Juggled some wires from the receiver I made yesterday to get a transmitter. The video shows me picking up the signal on my G90 (I'm transmitting into a dummy load).
My signal path is going microphone to the input of the first Si5351 (where the antenna was coming in on the receiver). I switched the wires coming out of the Si5351 (so I didn't have to reprogram anything for now), so the ~9MHz is going into the first mixer and the ~5MHz is going into the second (opposite of the receiver).
I'm using this Adafruit board that has an electret microphone and amplifier together. I made a little board that has a blocking cap (22uF - what I had handy) to block the DC bias the board has. In the configuration, it is doing 60db gain and is enough to get 80mv P-P to the dummy load (~ -18dbm). Will probably need to use another amplifier to drive the QRP Labs 10W linear amp.
