Spectra Logic TAC/COM SERIES - Manual (Page 96)

Tac/Com Control Head Manual SM06 Rev. 4.10
This is used where the tones are needed only to open the repeater and serve no RX
squelch function.
3.6.2.3
POWER=
Some radios, such as NAT's NT-series and the RT-9600/7200 support a high and low
power transmitter function. Many radio station licenses have power restrictions at
altitude, and must be set to low TX power above 5,000' for legal operation. This may
also be required to prevent repeater interference at altitude, or to permit secure
operations.
3.6.2.4
TONE DISP=
New generation software now permits the user to define the tone presentation to suit
local operations on a radio-by-radio basis. This selection can be set to the tone
frequency referred to as FREQ, or to one of several codes. The sequential numbers for
the first 32 EIA tones are referred to as 1-32. The alphanumeric codes for Motorola
radios are referred to as MCODES. The shifted octal codes used by Wulfsberg are
referred to as WCODES on the status line.
To select the desired tone display option from the list, chose the desired display mode
with the SELECT switch. The options are 1-32, WCODE, MCODE and FREQ. Note
that the FREQ option will not appear if the DPL tones have been selected ON in the IAC
edit mode. Refer to Section 3.5.4.4 for more information.
3.6.2.5
SCAN=
For NAT series transceivers, the option of scanning a LIST, PRIORITY channels, or on
newer generation control heads, LIST + PRIORITY is provided. The Scan List channels
are edited in the second last digit on the ID line from normal channel edit mode. For
more details on scanning refer to Section 3.9.
3.6.2.6
P1=, P2=
The Priority 1 and 2 channels are selected by toggling the CHAN +/- switch. Two
channels are selected for each bank of channels (a through d). When the scan option is
selected to List, the priority channels are not active but are retained in memory.
3.6.2.7
GUARD RCVR=
The RT-9600 guard functions can be from either the front panel (U interface), or the
status line, depending on which type of interface has been installed in the control head.
If the status line is used (R or P interface) the line appears as GUARD=0 (off), 1, or 2.
For Flexcomm, the guard RX may only be enabled or not from the status line, as only
one channel exists. Front panel guard functions refer to guard transmit operation.
