    HPR4674: Audiobooks

    02/07/2026
    This show has been flagged as Clean by the host.

    Lee recorded a show 4511 which aired on November 17, 2025. Since I had some observations of my own I decided to record a show in response. I have enjoyed some significant series of audiobooks, both in Science Fiction and in History, as they are both topics I greatly enjoy. And many of these are available online.

    HPR4673: First contact conversation

    01/07/2026
    This show has been flagged as Clean by the host.


    Hello, this is your host, Archer72 for another episode of Hacker Public radio.

    In this episode, I make my first contact off a local repeater in a small town in Kentucky.

    What got me to try my hand at radio? It was when I started to capture ISS (International Space Station) Ham radio transmissions. From Kentucky, I have logged receiving from Texas and Oregon and as far as a brief transmission over Great Britain.

    My next step was to have a first contact, which I botched at first when I said my call sign, and didn’t leave enough time for someone to respond.

    I thought that a repeater was the best place to start, so found this one on RepeaterBook.com

    The repeater was found in RepeaterBook at RepeaterBook : My local Cynthiana, Kentucky repeater

    Youtube : Harrison County Amateur Radio Club

    QRZ : Harrison County Amateur Radio Club

    Facebook : Harrison County Amateur Radio Club

    The callsign for this repeater is Kilo-Four-Kilo-Juliett-Quebec

    It is currently On Air (and quite active near club time and the weekend)

    The base frequency is 147.165 MHz with an offset of plus (+) 600 KHz and a tone to open the repeater, of 67.0 Hz

    It is hosted by the Bluegrass Amateur Radio Society

    The RepeaterBook entry was updated on 2025-10-27

    So, with after all that being said I programmed a Baofeng BF-F8HP to this frequency manually. You can also use open source Chirp software, but I wanted to know my radio to program it on the fly.

    This brings me to a recording with permission from Keith (KO4BWJ) who is located outside this little A notable feature of this the town of Cynthiana, Kentucky is the hometown of the artist
    Robert Kirkman for the Television series The Walking Dead, and home to the mural depicting the main characters of the show. This mural had some controversy over the rights to have it depicted, or so I thought. The actual story is story is that some groups did not want a Zombie theme representing their town.

    Without further delay, here is the promised recording.



    I hope you enjoyed and learned from this little piece of an experience Ham vs a new (to the airwaves) Ham.

    HPR4671: Protocal AI

    29/06/2026
    This show has been flagged as Explicit by the host.

    In this episode, Operator dives into his ongoing journey to migrate away from centralized cloud ecosystems specifically moving his daily workflow off Google Keep and onto
    Obsidian
    hosted locally on a Debian server. Operating purely over a secure VPN to minimize his external attack surface, he discusses the security considerations of managing personal data in local plain-text markdown files.

    The episode features a deep dive into local AI infrastructure, sparked by technologist Daniel Miessler’s recent shift away from
    RAG (Retrieval-Augmented Generation)
    in favor of a simpler, localized file-system-as-context approach (using fast search tools like ripgrep). Operator shares his own mixed results experimenting with RAG noting great success with massive, structured car repair manuals, but incredibly poor fidelity when indexing conversational podcast transcripts.

    To find the sweet spot, Operator is testing a
    dual approach
    : combining flat-file local search with a PostgreSQL vector database (
    pgvector
    ). He also rants about the frustrating "hype cycle" of online tutorials that claim to teach "local" setups but secretly rely on expensive, cloud-hosted frontier models.

    Finally, the host introduces his ambitious roadmap for
    "Protocol AI."
    Designed as a localized, read-only dashboard to help manage his ADHD and "time blindness," this system will scrape, aggregate, and summarize his cluttered digital life including multiple Gmail accounts, Yahoo spam, calendars, and a massive array of social media feeds (Signal, Discord, Mastodon, BlueSky). The long-term goal? Transitioning from a read-only local summarizer to a safe, "human-in-the-loop" execution assistant that keeps his data out of the hands of mega-corporations.

    Obsidian is a proprietary personal knowledge base and note-taking application that operates on Markdown files. The software is free for personal and commercial use; only the offered cloud services, optional commercial licenses, and early access versions are paid. It is available as desktop versions for macOS, Windows and Linux as well as for mobile operating systems such as iOS and Android, but not as a web application.

    Obsidian - From Wikipedia, the free encyclopedia

    Retrieval-augmented generation (RAG) is a technique that enables large language models (LLMs) to retrieve and incorporate new information from external data sources. With RAG, LLMs first refer to a specified set of documents, then respond to user queries. These documents supplement information from the LLM's pre-existing training data. This allows LLMs to use domain-specific and/or updated information that is not available in the training data. For example, this enables LLM-based chatbots to access internal company data or generate responses based on authoritative sources.
