Because the hobby is rooted in experimentation and &#8220;homebrewing,&#8221; many of the most popular projects are designed specifically to be built, modified, and repaired by operators at their own workbenches. Here are some of the most prominent open hardware projects across the hobby right now:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">HF Transceivers &amp; SDRs<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The BITX Family (<a href=\"https:\/\/github.com\/afarhan\/sbitx\" type=\"link\" id=\"https:\/\/github.com\/afarhan\/sbitx\">sBITX<\/a>, <a href=\"https:\/\/github.com\/afarhan\/ubitxv6\" type=\"link\" id=\"https:\/\/github.com\/afarhan\/ubitxv6\">uBITX<\/a>, <a href=\"https:\/\/github.com\/vu3sua\/EasyBitx_v1.3\/blob\/main\/EasyBitx_v1.3.ino\" type=\"link\" id=\"https:\/\/github.com\/vu3sua\/EasyBitx_v1.3\/blob\/main\/EasyBitx_v1.3.ino\">Easy BITX<\/a>):<\/strong> Designed by VU2ESE, these transceivers are legendary in the homebrew community. The <strong>uBITX<\/strong> and <strong>Easy BITX<\/strong> provides a highly accessible, hackable analog platform perfect for learning alignment and troubleshooting. Meanwhile, the newer <strong>sBITX<\/strong> is a Software Defined Radio (SDR) that integrates a Raspberry Pi directly into the radio for digital modes and DSP.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/pa3gsb\/Radioberry-2.x\" type=\"link\" id=\"https:\/\/github.com\/pa3gsb\/Radioberry-2.x\">Radioberry<\/a>:<\/strong> An open-hardware radio card (HAT) that plugs directly into the GPIO pins of a Raspberry Pi (like a Pi 4 or Pi 5). It uses an AD9866 broadband modem chip to turn the Pi into a standalone SDR transceiver. It is highly popular for remote operation and digital modes.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/softerhardware\/hermes-lite2\" type=\"link\" id=\"https:\/\/github.com\/softerhardware\/hermes-lite2\">Hermes-Lite 2<\/a>:<\/strong> A completely open-source hardware, low-cost direct down\/up conversion SDR HF transceiver. It utilizes a Gigabit Ethernet interface rather than USB, making it an incredibly robust choice for networked station setups.<\/li>\n\n\n\n<li><strong>mcHF:<\/strong> Designed by <a href=\"https:\/\/github.com\/m0nka\/mcHF\" type=\"link\" id=\"https:\/\/github.com\/m0nka\/mcHF\">M0NKA<\/a>, this is a compact, standalone SDR QRP (low power) transceiver. It features a built-in display and DSP, meaning it operates entirely without needing to be tethered to a PC.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Station Accessories<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/github.com\/k3ng\/k3ng_cw_keyer\" type=\"link\" id=\"https:\/\/github.com\/k3ng\/k3ng_cw_keyer\">K3NG Arduino CW Keyer<\/a>:<\/strong> One of the most comprehensive open-source hardware and software projects for CW (Morse code) operators. It supports WinKeyer emulation, message memories, LCD displays, and can be customized to fit almost any physical enclosure.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/skuep\/AIOC\" type=\"link\" id=\"https:\/\/github.com\/skuep\/AIOC\">AIOC (All-In-One-Cable)<\/a>:<\/strong> A tiny, open-source hardware USB-C dongle that acts as a soundcard, PTT controller, and programming cable for popular analog handheld transceivers, allowing them to easily interface with digital packet software.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Digital Voice &amp; VHF\/UHF<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/github.com\/m17-project\" type=\"link\" id=\"https:\/\/github.com\/m17-project\">M17 Project <\/a>(OpenHT &amp; Module17):<\/strong> M17 is a completely open-source digital radio protocol designed to replace proprietary, patent-encumbered systems. The project team produces open hardware like the <strong>OpenHT<\/strong> (an open SDR handheld transceiver) and <strong>Module17<\/strong> (a modem to retrofit existing 9600-baud analog radios for M17).<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/VanceVagell\/kv4p-ht\" type=\"link\" id=\"https:\/\/github.com\/VanceVagell\/kv4p-ht\">kv4p HT<\/a>:<\/strong> An innovative open-source hardware project that consists of a custom RF module that plugs into an Android phone via USB-C, turning the smartphone into a modern, fully functional VHF\/UHF ham radio transceiver with a touchscreen interface.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Amateur radio has a massive and highly active open-source hardware community.
