Re: [WISPA] band pass filters
What Ethernet to USB converter are you using because we have been looking for a good one?

Re: [WISPA] band pass filters
A single-channel bandpass filter will help most poor-to-middling receivers by protecting it from overloading from the off-channel signals that the cheap receiver front-end would otherwise let come barging in, desensitizing the receiver and reducing the signal-to-noise ratio.
