All interfaces can be repaired at a reasonable price. It's always (much) cheaper than a new interface. I will send you an email with my address.

Unfortunately, I don't have matching plastic enclosures for my interfaces. You may wish to consider to put the interface in a cheap plastic soap box and drill the necessary holes.

Data Slicers and Interfaces / 4-Level Data Slicer Repair question
« Last post by zonian149 on 26 Jan 2019, 15:36:28 »
I have two 4-Level Data Slicers that I think are not working, At least I cannot get them to work anymore. What would it cost to send them in to get repaired or would I be better of just waiting for the next supply of Slicers that will be coming out in February? I would really like to get them repaired just to have as backups. Thanks for a great product. Is it possible that I may have damaged one of them by picking it up while it was running since it did not have a plastic case around it. If I order new ones, can they have plastic cases with them?

PDW Support / Re: I have some question about POCSAG decoding
« Last post by BH9DNV on 25 Nov 2018, 15:17:23 »
hi
I use POC32 to solve the problem. When I receiving the same signal, the PDW displays scrambled code or tone only, but POC32 can decode normally. I don't know what happenen, but I hope to upgrade the PDW again.

Hi,
Please provide details of your hardware connections/setup from the RTL-SDR to the PC - how are you connecting the RTL-SDR to the PC? Is it a discriminator output from the RTL-SDR?

I'm going to be offline for a couple of weeks so hopefully someone else will be able to assist you in the meantime.

Suggest you have a good look through Rene's discriminators.nl site and the PDW documentation as well.

Cheers
...Steve

Thank you for your reply to my message:
For the signals from trains,I can tell you some details
Frequency:821.2375MHz
Coding mode?POCSAG
Rate:1200bps
Data transmission mode: synchronous data transmission mode.
=======================================
When someone else's computer receives and decodes
The content displayed by PDW is ?POCSAG-2 NUMERIC 1200 XXXXX XXX XXXXX?XXX means only the right number of messages
=======================================
In my computer
When i received the signal,Only POCSAG1200 will be displayed above the PDW software.
nothing has been decoded.I don't know what's going on.Maybe there's something wrong with RTL-SDR.

Hi,
Can you provide more information of your configuration? eg for most reliable decoding you should use  discriminator tap and the USB interface. Radio signal strength is also a factor if the source is moving.

I have no knowledge of RTL-SDR, so that could be an unknown factor.

Cheers

PDW Support / I have some question about POCSAG decoding
« Last post by BH9DNV on 22 Nov 2018, 15:12:49 »
Hi everyone:
I have some questions about POCSAG decoding. Our country's railways and high-speed railways have a device that uses POCSAG to pass their position to ensure the safety of railway workers. Similar to the ADS-B of a civil aircraft, I use RTL-SDR to receive and use PDW. 3.2b01 decoding, but my computer can not decode, I can try it on other people's computer, the detailed parameter of decoding success is ?POCSAG-2 NUMERIC 1200?, if anyone can help me, please contact me thank you!

I'd really rather attempt to do the discriminator tap myself but I don't know what to do. I am using a Bearcat BC700a scanner and its pretty easy to take off covers and get inside with room to work. Is there a site that has information on everything involved with doing this modification to any particular scanner?
