SETTING UP ORION FOR AM TRANSMIT

The same factors that affect SSB transmit
also come into play for AM transmit
operation as well. Speech processor, low
end rolloff, TX bandwidth, mic gain, and TX
EQ are all used for AM operation as well.
Transmit bandwidth in AM operation is
doubled from that shown in the SSB menu.
AM transmit bandwidth is still set from the
SSB menu, but the value selected is
doubled for AM operation. To select a 6 kHz
AM transmit bandwidth, select 3000 Hz in
the SSB menu as the transmit bandwidth.
Carrier amplitude for AM operation is set
automatically by ORION. The PWR control
on the front is used for PEP output power
setting in AM operation. A value of 100
would correspond to 100 watts PEP AM
output, or 25 watts carrier power maximum.

FSK OPERATION

Selection of the FSK mode will allow the
Orion to operate true FSK RTTY. The FSK
circuitry is controlled through the rear AUX
I/O jack on the rear apron of the Orion.
Pin 7 on the I/O jack is the MARK/SPACE
input. This input is typically connected to
the FSK output on a modem or terminal
unit. The Orion receives FSK using lower
sideband. The center of the filter passband
is preset so any bandwidth filter used will be
centered on the standard FSK
MARK/SPACE 2125/2295 Hz tones.

The Orion display indicates the transmit
MARK frequency. There is also a
user-control called FSK Tx Data in the
Other menu for selecting whether the MARK
is the low tone or high tone (the standard is
low tone). This allows the Orion to be used
with either TTL or open-collector keying
schemes.
The monitor function is available in FSK
mode and may be used to monitor the
transmitted tones. (See (18) MON in
Chapter 2).
Note: Early ORION transceivers supported
TTL data keying only and will require a very
minor modification to operate with open-
collector data keying. Check with
the Ten-Tec service department for details.

TRANSVERTER HOOKUPS

ORION provides the ability for a VHF
transverter to be connected to the rear panel
via the XVRT KEY, XVRT RF, and AUX RX
jacks on the ORION rear panel.
Both the XVRT KEY and XVRT RF
transverter support connections are
activated via the TX menu. Enter the TX
MENU (see description under TX MENU in
Chapter 3), and use the MULTI knob to turn
the transverter output on. This will activate
both the XVRT KEY jack and send RF
output through the XVRT RF jack.
