Portsdown Construction

Post by G4KLB » Thu Sep 14, 2017 12:10 am

Congratulations to the worthy winners of the Portsdown construction competition at CAT 17.
If anyone took any photos of the entrants, please post them here.
Even if you didn't enter, post them here as well, we would love to have a look at them :-)

I will start the ball rolling with my effort.

A picture of the G4FRE build.
I wanted some screening, hence the metal chassis and panels in the plastic box.
I used two smps power units; one set to 5,2V for the RPI and output rf switch and one set to 8V for the DDS, Lo filter and FM. I have left space for more modules e.g. the programmable attenuator and a custom amplifier switch/controller

After having issues with supplying power to the RPI through the microusb connector I soldered power leads directly to the board. This fixed the issue
