Bike to Bike Comms

A few random photos detailing our bike to bike UHF Multi-user Comms practices.
  1. Acoustic Tube Earplugs
  2. Velcro Armband Radio 
(for temporary or permanent use)
  3. PTT fitting on Africa Twin 
(we like these much more than buttons)
  4. Africa Twin Radio Installation 
(front mount & quick removal)
  5. BMW Baehr Installation_Business end 
(this radio gave jackplug problems)
  6. PC800 installation showing  
extension lead & headset plug  
needed in this case
  7. PC800 Radio Mounting  
(radio removable - harness mostly stays in situe)
  8. Radio Pack on Spyder

  15. Frontmount Radio  
Piaggio MP3
  16. DB9 interface for WT419  
(fixed wiring avoids jackplug woes)
  17. Miniature Quick Fit Radio  
(How simple & small can you get?)
  18. Arm Band Radio  
(One Rider only ever uses an armband radio)
  19. Pushins - 30 to 40dB of noise attenuation. 
Probably the most effective ear plugs so far.
  20. Comms Intelligibility & Audio frequency band dependence
