3. The purpose of making the source code available is 1 To broaden the scope of the development of the new funtions and 2 TO make them available to the SWL community faster 3 To give users having programming facilities the possibility to adapt the programs to their personal needs 4 To give the possibility to port it partly to other receivers to other programming languages and or to other operating systems I invite everybody having programming facilities and interested in the development of HF receiver control programs to drop me an E mail to get the source code 2 Installation of program and set up In this part is described how the receiver should be connected to the computer which files you need in what directory structure these files have to be placed and an easy way to install the program and select the right set up 2 1 Connection between Receiver and Computer Before the program can be used the receiver should be connected to a serial port of a computer Dependent on which receiver you have you need different connector types For the PC a 25 pin or 9 pin serial connector is needed Details for each receiver are described in the next paragraphs In case your PC does not have a free serial port you can also use an USB port in combination with a USB to Serial convertor Most but not all of the USB to Serial connectors will work You better prevent buying those that do not implement the full RS232 protocol 2 1 1 Connecti
