If you are operating a subnet involving many teams during a scheduled exercise you may find that calling for all check-ins will cause a pile up and a lot of doubling.  More likely, however, the check-ins will naturally spread out over quite a few minutes for two reasons (a) The operators will probably need to check into a Resource Net first and arrive on your frequency over several minutes.  (b) During an actual deployment operators will become ready to check in over an extended period of time. So, unless your subnet is scheduled to open at a particular time and you expect many operators to be ready to check in at that time you probably don’t need to divide the check ins ranges of call-sign suffixes although you are free to do so if you wish. Here is a [[Script for Checking in Stations Alphabetically by Tactical Call Signs]].

In fact, your challenge may be quite the opposite: Your operators will arrive over an extended period of time and any information you provide before checking people in will only be heard by a few operators.

To facilitate communication between teams and between teams and the ECC you should create a table of ARO tactical call signs and the NET teams or neighborhoods that each team ARO represents. See [[Logging Procedures for Subnet Control Operators#Instructions for using Stations Participating Form|Instructions for using Stations Participating Form]].

What To Do If Stations Attempt to Check-In That Are Not Part of the Exercise
====== What To Do If Stations Attempt to Check-In That Are Not Part of the Exercise ======
 
Most amateur radio nets attempt to be very open to guests. During exercises and deployments, however, it is usually inappropriate for guests to check in. If a station attempts to check in that is not part of the exercise or deployment you should politely explain that the circumstances do not allow the extra time that would be required to communicate with guests.

What To Do If More Than One Operator from the Same Team Tries to Check In
====== What To Do If More Than One Operator from the Same Team Tries to Check In ======
 
A slightly different circumstance occurs when more than one operator from a particular team attempts to check in.  If this happens you should explain that only one operator should represent a particular team at a time.  You can also mention that they should use the same tactical call sign if they decide to change the operator representing their team during the exercise.

=== Calling for Relays ===
=== Calling for Relays ===
The strength of communication will vary from exercise to exercise and operator to operator based on factors like location, elevation, available transmission power and sensitivity and selectivity of receivers. Note that there are many combinations of these factors in a region including a subnet controller who may be in a different location and team AROs in varying locations depending on who is available and the nature of the exercise or deployment.  This unpredictability of simplex communication means that you and the other operators must be ready to ask for and provide relays.  There are at least two cases to consider.

==== [[Procedure for When Some Operators Cannot Hear Net Control Operator]] ====


# Stations you may not hear.  To account for this possibility, expect that other stations may offer to provide a relay by using the proword Relay preceded by the precedence of the traffic they wish to relay.  If no precedence is given, you should assume that its precedence is Priority.  If you are not sure that your team AROs are aware of their relay responsibility, you should ask if any station has a relay. When an ARO indicates that they have a relay tell them to go ahead if you are not handling traffic of higher precedence, there is no traffic of higher precedence and there is no traffic of equal precedence ahead of the requested relay. Otherwise, tell the relaying station to stand by after obtaining their tactical call sign.
==== [[Procedure for When Net Control Operator Cannot Hear Some Operators]] ====
# Stations that may not have heard you.  To account for this possibility, choose a station that you believe to be in a different part of your region with equipment sufficient to be heard by other stations and ask them to relay your announcement or request and stand by for them to either say “Nothing heard” or “Relay”.

Teams may need to contact other teams to share information or coordinate their activities.  These contacts may be (a) tactical communication using a frequency proposed by one of the teams; (b) tactical communication using a prearranged frequency; (c) formal messages between teams in the same region using NET Form 8; or (d) formal messages between teams in different regions. During the exercise you should expect some teams to use option (a).

==== a. Tactical communication between teams using a frequency proposed by one of the teams. ====
==== Tactical communication between teams using a frequency proposed by one of the teams. ====
The two teams usually won’t choose a frequency in advance. In this case, the team seeking to initiate the communication should find a frequency that appears to be available and ask the subnet controller for help in communicating the proposed frequency to the other team and asking if they are willing to change frequencies. The team may want to propose a UHF frequency or possibly a VHF frequency unless cell service is available.  Unless additional Amateur Radio operators are available to handle the direct communication, one or both of the operators may need to temporarily check out of the subnet and then check back in when they are finished with their direct tactical communication. In this case they should keep their direct communication as short as possible so they won’t miss important communications from the ECC.

==== Tactical communication between teams using a prearranged frequency ====
Tactical communication may be somewhat easier if the teams involved have agreed to use a particular frequency for such situations.  If that is the case they may proceed to attempt to establish communication using the agreed upon frequency, assuming the other team is monitoring the frequency.  Otherwise one team may need to use the regional frequency to let the other team know that they want to establish direct communication. Also, if either operator is currently checked into a regional subnet, that operator should find an alternate operator to take over with subnet communications or the alternate operator may handle the inter-team communication.  If the former is chosen, the operator currently checked into the subnet should inform the subnet controller before leaving the subnet frequency.  If no alternate operator is available and communication with the other team is particularly important, the operator can request to be checked out of the subnet and then check back in when they have complicated their direct communication.

==== Routing formal messages within a region ====
The other major case is when a team has a formal message that they want to route to another team.  In some cases they may be able to do this using the tactical communication method above.  In other cases it may be better to route a formal message via their subnet controller.  If the team to receive the message is in the same region the subnet controller may be able to read the message to them.  Or, if there is a strong simplex communication path between the two teams, the subnet controller may give the originating team permission to use the subnet frequency to read the message to the receiving team.

==== d. Routing formal messages between regions ====
==== Routing formal messages between regions ====
The situation is even more complicated if the team to receive the messages is checked into a different regional subnet than the originating team.  In that case, the subnet controller may need to route the message through the ECC radio room via the Tactical Net.  Alternatively, the controller could transcribe the message into a Winlink ICS 213 and route it to the other subnet via a Winlink gateway. The receiving subnet controller could then read the message to the receiving team.
