To monitor paging signals, several options exist.
Option 1: PC with soundcardThis only works for 2-level signals. You'll need:
Under Windows XP and higher, fair to good results can be achieved, but success is not guaranteed. Both the quality and settings of the soundcard and the settings of PDW impact the performance. There is no standard recipe to receive paging with the soundcard. It's a matter of trial and error to find the best soundcard and PDW settings for your PC.
If you use a DVB-T stick, things get even more complicated, as you also have to finetune the frequency correction and gain. In many cases, using a DVB-T stick does not lead to a stable solution.
Option 2: Interface - USB or RS232You'll need:
Advantage of this configuration is that you don't have to tweak any soundcard settings. The USB interface also works on a PC without a serial port. The interfaces can only be used for 2-level modes (POCSAG 512, 1200 and 2400, Flex 1600 and Mobitex).
A built and tested USB or RS232 interface or the circuit board plus programmed microprocessor can be ordered through the Order Page.
Option 3: PC with a 'slicer' interfaceYou'll need:
Advantage of this configuration is that you don't have to tweak any soundcard settings. If you're running Windows XP, you have to install a driver for the serial port. This driver is included in the PDW zip file.
A 4 level interface can be ordered through the Order Page The 2 level interface has been discontinued.
Option 3 under Windows 95, 98 en MESometimes PDW doesn't work under Win9X. This may have to do with the serial port power management. The remedy is:
