Autocom update

Have finished getting the parts to complete my Autocom unit. Purchased the Midland G7 off of eBay. Most places seem to be selling the radio for about £50 per unit. Going onto eBay, got two units with base station for £48. Bargain! So having got the radios I had to get the lead for the Autocom to connect it. Ordered from BikeBitz in Yatley online. Really quick service, ordered 3pm Monday, received Tuesday morning, very impressed. Opened up the parcel and noted that the lead I ordered for the radio was the wrong one. A quick phone call later and I had organised to pop into their store (was passing that way) and get a replacement. Wednesday afternoon went into the store and got the replacement. Really quick and really professional 10/10 for those guys.
Using the radio requires a change in the way that you speak. As anyone who has used PMR radios before know they are 'half-duplex' or can only receive or transmit. Where as a mobile phone is 'full-duplex' so you can speak at the same time as the caller. There is also a delay in the time between speaking, the transmitter sending and the receiver picking up. Autocom's manual suggests that you have a key-word that you start what you want to say with. So for example if you said "Turn left at the roundabout" the receiver would get "left at the roundabout". The suggestion is to start with "OK", thus you would say "OK... Turn left at the roundabout". With the use of radios there is a certain etiquette and when you finish a sentence to end with "over". Although the G7 radios have a tone they play once transmission has finished.

The range of the G7's is reasonably normal for PMR, however don't expect them to work over longer distances if you are in a concrete canyon. I would say, in a builtup area out of line-of-sight, about 200-300 meters is it.

For thier intended use as communication between riders though it works very well, with the speech through the Autocom being very clear. As long as you don't get too far away when entering a built up area they are great to be able to give instructions; or just chat on those longer trips.
