Yet Another WSPR Presentation

Here’s a new presentation I gave to the San Juan County Amateur Radio Society: http://wb6cxc.com/?p=86

This has less detail about Raspberry Pi direct frequency synthesis, but more info on other WSPR projects and some newer technology.  Some of this is going to be designed into a drift-buoy I am contemplating, and I discuss some of the related issues, including ham telemetry.
