# HG changeset patch # User Michael Wagner michael.wagner@gmx.at # Date 1474652598 -7200 # Fri Sep 23 19:43:18 2016 +0200 # Node ID 0e35f539fc38800907e088ab95d9d3a6c0071748 # Parent 1f9ff67ec2cdfe4ba55cb98fb741be712f3ebaf6 [btech] Delay writes statically, to avoid invalid header-response from KT-8900. Fixes #3993 Much simpler approch to ommit the "0x05"-Respone-Bug on KT-8900 (and other radios) mostly on linux. Instead of detecting platform or only delaying only on case of previous errors, the write is now always delayd. Result of following thread: http://intrepid.danplanet.com/pipermail/chirp_devel/2016-September/004264.ht... 73, OE4AMW
