Arpus-

Could you discribe the situation a little more in depth? Specificly, were physicly are the radios in relation to eachother? Do they have a clear line of sight to eachother? Is one close to the car frame? Are they both out on a test bed?

Also, what are you using for the OI's power supply? It should output 9volts 1500mA. Using underrated supplys will get all the lights to blink and look healthy, but the radios may not have enough power to communcate. In anycase, range will be severly affected.

If you have not done so already, place both radios a few feet apart with a clear line of sight. If they do not manage to establish a link within 10 to 15 seconds, they are probably damaged (most 'bots manage to link up under 3 seconds).

Check that the power supply is adequate, both radios start with a clear line of sight and that both are placed away from anything that could be 'noisy'. I susepect that a car frame could present a serious problem with communication. I would strongy suggest that you place the reciver high up and away from the rest of the car if feasible.
