| | USB Tower range
|
| Hi, I recently bought the RCX2.0 and I am a little disappointed at the range for the USB tower. Though configured to be at long range I doubt I can implement a range greater then 5 or 6 feet. Is this normal.? Am I missing something.? Paul Reedman (21 years ago, 7-Jan-04, to lugnet.robotics.rcx)
