I love these little clandestine radios - ingenious solutions in a neat little package.
ReplyDeleteWould love to see some kits based on the Sweetheart & the other radios like the postwar German FE-8 Receiver and the FS-7 Transmitter.
1T4s are in stock at $2.80 at Antique Electronic supply...They have 100 pf variables too.
