It's licensed equipment currently in the 950MHz range that we are converting to operate in the US amateur band between 902-928MHz. We're licensed hams and plan to use the radios for digital voice and data links between remote sites. John --On Monday, June 16, 2003 16:28:20 +0200 Nicolas Bougue

I'm working with what the radios support -- which is synchronous RS-422. These are some surplus radios that have quite a bit more range than 802.11b (though they're not nearly as fast). They are 5 watt output, full duplex narrowband radios that were spec'd for paths of up to 30 miles. We nee

Do you really want serial type and sychronous ? If not, a standard wifi 802.11b is effective and supported by linux, but i suppose you already knows that. On Sat, Jun 14, 2003 at 07:57:44PM -0400, John Ackermann N8UR wrote: > Hi -- > > I'm trying to implement a wireless point-to-point link using
