Please make sure the following:
- The openSPOT2 is in C4FM Half Deviation modem mode (FT70 only supports half deviation mode)
- The openSPOT2's TX power is set to 100%
- You've ran C4FM Half Deviation AutoCal
Test the connection between the transceiver and the OS2 using the OS2's built-in local echo service (

)
Do you hear yourself back correctly?
