TX sound frequency is changed if right mouse button is used or 'Ctrl' key is pressed. These screen buttons can be used for TX frequency changing also. ' Alt-Down' keystroke and ' >' button move RX frequency to 5 Hz up. ' Alt-', ' Alt-Right' keystrokes and ' >' button move RX frequency to 1 Hz up. You can use keyboard and screen buttons located below spectrogram ruler for fine tuning. RX and TX frequencies and shifts are also shown in the status line. Ruler under top window shows frequencies of sound spectrum. To change the TX frequency, click on the desired frequency by right mouse button (or the left mouse button with 'Ctrl' key pressed). In PSK modes you see only one TX frequency. The short thick black lines show TX frequencies.

In MultiFSK mode mouse click defines lowest radio frequency, not center one. To change the center frequency, click on the desired frequency (probably between the peaks). In most modes you see two vertical line in PSK modes - only one. The vertical red lines in this window show the working frequencies of the RX filters. In the top window the current spectrum of a signal (blue line) and a peak detector of spectral components (green line) are shown. The working area of the program is divided into several windows, the sizes of which can be changed by the user by dragging the borders.

It is fast and convenient to use with many macros for transmitting. A simple circuit for PTT-control can be used. You only need a transceiver and computer ( Pentium-100 or better) with a sound card. SELFEC SITOR, AMTOR-ARQ (SITOR-A) and DTMF-code decoding is also possible. HF-PACKET and UHF-PACKET (AX25) are supported in KISS-TNC emulation mode. PSK31 (BPSK and QPSK), BPSK63, QPSK63, BPSK125, AMTOR-FEC (SITOR-B, NAVTEX), Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), Simple software to handle devices connected to LPT portĪ program for amateur radio digital communications via a sound card.

A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club RTTY software, Digital mode ham radio - AMTOR, PSK31, AX25.
