Motor Talkie      Motorcycle communication  system   (temporarily out of stock ! )

The Motor Talkie is a self contained sophisticated microprocessor  controlled rider /pillion , bike to bike communication system and operates in stereo in both the rider and pillion headsets , it enables one to talk to other similarly equipped ( any bike to bike units)   motorcycles using a UHF CB transceiver  (not supplied ) 
it comes supplied with :
-Two stereo earspeakers that velcro into the helmet  and a boom  microphone ,
-MP3 input cable with 3,5 mm stereo  right angle plug ,
-Cell-phone connection cable terminated in a right angle  2.5mm stereo plug, (it  must be "auto answer" phone)
-External cable for cigarette lighter socket power connection .
-Walkie talkie connection cable with Handlebar attached PTT button   ( transceiver not supplied) 

Ask your Motor Talkie supplier what type of walkie talkie to use with this system as different models of handheld transceivers have different  external  mic/earphone connection  sockets  that might not be compatible with the cables supplied  .see below 

They say a picture is worth a thousand words so I have included a picture and a guide to operating the system 
The control unit is a well made water resistant  box with dimensions 12mm thick 60mm wide and 120mm long.

Quick Start Guide  

The control unit makes use of small  water resistant ( not water proof) "Mini-Din" polarised  multi pin connectors . These must be connected carefully or you will bend the pins. Before plugging together ,look at the socket and plug pins to see you have the correct mating connection  and rotational alignment ,  then  firmly press together . There is an arrow on the plug and matching socket to assist correct alignment .
 You have the option of connecting the unit to your motor cycles existing 13.6 Volt system ( negative earth) or place a pp3  9volt alkaline battery inside the compartment.

 Features:

1.      helmet headset device    ( rider )                                    6. Power jack

2.      helmet headset device   ( pillion )                                   7. Volume control of microphone

3.      PTT / transceiver                                                               8. Power indicator

4.      Mobile phone jack   (2.5mm  )                                         9. Volume �-�

5.      CD/MP3 player jack   (   3.5mm stereo)                        10. Volume �+�

Operation:

A. Selection of Power Supply

-                 Connect the control unit  to an external  power supply (6V-15) ie the motorcycle electrical system (negative earth) . Be careful to observe the correct polity as an incorrect connection can damage the unit and void the warranty, then by plugging in  either of  the  helmet headsets, it  will automatically turn the unit  on and a red L.E.D will light on the front of the unit.

-                  If you have inserted a 9volt battery into the unit , disconnecting the external power  supply,  will cause the unit to automatically use the internal 9V battery . Use a 9v alkaline battery or a rechargeable if not utilising the external power supply. 

B. ON/OFF Control

-                   There is NO external OFF/ON switch ,the  unit is automatically switched on when either  helmet headset is plugged in  , The red  power indicator will illuminate

C. Volume Control

-                  The Intercom volume adjustment is the small black knob  at the top, next to the three input connection cables, clockwise for full volume,  there is NO switch function with this volume control.

-                  All other audio inputs ie (Aux/CD/MP3/talkie�s)  can be adjusted by pressing and holding the + button or -- button on the front  of the unit and releasing when the required volume is achieved

D. Use of the Moto Talkie

 Assuming the unit has a power supply

1.        Rider Pillion function

- Install the headsets  into the helmet  making sure the ear-speakers are directly over the ears (this is important) position the microphone( next to the mouth)  on the helmet to find the best place for the microphone  attachment  ,when satisfied  THEN place the sticky velcro wool on the surface of the helmet . Plug into the control unit , the intercom  function is immediately available ,set the operating volume with the small volume control next to the cables.  position the microphone at the mouth , Talk loudly and clearly , adjusting the volume to suit.

2.     UHF Transceiver connection.

-  ( Establish communications between the two radios first,Set  the same  channel (and CTCSS code if used ) ) set a comfortable listening volume on the transceiver,    plug in the  helmet headsets (one or two), and  the two way radio interface cable . Connect PTT device to the left handgrip by way of the velcro straps, plug in the  interface cable into the transceiver ext headset plug .( you must have the correct plug that matches the transceiver as there are over seven  variations to the transceiver  external headset connection) , pressing the PTT button should enable you to talk , releasing the button will enable you to listen.  
For good communication range don't put the radio in your pocket but mount it up out in the clear ,out in the open where the antenna will get a good clear "view"

 -    When the control unit detects speech  from the transceiver,  the  music will be reduced in volume by 50% , Three seconds  after the speech has ceased , the music will resume to its original volume.

3.      Mobile phone use

-    Your phone must be able to "auto answer " with an external headset, and have a 2.5mm external headset socket. some phones need an adapter plugged into the bottom to enable this.( see your Moto Talkie supplier)  Set your mobile phone to "automatic answer" mode as if using the external headset .

-    Connect the  mobile phone to the control unit by way of the supplied  curly cable (2.5mm stereo plug each end) a mobile-phone-serve-first system will be initiated  and connected

-    When the mobile phone call is received, the caller  message will be connected  directly to  the headsets ( rider and pillion) and  the  other audio systems operating will be disabled ,  10 seconds after terminating  the  mobile phone  contact, the disabled audio functions will appear. 
 NOTE: If the calling party does not speak  for a time period of greater than 10 seconds the Motor-talkie assumes the  call has ceased and turns the music back on again . so make sure you don't monopolize the conversation or the music will come back on .  

Note: some Digital phones  eg "Vodaphone" system phones can cause a "Buzzing"  interference on the mototalkie , reposition the cellphone to minimize this RF pickup .

4.     Music Input

-  Plug in CD/MP3 player into the 3.5mm socket , the driver and passenger can listen to music in stereo!

-    When the control unit detects speech  from a headsets microphone, the  music will be reduced in volume by 50% , three seconds after the speech has ceased , the music will resume  its original volume.

NOTE:  The Motor-talkie is supplied with its own manufactured headset unit , they are NOT the K series  that PHS   sells ( different electrical connections )    however they are still very good !

Impressions
Just back from a 3 day ride on the Ol '  850 Commando, I had taken the newly modified Motor Talkie with me to test it out . I had my Nokia 3230 cell phone ( with 2.5mm plug to base adapter)  AM/FM radio for music , bike to bike cable with GME  TX610 walkie Talkie  unfortunately I did not have a pillion but I have previously checked that  and it was fine . I had set the cellphone to Auto answer with a headset plugged in , I received a couple of calls  and was very impressed , the communicating party said i was  clear as a bell with no problems hearing me at 100 Kph The cell phone call drops the AM/FM  music / walkie talkie and it does not reappear for 10 seconds  . This time period is for the received voice of the calling party to keep the Motor-talkie active so it knows to turn off the sound from the music and /or the walkie talkie .  If the calling party does not speak  for a time period of greater than 10 seconds the Motor-talkie assumes the  call has ceased and turns the music back on again . so make sure you don't monopolize the conversation or the music will come back on . I also noted that when you spoke into the mic ,the music level dropped  in volume  and reappeared when you stopped talking .  The received signal from the walkie talkie  causes the music to stop too, and then reappear 3 seconds after the walkie talkie signal has ceased. the volume can be adjusted by use of the two large waterproof plus and minus buttons on the unit . I suspect the Motor-talkie is quite hungry on power when all inputs are running  I suggest for long term use, it not be run on the internal PP3 Alkaline  9V battery but that the external power cable be connected to the motorcycles 12v system . All in all a very impressive system for the price !

These are some of the radios I have tried with the Motor-Talkie
