PDW Support / Re: PDW email

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
« on: 10 Jan 2021, 20:00:20 »
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

Discriminator Outputs / Re: Favorite D-TAP Scanner for use with PDW
« on: 23 Nov 2020, 10:08:32 »
From the FAQ -
Can I connect the interface to my scanner's earphone output?
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.

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.

PDW Support / Re: Hmmm FSK to USB interface
« on: 05 Feb 2020, 20:13:35 »
Excellent. As mentioned in my email: If you zoom in to the manual, you will see that both switches are in the off position. To avoid confusion, as a double check the text ‘off-off’ has been added.
In the original POCSAG standard, the function bit is used to determine whether a message is numerical (POCSAG-1) or alphanumerical (POCSAG-4). However, many operators don't adhere to the standard. In that case, PDW makes a best guess. In 'Options - Options', you can select to display messages both numerical and alphanumerical.
Possibly by leaving out the 10k resistor, the interface or the scanner got overloaded, resulting in the wrong decoding in PDW.
The UBC355CLT looks like your UBC355XLT.

Ah, OK. The interfaces are for paging. For AIS, you need a soundcard. A cheap USB soundcard will do.

Data Slicers and Interfaces / Re: FSK to USB Interface Enclosure
« on: 16 Sep 2019, 07:39:15 »
Thank you Steve!
Sorry to see a declining use of paging systems in Australia. I still see added value over GSM/UMTS/LTE/5G, e.g. reliability and deep indoor coverage.

Data Slicers and Interfaces / FSK to USB Interface Enclosure
« on: 13 Sep 2019, 15:26:01 »Based on user requests, it has been a long cherished wish to realize a matching enclosure for the USB interface. With the recent purchase of a Prusa I3 MK3 3D printer, finally these requests can be accommodated.
The enclosure comes in 3 colors: black, red and silver. Quality PLA filament is used on a powder coated steel bed, which gives the enclosure a nice looking textured surface. The lid is mounted on the case by a snap-fit connection.
Prices and 'Buy Now' buttons for instant ordering can be found on the Order page.

After email contact, it appeared that the AR8600 detector output on pin 2 only is only enabled in NFM, while Geoff was using WFM for the pager signals. Mode changed and all working great.
