10th Anniversary Mississippi Memorial Event Set
"Many lost everything they owned and many lost their lives," said Larry Morgan, AG5Z, who is spearheading the event. "We also want to honor the hundreds of volunteers from all over the country that poured in to assist us in our time of dire need."
Several stations along the Mississippi coast will use special event K (for Katrina) prefix 1 × 1 call signs. Operation will begin on August 26 at 0000 UTC from home stations. On August 29 at 1300 -- the time of Katrina's impact -- all stations will reduce power to 100 W, except for bonus stations K5M and K5T. Reduced-power operation will continue until September 2 at 2359 UTC.
K5Z at "ground zero" will consist of a portable QRP station set up on the beach using temporary antennas and emergency power.
Certificates will be available. See the Katrina 10th Anniversary Special Memorial Event website for details. Send logs and QSLs to AG5Z. Morgan expressed his appreciation to the 599 DX Association and the Hattiesburg Amateur Radio Club.
to Conduct 9/11 Memorial Special Event
Jim Millsap, WB4NWS, District
EC for the Metro Atlanta District ARES, reports "We will be operating
from the Cherokee County EOC Ham Station and the Cherokee County CERT/ARES
trailer on HF frequencies in the General Class band of 20, 40, and 80-meters
on Friday, but the biggest event activity is expected on Saturday. Stations
are invited to check in on Friday or Saturday. A special certificate
will be provided to those who make contact and send a self addressed
#10 envelope." (More details will be provided on QRZ as the event
dates draw closer).
to End Mechanical Filter Production
"Over the past several years, we have seen a dramatic reduction in demand for narrowband analog filters," the company said on its website. "Due to this and other economic reasons, [Rockwell Collins] Filter Products will be discontinuing its mechanical filter products in the near future."
Rockwell Collins makes two different types of mechanical filters, many of which have found their way into Amateur Radio products and applications. In a mechanical filter, input and output transducers convert the electrical signal to and from resonant mechanical vibrations, respectively.
Collins has made mechanical filters for more than 6 decades, and their initial application was in telephone circuits. The filters gained favor for Amateur Radio use because of their excellent selectivity, especially in IF applications. It is said to take about 12 weeks to manufacture a single unit.

25 MHz Signal is Back on Original Vertical Dipole
"The antenna the 25 MHz [transmitter] is on right now is the original antenna it was on in 1977," Matt Deutch, N0RGT, WWV's lead electrical engineer, told ARRL. "When the 25 [MHz transmitter] was shut down [that year], the radiating section was removed and tossed in the bone yard, and a new longer section put on the tower to make it a 15 MHz stand-by antenna."
Deutch said that when WWV first reintroduced the 25 MHz broadcast in 2014, it used a broadband monopole. It was later decided to use that antenna for WWV's 2.5 MHz stand-by transmitter, though. "So, we decided to rebuild the 25 MHz antenna," he recounted. "A few weeks ago the boys dug the 25 MHz radiating section out of the mud in the bone yard and rebuilt the 25 MHz antenna, so that it looks identical to what it looked like in 1977."
Deutch said the 25 MHz WWV vertical dipole now is coupled to its own, dedicated transmitter, radiating 2.5 kW "with near zero watts reflected," he added, and modeling has showed that the dipole exhibits a lower angle of radiation than the broadband monopole did. "There is no automatic backup transmitter for 25 MHz at this time," Deutch added. The 25 MHz WWV signal had been operating at about 1 kW for the past 16 months.
Deutch has said that WWV has received reports on the 25 MHz signal from across the Atlantic. The 25 MHz transmission not only provides another option to check your frequency calibration or the exact time, it also can serve to indicate the state of propagation on 12 and 10 meters. The 25 MHz broadcast includes the same information transmitted on all other WWV frequencies and at the same level of accuracy.
Located in Fort Collins,
Colorado, WWV is operated by the National Institute of Standards and
Technology (NIST). WWV has invited listeners' comments and signal reports.
FCC Proposes Fining Georgia Ham $1000 for Failing to Identify
The FCC has proposed fining a Georgia ham $1000 for alleged failure to properly identify. David J. Tolassi, W4BHV, of Ringgold, Ga had been warned last August about not following the Commissions Part 97 ID rules. The FCC said his deliberate disregard of that warning warranted the proposed penalty.
Mr Tolassi...has a history of failing to comply with the rules governing the Amateur Radio Service, the FCC said in a July 22 Notice of Apparent Liability for Forfeiture (NAL). As the NAL recounted, agents from the FCCs Atlanta Office used direction-finding techniques to track the source of a signal on 14.313 MHz to Tolassis residence in Ringgold, Georgia.
The agents monitored and recorded transmissions during which Mr Tolassi failed to transmit his assigned call sign, the FCC said. The agents interviewed Mr Tolassi later that evening, and, while he admitted operating that evening, he denied making the unidentified transmissions.
Nonetheless, the FCC determined that Tolassi apparently repeatedly violated Section 97.119(a) of the rules. The Commission pointed out that it could have assessed a forfeiture of $16,000 a day for a continuing violation, but it settled on a $1000 fine.-ARRL Letter
