Weather Update – 3/12/2020

From NWS:

The Storm Prediction Center has updated their severe weather outlook for tomorrow to include most of Middle Tennessee in the slight risk area. (That’s 2 on a scale of 1 to 5.) The SPC writes that “All severe hazards appear possible,” meaning that there is the potential for large hail, damaging straight-line winds, and a few tornadoes. The best chance for severe storms appears to be during the afternoon and evening, along and ahead of a strong cold front that will be coming through tomorrow after dark. Severe weather season in Middle Tennessee runs from March through May, and we are definitely in it. Please make it a point to have multiple ways to get your warnings. Don’t rely on just one method, especially in the middle of the night.
UPDATE: It is very difficult to narrow down the timing to a more specific range other than “afternoon and evening” because there may be multiple waves of storms. There isn’t a specific time window when all the storms are going to come through. There will likely be some sort of squall line along or just ahead of the cold front, but there may also be scattered storms that develop hours in advance of the front. Please monitor your weather alert radio.

The scheduled March 7 SpaceX CRS-20 mission to the International Space Station (ISS) will include the initial Amateur Radio on the International Space Station (ARISS) Interoperable Radio System (IORS) flight unit. The IORS is the foundation of the ARISS next-generation amateur radio system on the space station. The ARISS hardware team built four flight units, and the first will be installed in the ISS Columbus module.

A second flight unit expected to be launched on a later 2020 cargo flight will be installed in the Russian Service Module. NASA contracts with SpaceX to handle ISS resupply missions.

The IORS represents the first major upgrade of on-station ARISS equipment. The package will include a higher-power radio, an enhanced voice repeater, and updated digital packet radio (APRS) and slow-scan television (SSTV) capabilities for both the US and Russian space station segments.

The IORS consists of a custom-modified JVCKenwood TM-D710GA transceiver, an AMSAT-developed multi-voltage power supply, and interconnecting cables. Once at the space station, the IORS will be stowed for later installation.

ARRL Creates New HF Band Planning Discussion Group


ARRL has created a new HF Band Planning Discussion Group. HF Band Planning Committee Chair Mike Raisbeck, K1TWF, will moderate the group, which will focus on the ARRL HF Band Planning Committee’s recommendations and other band-planning activities. Earlier this month, the ARRL HF Band Planning Committee invited comments and suggestions from the Amateur Radio community on its report to the ARRL Board. At the Board’s January meeting, the committee presented its specific recommendations in graphical form for each HF band and each US license class, with the goal of increasing harmony on the HF bands, particularly between CW and digital users. Those responding to the initial call for comments and suggestions are encouraged to cross-post their remarks to the new HF Band Planning Discussion Group.

Amateur Radio Emergency Service (ARES®) volunteers in Puerto Rico continued over the weekend to report for daily duty at an American Red Cross (ARC) distribution center in Mayagüez and at ARC Headquarters in San Juan. The two sites are at the ready to provide a “Plan B” communication backbone in the event the seismic situation worsens. A magnitude 6.4 earthquake struck southwestern Puerto Rico on January 7, fast on the heels of a magnitude 5.8 tremor the day before, damaging homes in Guayanilla, Peñuelas, Yauco, and Guánica. ARRL Puerto Rico Section Manager Oscar Resto, KP4RF, told ARRL this week that the situation is relatively “calm and quiet” for now and starting on January 22, volunteers would begin monitoring from their homes or vehicles, permitting most, including Resto himself, to get back to their jobs and homes.
