Imagine the best DXpedition you could imagine on Earth. You get to be with an elite group of radio amateurs, go on a long journey to get to a rare location on the earth, just to make as many contacts as you can.
Now imagine a remote location and speed. Imagine DXing at over 12,000 miles per hour!
Alas, the Arecibo Radio Telescope [http://www.naic.edu/ao/ ] in Puerto Rico is no longer in operation due to its collapse in December 2020. The 305-meter telescope was in service for 57 years and withstood hurricanes, earthquakes, and tropical storms.
Engineers determined that all three of the telescope’s support towers broke off, sending the 900-ton instrument falling onto the dish below.
NASA has proposed a lunar far-side dipole. The mother of all dipoles is proposed as 20×20 kilometers. Yes, kilometers, about 12.42 miles by 12.42 miles of the lunar surface.
Imagine about 100,000 interlinked dipole antennas in your backyard!
NASA also proposed to build the dipole on-site with lunar materials. A frequency range of 5-40 MHz. The subject for the antenna will be focused initially on the unexplored Cosmic Dark Ages and identifying conditions and processes under which the first stars, galaxies, and accreting black holes formed. No equivalent observatory exists today on Earth.
Set your calendar, get off your couch and go chase or activate a spot on the Appalachian Trail or Park on the Air.
Saturday October 2, 2021 from 12:00-21:00 [ 8AM-5PM Eastern Time ] join operators for Appalachian Trail [ A.T] On the Air Day.
An idea by WB2FUV, Mike, in celebration of the Appalachian National Scenic Trail, licensed amateur radio operators are invited to take their two-way portable radios to the Trail on Saturday, October 2, 2021, for an on-the-air get-together. The goal is to contact other amateur (“ham”) radio operators either along the Trail or elsewhere in North America (or beyond) and to showcase our amateur radio hobby.
Mike wants you to know that, at the moment, this is a spontaneous activity and is not sanctioned or endorsed by any national or regional organization. It is not a contest; it is a get-together.
Our regular club meeting on Sept. 16, 2021 will be via Zoom, and there will be a special video presentation entitled, “RF Exposure and the new FCC Rules.” The presentation is from the ARRL and delivered by Dan Brown, W1DAN and cohosted by Ed Hare, W1RFI.
The Zoom link will be sent out to members before the meeting. The Secretary also sends it to a list of non-members who have asked to attend as guests. If you’d like to receive an email with the Zoom link, please use the contact form on this website and we’ll add you to the list.
During Hurricane Ida, AT&T deployed COWs, but not the type of flying bovines you could imagine. These COWs are known as Cell-on-Wings. The tethered unlimited power drone provides cellular LTE coverage for an area of up to 40 square miles and a further data and voice connection via satellite uplink to AT&T’s network to connect information outside of the affected area. The drones are deployed in a disaster areas to provide a cellular and data bridge to the internet for AT&T’s First Responder “FIRSTNET” network. The drone has been previously tested and deployed by AT&T to other disaster areas, and its design modified over the years to provide additional coverage such as thermal cameras, weather, and wind resistance with the capacity for more sensors. Power is supplied for a continuous flight from the tether and is monitored by an FCC-licensed drone pilot during deployment.
Imagine the possibilities of a tethered drone during your next Field Day operating a vertical on 80, 160, 630, or 2200 meters; or in service to your community for search and rescue operations, supporting triathlons, bicycle races, and more!
