pics-Solid State QRP Rig

Pete Juliano, N6QW,  built his own vintage 1955 Solid State QRP Transmitter using the Philco SB-100:

Recently my friend Bill, N2CQR posted data on his blog ~ soldersmoke.blogspot.com about a vintage late 1950’s early 1960’s 10 milliwatt 10 Meter transmitter. That was quite a feat!
But given my Italian heritage I could not let that pass without building my own solid state transmitter using a transistor from 1955. My rig operates on 14.060 and produces 0.4 milliwatts with a 3 volt collector supply using a Germanium transistor from Philco. The SB-100 was one of the first RF transistors that could work all the way past the 10 Meter band. The max Pout was 10 milliwatts –so mine is just loafing along.

More details at N6QW Homebrew Radio blog.

Check out the video after the break.
