Hurricane Center Communications Test – May 28

National Hurricane Center Annual Communications Test to be Held on May 28

WX4NHC, the amateur radio station at the National Hurricane Center (NHC) in Miami, Florida, will hold its annual communications test on Saturday, May 28, 2022, from 9 AM to 5 PM EDT (1300 – 2100 UTC).

The event is designed to evaluate WX4NHC’s amateur radio equipment and antennas at the headquarters in Florida, and to give operators an opportunity to evaluate their home equipment prior to this year’s Atlantic hurricane season, which starts on June 1 and runs through November 30. This event allows ham radio operators worldwide to hone their amateur radio communications skills for times of severe weather.

Brief contacts will be available on many frequencies and modes, as well as the exchange of signal reports and basic weather data with any station in any location.

WX4NHC will be on the air on HF, VHF, UHF, 2- and 30-meter APRS, and Winlink at wx4nhc@winlink.org (subject must contain “//WL2K”).

The Hurricane Watch Net 14.325 MHz frequency will be active for most of the test, as will 7.268 MHz, depending on propagation. Depending on man-made noise, the net may move to different frequencies, and participants can locate the net using one of the DX spotting networks, such as the DX Summit website at www.dxsummit.fi.

National Police Week Special Event – K3FBI

National Police Week Special Event – K3FBI – 0000z May 15 through 2359z May 21

National Police Week offers honor, remembrance, and peer support, while allowing law enforcement, survivors, and citizens to gather and pay homage to those who gave their lives in the line of duty.

In 1962, President John F. Kennedy signed a proclamation which designated May 15 as Peace Officers Memorial Day and the week in which that date falls as Police Week. Currently, tens of thousands of law enforcement officers from around the world converge on Washington, DC to participate in a number of planned events which honor those that have paid the ultimate sacrifice.  National Police Week 2022 in United States will begin on Sunday, May 15 and ends on Saturday, May 21

The National Law Enforcement Officers Memorial

K3FBI – The FBI AMATEUR RADIO ASSOC (FBIARA) was formed Circa. 1991 from a group of amateur radio operators who were FBI employees and would get together on the air. This became known as the “BuNet”.  K3FBI became the club call in the fall of 1998, just in time to be an official part of the FBI’s 90th anniversary.

Group Kit Project? Who’s Interested?

Sean, KC3SZH brought this to my attention this morning and I have to agree this would make a good club kit project.  The cost of the antenna is $69.95 I think the club could cover the shipping for a group buy.  This is an End Feed 10,15,20,40 meter band antenna good for POTA and SOTA work.  It can handle up to 250 watts so full size rigs are usable with this antenna. We would order the kit and then assemble them up at the club.  Drill out the holes, wining the coil, and a little bit of soldering.  So if this would be your first kit time kit you would have the support and supervision of some of the club mentors.

If you interested please email me at n3lrg{at}w3kwh{dit}com the kit will cost you $69.95

Basic SKYWARN Training

On Wednesday March 9th there will be a in-person training session on how to become a Basic SKYWARN Spotter. It will be held at the Allegheny County Emergency Services located at 150 Hookstown Grade Rd., Moon Twp, PA, 15108 at 7:00 PM. Those that are interested can contact Robert Gerlach

Welcome to the Pittsburgh, Pennsylvania National Weather Service SKYWARN™ program. SKYWARN™ is a group of trained severe weather spotters that report directly to the National Weather Service.

Year after year, reports from SKYWARN™ observers have assisted the NWS in issuing timely warnings based on REAL-TIME reports throughout our 36 County Warning Area covering parts of PA, WV, OH, and MD. The NWS’s primary mission is to issue warnings to protect life and property.

Inside story ARRL Hurricane Maria

This is a very interesting story of one of the people that the ARRL deploy to Puerto Rico during the Hurricane Maria.  The story covers how to got there and what they had to go just to get on the island.  Then once on the island what they had to do to become the communication back bone for the whole island.  Include in his talk is what worked well and a tough review of things that could be improved.

SWL – Weather Fax Images

Every wonder what other beeping and buzzing sound off the ham bands are.  Or do you wonder how ships at sea get weather reports.  Well the Nation Weather Service still transmit fax weather maps out on the HF bands.  They have stations in Boston, New Orleans, Pt Reyes California, and Kodiak Alaska they transmit 24/7 on assign frequencies that you can find in this document. So how do you decode and view an fax image on your computer you use the good old FLdigi program the same one you use for decoding RTTY and PSK31 data.  From the OpMode menu item you select WEFAX and the the particular mode is called WEFAX576.  It does take about 10 minutes to receive an full fax image but once set up FLdigi will do all the work. Then just tune to the frequencies listed in the document for example 8.5039 Mhz for New Orleans  and center the tone so that they are around 1500 Hz in the FLdigi waterfall this will then let you set up your filtering to cut out adjacent noise on the the frequency.

If your image starts to look like it slide to the right or left you can adjust the “SLANT” to get the image vertical. You can also use “ALIGN” to center the image on your display. It does take about 10 minutes to receive the whole fax image but FLdigi will store the image automatically at the end of the broadcast. Now different station transmit different images. I have notice that Pt Reyes show the Pacific ocean images and New Orleans show the southern Atlantic image.

The Red Cross of the Greater PA Region, EMCOMM Team invites you to a “virtual” presentation on the Amateur Radio Emergency Data Network (I.E. AREDN) Mesh network.  Doug Hayward (K8DRH), an EMCOMM Team member in SWPA Chapter, has arranged for Orv Beach (W6BI) to present on this technology.

https://www.arednmesh.org/about-us   (Background Information on AREDN)

Orv is an early joiner and contributor to AREDN and has been very involved in furthering this technology in the California area.  He gives presentations on this topic including theory, equipment, and application of this to amateur radio.  He is also active in coordinating the network expansion in Southern California.

Please join us for Orv’s overview of AREDN on this ZOOM call. (link below).  Please feel free to share this link with other who are interested.
