  2. PART 1CB RADIOS

  3. Why talk about radio’s • Useful for when others are out of site, and for emergency situations. • Mobile Phones often won’t work in the bush • Just about everything these days uses radio waves, so it’s good to know something about them. • For example Televisions AM/FM radios, CB’s, remote control cars, GPS systems, mobile phones, garage remotes, etc all use work with radio waves

  4. SOME RADIO’S HAND HELD CB RADIO UHF MILITARY MANPACK VHF RADIO 4WD WITH LONG DISTANCE HF RADIO VECHICLE CB RADIO UHF

  5. CB RADIOS • CB stands for Citizens Band. These are a common two way radio anyone can get their hands on. • You can’t just use any frequency for any purpose. Different frequencies are set aside for different uses. • CB’S can be Hand held, or mounted in vehicles or buildings. • There are two main types of CB 27MHZ and 477 MHZ • CB’s are often used by truck drivers, or on construction or work sites, in vehicles by 4WDers, by trail bike riders, hikers, farmers etc…

  6. Hand held and vehicle mounted Vehicle mount CB and antennas, common in 4WD’s trucks etc Hand held CB

  7. Types of CB Radio in Australia • 27 MHZ (HF) – Generally longer range, larger antennas, less features. (‘old’ type) • 477 MHZ (UHF)– Clearer, line of sight, shorter range, more compact size, more features. MOST COMMON (‘new’ type)

  8. RANGE • 27 MHZ - up to about 30km • 477 MHZ - 5-20Km. Handheld units up to 5km. These figures will vary depending on particular situation

  9. Channel usage in Australia You can’t use just any channel for any usage here are the rules

  10. 477 MHZ UHF Designated channel usage

  11. Channel usage in Australia

  12. Using a CB Before you leave • Do a Radio Check, call each other to check it is all working. • Choose a channel to use, make sure everyone knows which one. • Choose the correct channels for conversations and Emergency. • Check Radio condition and batteries. Having trouble communicating? • Use a higher power setting. • Go to the top of a hill or raise your antenna higher. • Speak clearly and slowly if necessary. • Try moving closer to the other person. • You will may get better comm’s over large areas of water and flat or wet ground than dry ground or forests. • Do not waste batteries, but in an emergency don’t stop trying either. • Look after your radio and it’s antenna. It could be your best lifeline in an emergency.

  13. Using a CB Communicating • 27MHz CB’s generally have better range than 477MHz CB’s but are not as clear (due to the lower frequency). • Don’t interrupt in the middle of conversations, it gets very confusing. • Please don’t fill the air waves with immature crap. Note • For long distance outback travel you would use a HF radio or Satellite phone. CB radio range is too short.
