Kantronics
Phil Anderson, W0XI was mentioned previously here: https://wb9kzy.blogspot.com/2023/07/phil-anderson-w0xi-sk.html I saw this Kantronics QRP transmitter on Face: It's an interesting design - the thing I noticed was the classic mechanical design of a Bakelite box plus a top plate. Another interesting detail, the key was connected between the positive power and the rig - this is similar to the original Tuna Tin 2 transmitter. But instead of another transistor the Rockhound uses a CMOS hex inverter chip as both the crystal oscillator and the driver of the VN66 output MOSFET. I wonder how it sounds ? Probably depends on the crystal, antenna, supply, blah blah blah :) I imagine that the Rockhound might have been paired with the Kantronics 8040 receiver, manual here: https://www.manualslib.com/download/3124657/Kantronics-8040-B.html The 8040B was a FET heavy design. Here is an ad from the May 1980 issue of 73 Magazine for the Rockhound, the 8040B and the Freedom VFO: An...
