i have used the TED wireless start with my Lynx system for 42 track and field meets this year without any missed starts -at all!!. Most recently, I timed a 5 day meet in lightening plagued Florida where one day we had 223 races -all without a hitch. (note: lynx hardwire/normally closed gun sensor picked up stray starts when lightening was about 20 miles away or so)
In my testing, I have found that: 1)at every venue i run a frequency scanner (Radio Shack) to check if anything is in the 433.5 range of the ted units...just for peace of mind....so far all has been clear though have had some very close in the range of 434 (though units worked fine) 2) mount the reciver as reasonable high as possible.
For example, if i am up in a press box i have the unit right in front of me so that i can monitor it. If i am at track level/under a tent then i either mount the unit up with my camera or on the top rung of the tent using a Bogen c-clamp and Bogen umbrella adjuster so that i keep the antena verticle. So far, doing this has allowed trouble
free operation of my wireless start, wirelsss ethernet, and wireless phone/communication system being used all at once.
