Richard, G3NII started by explaining how the circuit worked and why certian components were used. He also explained why minor modifications were being introduced. Ian, G3ORG followed by drawing a block diagram to show how areas worked with others. Ian also had a test set up to demonstrate the effectivness of the project. Members then submitted their projects to be checked.
Paul, G1GSN who supplied the close up photos of the board says: The picture of the standing resistor is the new one – changed from 100 ohms to 33 ohms. Instead of mounting on the output (awkward), the resistor stands in the redundant hole of the noise switch. That moves just a little bit inboard and makes space away from PTT input and the 12V supply. I thought it would be a good idea to show where the new C18(100pF) fits across the resistor R1(1k), hence the view of the solder side of the PCB.
