Quick Start -- For experienced digital mode users 3. Registration -- How to become a registered user 4. Using the MixWHelp System -- Finding Information! _________________________________________________________ MixW: Welcome _________________________________________________________ The Demo version of the MixW program is good for 15 days. For registration information please see Registration There are 5 sections in MixWHelp. This overview is Section 1. To download sections 2 - 5 please see: Using MixWHelp _________________________________________________________ MixW stands for a Mixture of different modes. MixW now fully supports CW, BPSK31, QPSK31, BPSK63 & 125, MFSK, RTTY, FSK31, Packet (HF and VHF including TCP/IP over AX25), Pactor RX/TX (TX requires TNC), Amtor (Sitor) TX/RX (No TNC needed), Hellschreiber, FAX (RX only), SSTV, THROB, and MT63. In addition to these built-in modes, new modes can be added to MixW using a facility called "External mode plugin support". The first example of a plugin mode was Olivia, which was included in the 2.16 release package. MixW also includes support for multimode TNCs for those preferring a hardware-based approach to the 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, QSO 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, file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 2 of 13 and an export of the contest log to the newly required Cabrillo format. The log will import and export CSV and ADIF files. MixW has support for printing custom QSL cards or labels. There is built in DX Cluster support either via Packet Radio or the internet. MixW does not require a TNC to operate. The only requirement is that you have a computer running Windows 9x, ME, NT, 2000, or XP operating system, and a compatible soundcard. If you are experienced with the sound card modes you can just go straight to the Quick Start . 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 headphone or line output. You will also need to provide for transmit keying by PTT or some other method. The following site is recommended for additional information about interfacing your radio with the computer. First go to: Understanding Soundcard Interfacing, by Ernie Mills, WM2U: http://www.qsl.net/wm2u/interface.html to get an overview of the subject. Then if you are a home brew ham, just get to work and build an interface. If you are an appliance type there are plenty of plug-and-play interfaces. Follow any of the links on Ernie Mills' site above, use your favorite search engine, or check amateur radio magazines for the latest information. _________________________________________________________ Note: The authors of the MixW software, Nick and Dennis, have introduced a soundcard interface device manufactured specifically for use with MixW. To learn more about the interface, called RigExpert , see Nick's website at: http://www.mixw.net _________________________________________________________ AND NOW A WORD FROM OUR SPONSORS For the latest MixW software and related information, visit the MixW websites at: http://www.mixw.net and http://mysite.verizon.net/jaffejim/ For the latest version of MixWHelp and related information, visit the MixWHelp website at: http://k6ix.net/MixW.html _________________________________________________________ MixWHelp by Scott Hill, K6IX with many thanks to the following contributors: Scott E Thile, K4SET Denis Nechitailov, UU9JDR Howard (Skip) Teller, KH6TY Richard B.

For the full MixWHelp suite see: Using MixWHelp If your station is already interfaced and configured for SoundCard digital software, and you're an experienced operator with the SoundCard digital modes, then all you need to do to get on the air with MixW is: Install the software Configure your Personal Data Configure your Transceiver PTT settings Review the commands for basic operation GOTA! (Get on the Air)! _________________________________________________________ Install the software: The program download is a self extracting installation file. You can choose any directory you would like, or use the default directory of C:\Program Files\MixW\ The extraction procedure will automatically install all the files MixW needs to run on your system. The most important files for you to know about are: MixW2.exe (the main program file) bands.ini (default band frequency information) contest.mc (contest macros) CmnData.dll (program information) cty.dat (antenna heading system) pfx.dat (prefix id file) Other files are automatically created by MixW which are: file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 4 of 13 MixW2.log (default log file - be sure to back up often! ) MixW2.ini (saves your configuration - back up often ) MixMacros.ini (default macro file created when you first modify a macro) As you learn to use new features of MixW you will create new files, particularly for your mode specific macros. These files will have a .mc or .ini extension. Be sure to back up all of your *.mc and *.ini files, as well as your .log files. Finally, if you have registered MixW, make a copy of your MixWReg1.dll file and paste it into your MixW folder. _________________________________________________________ NOTE: There are TWO DIFFERENT MENU LAYOUTS