I recently changed my default zap from 21 sats to 73 sats. '73' has a meaning in ham radio that is rooted in tradition and history. It's not just a number — it's a time-honored way of saying 'Best Regards.' Originating from early telegraphy, this shorthand has been used by radio operators for over a century to sign off with warmth and goodwill. So, next time you hear '73,' or get zapped 73 sats remember, it's more than a farewell — it's a friendly wish for the best. If you haven’t been zapped 73 sats by me yet, post some radio comment. It will help me find it if you use some radio related hashtags. You might even get zapped for bringing radio content to my attention by replying to it with @HR4BTC aka HamRadio4Bitcoin . #HamRadio #AmateurRadio #73 #radio #morsecode #cw #telegraphy #bestregards #highlyregarded

Antenna Basics: Vertical or Horizontal etc Vertical antennas are great for omnidirectional coverage and require less space—perfect for limited environments. Horizontal antennas offer directionality and less noise, making them ideal for focused communication. Your choice depends on your specific needs and space. @HR4BTC aka HamRadio4Bitcoin recommends following KE0OG on YouTub. He is literally an “OG” ham radio educator that has a very large catalog of quality ham radio educational materials. #HamRadio #AntennaBasics #RadioCommunications #hf #antenna #dipole #davecasler #davidcasler #ke0og #og #radio #amateurradio #radial

Just get one where you are & learn along the way. If you still feel like you need a different one after you learn more, you will know where to go next. View quoted note →

What is an MMDVM Hotspot? MMDVM stands for "Multi-Mode Digital Voice Modem." An MMDVM hotspot is a small, low-power radio device that enables amateur radio operators (hams) to connect to various digital voice networks using the internet. These hotspots are designed to work with a variety of digital modes, such as DMR (Digital Mobile Radio), D-Star, System Fusion (YSF), P25, NXDN, POCSAG and the new FOSS M17 Project digital mode. The hotspot acts as a bridge between a ham radio and the internet. When you talk into your radio, the hotspot receives the signal, converts it into a digital format (if necessary), and transmits it over the internet to a linked repeater, reflector, or other digital radio network. This allows you to communicate with other hams globally, even if you're only using a low-power handheld radio. The digital ham radio modes are interesting when connected via internet because of they allow the use to connect to specific voice chat rooms that are called various names depending on the digital mode. They are called “talk groups” in DMR, “reflectors” in D-Star and rooms in YSF. These groups can be regional or topic based and etc. Folks with skills running servers can even start their own talk groups rooms and reflectors (hint hint, look into it).👀 Common Components of an MMDVM Hotspot 1. Raspberry Pi: The most common computer used for an MMDVM hotspot is the Raspberry Pi, typically a Raspberry Pi Zero or Raspberry Pi 3. These are small, low-cost, single-board computers. 2. MMDVM Hat with antenna: This is the radio module that attaches to the Raspberry Pi. It contains the necessary circuitry to handle the digital modes and interfaces with the Raspberry Pi through GPIO pins. 3. Case: optional Cost and Ease of Building: aka You really should build your own. - Cost: Depending on the components you choose, the total cost of an MMDVM hotspot typically ranges from $50 to $100, making it a very affordable project for amateur radio enthusiasts. - Ease of Build: The project is relatively simple and requires basic skills in assembling electronics and setting up software. The most challenging part is configuring the software, but numerous online resources and communities are available to help, there are great YouTube videos on this. You can even save a few bucks (fiat) if you have basic soldering skills. Overall, MMDVM hotspots provide an excellent entry point into the world of digital amateur radio communication at a low cost and with relative ease. #mmdvm #ham #hamradio #radio #amateurradio #hotspot #pi #pizero #p25 #m17 #ysf #dstar #drats #dmr #nxdm #pocsag #pager #wspd #pistar #project #network #gpio #solder #pihat #wpsd

