The idea is to use AUI Ethernet adapters on very high amateur radio frequencies (10 GHz): AUI adapters provide 10 MBit/s transmission speed and could thus be used to implement high volume radio data networks. Especially interesting would be to connect both ATV relays DB0MHB and the relay in Parsberg digitally. Here's some information relevant in the context of this idea:
- Ethernet AUI Port, Pinouts, and Cable Specifications
- Attachment Unit Interface
- IEEE 802.3 10Base2, IEEE 802.3 10Base5
