Raymond, Programmers │ └─────────────────────────────────────────────────────────────────┘ Welcome to Slick Intermod Detector V2.6, This Intermod Detector is designed to run on any IBM/Clone PC/MS-DOS PC using V2.01 or later DOS. Although IMOD will run on any type clone, it is suggested to use a PC with a 10 mhz or better clock speed with math-coprocessor for faster processing. Of course the higher the CPU clock speed, the better the results will be in terms of fast calculations and results. INTERMOD DETECTOR is an easy use computer aided numerical analyzer tool for the Radio Communications System designer or user. Transmitter and receiver frequencies for a specific site are entered into the program and INTERMOD DETECTOR computes and displays the performance characteristics of the receivers under test related to the development of intermodulation as a function of the transmitters at the site. INTERMOD DETECTOR is an entirely menu driven spreadsheet like program which displays the offending transmitters as well as the offended receiver. A communications site, once established, may be saved to a disk file, and old sites may be recalled from the disk. Once a site has been loaded from the disk or from the keyboard, it may be modified at will in order to determine the system's performance with varying transmitter and, or receiver frequency values. The files generated INTERMOD DETECTOR are standard ASCII text files, and may be easily written or changed using most editors and word processors. INTERMOD DETECTOR computes results from using all combinations of the transmitters at the site including up the 9th order products and compares the results to the listed receiver frequencies. The general form of testing is: A+B+C, A+B C, A+B, and A INTERMOD DETECTOR is written in power basic and compiled into an executable run file requiring no additional software other than DOS. The Power Basic source code is available separately and if you purchase the source code, INTERMOD DETECTOR may be easily tailored to your specific technical requirements. ****************** You are hereby granted a limited license to use this software on a trial basic for 5 days. After this evaluation period, if you decide to continue using this product, you are required by law to register the program with the authors. ****************** The registered version is capable of testing triplet transmitters up to the ninth harmonic order with setable receiver passbands and unlimited receiver/transmitter frequencys in the site files. To get your registered copy with advanced powerful features send a check or money order for $295.00 to Simple Software Company, P.O.Box 8184, New Orleans, La. 70182. You will receive the latest version with printed documentation and a certificate for one future upgrade at 50% off. ------------------------------------------------------------------------------ Main Menu: ▒▒▒▒▒▒▄ ▒▒▄ ▒▒▒▒▄ ▒▒▒▒▒▒▄ ▒▒▄ ▒▒▄ ▒▒▄ ▒▒▄ ▒▒▒▒▒▒▄ ▒▒▒▒▒▒▄ ▒▒▒▒▒▒▄ ▒▒█▀▀▀▀ ▒▒█ ▒▒█▀ ▒▒█▀▀▀▀ ▒▒█ ▒▒█▀ ▒▒█▒▒▄▒▒█ ▒▒█▀▒▒█ ▒▒█▀▒▒█ ▒▒█▀▀▀▀ ▒▒▒▒▒▒▄ ▒▒█ ▒▒█ ▒▒█ ▒▒▒▒▒█▀ ▒▒█▒▒█▒▒█ ▒▒▒▒▒▒█ ▒▒▒▒▒▒█ ▒▒▒▒▄ ▀▀▀▒▒█ ▒▒█ ▒▒█ ▒▒█ ▒▒█▀▒▒█ ▒▒█▒▒█▒▒█ ▒▒█▀▒▒█ ▒▒█▒▒█▀ ▒▒█▀▀ ▒▒▒▒▒▒█ ▒▒▒▒▒▒▄ ▒▒▒▒█ ▒▒▒▒▒▒▄ ▒▒█ ▒▒█ ▒▒▒▒▒▒▒▒█ ▒▒█ ▒▒█ ▒▒█ ▒▒█ ▒▒▒▒▒▒▄ ▀▀▀▀▀▀ ▀▀▀▀▀▀ ▀▀▀▀ ▀▀▀▀▀▀ ▀▀ ▀▀ ▀▀▀▀▀▀▀▀ ▀▀ ▀▀ ▀▀ ▀▀ ▀▀▀▀▀▀ by G.M.

Example, let's assume one of your accounts is the Majesty Building. Enter "MAJESTY" as a site file name for both transmit and receive frequencies. The only limitation is keeping the name to within the DOS requirements of no more than (8) eight characters. See Selection #2 (N)ew, below. ------------------------------------------------------------------------------ ══════════════ARROWS-to-MOVE═══════ESC-EXIT══════ENTER-to-SELECT══════════════ LAKEWAY .RCV COASTAL .RCV TEST .RCV 71021952 Bytes free The above menu is displayed as a result of choosing option 1, 2 or 3 from the main menu. This menu selects the appropriate site frequency lists. The cursor keys move the highlight bar from file to file and the Enter Key is used to pick that highlighted selection. If you had not previously entered site locations, no matter whether you asked for Receivers or Transmitters, the menu will automatically switch to the opposite choice. I.E., if you started by choosing (R)ecivers, once the pick is made, the menu will, by default, switch to transmitters. ------------------------------------------------------------------------------ SELECTION #2: (N)ew Create (N)ew or (M)odify old File?

After entering your last frequency, hit the Enter key on a blank line to escape. ------------------------------------------------------------------------------ SELECTION #2: (M)odify Create (N)ew or (M)odify old File?

Screen 1 COASTAL.XMT COASTAL.RCV Xmit= 3 Recv= 5 464.62500 608.62500 865.51250 655.83750 440.62500 666.03750 697.51250 761.25000 Next, you will be offered a last minute option of adding additional frequencies to either column or saying "No" and continuing on...... Do you want to test Additional transmit Freq's (Y/N) -->n Do you want to test Additional receive Freq's (Y/N) -->n IMOD can be used to test up to the ninth (9th) order of harmonic combinations. Normal use is 3 with 7 being the highest practical value. The PassBand sets the upper and lower limit of the receivers bandpass. Example: Assume a frequency of 100 mhz. and a passband of .025mhz. This means any harmonic combination up to the order selected must fall between 99.075mhz and 100.025 in order to be considered a conflict for the 100mhz receiver. Use of the enter key here will by default, set no passband (0). Last, you are asked where you wish the output data to be piped. You have the option of the local monitor screen, the line printer connected to LPT1: (parallel port #1) or a ascii text file called CONFLICT.DAT Test up to what Harmonic (1-9) -->7 Test within +- what PassBand (.0125=12.5Khz) ? .025 Send Results to (S)creen, (F)ile or (P)rinter? -->▓ ------------------------------------------------------------------------------ Screen 2 A recap of the Sites and frequencies will be re-displayed along with some statistical data on the mid right side. This data takes one cycle of calculations to produce projections or estimates of remaining time, total calculations necessary, calculations done to the minute and the estimated completion in real clock time expressed in military hours and minutes.

This is reasonably intuitive and results will depend on what graphic color card is installed in your PC. The system comes up in monochrome to begin with and when this function is selected, a color configure file is created called COLORS.TXT, which stores the new colors that you have selected. Should you wish to return to monochrome, it's easier to just delete this file from the directory rather than to fumble through the color selections looking for all the black and white background - foreground settings. SELECT the area you want to change with the Up/Down arrows Use Grey PLUS to Change Letters Use Grey MINUS to Change Backgrounds. Hit the ESC key when you are finished.
