SDR Software defined radio kits, genesis SDR kits

The SDR-908 is a software defined radio designed specifically for portable use, without the bother of being tethered to a PC or soundcard for the modulation/demodulation processing performed in this kind of radio.

Details on projects by WA3TFS published in QST magazine over the past few years. Includes an online shop with several ham radio kits, circuit boards, simple SDR transceivers

The MiniPA Linear Amplifier for HF page discusses the popularity of QRP for HF among ham radio operators, such as those using the Yaesu FT818 or low power SDR transceivers. It explores the use of cheap kits from eBay or Chinese suppliers to build a 70-100W SSB amplifier using IRF530 MOSFET transistors. The article provides a review of the MiniPA design, including its features, components, and assembly process. It also highlights the importance of using a heatsink and forced air cooling for optimal performance. This page is useful for hams looking to enhance their HF rig with a budget-friendly amplifier.

The T41-EP SDT is an open-source software defined transceiver designed by Albert F Peter (AC8GY) and Dr. Jack Purdum (W8TEE) with contributions from others. This detailed guide covers the design, theory, and assembly of the transceiver, making it suitable for both beginners and experts in SDR. Learn about Digital Signal Processing and how it is implemented in the T41-EP, as well as the modularity of its internal design. Kits are available for easy assembly, and a supportive community on SoftwareControlledHamRadio Groups.io provides additional resources for users. Note that software support for additional bands is in progress, offering potential future upgrades.
