Perhaps someone in a local amateur radio club could lend a helping hand?

PDW Support / Re: where is the slicer driver?
« on: 10 Feb 2024, 07:21:06 »
The slicer driver is only used in Windows 98, Vista, XP and Windows 7 32 bits.
In PDW Interface Setup, select either Soundcard or RS232. The latter setting is for use with the USB interface.

PDW Support / Re: Help with PDW v3.12

From the FAQ:
'I use an SDR stick, but I don't get any or garbled text
Double check the SDR settings (frequency, gain). The recording settings of your soundcard are critical. There is no guarantee for success. For a 100% no-fuss result you should consider using a cheap second hand scanner in combination with one of the interfaces on this site.'

Normally, you shouldn't have to worry about the COM port settings, but the speed to the PC is 19200 8N1 as well.
You can use a serial port monitoring program to see the data sent to the PC.

I have added PDW Support (other languages) for those users who are fluent in e.g. German, French or Swedish but not in English.

I would try to connect a 10 uF capacitor to the 'hot' side of the volume potmeter.

Data Slicers and Interfaces / Re: Discriminator tap
« on: 18 Jul 2021, 17:13:00 »Hey most i have discriminator tap when i use usb interface😀
That's answered in the Frequently Asked Questions -
For error free monitoring of paging signals, you need a discriminator output in combination with an interface. Using an interface in combination with an earphone output is a waste of the investment. In that case, you're probably better off using the earphone output in combination with your PC's soundcard. A 4 level interface almost certainly won't work with an earphone output.

117.0.0.1 is not the IP address for mail.btinternet.com.
Are you sure it's not 127.0.0.1 (localhost)?

PDW Support / Re: PDW Signal lowering

If you start PDW, the signal indicator always starts at 95%. It then stabilizes to the actual signal quality. So, it's not PDW but the quality of your signal.
Please also check https://www.discriminator.nl/faq/index-en.html - 'Discriminator Outputs', Question 10 and https://www.discriminator.nl/paging/index-en.html - '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.'

PDW Support / Re: Logfiles not going where expected after move to Win10
« on: 09 Jan 2021, 15:02:43 »
It's a Windows 10 security mechanism that doesn't allow applications to write to the Program Files folder. A solution is to put PDW in a different folder. I use C:\Apps\PDW

The solution: improve the input signal.
For a detailed answer, you have to provide more information.
- What type of scanner do you use?
- Does it have a discriminator output?
- What type of signal are you monitoring?

Data Slicers and Interfaces / Re: FSK to USB Interface - resistor required??
« on: 22 May 2020, 10:15:55 »
The main reason for using a resistor is to protect the receiver IC in the scanner. From the FAQ -
'What's the function of the resistor?
Connecting or disconnecting an interface to the discriminator output might cause a short-circuit. The limiting resistor prevents the discriminator IC from being loaded or damaged. Further to that, it prevents your PC's microphone or line input from being overloaded.'

Try tweaking the sound input level. PDW is very sensitive to the right setting. Keep the scanner volume low, as ingress may occur from the earphone output to the discriminator output on the 3.5 mm socket.
Or consider buying a USB interface, which will save you a lot trial-and-error.
