I had the nightmares last week, because i was also praying to save the Thia footfall team 11players+1 coach stuck into the cave. IT was a very daunthing task to save them. They have into there already 14 days/2weeks without any proper food, sunlight , information. It was the coaches budhist monk training that helped them keeping togather as a group. They silently sat there and waited for their search.
Thialand is not india. It has budhist rule and they value human being. India has secular view points. Even in rescue we think in terms of caste !
But any way. This incident has something to do with the HAM Radio. How they were able to communicate to the surface and other cave rescue team.
The British team had brougth along with them the cave radios. These cave radios operate on the very low frequency. there are atleast three types of radios in use now. hyphone, tesla, etc. there is difference in the range depending on the type of antennas on use. whethere you use loop 1 meter or a big tail antenna of 15-20 meter. hi hi we have good lenght of wire at the cave. other freq are not able to span the distance of cave rock. so CB or any VHF could not be used. So, we have to design something. our G3TDZ had done very interesting designs.
They use down converter for cb radio. usb only as the power is very precisious at the cave.
i think i should try one crystal based design 5ok and test in on my farm. will tell ya.
