Our mission is to bring Bitcoin Plebs & Devs into ham radio in order to help the bitcoin community to achieve technical proficiency in radio communication techniques so that they will be able to contribute to advancing the radio arts in alignment with the ethos of Bitcoin. ⚡️⚡️⚡️Let me know if there is ham radio content that you would like to see me repost. I will see it if you use #hamradio or @HR4BTC it in a reply. ⚡️⚡️⚡️

This interview from 03/16/2024 is a recap of some of latest tech & software developments in Ham Radio.

Radio is a decentralized freedom technology. It is worthwhile as Bitcoiners and Nostriches to learn about radio and keep up on developments that may have practical applications for us. There are so many new opportunities in this space, many haven’t even been thought of yet.

To my knowledge neither of these two have expressed an opinion on Bitcoin or Nostr. With that being said, they are great resources for radio information and I would recommend following both of them if you use platforms they are on for information about radio.

73 in ham radio:

73 is a code that means "best regards" or "best wishes." It's used at the end of a communication to signal a friendly farewell. The term comes from the Phillips Code, a shorthand numerical code developed in the 19th century for telegraphic communications. "73" has been adopted by amateur radio operators worldwide as a traditional sign-off.

Many abbreviations you may be familiar with today originated in the Philips Code.

Breaking Ham Radio News:

APRS just got a new feature, you can now use a store and forward message service on APRS.

What is APRS?

APRS stands for Automatic Packet Reporting System, a digital communications system that uses packet radio technology to transmit small packets of data over amateur radio frequencies. Its primary purpose is to share real-time information, usually pertaining to location, but it can also carry text messages, weather reports, and telemetry data. APRS is used by amateur radio operators to track positions, for emergency communications, for weather balloon data, and for various other applications where quick and precise information sharing is necessary. It operates mainly on a single VHF frequency (144.390 MHz in North America) and can be interfaced with GPS units to broadcast an individual or object's location, making it a valuable tool for search and rescue operations and mobile tracking.

Interesting, there is a new NES game with a ham radio angle.

Anyone play this yet? Does anyone have a review?

Thanks nostr:npub1dqg3at6cmahs4fqlu027lllkm942h90hyvgsuxqqe9pg4p09sn0szs3643 for the heads up.

There are people doing interesting things in radio that haven’t found Nostr yet. This is one of them I recommend checking out.

In the United States, a vanity call sign is a specific type of call sign that amateur radio operators can choose, rather than being assigned a call sign at random by the Federal Communications Commission (FCC). These call signs are chosen by the operators themselves and usually reflect their personal preferences, interests, or identity. The FCC established the vanity call sign program to allow for this personalization while still ensuring that all call signs adhere to the FCC's regulations and formats.

Competition and Waiting Period: For highly desired call signs, there might be competition among several applicants. The FCC uses a randomized process to assign the call sign in such cases. There may also be a waiting period before a recently available or unassigned call sign can be applied for as a vanity call sign.

Here are the general formats:

• 1-by-2 Call Signs: These call signs have a single letter prefix, one numeral for the region, and a two-letter suffix (e.g., K6AB).

• 2-by-1 Call Signs: These call signs have a two-letter prefix, one numeral for the region, and a single-letter suffix (e.g., AB6C).

• 1-by-3 Call Signs: These call signs have a single letter prefix, one numeral for the region, and a three-letter suffix (e.g., K6XYZ).

• 2-by-2 Call Signs: These call signs have a two-letter prefix, one numeral for the region, and a two-letter suffix (e.g., AB6CD).

• 2-by-3 Call Signs: These are also used, typically for General and Technician class licenses, with a format such as (e.g., AB6XYZ).

The prefixes “K”, “N”, “W”, and “A” are commonly used in the United States. “AL”, “KL”, “NL”, “WL” are typically reserved for Alaska; “KP”, “NP”, “WP” for Pacific territories; and “KH”, “NH”, “WH” for other Pacific territories, including Hawaii.

Vanity call signs allow amateur radio operators to have a more personal and memorable identifier in the amateur radio community. They are a popular option for those who are deeply involved in the hobby and wish to express their individuality or commemorate something special through their call sign.

What would be some good Bitcoiner or Nostrich vanity callsigns?
