A simple DIY project for a remote cw key connected to your Flex Rig (actually it can be any other rig). On the remote side it uses and Arduino Uno board and a cheap HanRun Enc28J60 ethernet shield. On the local side it uses a key (better a keyer) connected to a serial port of your pc. Probably you need also to use a USB to RS232 adapter to connect it to new generation computers. You don't need to have an active computer on the remote side, just your router, the Flex and the Arduino board.
