10 MBit Amateur Radio Data Link: Unterschied zwischen den Versionen

Version vom 7. Januar 2009, 01:36 Uhr

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
• An Experimental 10-Mbit/s Microwave Data Link

2  control in circuit A            collision +ve
3  data out circuit A              transmit data +ve
4  data in circuit shield          ground
