3.7A.10 Net Numbers.The net number is used in the
anti–jamming mode in the same fashion as a radio fre-
quency in the normal mode of operation. The net number
enables multiple users to operate simultaneously on a
non–interfering basis with other users while sharing a
common WOD and TOD. There are three nets available to
the operator:
(1) Frequency Managed A–Nets (FMA–NET).
(2) Training Nets (T–NET).
(3) Frequency Managed Training Nets (FMT
NETS).
a. Frequency Managed A–Nets (FMA–NET). The
FMA NET provides four frequency tables or hopsets.
There are 1000 possible nets for each hopset. The fre-
quency table to be used is determined by the geographi-
cal area of operation. One large hopset has been coordi-
nated for use in NATO–Europe and another large hopset
for employment in non–NATO countries. The net number
begins with an ”A” and is followed by three digits between
000 to 999. The last two digits designate the frequency
table to be used. Nets are selected IAW ABB.BCC where:
(1). A = A (Active)
(2). BB.B = Desired Net
(3). CC = 00 for basic HAVE QUICK A & B NETS.
= 25 for NATO–Europe
= 50 for non–NATO Europe
= 75 for future use.
b. Training Nets (T–NETS). Each Major Command is
assigned a training WOD for daily training and radio main-
tenance. Training WODs may be loaded using a single
WOD or MWOD methods. All training WODs are initial-
ized with 300.0XX in channel 20. XX sets the frequency
hop rate for the WOD in a SWOD only. In this training
mode, the radio hops between the five frequencies loaded
in with the WOD (locations 19 to 15) and five training nets
are available. As shown below, a net number ending in 00
selects a training net.
(1). A00.000
(2). A00.100
(3). A00.200
(4). A00.300
(5). A00.400
c. Frequency Managed Training Nets (FMT–NET).
To expand the number of training nets available to HAVE
QUICK II users, 16 frequencies (Nets) have been loaded
into the radio and are permanently stored in the radio
memory. To use the FMT nets, a training WOD must be
entered first. The FMT Nets are numbered A00.025
through A01.525. All six characters must be selected and
the last two digits must be 25. Selection of an FMT NET
greater than A01.525 or ending in 50 or 75 will result in a
pulsating tone.
