Number 3 on your Feedback c.rd RX. • • EDITED BY LINDA RENEAUKA 1UKM Bill to Protect Amateur Radio On January 3, Rep. Jim Cooper (o-TN) introduced H.R. 73, a bill to prevent the loss of radio spectrum by the Amateur RMlio Service. Cooper is a member of the House Subcommittee on Telecommunications and Finance. where the bill is likely to be sent for consideration. H.R. 73 is also known as the Amateur Radio Spectrum Protection Act of 1991. The legislation proposes that "the Federal Communications Commission shall not diminish 9lt:isting allocations of spectrum to the Am. ateur Radio Service after January 1, 1991 . The FCC shall provide equivalent replacement spectrum 10 the Amateur Radio Service lor any frequency reallocation afterJanuary 1, 1991." AARl President Larry Price W4AA welcomed Rep. Cooper's support of the Amateur Radio Service and expressed the hope that many congressmen will join him as co-sponsors . Says Cooper: "I've come to believe that amateur radio operators are a valuable national resource, and I hope to see that they keep the necessary radiO spectrum to enable them to be around for many years to come." Congress found that (1) there are more than 490,502 licensed amateurs in the U.S.; (2) the amateur operates with a solely personal, nonpecuniary interest; (3) one olthe basic purposes of the amateur Is to assist in emergency communications; (4) amateur radio operators have reliably provided emergency communications; and (5) the FCC has taken actions (see the next news item) which resulted in the loss of over 100 MHz of spectrum to amateurs. TNX ARRL via MC/mailo' HAMNEr; and W5YI Report . 220-222 Bailie Lost The fight to keep the lower two megahertz of the 1.25 meter band from reallocation appears to be over, and ham radio has lost. On December 5, 1990, the U.S. Court of Appeals lor the District of Columbia Circuit denied the ARAl petition for review of the FCC order reallocating 220-222 MHz to the land Mobile service. In rendering its decisiOn, the Court concluded that by law it had to give great deference to the views 01 the Commission. It also stated that it could not say that the Commission did not arrive at a reasoned decision abou t the best way to advance the public interest, convenience, or necessity. The ARAl and the amateu r community have no other legal recourse open to them other than clear legislation by Congress. Editor Art Reis K9XI of 220 Notes spoke with ARRl General Counsel Chris Imlay N3AKD, and learned that the appeals court was the last stop in the legal process. The FCC is now in the position to set a date when hams must vacate 220-222 MHz. Meanwhile, UPS is going to have to share the "new" 220-222 MHz " land mobile" band with the military. The Army requested and was , granted an experimental license permitting its use 01 the entire 1.25 meter band . The Army plans to conduct basic research in buried mine detection in the Arizona desert using 2.918 megawatt ERP transmitters and sensitive receivers mounted in helicopters. loral Corporation has developed the new system and will be overseeing the tests under the callsign KA2XAV, which expires on May 1, 1992. The signal bandwidth will be 10 MHz with a 100 nanosecond pulsed CW duration. Before the 1979 WARC, the military informed the FCC that it would not require access to the 1.25 meter band aher January 1990. Recent developments in tne Middle East may in part be responsible for the military's decision to retain access. The type of research, and the geographical conditions under which it is being performed, make this appear very likely. TNX Wesllink Report, Numbers 591, 592. U2MIR On the Air Soviet Cosmonaut Muss Manarov U2MIR, one of the first operators who brought amateur radio to space two years ago, is back on the air from Mir. During his last tour of duty, lasting 366 days, he spent much of his free time operating primai rly on 145.55 MHz simplex FM. A new packet radio selup is now operational on Mir. You can connect to Musa's BBSbythe command C U2MIR-1 when he is not operating live packet on 145.55 MHz. Also included is a voice synthesizer to transmit bulletins in Russian, German, and English. The Mir station uses a higher power multi-mode amateur transceiver than the one in SAREX operations, and the antenna is mounted outside of the space vehicle. These two items, plus Mir's 51 degree orbital inclination, make U2MIR's station accessible to most hams worldwide. TNX Westlink Report, Number 592, and N6BVU. WAC with 50 mW After building the FIRE-BALL transmitter from the November '90 issue, Mike Mayer W5ZPA of New Orleans set out to work as many countries as he couio on 10m . Using just 50 mW on 28.060 MHz, Mike worked all continents in under 10 days! He now has a total 0116 countries and 20 states. Included in his list was a contact with the ZS9Z DXpedition at Walvis Bay, proving that you don't need muttikilowatts to wOfk those rare ones! TNX K7fRK and WA6YPE. Half aBillion Miles ••• On September 27, 1990, a new record for low power comm unications was set. Bill Brown WB8ElK, operating from the W2NSD/1 ham shack at 73 headquarters, successfully copied a 2.89 IJW CW message on 28.638 MHz transmitted by Bob Moody K71RK in Palestine, Texas . Bob was using a keyed HP-608D signal generator hooked up to a 3-element beam. Based on a distance of 1502 miles. this works out to over 519 million miles per watt . Young Speakers Wanted Carole Perry needs good speakers and presenters under 18 years of age for the Dayton Hamvenlion this April. She will be presenting " Youth in Ham Radio." She also urges every ham to bring a nonham child or young person to the Hamvention. Carole's address is at the top of her co lumn, "Hams with Class," in this issue. Satellite News AMSAT-oSCAR-10 is supporting Mode B transponder operations. Apparently it is receiving sufficient solar panel illumination. The transponder may be used carefully at all points of the orbit except MA 254-006 when eclipses occur. If beacon or transponder signals show Signs of FMing, users should cease all transponder use immediately. Both of Fujl-oSCAR-20'S transponders, JA and JD, have been turned on by the command stations. It was determined that transponder operation has little effect on the internal battery temperature. Since mid-August, FQ.2O has been in a noneclipsing orbit. which means it has been constantly in sunlight. The battery temperature has risen to abou t 40°C. For normal operation, the battery temperature should be between 0 and 5 degrees. The command team for FD-2O will be moni loring the lelemetry, and if they judge it necessary fOf the satellite's well-being, they may, withOU1 warning, tum off the transponders.
