The program will NOT report a hit if the DESCRIPTION of any of the frequencies is identical. If two transmitters have exactly the same description, it assumes the two frequencies are different channels in the same transmitter and cannot both be on the air at the same time. Also if a radio is not duplex as a repeater, it cannot transmit and receive at the same time. So if the receiver has exactly the same description as a transmitter, it will not report a hit. For this purpose CASE IS SIGNIFICANT! WL7aml does NOT equal WL7AML.
Descriptions are limited to 8 characters. When modifying the two files of frequencies (RFREQS & TFREQS) keep exactly the same number of characters in the frequency and the description. It reads the column the character is in to determine the information. More that the maximum number of characters will bomb the program.
The frequency files, RFREQS and TFREQS, may be edited with any ASCII editor. One is included. To edit the receiver frequency file, type TED RFREQS. When you have finished entering or changing the data, press the F7 key, then ENTER. To edit the transmitter list, just substitute TFREQS in the above.
To run the program, type IM OUT. This will place the results of the run in a file name OUT. You may substitute any valid file name in place of OUT for different runs.
Several example results are included. These files have names consisting of a single digit such as 1, 2, 3, etc.
The program is written and compiled with Borland Turbo Pascal 3.0