AVAILABLE IN MIXW. To use this help system your menus should look like this: MixWHelp uses ONLY LAYOUT 1. If your menu items are different than the ones shown above select: View | Menu and choose Layout 1. _________________________________________________________ Configure your Personal Data: Select Configure | Personal Data. This will display the following dialog box: file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 5 of 13 Enter your Station information and select your CW ID options, then click OK. (Your callsign should be in ALL CAPS). Configure your Transceiver PTT settings: _________________________________________________________ The authors of the MixW software, Nick and Dennis, have introduced a soundcard interface device manufactured specifically for use with MixW. For instructions on configuring and using this interface, called MixWRigExpert , see Nick's website at: http://www.mixw.net _________________________________________________________ If you are using VOX to trigger TX/RX function, and you are not using CAT features you can ignore this section entirely and go directly to the Commands for basic operation. If you are triggering TX/RX with a PTT circuit, or CAT control, you will need to configure MixW to key your transceiver. To do so Select: Configure | TRCVR CAT/PTT. This will display the following dialog box: file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 6 of 13 This dialog box is for the PTT and/or CAT features. If you will not be using the CAT function, set TRCVR to "None", ignore the rest of this dialog, and click on "Details" to configure your PTT COM port options. If you will be using CAT for PTT, first select your transceiver make and model from the drop down menus. (Note: if your model is not listed, try a similar model of the same make. For instance, almost all CAT capable Kenwoods work with the TS-850 setting). Next, check PTT via CAT command box, then click on "Details" to configure your CAT COM port options. Select the COM port you will be using. If you are using this port for PTT only, then only the COM port number and the RTS/DTR settings apply. If you are using this port for CAT PTT then set the port to match the requirements of your transceiver for CAT. file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 7 of 13 If you want to use one COM port for CAT and another for PTT, first configure the CAT/PTT port for CAT, then choose: Configure | Secondary PTT port | Port Settings to set the secondary COM port for PTT. _________________________________________________________ Commands for basic operation: Mode selection Select the mode you wish to operate by clicking Mode | your choice of mode: file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 8 of 13 Notice that the status bar will change according to the options and features specific to the mode you have selected, and the mode will be indicated in the mode box. For instance, IMD is only relevant in the PSK modes, while Connected or Disconnected is only relevant for the connected modes: You can also switch modes by clicking on the mode box in the status bar and selecting the mode you wish to operate from the pop up menu: file://C:\Users\S\AppData\Local\Temp\~hh3CD1.htm 9/14/2010 Overview of MixW Page 9 of 13 Switching between TX and RX: There are several ways to switch MixW between TX and RX. The Pause/Break key (on the computer keyboard) will toggle TX/RX.

  • Efficient Multi-Carrier Communication on the Digital Subscriber Loop
    Efficient Multi-Carrier Communication on the Digital Subscriber Loop Donnacha Daly Department of Electrical and Electronic Engineering Faculty of Engineering and Architecture University College Dublin National University of Ireland A thesis presented to the National University of Ireland Faculty of Engineering and Architecture in fulfillment of the requirements for the degree of Doctor of Philosophy May 2003 Research Supervisors: Dr. C. Heneghan Prof. A. D. Fagan Head of Department: Prof. T. Brazil Abstract This thesis explores three distinct philosophies for improving the efficiency of multi-carrier com- munication on the digital subscriber loop. The first topic discussed is impulse response shortening for discrete multitone transceivers. The minimum mean-squared error impulse response shortener is reformulated to allow near-optimal rate performance. It is demonstrated that the best existing eigen-filter designed channel shortener is a particular case of the proposed reformulation. An adap- tive time-domain LMS algorithm is provided as an alternative to eigen-decomposition. The next part of the thesis examines bit- and power- loading algorithms for multitone systems. The problem of rate-optimal loading has already been solved. It is shown, however, that the rate-optimal solu- tion does not give best value for complexity, and that near optimal schemes can perform very well at a fraction of the computational cost. The final section of the thesis is a brief exposition of the use of wavelet packets to achieve multi-carrier communication. It is proposed that the non-uniform spectral decomposition afforded by wavelet packet modulation allows reduced inter-symbol inter- ference effects in a dispersive channel.
