1. Chapter 5
Operating Exercise

2. Practiced with or without Radios
Introduction
This Exercise will:
Build Confidence
Improve
Sending Skills
Receiving Skills
Practiced with or without Radios
Introduction
1. This is a simple exercise designed to build confidence and improve sending and receiving skills using “Full and abbreviated callsign” procedures as described earlier. The exercise can be conducted on your Unit Headquarters using hand held Radios with Cadets positioned in separate rooms. Should you not have any suitable equipment available the exercise can be conducted by cadets speaking to each other across the room using correct radio procedures.

3. Aim Practice simple message sending Gain Experience using Prowords
2. To familiarise operators with simple message sending and give experience with using prowords

4. Teams Work in Teams of two If using Radios Use Landranger Maps
Use two separate rooms
Use Landranger Maps
Or the Map at Annex C of the Instructor Guide
Teams
3. It is suggested that cadets work in teams of two, and they are paired with another team of two. Each team should have a radio if available and a Landranger Ordnance Survey map which should be the same sheet number and edition. Alternatively the map at Annex C to this chapter could be used

5. Instructions Take turns sending and answering
Select a place name or feature
Make a note of its Grid Reference
Include the 2 letter 100km Grid Square Identifier
See example
Now send a message:
Instructions
4. Stations should take turns in sending information to each other and this information should be taken from the map they have been given. The sending station should select from a map the name of a town or place, road number etc. They should then calculate the six-figure grid reference which should include the 100 km square designator (the two letters before the figures) e.g. TQ This map reference should then be sent to the receiving station using the appropriate procedures; the receiving station records the message and finds the grid reference on their map. They then send the details, name of town etc., back to the other station using the correct prowords and procedures.

6. Example Full Callsign MRA 90B - THIS IS - MRA 90C - MESSAGE - OVER
MRA 90C - THIS IS - MRA 90B - SEND YOUR MESSAGE - OVER
MRA 90B - THIS IS - MRA 90C - NAME OF PLACE AT GRID - TQ 292 992 – OVER
MRA 90C - THIS IS - MR A90C - WAIT OUT
EXAMPLE
Full callsign procedure
MRA 90B THIS IS MRA 90C MESSAGE OVER
MRA 90C THIS IS MRA 90B SEND YOUR MESSAGE OVER
MRA 90B THIS IS MRA 90C NAME OF PLACE AT GRID TQ 292 992 OVER
MRA 90C THIS IS MR A90C WAIT OUT

7. The Receiving Station:
Example Full Callsign
The Receiving Station:
Looks up the Grid Reference
Replies as follows:
MRA90B THIS IS MRA90C – PLACE AT GRID -
TQ – IS BOTANY BAY - OVER
MRA 90C should now look up the grid reference and prepare a message with the answer and replies as follows:
MR A90B THIS IS MR A90C PLACE AT GRID TQ 292 992 IS BOTANY BAY OVER
MRA 90C THIS IS MRA 90B CORRECT OUT
Note:
If there are more than two stations using the same frequency, it will be necessary for the station with the Answer to call the Station (and await a response ) for whom the message is for.
Example:
MRA90B THIS IS MRA90C - MESSAGE - OVER
MRA90C THIS IS MRA90B - SEND YOUR MESSAGE - OVER
MRA90B THIS IS MRA90C – PLACE AT GRID - TQ – IS BOTANY BAY – OVER
MRA 90C - THIS IS - MRA 90B - CORRECT - OUT

8. Example If the reply is correct answer:
MRA 90C - THIS IS - MRA 90B - CORRECT - OUT
If incorrect the reply will be:
MRA 90C - THIS IS - MRA 90B Wrong – Verify your answer - Over
The answer should be checked and message resent
If the incorrect answer is given the reply will be “wrong, verify your answer”, the other station should then check their answer and send it again.

9. Example Abbreviated Callsign
A 90B - THIS IS - A 90C - MESSAGE - OVER
A 90C - THIS IS - A 90B - SEND YOUR MESSAGE - OVER
A 90B - THIS IS - A 90C - NAME OF PLACE AT GRID - TQ 292 992 – OVER
A 90C - THIS IS - A90C - WAIT OUT
5. Once Stations are familiar with using “full callsign ” procedures they should then practice “Abbreviated Call” procedures. An abbreviated call is when the first 2 characters of the Callsign are dropped. Therefore MRA 90 would be A90 and MRA90B would be A 90B.
EXAMPLE
Abbreviated Call
A 90B THIS IS A 90C MESSAGE OVER
A 90C THIS IS A 90B SEND YOUR MESSAGE OVER
A 90B THIS IS A 90C NAME OF PLACE AT GRID TQ 292 992 OVER
A 90C THIS IS A 90B WAIT OUT

10. Example Abbreviated Callsign
If the reply is correct :
A 90C - THIS IS - A 90B - CORRECT - OUT
If incorrect the reply will be:
A 90C - THIS IS - A 90B Wrong – Verify your answer – Over
The answer should be checked and message resent
A 90B should now look up the grid reference and prepare a message with the answer and replies as follows:
A 90C THIS IS A90B PLACE AT GRID TQ 292 992 IS BOTANY BAY OVER
A 90B THIS IS A 90C CORRECT OUT
If the incorrect answer is given reply will be “wrong verify answer”, the other station should then check their answer and send it again.
Note:
If there are more than two stations using the same frequency, it will be necessary for the station with the Answer to call the Station (and await a response ) for whom the message is for.

11. Summary Also practice using prowords: Use a combination of: Say Again
I spell
Figures
Use a combination of:
Town Names
Mountain Names
Road Numbers
Conventional Signs
Summary
6. Stations should also practice the use of other prowords such as Say Again, I Spell, Figures, Correct, Wrong etc.
7. When choosing places on the map use a selection of Town, Village, Mountain and River names in addition Road Numbers, conventional signs can be used.
8. Using this simple exercise will help build confidence and proficiency in using radio procedures.

12. Summary Prowords - Help
A 90C - THIS IS - A 90B – SAY AGAIN WORD AFTER NAME – OVER
A 90C - THIS IS - A 90B NAME OF TOWN IS-I SPELL- LIMA LIMA ALPHA NOVEMER FOXTROT APLPHA INDIA ROMEO – OVER
