I recently saw a K1 in good condition that had two bandmodules (80/40 and 40/20)
and a built-in ATU and was sold for 170 USD.
I was stupid enough not to buy it.

Hi QRP,

Yes that the circuit!

I'm only going by this blog: http://www.radiohobbyist.org/blog/?p=271

It stated channel Z "First up, he used a Corsette transmitter, putting out 1.1 watts" - it doesn't say on Dave Martins website what output power it is just QRP!


Dave Martin launched his Corsette transmitter already in June 2009 with the same design but Chris Smolinski wrote about it first in December 2011 in "RadioHobbyist.org".
