VBCTone

This app is sound FFT and frequency measure, that is Morse-code decoder "Valiance Backbone for CW (VBC)"'s subset. So, if you had the VBC, you did not need this VBCTone. VBCTone is useful to detect call-back DX stations frequency. VBCTone is able to measured transceiver's CW pitch. Frequency resolution is ±5Hz. Preparing operation for FFT makes correct frequency and High resolution shape. Let's try it! This app contains these functions like bellow. tone zero-in/shift-in indicator / tone frequency measure(±5Hz) / sound level measure / peak search Operation movies are in www.youtube.com. http://goo.gl/yEu3d1 http://goo.gl/7gp4yw
