it was
that I wanted or I'd wind up stammering and stumbling my way through the
order and feeling like a complete idiot.

It seems like Ack Radio has been around forever. It's too bad they aren't
the ham radio store they once were. However, it's good to know that after
all these years they're still in business. I’m just sorry that Tommy did
not have more years to enjoy retirement.
