Emergency Connections and Kit_

The ability to easily interchange equipment between stations may be crucial in an emergency. All stations active n the Amateur Radio Emergency Service (ARES) should use a common type of power connector throughout their stations, or they should keep an adapter on hand. Dick Rawson N6CMJ, writing in the June issue of Electronics Museum ARC newsletter, suggests Molex"* 2-pin (0.093-diameter pins), 12-amp connectors with a contact resistance of O.Q025 ohms. 2.5 mV/A, However, this connector is not suitable for ?ong-term outside use because it is not weatherproof

Make sure tnai polarization is the same from station to station, The POSITIVE pin is on the FLAT side of the connector and the NEG^ ATIVE is on the POINTED side. ¡Ed. Note: Standardization rs important between stations because some hams use an opposite polarity arrangement, myself included}. The source side of the connector (from the power supply) is the MALE housing with the FEMALE pins to be installed Tne radio side is the FEMALE housing, with the MALE pins to be installed,

Waldom Part No. 1545PRT, a package of three sets, contains Molex parts 03-09-2021 (plug), 03-09-1021 (receptacle), 03-09-1118 (female pins)T and 03-09-2118 (male pins). Radio Shack's one-connector set rs £274-0222.

In the May issue of the above newsletter, the editors state that rubber duck antennas and NiCd battery packs are severe handicaps during a prolongued communications emergency, NiCd batteries last only a few hours, so your emergency communications kit should include some alkaline batteries. As for antennas. you can quickly attach a J*poie 2m antenna to a school flagpole and hoist it up 30 feet, or throw it up over a tree branch with some nyfon rope and a rock /look carefully before you throw} A small generator or a deep cycle 12-volt battery can keep your 2m and HF radios operating * hen the power is out.

In addition to the right connections mentioned previously, your kit should contain: adapters, extra coax with lifting, AC power supply, large alligator clips on a power cord for using a car battery, and a high capacity (800 mAh) NiCd pack for your HT, A magnetic mount antenna and power cord with cigarette lighter adapter and a pair of earphones can come in handy, too.

Mary, a student of Rocco Laurie Intermediate School in New York City, was chosen to receive this award because of her many accomplishments in amateur radio in The short time since first exposed to it by Carole Perry WB2MGP (see Mary's interview with Carole in the May issue). Interested in other cultures. Mary has discovered the joys of contacting people all over !he world, as well as locally. Using borrowed radio equipment, on bus snps she has kept hundreds of students, some of them out of state, in contact with the school principal and hams who coufd help in case of mechanical problems or emergencies.

One of MaryTs favorite ham activities is participating in the ,LCQ Alt Schools Net," a hookup of dozens of schools around the country. Mary has developed a high level of compe tence in handling traffic, and her skili al operating various types of radio gear often astounds the more experienced devotees of the hobby Her irrepressible enthusiasm is quickly communicated to her classmates, and she enjoys helping them get started in amateur radio.

Mary says that amateur radio has helped her greatly in her school work, especially in geography and social studies, and that she is becoming increasingly interested in the scientific and experimental aspects of ham radio.

OTH-B, the Over the Horizon Backscatter radar system with transmitters in Moscow, Maine, and receivers in Columbia Falls, Maine, is only the first of four such systems to be built. A system spanning California, Idaho, and Oregon is now 90% complete. The central system will be based in North and South Dakota, and Minnesota The fourth system will be In Alaska. OTH-B has a range 10 times greater than that of conventional radar, and will be useful in detecting small drug-smuggling planes as well as serving as an early warning system,

OTH-B is also known as the "woodpecker" because the interference it causes in shortwave communications resembles the rhythmic pecking of this bird. According to GEr the builder, the transmissions will include the following frequencies: 5 MHz (what about WWV?)t 6.74-9,09 MHz (40m^)( 9.09-12.24 MHz (30mJ>j. and during the day, 12.25 to 16.50 MHz (20m). 16.50 to 22.25 MHz (18m and 15m), and 22.25 to 28 MHz (possibly affecting the 24 and 10m bands). And now Japan and Australia are also interested in set-ling up their own OTH-B radar systems!

However, Kokusai Denshin Denwa Co., Ltd in Japan has developed equipment which almost completely eliminates 'woodpecker11 interference without using noise-blanking methods. Al present, this new equipment is only used on ship telephones, but amateur radio use is under consideration. TNX Crosstalk, newsletter of the TRW ARC, The JARL News. and Amateur Radio Newsline.
