having the same f'in prob with my LC1...

It's the only thing holding me back from using my wideband

tried it with 2 laptops, same thing both times.....

[beamar]

think I might know my prob.

Didn't have the wireless plug in the other analog socket.....

I hope that was my prob, we'll see tomorrow....

I had to buy an adapter to make the LM1 cord fit my usb port. The company that makes the adapter has a web site with a free download that makes the laptop "look" at the usb port as if it were a serial port. But that is the key. Let me know if you need the website.
