3CAP Radio Operator Licensing
TWO Levels of Operator Licensing
- Communications Orientation
- 2-3 Hour Class on
- Standard Operating Procedures
- Local Operating Procedures
- Entitles CAP member to operate a CAP Radio
- Issued a Radio Operator Authorization (ROA) by
Ohio Wing
- Advanced Communications User Training
- 4-5 Hour Class
- Pass the Advanced Communications User Test, CAPF
119 - Entitles CAP member to be assigned a call sign
for their radio - Required as part of the Communications Specialty
Track
The regulation for all CAP Communications is CAPR
100-1
4CAP Radio Station Licensing
- CAP is a considered a federal agency for radio
licensing - Federal agencies are not allowed to use services
allocated exclusively to the public sector for
their business - Amateur Radio and Citizens Band cannot be used
for CAP business - Family Radio Service (FRS)
- On ES missions limited to communication with
victims to expedite a rescue - May be used for all non-ES mission activities on
a non-interference basis

6CAP Communications Systems
- CAP Frequencies
- HF - Long-range (50-1000 miles)
FAA Aeronautical Frequencies
- Uses FAA frequencies
- Communicate with all radio equipped aircraft
- Satellite Digital Imaging System (SDIS)
- Used for digital imaging
- Data relayed through satellite
Range determined by time of day, frequency, and
sunspot cycle
- VHF - Short-range (5-150 miles)
- ISR (Intra Squad Radios)
- Short range (1/2W or 500mW)
- Similar to FRS radios
Range determined by radio horizon
HF Static
Voice is the primary means of communication

HF SSB

8Repeater Operational Advantage
Output
Input
Repeaters increase the range of mobile stations
due to the high profile location typically
covering a 20-50 mile radius
9Inside the Repeater
A repeater retransmits voice/data if it hears a
discrete sub-audible tone Sub-audible to the
radio audio, but still audible to the human ear,
especially with receivers (scanners) that do not
filter out the sub-audible tones. The standard
tones range from 67Hz to 250Hz 38 standard tones
to select from.

Mike Button
Tone Decoder presses the Push To Talk (PTT)
button to turn on the repeaters transmitter
Tone Decoder listens for either the universal
or site specific tone on the incoming signal
Radio must be set to the correct 1) transmit
channel, and 2) sub-audible tone to use the
desired repeater
10Airmobile use of Repeaters
- Primary mode of operation should be simplex
- Repeaters can be used if simplex not possible
- Selectively use a repeater through use of its
assigned sub-audible access tone - The key is to limit use to a single repeater
11FAA Aeronautical SAR Stations
- Air-Ground Communications on FAA aircraft
frequencies - Aeronautical Search And Rescue (SAR) ground
stations operate on two Aircraft Frequencies - 122.9 MHz - TRAINING Only
- 123.1 MHz - ACTUAL Missions Only
- Ground Station Call Signs assigned by
geographical location - THIS IS Lost Nation Base OVER
ELTs - Training Actual
121.775 MHz Training transmitters 121.5
MHz Actual ELTs
12Basic Radio Station Operation Summary
- Power (On/Off)
- Usually part of Volume control
- Battery powered radios should be turned off when
not being used to conserve the batteries - Volume
- Set to easily hear stations but not annoyingly
loud - On portable radios the higher the volume, the
more battery power is used and the sooner the
battery runs out - Squelch
- Adjusts the point where audio and noise (hiss)
are suppressed (quiet) - Adjust until noise is heard and then back off to
just past the point where the noise stops - Some newer radios do not have a squelch knob
13Basic Radio Station Operation Summary (contd)
- Channel Selector
- Selects both receive and transmit frequencies
- Unless it is a corporate radio, there is no
assurance that the frequencies are set the same
on the channel selector. Know the frequencies in
use and how your radio is set up or programmed - Consult the person who furnished the radio for
the specific settings for the radio - Microphone
- Speak into the microphone using a normal speech
level - Dont yell or whisper Shouting does not
increase intelligibility or range - Push to Talk (PTT) Switch
- Press the PTT when talking Release PTT to listen
- Monitor the channel for a few seconds before you
transmit to ensure that you dont interfere with
other traffic prior to pushing the PTT

25Intra Squad Radio (ISR)
- Similar to FRS radios but
- on shared-use
- federal government frequencies
26Intra Squad Radio (ISR) (contd)
- Designed for ground team use and large functions
like encampments and schools - Not issued to individuals - issued in deployable
packages - Wont talk with CAP VHF-FM radio system
- NHQ furnished radios and cases, but no batteries
- Cost of ni-cad battery and charger almost equal
to cost of radio itself
26
27Intra Squad Radio (ISR) (contd)
- Ni-cads available run 10 hours before needing
recharge - Alkaline AA batteries last 30 hours max before
requiring replacement - Commanders, and ES Officers should plan for
readily available batteries - Incident Commanders and Mission Coordinators
should anticipate battery expenses for actual and
practice missions - ISR battery costs are reimbursable on CAPF108 if
mission/SAREX is reimbursed (with receipts,
complete forms, etc.)
27
28Intra Squad Radio (ISR) (contd)
- Project Officers for encampments and training
activities should anticipate and plan for battery
costs - Flight-line supervisor should use VHF-FM (Ch4) to
marshal pilots in aircraft - ISR frequencies are shared with other DOD agencies
28
29Zulu Time is Standard Time
- Known as Universal Coordinated Time (UTC) based
on an accurate atomic clock - Similar to Greenwich Mean Time (GMT) - based on
mean earth rotation
Zulu time is the same, no matter what time zone
you are in.

Military/NATO/Letter time zones The following
table lists the Military time zone abbreviations,
click on the time zone links for more information
about individual time zones and where they are
used. The basis for this is Z - Zulu time - Zero
meridian time - the same as UTC It's a convention
to assign letters to time zones, where Z Zero
meridian, and Zulu is the word that represents
the letter Z, when it's used in communication. It
is sometimes used in the US Military and NATO in
conjunction with 24 hour clocks, and is also
popular to use in movies to reference time.
Other letters/words are used for other time
zones than UTC, most based on the right or
reverse order of the Alphabet. Note that 'J' is
skipped ('J' - Juliet refers to current local
time of the observer). There are 25 time zones
defined here, but 26 letters in the English
alphabet.

38Radio Net Operation
A Formal Net controls flow of traffic on a single
radio channel

- Maintains net discipline by controlling who is
talking - Must be contacted first for permission to contact
another station - Columbus 10 THIS IS Columbus 404 with a
Priority message for Columbus 710 OVER - Sample Net Check-in (C10 is the NCS)
- Columbus 10, THIS IS Columbus 404 with no
traffic, OVER - Acknowledging readiness to receive traffic
- "THIS IS Columbus 710, GO AHEAD with your
traffic OVER" - Acknowledging receipt of a message
- "THIS IS Columbus 710, ROGER your message
OUT"

56 QUESTIONS?
"I am often asked how radio works. Well, you see,
wire telegraphy is like a very long cat. You yank
his tail in New York and he meows in Los Angeles.
Do you understand this? Now, radio is exactly the
same, except that there is no cat. Attributed to
Albert Einstein
