Footnotes: (1) In North America the following frequencies are suggested for Packet digipeater and packet scatter operation:
50.62/51.62 50.68/51.68 50.76/51.76 50.64/51.64 50.72/51.72 50.78/51.78 50.66/51.66 50.74/51.74
For co-located voice and packet repeaters, use high (input) and low (output) to provide maximum mutual frequency isolation. (2) Table of Repeater Pairs. (3) Amateurs are requested to avoid using FM or other wide band modes on these frequencies to minimize interference to Australian and New Zealand Amateurs working into Region 2 on SSB/CW. (4) North American Amateurs are requested to avoid calling “CQ DX” on 50.110 MHz. |
