TeleBT at 38.4kbps is good to about -115 dBm APRS to my Yaesu FT1D is good to about -125dBm A simple RDF beacon is good to probably another 10dB below that > Keith, based on the previous thread, it seems like I may need to have > my TeleBT calibrated too? Is there something else I should try? With version 1.5, you can crank the bit rate down, which will improve range quite a bit. I'm experimenting with a better receiver design to see if we can't beat APRS (which is pretty miserable as a modulation scheme). -keith
