Over the last few months Rick KA8BMA has been working steadily on the schematic, PCB, and enclosure CAD work for the SM1000 Beta. This is now complete, the Beta PCBs have been made, and the first 2 Beta units are being hand assembled by Edwin at Dragino. Rick and I will test these, then kick off the Qty 100 Beta run which I estimate will be on sale in January.
I’m a bit intimidated by the mechanical CAD work required to make an enclosure, but Rick has stepped right up and done a fine job designing a bent metal case comprised of two U-shaped halves. This can be economically made in small quantities. This sort of case is more suited to the “small box on the desk” form factor, but that’s OK for now. It still has an aperture for the internal microphone. Click for larger images.
Last week I visited VK2 and gave a talk at the ARNSW Home Brew Group meeting at Dural, on the NW edge of Sydney. I had a very pleasant day with Peter Marx who was kind enough to drive me there and record the talk. As well as the standard intro to Codec 2 and FreeDV the second half covers the SM1000.
