RMS Express WINMOR Peer-To-Peer Sound Card Setup RMS Express WINMOR Peer-to-Peer Sound Card Setup RMS EXPRESS P2P provides fast, reliable, error free ARQ messaging directly between two stations, bypassing the Winlink system’s infrastructure. Operation is fully automatic in both directions once a connection (handshake) is achieved. This method permits discrete, error free local message transfer with attachments (ICS-213, Flmsg files, etc.) even if the Internet has failed or long-range RMS HF stations are unavailable due to poor propagation. Further, the receiving station need not be manned as long as it is listening for a connection on an agreed upon frequency. If not already installed, download the RMS Express sound card program at, www.winlink.org/ClientSoftware and follow their instructions for installation and initial setup. These P2P Quick-start instructions assume the use of a Signalink USB sound card interface, so setup and adjustment procedures may vary slightly for other interfaces. After coordinating a Peer- to- Peer session with another station, follow these instructions: 1. Open RMS Express. Choose Winmor P2P in the Open Session drop-down box. 2. Click on either New Message button to open a blank form. Check that the Peer-To-Peer Message button is selected. Only one call sign may be entered in the To box when using P2P. Click on Post to Outbox after composing message. 3. Click on Open Session (Fig. 4) and then on Setup (Fig. 5) in the session window that opens. Select Winmor TNC Setup from the drop-down setup menu. (Observe that the WINMOR Sound Card TNC window also opened on your screen) Just as with Fldigi, select USB Audio CODEC for both the capture and playback device. Select 1600 for your inbound session bandwidth. Click on the Update button. (If you have a different sound card interface, this selection may vary.) 4. Go back to the Setup drop-down box and click on Radio Set-up. Select Manual or a specific radio from the drop-down menu, then USB, USB Digital, or FM as appropriate. Select the appropriate USB Radio Control Port if in use or None, and the PTT Port to External if needed. Click Update, then Close. (Look up the USB port number in your computer’s Hardware Profile screen.) 5. Return to the Setup drop-down box and perform Transmit Level Tests with the Peer Station. Adjust your Signalink TX settings based on the ALC indicator on your radio and the Peer Station’s signal reports. (Turn up the mic gain until the ALC meter indicates, then back it off just until it disappears.) Adjust the Winmor TNC Rcv Level by tuning the RX knob of your Signalink while the peer station performs his transmit level test. Levels should be in the green region. 6. Enter the other station’s Call Sign, the Center Freq and Dial Freq. The center frequency must be set exactly 1500 Hz above the dial frequency. 7. Click the Start button. Observe the Rcv Level and adjust your Signalink until a “handshake” is achieved and the two stations begin interacting automatically. 8. Check your Inbox and Outbox. Look for attachments. Make note of your settings for future sessions. Winmor is an HF digital sound-card mode designed primarily for use with the Winlink 2000 radio- email network. Winmor provides an alternative to expensive PACTOR hardware modems at speeds between Pactor 1 and 2. Winmor, the Winmor software modem, and the RMS Express application were developed by Rick Muething, KN6KB and Vic Poor, W5SMM. The Winmor modem includes innovative features such as a “busy frequency” detector to reduce potential interference. While the software itself is free, a registration donation supports ongoing development by the non- profit Amateur Radio Safety Foundation, operator of the Winlink 2000 system. Registration also removes the initial start-up reminder and permits automatic software updates via the Internet. Hawaii ARES would like to express its gratitude for the preceding article, which was contributed by Eric Lougee (KB1OKX) and edited by Dave Colter WA1ZCN for NH-ARES. .

  • The FCC Filing
    Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC.

  • I William G Radicic, Amateur Radio Call Sign NS0A, Extra Class, License
    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.

