The SNJ ARESMAT supports the 2021 New Jersey Triathlon - (Posted: 07/19/2021)

This past Sunday the 2021 NJ Triathlon was held at Mercer County Park in West Windsor, NJ. Earlier in the week the Ham Radio organizers requested 1-2 operators to fill positions at the beginning and end of the bicycle leg of the event. The SNJ ARES Mutual Assistance Team fielded a Type 4 team of three operators 1 for UHF/VHF Phone communications.

Operators were tasked with directing the riders to either complete a 2nd loop of the course or head to the end of the segment. Riders completing the first or second loops of the course were intermingled. This made it a challenge to steer them to the correct lane. All operators, event staff and local police worked together and did a great job keeping the riders on track.

In addition to the event’s stated duties, MAT members also cleared overhead branches from the bike lane, directed motorists to the park’s open entrances and even drove a spectator that had “misplaced” his car around the area.

This was the team’s first Public Service deployment and was a warm up for the MS City to Shore bike ride this fall.

Participating Team Members: Silke KC2ENS, Glen KD2FFR, and Tim NJ2N

 

The SNJ ARES Mutual Assistance Team consists of emergency communications operators from around South Jersey. If an SNJ County finds itself shorthanded during an emergency, ARESMAT operators will deploy to that county as needed to supplement the local EmComm group’s local operators. The local EC tasks the Mutual Assistance Operators as needed – in effect, they become his operators.

The SNJ ARESMAT is looking for operators to join the team. Any license class is acceptable, as is any experience level. For more information email: snjaresmat@yahoo.com

 

1)  A Type 4 Team is equipped with dual band HTs for Voice communications. Types 1-3 add Digital Modes (FLDigi/FLMSG and Winlink), HF, and HF Digital Modes. All team types can operate portable, on emergency power, and are self-sustaining for up to 72 hours.


Local Amateur Provides New Evidence of the Hindenburg Disaster - (Posted: 05/21/2021)

Not to long ago Bob Schenck, N2OO was at a memorial service for the Hindenburg disaster. He approached Dan Grossman, a renowned expert on airships, and mentioned that he had a film of the disaster his Uncle Harold Schenck had taken when it happened. His uncle had offered the film up at the time but no one seemed interested so it was actually a surprise when Dan Grossman jumped all over the opportunity to view the film.

This film showed the disaster from a totally different angle than all the news footage had shown. With the help of this footage and experts around the world a new investigation was started on how the Hindenburg actually exploded and many questions appear to finally be answered.

NOVA, a documentary series by PBS TV, just aired the story on Wednesday evening at 9pm. It can still be viewed from the PBS TV web page at https://www.pbs.org/show/nova/


Updated Radio Frequency Exposure Rules Become Effective on May 3 (as posted on arrl.org 4/12/2021) - (Posted: 04/14/2021)

The FCC has announced that rule changes detailed in a lengthy 2019 Report and Order governing RF exposure standards go into effect on May 3, 2021. The new rules do not change existing RF exposure (RFE) limits but do require that stations in all services, including amateur radio, be evaluated against existing limits, unless they are exempted. For stations already in place, that evaluation must be completed by May 3, 2023. After May 3 of this year, any new station, or any existing station modified in a way that’s likely to change its RFE profile — such as different antenna or placement or greater power — will need to conduct an evaluation by the date of activation or change.

“In the RF Report and Order, the Commission anticipated that few parties would have to conduct reevaluations under the new rules and that such evaluations will be relatively straightforward,” the FCC said in an April 2 Public Notice. “It nevertheless adopted a 2-year period for parties to verify and ensure compliance under the new rules.”

The Amateur Service is no longer categorically excluded from certain aspects of the rules, as amended, and licensees can no longer avoid performing an exposure assessment simply because they are transmitting below a given power level.

“For most amateurs, the major difference is the removal of the categorical exclusion for amateur radio, which means that ham station owners must determine if they either qualify for an exemption or must perform a routine environmental evaluation,” said Greg Lapin, N9GL, chair of the ARRL RF Safety Committee and a member of the FCC Technological Advisory Council (TAC).

“Ham stations previously excluded from performing environmental evaluations will have until May 3, 2023, to perform these. After May 3, 2021, any new stations or those modified in a way that affects RF exposure must comply before being put into service,” Lapin said.

The December 2019 RF Report and Order changes the methods that many radio services use to determine and achieve compliance with FCC limits on human exposure to RF electromagnetic fields. The FCC also modified the process for determining whether a particular device or deployment is exempt from a more thorough analysis by replacing a service-specific list of transmitters, facilities, and operations for which evaluation is required with new streamlined formula-based criteria. The R&O also addressed how to perform evaluations where the exemption does not apply, and how to mitigate exposure.

Amateur radio licensees will have to determine whether any existing facilities previously excluded under the old rules now qualify for an exemption under the new rules. Most will, but some may not.

“For amateurs, the major difference is the removal of the categorical exclusion,” Lapin said, “which means that every ham will be required to perform some sort of calculation, either to determine if they qualify for an exemption or must perform a full-fledged exposure assessment. For hams who previously performed exposure assessments on their stations, there is nothing more to do.”

The ARRL Laboratory staff is available to help amateurs to make these determinations and, if needed, perform the necessary calculations to ensure their stations comply. ARRL Laboratory Manager Ed Hare, W1RFI, who helped prepare ARRL’s RF Exposure and You book, explained it this way. “The FCC did not change any of the underlying rules applicable to amateur station evaluations,” he said. “The sections of the book on how to perform routine station evaluations are still valid and usable, especially the many charts of common antennas at different heights.” Hare said ARRL Lab staff also would be available to help amateurs understand the rules and evaluate their stations.”

RF Exposure and You is available for free download from ARRL. ARRL also has an RF Safety page on its website.

The ARRL RF Safety Committee is working with the FCC to update the FCC’s aids for following human exposure rules — OET Bulletin 65 and OET Bulletin 65 Supplement B for Radio Amateurs. In addition, ARRL is developing tools that all hams can use to perform exposure assessments.
