Sunday night breadboard

Tonight I worked on laying out breadboard for the QRSS rig while talking on Echolink on the QRP conference.

I had wanted to etch a board but the last couple of days have been pretty busy. Tonight was the first time that I have actually played with the radios (outside of skywarn) or visited my electrical workbench for an RF project.

I decided to lay out the oscillator + PA + lowpass filter so that I could validate the combined design and then focus on using the PIC 16F628 for PWM (pulse width modulation) with a LED acting as a varactor diode. I finished the oscillator + 1/2 of the PA. It was fun to get back to the work bench for a little while.
