Hello Wolf,
Yes, I'm aware that OE is Austria. Your previous bulletin where you first
mentioned the 20 MHz bandwidth, was a responce to Hank W0RLI. I mentioned
USA for that reason. Re the bandwidth. Spread spectrum is wide band by
the nature of its Bi-Phase modulation. Most of the TX power in a spread
spectrum transmission falls between the first two nulls, which are determined
by the bit rate. In theroy, the outer sidebands can be filtered off. What kind
of filter one would use at 2450 MHz, I don't know. To be effective, a filter
of < 0.1% bandwidth would have a fairly high loss.
