The rush to claim vanity geohashes in bitchat has officially begun. For example, there are opportunities to claim territory in the arctic for rooms that begin #BTC. Claim a territory by posting a message in it and replying to this thread with your vanity #bitchat #geotag. I claim geotag #HR4BTC. We may have to do a group chat in there sometime soon. Search engine for available vanity geotags:

🤣 The Bugle is right, Emissions Control (EMCON) is a very important concept. Also, it is a good idea to get all of the Bitcoin wives licensed in ham radio. #hamradio #gmrs #amateurradio View quoted note →

Local Emergency Communications with NVIS - Let's Build an 80m/40m Dipole By The Tech Prepper “In this video, we'll take a look at building a simple 40m and 80m dipole for $20 dollars. Then, we'll deploy it in an NVIS (Near Vertical Incidence Skywave) configuration for local and regional communications.” NVIS, or Near Vertical Incident Skywave, is a method of radio communication that uses shortwave frequencies to achieve effective local and regional communication. This is particularly useful in areas where line-of-sight communication is hindered by obstacles like mountains or buildings. 1. High Angle Radiation: NVIS antennas emit radio waves at high angles, typically between 75 to 90 degrees. This allows the signals to reach the ionosphere quickly and reflect back to the Earth's surface. 2. Short to Medium Range Communication: By reflecting off the ionosphere, NVIS covers a range typically from 30 to 400 miles, bridging the gap between line-of-sight VHF/UHF communication and longer-range HF skywave communication. 3. Antenna Types: Common NVIS antennas include simple dipoles, inverted V antennas, or loop antennas, often positioned only a few feet above the ground or on rooftops. 4. Ionospheric Dependence: The effectiveness of NVIS depends on the current state of the ionosphere, which is influenced by solar radiation and time of day. It's most effective at frequencies between 1.8 MHz and 10 MHz. 5. Applications: NVIS is widely used in military, emergency services, and amateur radio operations, especially in rugged terrain or during natural disasters when traditional communication methods are disrupted. This method offers reliable, consistent coverage over a specified area, making it a vital tool in various communication scenarios. #hamradio #amateurradio #nvis #ttp #prepper #emcomms
