700' has thus been established as the maximum effective range of this broadband voice communications system at the present transmit levels. This being in calm weather and in medium boat traffic. It could still be understood even with loud boats within the line of site of the transmit and receive stations! Deep transmission testing will soon follow as these initial tests were conducted at relatively shallow points (about 3' to 5' deep) within a fairly deep body of fresh water (45'-90'). Salt water testing is also soon to be investigated. David Bartsch Windows 7: Unclutter your desktop. Learn more. |
