2 天之前 · DOS Freeware popular program for ham radio communications, supports reception and transmission of radio teletype RTTY, AMTOR ARQ/FEC, SITOR A/B, NAVTEX and Morse code (CW) signals. A decoder for SHIP and SYNOP reports from weather stations is also included. This program is discontinued and unsupported. Originally developped by Schroeder DL5YEC.

RTTY.COM has been established to focus on the many aspects of Amateur Radio Teletype (RTTY) and to present to the dedicated RTTYer, and to the curious, a location wherein one can find information relating to RTTY and BAUDOT communications.

Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. [1] .

RTTY software, Digital mode ham radio - AMTOR, PSK31, AX25 ... A program for amateur radio digital communications via a sound card. Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), PSK31 (BPSK and QPSK), BPSK63, QPSK63, BPSK125, AMTOR-FEC (SITOR-B, NAVTEX), MultiFSK-16, MultiFSK-8.

Everyday more and more Amateur Radio operators are operating on the HF digital modes, in particular, RTTY. In each RTTY contest I operate, I find about 8-10% new calls that I've not seen before. There are several reasons for wanting to be a RTTY op.

2016年1月19日 · To decode RTTY signals you’ll need a shortwave receiver with a BFO (Beat Frequency Oscillator), a way to pipe your radio’s audio into your computer’s sound card, and decoding software. There are several RTTY software packages out there, free, and my favorite is MMTTY. More info on MMTTY is at: http://hamsoft.ca/pages/mmtty.php .

RTTY是业余无线电界最早出现的数据通讯方式，它大约是在二次大战期间，将原本用于有线电传打字的技术转移到无线电来传输文字，战后业余无线电人员就利用一些汰换下来的装备开始进行业余的通讯。 电传打字机 是一部极为昂贵且笨重的设备，它主要是由复杂的机械结构以及继电器等组成。 初期能够进行这种通讯方式的人很少。 随着电子以及计算机技术的发展，后来已经利用 数据 编解码器 与电脑结合来进行数据通讯。 时至今日，音效卡已经是个人电脑基本配备，只要 …

RTTY is a fun mode and easy to operate, but there are some questions every newcomer has. Please take a moment to read the following and much of the mystery will disappear. A RTTY transmitter sends out a carrier that shifts back and forth between two frequencies. There is no amplitude modulation, only a pure carrier which shifts frequency.

2023年8月23日 · RTTY (Also known as Baudot or ITA2) uses the Baudot 5-bit alphabet with FSK to send text messages over the shortwave. This mode is gradually dying out in favor of more robust modes like PSK31 in the amateur service. Uses the ITA-2 alphabet (Commonly known as Baudot, derived from the Murray code).
