A wonderful project to turn the basic Lima into a full-fledged 10 Watt HF transceiver.
I have been working on this project
with incredible pleasure for a number of years. Before that I had no idea of the
phenomenon SDR, solid digital radio. Besides the pleasure I had, I can say that I have gained a lot of insight into
this matter I have written a report on this in the form of an extensive manual with many images. This guide may encourage
other hams to update the well-known Lima.
With Bernd's excellent basic LIMA-SDR design, DL9WB, I have made some successful CW-QSOs with the 0.5Watt HF output power. Because I thought the power was very low, I went looking for a design with an output power of about 10 Watt. My choice fell ultimately on a clearly defined design by Kurt, with the LIMA-SDR as the basic conc transceiver. I have made a habit of recording my projects' progress in a clear described type of report, manual, or whatever you want to call it, so that I can fall back on that later in case of any modifications. Hereby I have taken over the "red thread" from DJ0ABR and there where useful, supplemented with comments,tips and many explanatory images. This may also enthuse other amateurs to undertake such a project to grab. I learned a lot and had fun while building it. The project is suitable for advanced radio amateurs with some knowledge of electronics.
