Pictures of the prototypes. The 9db gain yagi aerial is made from oval plastic electrical conduit using UK 2.5mm twin and earth wire for the elements.
The coax and super mini plugs were from a junk laptop wifi aerial. It's the grey lead on the loop aerial on the 'receive' board.
The pic controller is in the box at the moment with the switch showing, the leds are on board for now. The switch and leds need to be in a desktop box with the pic and the radio module left in the box with the aerial. Nothing is yet sealed, it will be later with a hot glue gun.
I've made the pcb's with a set of pads on the connecting tracks so that the boards can be cut and wire used to connect. They can be just made out on 'receive' board.
The red led on the 'receive' board is a 'heartbeat' led that confirms radio module operating.
The loop is a 3db gain Moxon rectangle.
