Available Values: OFF/Values per chart below/1750
Hz
Default: OFF
Use this Menu Item to set the frequency of your en-
coding tone, used for repeater access in the FM “RPT”
mode.
U-38 ( RX-T-F )
Function: Set the desired Tone Decoder frequency
for your receiver
Available Values: OFF/Values per chart below
Default: OFF
Use this Menu Item to set the frequency of your
transceiver’s CTCSS Decoder, if used. The Decoder
is activated by setting this Menu Item to any value
other than OFF, and your receiver will be silent on
FM/RPT until a matching tone is received (superim-
posed on the carrier of an incoming signal).
U-39 ( HF-RPT )
Function: Set the desired repeater shift magnitude
for 29 MHz operation
Available Values: 0.0 ~ 5000.0 kHz
Default: 100.0 kHz
This Menu Item sets the 29 MHz shift separately from
the 50 MHz shift.
U-40 ( VHF-RPT )
Function: Set the desired repeater shift magnitude
for 50 MHz operation
Available Values: 0.0 ~ 5000.0 kHz
Default: 500.0 kHz
The default shift represents the standard value used
in most of the United States.
U-41 ( ANT-SEL )
Function: Define the operating function for the [AN-
TENNA A/B/RX] switch
Available Values: Auto/ on/ oFF
Default: Auto
The available choices are:
Auto The selection of Antenna-A, Antenna-B,
or RX is stored in VFO or Memory regis-
ters, so no operator intervention is needed
when changing bands or memories inso-
far as antenna selection is concerned.
on The [ANTENNA A/B/RX] switch is functional,
but the settings are not stored in VFO or
Memory registers. You must manually
choose the antenna selection yourself.
oFF Only Antenna-A is available. There is no
path provided to Antenna-B nor the RX-
Only antenna.
U-42 ( RTTY-TN )
Function: Select the offset frequency and injection
sideband for the “Mark” tone produced by the inter-
nal RTTY generator
Available Values: Hi 2125U/ Lo 1275U/
Hi 2125L/ Lo 1275L
Default: Hi 2125L
The available choices include:
Hi 2125U The Mark tone is offset 2.125 kHz,
USB injection
Lo 1275U The Mark tone is offset 1.275 kHz,
USB injection
Hi 2125L The Mark tone is offset 2.125 kHz,
LSB injection
Lo 1275L The Mark tone is offset 1.275 kHz,
LSB injection
The Shift tone’s frequency is offset from the Mark
tone by an amount determined by the next Menu Item,
U-43 (RTTY Shift).
U-43 ( RTTY-SH )
Function: Set the desired RTTY Mark-Space fre-
quency shift
Available Values: SFt 170/ SFt 425/ SFt 850
Default: SFt 170
This Menu Item determines the amount of shift to be
applied from the Mark tone frequency, which was pro-
grammed via Menu Item U-42 (RTTY Tones).
