Sixbox QRP rig for 6m

Sixbox 6m AM rig – a simple design

Several years ago I designed and built a derivative of my 2m Fredbox but for 6m AM. The same basic design would easily translate to a 10m version.  Both bands could be useful for cross-town natters, especially when both 10m and 6m behave like VHF bands, which is in the quieter sun years and at night on 10m. The Sixbox is simple and certainly capable of further development.

Treat the design as a starting point. A 10m version of the RX has copied transatlantic USA AM stations well, but this is NOT a rig for DX use. It is better suited to cross-town/inter-village natters.
