Present Objectives
{{lesson slide|00:03|4 min}}
* Why is communications important in SAR?
** The biggest problem you will ever experience in a SAR situation is lack of communication. 
** Critiques: "The first problem is always communications"
* Why professionalism, why standards?
** communicating clearly with other groups
** expectations of other groups (RCMP)
** working efficiently
** competence

{{lesson slide|00:07|4 min}}
* What communications methods have you seen used in SAR?
** commercial radios
** HAM radios
** FRS
** cell phone
** sat phone
** SPOT
** voice
** hand signals
** mirrors
* ''Discuss value of each''

{{lesson slide|00:11|3 min}}
* Basic Radio Theory
** all the wireless electronic communications methods are using radio waves
** radio waves are electromagnetic radiation, same as light, longer wavelength

{{lesson slide|00:14|8 min}}
* Wavelength / Frequency
** All radio transmissions have a wavelength
** The speed of radio is the same: 3 x 108 m/s (speed of light)
** The number of waves received at a spot per second changes with the wavelength.  Shorter wavelength, higher frequency.
* Bands:
** VHF: 30 - 300 MHz: 10 m to 1 m
** UHF: 300MHz - 3 GHz: 1 m to 10 cm
* Longer wavelengths bend around hills easier
* Shorter frequencies can carry more information, packed closer together
* Some frequencies bounce off the high atmosphere easier
* Simplex: Transmit and receive on same frequency
** one at a time
* Duplex: Transmit and receive on different frequencies
** simultaneously
** typically using tower: repeater channels, cell phones

{{lesson slide|00:22|3 min}}
* Power
** Power is measured in Watts (W)
** The more power the further the signal can be received
*** Generally: double the distance, 4 times the power
** advantages to less power?
*** Neighbours can share the same frequency
*** Batteries last longer
* Typical: 0.5 W FRS, 2 W GMRS, 3 W commercial handheld, 30 W commercial mobile, base station
** 5 W HAM portable

{{lesson slide|00:25|2 min}}
* Polarity
** compare with polarized glasses
** different types of antennas transmit and receive with different polar orientations
** keep antennas upright

{{lesson slide|00:27|3 min}}
* Signal Encoding
** AM: Amplitude Modulation
** FM: Frequency Modulation
*** more resistant to static interference
** Generally: established by band, fixed in radio

{{lesson slide|00:30|4 min}}
* Squelch
** radio waves always present, but is it a real transmission?
*** Electromagnetic noise, interference
** suppress speaker based on signal strength
** squelch button: remove squelch
** CTSS: Continuous Tone Squelch System
*** very low frequency tone added to transmission, if not present, suppress speaker
*** tone is so low can't be heard by human ear (maybe elephant, whale!)
*** FRS sub-channels
*** 2 sub-channels of same channel can't be use at same time

{{lesson slide|00:34|1 min}}
00:34
* "Channel"
** Combination of Frequency, Polarity, Encoding, and Squelch to transmit and receive on
** Listed on our radios so other agencies can program theirs to our channel

{{lesson slide|00:35|1 min}}
* Anatomy of radio
** power source
** microphone
** transmitter / modulator
** antenna
** demodulator / receiver
** squelch / speaker

{{lesson slide|00:36|3 min}}
* Types of radios
** ''show pictures''
** handheld/portable
** mobile
** base
** repeater

{{lesson slide|00:39|1 min}}
* Connectors & Mobile Antennas
** show pictures

{{lesson slide|00:40|8 min}}
* Use of radios
** Battery Replacement
** Using the controls
*** power, volume
*** channel selector
*** squelch
*** transmit (PTT)
*** external mic
** Posture of the user
*** Keep the antenna vertical and fully extended.
*** Distance from outside noise when sending.
*** Keep the mic about 2 to 3 inches away from the mouth at 45 degrees.
*** normal speech levels
*** Hold the mic button down momentarily (1 sec) before and after you speak. 
** Mobile Radio setup and use
** Base Radio setup and use
** Equipment and channels we have access to
*** Channel 1 - Emergency Services repeater
*** Channel 2 - Emergency Services talk-around (Simplex)
