Satellite Operation - Yaesu FT-847 Operating Manual

OPERATION
The FT-847 is an outstanding performer on amateur satellites, providing "turn-key" operation on Voice/CW "ana-
log" satellites, and easy interface for digital mode operation.
The chief features of the FT-847 for satellite operation include:
l Full duplex crossband capability, pioneered on the Yaesu FT-726R;
l Uplink/downlink "tracking" of the VFOs, introduced on the Yaesu FT-736R;
l Dual frequency displays, showing both uplink and downlink frequencies;
l The SUB-TUNE control, which allows manual adjustment of the uplink frequency;
l The dedicated Satellite "Memory" VFO system, which includes alpha-numeric labeling of the memories
and independent operating mode storage on the uplink and downlink registers; and
l The frequency entry keyboard (including the [SUB] key), which makes loading of uplink and downlink
frequencies simple.
Satellite operation involves transmission on one band while simultaneously receiving on another band (sometimes
on another operating mode, as well). This is different from "Split" operation, where transmission and reception are
not occurring simultaneously; the [SPLIT] key should not be used during satellite operation.
