I am in the process of integrating the components of a homebrew radio station from stuff I've built in the last few weeks. See the photo below. Click to enlarge.
- On the left is the synthesized Si5153 signal source. It is presently programmed for 40 meters. I'm going to operate the system as a transmitter for awhile then add a receiver. For transmit, I'll add 20 meters to the Si5153 source. When I add a receiver, I'll either give it a separate Si5153 source, or reprogram the existing Si5153 to generate a separate RX source, which can be used for a direct conversion RX or a superhet.
- In the center of the photo is the 10W amp, I put SMA connectors on the input and BNC connectors on the output. Making the SMA jumpers was a big pain in the butt. So was the BNC cable. Once I build up a supply of SMA and BNC jumpers I guess things will get easier.
- The lowpass LC filters on the right. I set them in 3D printed carriers that can be dropped into a larger chassis, which I haven't built yet.
- The remaining components for this project are: 1) TX-RX switch, 2) SWR meter, 3) antenna tuner, and finally, a receiver.
Next I'll be working on the TX-RX switch, then the SWR meter.
