1) 6-Digit Numeric Display Readout -
This display
indicates frequency, in ‘MHz’, for the ‘A’ transceiver’s
current VFO, Priority, or Memory channel. Frequencies
from 144.000 to 148.000 MHz will be displayed*.
2) 7-Digit Numeric Display Readout -
This display
indicates frequency, in ‘MHz’, for the ‘B’ receiver’s
current VFO, Priority, or Memory channel. Frequencies
from 136.0000 to 174.0000 MHz, or from 420.0000 to
470.0000 MHz will be displayed.
3) VFO 1/VFO 2 -
Indicates the selected VFO for
transceiver ‘A’.
4)

5) VFO 1/VFO 2 -
Indicates the selected VFO for
receiver ‘B’.
6)
/PW/MEM/
/
for Receiver ‘B’ -
Same functions

and the relative signal strength. Item 7 refers to Trans-
ceiver ‘A’; Item 8 refers to Receiver ‘B’.
9) TNC STATUS Indicators (for optional TNC270 use) -
XMT - TNC is in the transmit state.
DCD - Data Carrier Detect indicates that a valid data

receiver 'B' are configured for the Satellite mode of
operation.
13) WXSAT -
Lights to indicate that the receiver 'B' is
configured for the weather satellite mode of operation.
14) DATA/VOICE/Indicators -
Separate indicators for
Transceiver ‘A’ and Receiver ‘B’.
DATA - Unit is in the DATA mode which permits TNC
communications. When ‘A’ is in the DATA mode, TNC
audio is sent to the transmitter and the front panel MIC
input is disabled.
VOICE - Unit operates as a normal audio transceiver
(‘A’) or receiver (‘B’). The front panel MIC input is
active when ‘A’ is in the VOICE mode.
A STANDBY mode is indicated as follows:
Transceiver ‘A’ - ‘DATA’, ‘VOICE’, ‘SAT’ and the fre-
