Asterix and others, I really wasn't intending to reply to his post, anyway here goes...
A few years back, Rob Thomas (121.5 on Avcom) approached me and explained the serious issues that the Mountain Club have in communicating in S&R situations. I was interested as he explained that he couldn't find anybody to manufacture a communication system allowing the S&R teams to communicate on Air Band, the 2 metre ham and PMR band and also a cellphone with a intercom in a Oryx helicopter. All this in a very high Helicopter downwash and high noise environment. He advised that he had heard our Chatterbox systems and these worked in a very high wind environment. Rob flew to Durban and we discussed the project at length. It was also understood by both parties that they had zero development funds available. So I decided to take the project on and accepted R5,000 as a token from them. (I designed this whilst working overseas when its raining!) We drilled this in 10 minutes but advised it would take some time as no development cash means we have given free time and materials from our side. It took us two years and is now complete. The rescuers wear a harness, the Oryx has a spider box (intercom box). We sell the systems at cost +50% and almost 30 devices have been produced. The same systems are being used by counter-poaching teams, Police, AMS and also Tanzanian anti-poaching teams. In memory of the Helicopter teams that crashed the comms box is named "4022". So if anybody wishes to "do their bit" and further aid these fellows, we are intending to make a hitch up for the Oryx ICS and that needs cash ! This will allow the S&R teams to link the comms spider to the Oryx, 109/119 and also 44s and similar. It can only help.

I am led to believe that they now have a sponsor but as always after the event...
Asterix if you wish to drive this further, the product is available for counter poaching and saving our Rhinos. It is perfect if used with two Vee rabbit antennas on a trike King post, one for the PMR band and the other a Air Band radio. This could be sold on similar terms. But somebody has to drive the project...
I am not insulted but there are people out there "doing their bit" so there are things happening behind the windows.....Contact Melanie and she will co ordinate this.