  • RTTY Contesting
    Contents Foreword Chapter 1: Let’s Build an HF Digital Station An HF digital station boils down to three essential pieces: a radio, a computer and a device that ties them together. Chapter 2: PSK31 Get started with the most popular HF digital operating mode today. Chapter 3: RTTY RTTY may be an old operating mode, but it’s still the champ when it comes to contesting and DX hunting. Chapter 4: JT65 You’ll be astonished at how low you can go with JT65. High power and big antennas are definitely not required! Chapter 5: MFSK and Olivia With these two modes you’ll still be chatting when all the others have given up. Chapter 6: PACTOR When your message absolutely must get through error free, PACTOR is a great way to go. Appendix: Helpful articles from the pages of QST magazine Foreword Interest in amateur HF digital communications is growing at a rapid rate. On any given day, even when propagation conditions are poor and the bands are practically “closed,” you can hear the sounds of digital conversations taking place. The fact that most amateurs own computers is part of what is driving the popularity of HF digital. The other major factor is that so many hams live in homes that suffer severe restrictions on the kinds of outdoor antennas that can be installed – if any. Digital modes allow these amateurs to communicate with low power and compromiseD antennas, letting them enjoy Amateur Radio when they’d otherwise be off the air entirely. The only problem is that HF digital technology is a foreign concept to a substantial number of operators.

    6143 Anchor Lane, Rockledge, FL 32955 • arsfi.org Chairman Ajit Pai March 30, 2019 CTO Eric Burger Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Subject: Ex-parte Comments on Docket 16-239, RM-11828, RM-11708; Response to Prof. Theodore Rappaport’s letter to FCC Officials of March 20, 2019; Request for ex- parte meeting. Dear Chairman Pai, Mr. Burger, and FCC Officials: I am writing again on behalf of the Board of Directors of the Amateur Radio Safety Foundation, Inc., this time in response to the letter sent to FCC officials by Professor Theodore Rappaport on March 20, this year. Professor Rappaport continues to lobby the FCC, Congress, the Press, and the Amateur Radio community to have the FCC declare certain digital modes illegal and remove them from the HF amateur bands. He directly charges the Winlink Global Radio Email system and ARSFI’s Directors with impropriety, not fostering goodwill, conspiracy, fraud, improper pecuniary interests, corporate enrichment, intense radio interference, intent to obscure communications by encryption, operating a commercial service on amateur-allocated bands, fostering a danger to national security, even, outrageously, control of the FCC by “a tiny fringe of the hobby” (Winlink developers, users, sysops, and ARSFI). The ARSFI Board of Directors encourages the FCC or Congress to fully investigate these matters. We look forward to offering our full cooperation and demonstrating our transparency and openness. Request for an Ex-Parte Meeting We formally request an ex-parte meeting with the Commission to defend our position and correct the record. Since Rappaport was allowed an ex-parte meeting in the summer of 2016 with OET and WTB, where he claimed incorrect technical assertions about the Winlink system and its participants, and given the close association he enjoys with certain Commission officials, Commissioners, and employees, it is fair that our organization be given an opportunity to debunk his assertions in person.

  • WINLINK Radio-Only for the Traffic Handler by Gordon Gibby KX4Z This Article Is Designed to Assist the Nation's Amateur Radio T
    WINLINK Radio-Only For the Traffic Handler by Gordon Gibby KX4Z This article is designed to assist the nation's amateur radio traffic handlers in taking advantage of the radio-only capabilities of HF WINLINK gateway stations---without any usage of the Internet at all-- in the furtherance of traffic passage. The nation's cadre of trained traffic handlers represents a valuable emergency and public service resource in the event of a massive regional or national communications outage. There are now multiple known possibile scenarios for just such an emergency. So bolstering and furthering the traffic capabilities of the nation's amateurs is a worthy goal. While the traditional modus operandi of the WINLINK sytem is to move traffic (typically by HF radio) completely OUT of an area bereft of internet resources (whether at sea or on land) and then utilize remaining Internet operability to push the traffic to the actual email address of the desired recipient, the RADIO ONLY system is completely different and completely independent of the Internet. The Radio-Only system is a slightly quirky and completely independent system, which Mike Burton took pains to try and teach me. It offers significant flexibility to amateurs who are unable to make traffic schedules because of skip zones and propagation difficulties, due to its ability to relay traffic (emails, or emails with attachments of any kind including radiograms) hopskotching from automated station to another until reaching the desired point of pickup. Message Pickup Stations (MPS)--- that's a key feature of the Radio Only system. Because it never uses the internet, recipients CAN NOT pick up their messages by normal internet email.

