How I do it! A complete POTA activation from start to finish - KB9VBR Antennas
Watch me, in real time, as I deploy an end fed half wave antenna, set up my station on a picnic table, and do a QRP (5 watt) POTA activation on the 15 meter band.

Examples of distant galaxies being gravitationally lensed by Abell 2744, causing them to appear 3 times from our perspective.
arxiv.org/abs/2403.070...
🔭 🧪
Examples of Gold, Silver, and Bronze systems shown in an RGB image made of F200W, F150W, and F115W filters. Top: System 6 is a Gold system - it has 3 images with well-determined redshifts and the colors and morphology of the images make it clear that they are the same galaxy. Middle: System 23 is a Silver system; there are 2 knots visible in some images but not the others and the colors of the images appear slightly different. The Ly-alpha emission that determines its redshift is much stronger in the first image than the other two. This may be a true system, but because of these factors, we are not confident enough to include it in the Gold category. Bottom: System 32 is a Bronze system; while these images all show Ly-alpha emission at the same redshift in the MUSE data, the images are very faint and the colours appear somewhat different. The third image (right) is an example of a Quartz image - there is no source seen here in the NIRCAM data. This system is included in the catalogue f

Full MIRI image of a region parallel to the massive protostar known as IRAS23385.
🔭 🧪
A region of a molecular cloud. The cloud is dense and bright close to the top of the image, like rolling clouds, and grows darker and more wispy towards the bottom and in the top corner. One bright star, and several dimmer stars, are visible as light spots among the clouds. The image is a single exposure which has been assigned an orange colour for visibility.

Nevada’s action would “make it easier for criminals to access the communications of children because if you make it easy for law enforcement to access, you make it easier for criminals to access too" — a really bad trade-off, EFF’s Cindy Cohn told Las Vegas' KLAS 8 News Now.
