So I saw DX Explorers video about the 10minute transmitter, so I built it with parts found around the bench. The design I saw was Sunrise net special by Walter KA4KXX http://soldersmoke.blogspot.com/2020/... This in turn is apparently based on the “Ten Minute Transmitter” by G4RAW (SK), which apparently first appeared in SPRAT 82 in 1996. DX Explorers video on this transmitter: • Video You can follow me on Twitter: / 2ftg1 Or read my website at: https://sites.google.com/site/oh2ftg/ Or sometimes catch me on IRC as: ftg on Libera.Chat and IRCnet