  • Winlink By: W8XG Brent Parker
    Winlink www.winlink.org by: W8XG Brent Parker What is Winlink? Winlink is email for hams. RMS Express is our preferred software choice on our computer. It’s a windows based program and available at: www.winlink.org . There are many other usable software choices, but RMS Express has the most features and compatibility in one package. www.winlink.org is an excellent source for both information and free downloading of the software, but can be overwhelming, to a new user. This is Sarasota Digital’s attempt to simplify and expedite the new user in getting up and running with RMS Express quickly. There are great links to tutorials on the web, many of which are YouTube videos, but they are scattered all over. Our group has been thru this learning curve and compiled this document with links to this training. Winlink is a system of servers, accessed both via radio and the internet for moving email around the world. Winlink, while it is linked to the internet, was developed for transmission of packets (email) via radios. All email whether send over a radio or on the internet, is actually send in chunks (packets, hence the early tag of “packet radio”). When the receive station gets a successful packet, it’s acknowledged, and the sending station then sends the next packet. On the internet it’s very, very fast (and silent). On a radio, you can turn the volume up and listen to the packets being sent. If you were involved in computers in the 80’s, and had 1200 baud or even 9600 baud modems, you’ll be right at home! You’ll hear a lot of new terms, packet, pactor, winmor, telnet, TNC, soundcards etc.

  • DIGITAL COMMUNICATIONS (Part 4) by AD5XJ Ken
    DIGITAL COMMUNICATIONS (part 4) by AD5XJ Ken Disclaimer: These are my comments on digital communications and are not necessarily all there is to know on the subject. As with everything computer related – there are at least six ways to do the same thing. Given this caveat, let me say this is opinion and not the complete story. I only relate to you my experience of 5 or more years using digital modes and as SATERN Digital Net Manager to give you the benefit of my experience. I will leave the rest for you to research as you see fit. MT63 MT63 is a text only digital radio modulation mode for use in high noise/high reliability situations. It was developed by Pawel Jalocha, SP9VRC. MT63 is perhaps the most elaborate user of error correction techniques of all ham radio public digital modes. It uses a very efficient error correction method that uses character redundant sequences over several data packets. It has 64 tones spaced 15.625Hz apart, in the 1kHz bandwidth. It is so efficient that even if 25% of the character sent is obliterated, it will give perfect copy. This method of spreading characters from multiple words over several packets is known generally as Forward Error Correcting. The FEC error correction employed by MT63 uses a Walsh function that spreads the data bits of each character across all 64 of the tones of the signal spectrum and simultaneously repeats the information over a period of 64 symbols (at maximum interleave) within any one tone. This takes 6.4 seconds.

  • Inconvenient Truths About WINLINK & FLDGI/FLMSG
    Inconvenient Truths About WINLINK & FLDGI/FLMSG: Disclosure of Experimental Findings, Advanced Developments, and Discussions September 19, 2019 Gordon L. Gibby MD 15216 NW 41 Ave Newberry FL 32669 EXECUTIVE SUMMARY Although RM-11831 specifically addressed techniques rather than systems, as has been pointed out repeatedly by its author, the debate was obviously broadened to include systems, specifically the WINLINK messaging system, by multiple filers, some of whom claimed to be experts. The WINLINK team was not in any way arrogant to presume they were being assailed. Provably false assertions were repeatedly made, which any expert with a knowledge of radio and history would have easily recognized as false. Anecdotal claims were advanced repeatedly. False assertions of "encryption" or the pseudo-term "effective encryption" were bandied about, and multiple harsh demands were levied. Assertions of UN-enforceability or the impossibility of self-policing were loudly asserted. Nevertheless, the goal of openness in Amateur Radio was a laudable target, to which the WINLINK Development Team responded with the first open, networked, distributed, free receiver system, even including a 21-day rolling history, with easy ways to flag objectionable material and a well-oiled administative system manned by dedicated volunteers to process such reports.1 I have made such reports, and I have watched this self-policing system operate. The result was an astonishing two orders of magnitude objectively-measured drop in objectionable material, demolishing any claim of lack of enforceability or inability of self-policing. The critics of WINLINK earned well-deserved praise for their participation in developing techniques to catch those violating the very stiff Terms of the WINLINK system in my writings.
