I have the samsung Tab II I hocked up the radio and tablet as described. When I turn in the KX3 companion I get a message No KX3 Detected. I set the baud rate and confirmed my cable is work with the Tab and KX3 Factory cable.
Thanks to you James. We are all sharing knowledge and I learned a lot in the past two years. WSPR is great for learning propagation and testing setups (particularly antennas). I actually have a process listening on 20m band (my preferred band for now) to check how propagation behaves during the day. Enjoy! 72/73 Andrea IU4APC
