The idea of a smartphone-based transceiver sounds excellent. I would prefer this over a cross-band solution in many ways. My Kenwood TH-D72A is slowly falling to bits and whilst I've contemplated a replacement: there's nothing really compelling out there. This more open hand-held design I think is a step in the right direction. Just needs a 70cm band PA (which is easy enough to achieve with a kit). One thought though, with the battery life of modern phones these days, I'd suggest maybe including the ability to power the phone as well from the radio's battery might be worthwhile. Whilst tethered, you could then turn off WiFi and just use CDC-Ethernet to communicate between radio and phone which would further reduce power consumption. When used in areas with no cellular communications, the phone could be put in "flight mode" to avoid wasting power on running a 3G/4G/LTE radio that's not useful. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
