TM 11-5895-1412-12&P
Frequency ranges are as follows:
LF
0.0001-1.9999 Mhz
2.0000-29.9999 MHz
VF-FM
30.000-87.975 MHz
VHF-AM
108.000-149.999 MHz
UHF
225.000-399.999 MHz
EXTRA
0.0001-9999.99 MHz (includes those frequencies not in other
ranges)
Frequencies less than 30 MHz are rounded to
point.
Frequencies equal to or greater than 30 MHz
after the decimal point.
the fourth digit after the decimal
are rounded to the third digit
Rounding up occurs for values of six or greater in the extra digit.
IF A NET IS NOT ASSIGNED ANY FREQUENCY INFORMATION, IT IS ASSUMED THAT NO
FREQUENCY IS NEEDED.
Enter into the NET TYPE column the net type. The types include PRI (primary),
ALT (alternate) and RTS (retransmission). The default type is PRI.
The function key selections change when the cursor is placed in this coiumn.-
To select a net type use the following function keys:
(f1) PRIMARY NET
(f2
(f3
(f4
(f5
(f6
(f7
(f8
ALTERNATE NET
RETRANS NET #1
RETRANS NET #2
RETRANS NET #3
RETRANS NET #4
RETRANS NET #5
RETRANS NET #6
A PRIMARY NET is used under normal mode operating conditions. An ALTERNATE
NET is used when the PRIMARY net communications cannot be maintained due to
jamming or interference.
A RETRANS NET is assigned to a retrans (radio relay)
operation.
If anything other than PRI is used as a net type, a corresponding
net must be given.
There is a 10 MHz separation between a RETRANS net and its
corresponding net as well as the alternate net.
The CORRESPONDING NET item is used only if the net is an ALTERNATE or RETRANS
net type.
The net number used refers to the DESC ID of the PRImary net to
which it corresponds.
Enter into the RESTRICTIONS column the frequency restrictions that have been
placed on the net.
Up to eight restrictions may be applied to a given net.
The restrictions are entered using the letters in the range A-P. Each letter
identifies the explanation of how the frequency is to be restricted.
For
example, “A” may indicate the frequency cannot be used in a given geographical
area.
Do not use commas between restrictions. Nets that have a fixed
frequency requirement should not receive any restrictions.
