FSK decoder for PDW

NO LONGER AVAILABLE!


Hi all,
Please take a look at my latest creation.
Cost is $49. Postage within Australia is $9.

PM me if you need to know more.

This is a 2-level FSK decoder.
It plugs into your PC's 9-pin serial port (COM 1) and a suitable receiver via 3.5mm mono plug.
It will only run under Windows XP. You will also need PDW software (available free on the net or I can supply).

I can supply a decoder to connect to a headphone/speaker output OR via a discriminator tap on your scanner/receiver.
Please specify which version you want.
The two versions look identical, a couple of components are changed internally.

These units are built and tested by myself (a radio/electronics tech with 30 years experience).

Is there any difference between using one of these and the sterio/mono ? cables ? or is it just the other way of doing it ?

The data is generally completely error-free when you use a decoder.
Using the soundcard with either a mono or stereo cable works well, but can be tricky to set up. And, it ties your soundcard up too.

Shame there is no way you couldn't fit inline with a USB connection or something similar as some computers (especially laptops) nowdays don't have a serial connection

looks great as I would like to free up the soundcard however I can't find anything suitable for my laptops

No, it's not designed for USB.
I don't think a USB to Serial adaptor works either, unfortunately.

Probably is this your solution;

RS-232 Interface and atleast PDW version 3.0, to make it work.

Hi all,
I am no longer building these decoders. Most PC's don't have a serial port anymore, plus I simply don't have the time these days.
