Operation on 5 MHz Band
(
U.S. Version Only
)
The FT-818 includes the capability for transmission and reception on the ve spot frequen-
cies assigned to the Amateur Service in the United States. To operate on the 5 MHz band:
1. Press the key once to enter the “Memory”
mode (a memory channel number “M-nnn” will
appear on the display in the space previously
occupied by “VFOa” or “VFOb”).
2. Rotate the
knob to select the desired
channel (“M-601” through “M-605”), at the facto-
ry, with the permitted frequencies in the 5 MHz
band.
If you have partitioned your memory channels into Memory
Groups via Menu #34, the memory channel numbers for
60-meter operation will be displayed as “l - 001” ~ “l-005”. See
page 42 for details regarding Memory Group operation, and
page 59 for details regarding Menu #34.
3. Pressing the
or key momentarily, switch-
es the operating mode between SSB and CW.
4. To exit from 60-meter operatin and return to the VFO mode,
just press the
key (the memory channel number will be
replaced by “VFOa” or “VFOb”).
The frequencies and operating mode for 5 MHz band opera-
tion are both xed, and may not be changed.
PSK Operation on 5 MHz Band
1. Press the
key once, if necessary, to enter the “Memory” mode.
2. Rotate the
knob to select the desired channel (“M-601” through “M-605”),
at the factory, with the permitted frequencies in the 5 MHz band.
3. Press the
or key to select the SSB mode.
4. When the “transmit” command is received from the TNC, the FT-818 transmitter
will be engaged. The microphone input is disabled automatically when transmit-
ting the PSK signal.
Likewise, the TNC “receive” command will cause the radio to revert to the re-
ceive mode.
You can adjust DATA input level using Menu #25 [DIG MIC].
During PSK operation via the rear panel DATA jack, the front panel MIC
jack is cut off, so you won’t have a “live microphone” problem during data
operation.
Set the PSK sub carrier frequency of the TNC to 1.5 kHz.