DYK: The Solar Cycle (☀️🚴‍♂️) has a huge impact on HF radio propagation. This cycle is looking to be one of best cycles for propagation in decades and we are going to soon be entering the peak of the cycle. If you were on the fence about getting your ham radio license or upgrading your license to do HF, perhaps this will provide you some FOMO to get on it now. Digging Deeper: The solar cycle is an approximately 11-year cycle in which the Sun's magnetic activity fluctuates, causing variations in solar phenomena like sunspots, solar flares, and coronal mass ejections (CMEs). During the solar maximum, the Sun is most active, with a higher number of sunspots and solar flares. In contrast, the solar minimum features fewer sunspots and reduced solar activity. The impact on radio communications, especially in the high-frequency (HF) range (3 to 30 MHz), is significant. During the solar maximum, increased solar activity enhances the ionosphere's ability to reflect HF radio waves, improving long-distance communication. However, solar flares and CMEs can cause sudden ionospheric disturbances, leading to radio blackouts and disruptions in navigation and communication systems. Conversely, during the solar minimum, while there are fewer disruptions, the ionosphere's reduced ionization can limit long-distance HF radio propagation.

🌎🌖🌍📻 Earth-Moon-Earth (EME) Radio aka Moonbounce is Inspiring Electronic Musicians to Create New Music Delay Effects. Radio signals can be bounced off of the surface of the moon in a process called “moonbounce”. This technique has been in use since the WWII and is still practiced today by radio amateurs. Although radio waves move at the speed of light, the moon is far enough away that there is a delay for the radio signal to get to the moon and return back to earth. There are other properties of the moon surface and radio waves that also impact the signal on the received end. This effect is now being used to create new musical delay effects such as the one in this video, “Echos from the Moon”. On a moonbounce radio & bitcoin tangent: "...I believe every nation should commit itself to achieving the goal, before this decade is out, of bouncing a bitcoin transaction off the Moon and returning it safely to the mempools of Earth.” ~made up historic quote circa 2024 #eme #earthmoonearth #2themoon #ham #hamradio #amateurradio #rf #wwii #moonbounce #emecomms #music #musicstr #edm @bitpunk.fm is typing

@Bitcoin.Review Radio Recap aka The BRRR by @HR4BTC aka HamRadio4Bitcoin In BR072, @DETERMINISTIC OPTIMISM 🌞 and guests @Paul @Rob Hamilton & @npub1mxrs...0htc discuss a variety of radio topics. During the intro segment, NVK calls on bitcoiners to go out and get a ham radio license. In the main segment, they cover the new releases for Reticulum and RNS. They cover the open source M17 Project digital radio mode release updates and they close on wanting to do a full panel with ham radio bitcoiners and lament the lack of ham radio nerds in bitcoin. NVK summed up the radio topics with “radio is magic”. 📻⚡️=🧙‍♂️ Timestamp 1 0:03:45-0:04:00 Timestamp 2 1:24:48-1:30:09 #Reticulum #RNS #NomadNet #mesh #lora #m17 #hf #uhf #vhf #packet #data #rf #radio #amateurradio #hamradio #brrr #TheBRRR #BitcoinReviewRadioRecap #Bitcoin.ReviewRadioRecap

⚡️ 🚙 📡 Radio direction finding made very easy for less than $1000 in fiat.📡🚙⚡️ Check this out and think about what is currently possible with low cost civilian radio direction finding. This technology will only get cheaper and more features over time. Definitely check out KrankenRF’s github too. Link in thread. DYK: In ham radio, there is a sub-community or sub-hobby within the hobby interested in rf direction finding. These folks put on “fox hunting” events where teams compete to find a hidden transmitter (aka “the fox” 🦊 ). Even with technology like this, it may not be as easy as you think because of other factors that can come into play that you will learn about as you go further down the radio rabbit hole. 🐇🕳️ #KrackenRF #KrackenSDR #radio #rf #sdr #directionfinding #foxhunt #foxhunting #ham #hamradio #radio #amateurradio #mesh #meshtastic #softwaredefinedradio #releasethekracken #kracken
