| === Software ===
| |
| * Sending test payload --> '''works!'''
| |
| * Sending data from rtl_tcp on RasPi over the network --> '''works!''' (1024000 samples/second seems to go fine when both are on a wired connection)
| |
| * gqrx to listen to audio --> '''works!'''
| |
| * dl-fldigi RTTY decoding --> '''works!'''
| |
| * Testing VNC performance with gqrx and dl-fldigi --> '''usable with JPEG compression and 8 bits of color'''
| |
| '''Todo'''
| |
| * Setting up a virtual machine with gqrx and dl-fldigi

| == Todo ==
| |
| | |
| * Site survey roof, check if there is already some sort of lightning protection system, and see if we can add some metal construction to it ourselfs
| |
| * Currently we have no antenna. Well need some heavy duty (directional?) antenna.
| |
| ** Do we make one or do we buy one?
| |
| ** What kind of antenna? (keep in mind we only have line of sight towards south/southwest)
| |
| * Find and buy IP56 enclosure
| |
| * Routing Ethernet (with PoE) towards the roof, possibly using (something like) this: http://www.ebay.co.uk/itm/200841109556
| |
| * Your ideas, we love them!
