So if I know the chipset where do I find performance info on that?
Seems I remember there was a gov. link for that but probably can't find
it now, for the tests? But look at their advertised receive sensitivity
ratings, that sounds good on the surface -91dbM at 11mbs

Have to check their return policy but the specs says usb 2.0 "only".
The first unit is 2.0 only the second one (200mw) is 1.0 or 2.0
The first radio is 500 mw output via an amplifier, but I'm more
concerned about the receive end of matters. Also any amplifier will
also increase the noise level on the receive side right?

Yeah the price is a ripoff, but might be worth it for convenience of usb
unit. Have to find out the chipset as I also want to know what software
it is compatible with. The OS is not an issue, they state they have
drivers for 98SE, but I've heard that story before. Thanks for your
usual good answer, this group would be toast without you.

yeah, no guarantee, no buyee
