building the tin boxes in the 19inch box

Last night I built the tin boxes in the 19 inch box.
Then it was time to wire them. This took longer than expected. In fact it is still not finished.
To night I will try to finish it.

I build in some relays for switching between receive and transmit.

I had to solve a short circuit. It was quite hard to find. One of the screws made contact with a tin can mounted on the other side.

Next problem will be the power supply. Three voltages are needed 13.8V , 5V and 9.8 Volt.
The 9.8 Volt is for the PA module. This is non standard I suppose The PA module was designed to be fed from Ni cad batteries. I will have to build this power supply myself.
