Simple 10m rigs

As 10m slides to the “quieter years” of the solar cycle it will soon be time to look again at using this band for local communications. It makes an ideal band to natter across town and I still think a 10m Fredbox is worth a go. The receiver, a simple super-regen is extremely simple, very sensitive with a simple RF amplifier, but lacking in selectivity so would NOT be useful when the band is busy. At night time in the quieter years it would be perfectly fine. The alternative is a simple 10m DSB rig, which would  be compatible with SSB transceivers.

At the moment, my poor health is stopping me doing both of these projects.
