-
* 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
+

* What communications methods have you seen used in SAR?
+
-
** commercial radios
+
-
** HAM radios
+
-
** FRS
+
-
** cell phone
+
-
** sat phone
+
-
** SPOT
+
-

-
* Basic Radio Theory
+
-
** all the wireless electronic communications methods are using radio waves
+
-
** radio waves are electromagnetic radiation, same as light, longer wavelength
+
-
 
+
-

-
[[Image:Communications-Lesson-Slides.pdf|page=8|200px|right]]
+
-
* 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
+
-
 
+
-

[[Image:Communications-Lesson-Slides.pdf|page=9|200px|right]]
+
-
* 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
+

+
-
* 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}}
+
-
[[Image:Communications-Lesson-Slides.pdf|page=11|200px|right]]
+
-
* Signal Encoding
+
-
** AM: Amplitude Modulation
+
-
** FM: Frequency Modulation
+
-
*** more resistant to static interference
+
-
** Generally: established by band, fixed in radio
+
-
 
+

[[Image:Communications-Lesson-Slides.pdf|page=12|200px|right]]
+
-
* 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
+

+
-
