I revisited an old project tonight. 434 MHz TX and GPS, easy radio module. 19k2 data rate Sending "No lock" takes 9.6 ms on the busy pin, or 4.6 ms of actual data. Sending VK4TEC-12>APRS,WIDE: <<UI>>:=2734.45S/15306.21E'SATS 03 RAW,27344551,S,153062152,E Takes 76 ms on busy pin, or 44 ms of actual data. The down side is the power out is only low, mW Andrew VK4TEC http://www.tech-software.net/glider_tx.php -------------- next part -------------- An HTML attachment was scrubbed...
