The Knobless Wonder (simple SSB transceiver)
This rig breaks one of my slogans for hombrew gear: "Frequency agility is king". Still, especially if you've got a book to read between CQ calls, operating can be a fun. And you'll get a kick out of making contacts with a rig you built yourself.
The Knobless Wonder is a single frequency crystal controlled SSB transceiver. The fortunate availability of 7 MHz band crystals means that you can do the SSB filtering on your operating frequency. This simplifies circuitry as there's fewer frequency conversions involved. And quite a few people around the world have built it.
Interested? Visit my Knobless Wonder Page for more of a description, videos and links to others who have built it.
