My Ham Radio Interests
Voice over PSK31 (VoPSK), Software Defined Radio (SDR), DSP, Narrowband TV (NBTV) over HF, and Independent Sideband (ISB) over HF (for simultaneous voice and video).

Voice over PSK31 (VoPSK) uses speech recognition software for transmitting, so that the keyboard is used only for editing errors in the speech-generated text. Text-to-speech (TTS) software is used for receiving, so that the operator can monitor the other station's transmission without watching the PC screen. Macros can be used with VoPSK, just as with keyboard-based PSK31. VoPSK is more spectrum-efficient than any other digital voice mode, and is permitted in any bandplan segment designated for PSK31 (including 30M).

For more information and software downloads, see my HamSDR page.
