This from “rwr01″ on the radiokits Yahoo Group:
I came across the Kit Radio Company the other day. They advertise some nice professional looking radio kits. They offer a Superhet, a Regenerative, a TRF and a DC receiver (all transistorized) and a couple of (looks like VXO) transmitters too! They’re based in England but shipping overseas doesn’t add much to the cost as they simply don’t include batteries when they ship overseas.
Their KRC-2 Shortwave Regenerative Receiver is reminiscent of the Science Fair Globe Patrol featured on this group’s main page. Looks like it might have resistive rather than capacity feedback though as it says regeneration is unaffected by receiver tuning or antenna coupling.
