Help files by Scott E. Thile, K4SET The Demo version is good for 15 days, for registration information please see Registration MixW stands for a Mixture of different modes. With this release of Version 2.02, MixW now fully supports CW, BPSK31, QPSK31, MFSK, RTTY, FSK31, Packet (HF and VHF), Pactor RX/TX (TX requires TNC), Amtor (Sitor) TX/RX (No TNC needed), Hellschreiber, FAX (RX only), SSTV, THROB, and MT63. Nick is constantly adding new modes and features to MixW, and strives to make it the best and most complete sound card digital mode program available. It now also includes support for multimode TNCs, for Pactor transmit, and for those preferring a hardware-based approach to the other digital modes. Even more modes can be accessed by configuring MixW to call other software packages from within MixW. Other MixW features include a voice keyer for SSB, FM, and AM phone modes. Excellent logging, sked scheduling and reminding, and even auto CQing of scheduled events through the fully configurable MACROS. There is also a sophisticated contest mode facilitating competitive digital mode contest operation, and an export of the contest log to the newly required Cabrillo format. The log will also import and export CSV and ADIF files. MixW also has support for printing of custom QSL cards or labels. There is also built in DX Cluster support either via Packet Radio or the internet. New! TCP/IP over AX.25 packet radio protocol is also supported now! Click TCP/IP for details. MixW does not require a TNC to operate. The only requirement is that you have a computer running the Windows 9x, ME, NT, 2000, and XP operating system, and a compatible soundcard. Click here for the minimum system requirements. System Requirements If you're experienced with other SoundCard Digital mode software, or upgrading from previous MixW releases, you may wish to start with the Quick Start to familiarize yourself with this exciting new release, and get on the air quickly. If you are new to SoundCard Digital mode operation, you will need to connect your radio's transmit and receive audio to your computer soundcard via the mic or line input, and the speaker or headphone output. TX/RX switching can be handled either by using your radio's VOX circuit, or by building a simple PTT interface. This is covered in Basic Set Up To configure MixW for your station and operating styles see Configuration See Logging for additional information about MixW's new logging and QSL features and operation.

    The Tarzan Series of Edgar Rice Burroughs

    I The Tarzan Series of Edgar Rice Burroughs: Lost Races and Racism in American Popular Culture James R. Nesteby Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree in Doctor of Philosophy August 1978 Approved: © 1978 JAMES RONALD NESTEBY ALL RIGHTS RESERVED ¡ ¡ in Abstract The Tarzan series of Edgar Rice Burroughs (1875-1950), beginning with the All-Story serialization in 1912 of Tarzan of the Apes (1914 book), reveals deepseated racism in the popular imagination of early twentieth-century American culture. The fictional fantasies of lost races like that ruled by La of Opar (or Atlantis) are interwoven with the realities of racism, particularly toward Afro-Americans and black Africans. In analyzing popular culture, Stith Thompson's Motif-Index of Folk-Literature (1932) and John G. Cawelti's Adventure, Mystery, and Romance (1976) are utilized for their indexing and formula concepts. The groundwork for examining explanations of American culture which occur in Burroughs' science fantasies about Tarzan is provided by Ray R. Browne, publisher of The Journal of Popular Culture and The Journal of American Culture, and by Gene Wise, author of American Historical Explanations (1973). The lost race tradition and its relationship to racism in American popular fiction is explored through the inner earth motif popularized by John Cleves Symmes' Symzonla: A Voyage of Discovery (1820) and Edgar Allan Poe's The narrative of A. Gordon Pym (1838); Burroughs frequently uses the motif in his perennially popular romances of adventure which have made Tarzan of the Apes (Lord Greystoke) an ubiquitous feature of American culture.

    I William G Radicic, amateur radio call sign NS0A, Extra class, license - endorse the position of the Members of this Board of Directors who unanimously are in support of the Commission’s proposal and encourage the elimination of the outdated and symbol rate limits. Opponents to WD Docket No. 16-239 have responded to internet and social media campaigns led by Theodore Rappaport, resulting in a multitude of comments that echo false or misleading technical points, driven by highly emotional arguments about “national security, crime and terrorism”. We address these arguments with the documented realities of science and logic in hopes that the Commission will find them balanced, informed, and trustworthy counterpoints for good decision making. The HF Symbol Rate Limitation in § 97.307(3) Should be Removed The current 300 baud symbol rate limitation was instituted around 1980 by the Commission as a mechanism to manage HF digital modes (both FEC and ARQ) that would be compatible with typical HF signal widths in use. The most common amateur HF digital modes in use then were AMTOR (similar to SITOR), later refined as Pactor 1 and HF packet (300 baud FSK). Since then, technical advancements in modulation, coding technology and Digital Signal Processing (DSP) now make it possible to implement significantly faster, more robust digital protocols with better spectrum efficiency (e.g. PSK31/63, MT63, Pactor 2, Pactor 3, WINMOR, ARDOP, VARA, Pactor 4, and other popular amateur modes). These modes are possible and affordable due primarily to the significant advancements in digital signal processing, cost reductions in computers, sound cards, and DSP processing chips since the original 300 baud symbol rate restriction was instituted.

  • Digital Modes RTTY

    Digital Modes RTTY

    Digital Modes RTTY Digital communication modes represent one of the fastest growing areas of interest in amateur radio, with the past decade seeing many developments. While there are other digital modes that radio amateurs are experimenting with, RTTY, AMTOR, and Packet Radio are the main digital modes on amateur radio. Newer modes such as GTOR are also emerging as amateur radio continues to develop in the area of digital communications. Baudot code is still the common denominator of digital modes, but it is far from standardised itself. While many use the term Baudot Code, others use the term Murray Code. These two names acknowledge two important telegraph pioneers, both of whom made major contributions in this field, however the correct term is CCITT International Alphabet No. 2. The differences between in practical systems is apparent in the punctuation characters and would not be noticed between two operators unless they used punctuation such as ! : % @ etc. Baudot is sent at differing speeds in different areas. Most US operation is at 45.45 baud (a hangover from a speed limitation by the FCC of 60 wpm for any coded operation), at 45 baud in Europe, while all operation in New Zealand is at 50 baud (after a collective decision to standardise to the commercial speed). Nowadays, computers have almost completely taken over from the mechanical teleprinter, so baud rate changes are no longer the problem they once were. ASCII This is used to a very small degree on amateur bands. The proliferation of personal computers in the ham shack, often with in–built communications facilities designed to work on telephone networks, encourages this mode, however there are much more practical ways to use a computer on the air.
