The CDG2000 Antenna Relay Board
This is one of the simpler boards. It is a very simple board that is controlled by the PIC and allows the TX & RX signals from the front end to be switched via an antenna changeover relay to a TX/RX line or via independent TX & RX connectors at low level. It also allows up to 3 transverters to be switched in. It is a tad premature to present this – whilst the prototype works fine, the schematic has not been drawn up yet and the relays are the (old) obsolescent ones. Bit premature but what the heck – here it is..
