    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I'm going to be traveling and would like to decode ACARS using my portable scanner Uniden BC125at and laptop running ACARSD software, I've tried in with limited success in the past, It seems like the microphone input level on computer and the volume on the scanner have to be just right Any suggestions on improving the decode rate?

Use line in, not microphone.

And also use a ground loop isolator between scanner and computer, or there will be audio distortion that will make decode more difficult and potentially damage the scanner.

If your laptop has a line-in jack, use it instead of the microphone jack. The microphone jacks are very, very sensitive to input signal levels and, as you found out, are very hard to get right. Line-in jacks are less sensitive. If you don't have a line-in jack, you may want to try a USB audio interface.

Edit: Sorry Jon, we were typing at the same time.

I've not used the ACARSD software, so I can't speak to it. May I sugget the PDW software for ACARS?

I have always had good results using PDW on Window XP. I am using Windows 10/64 now and I cant install the slicer driver that comes with the PDW. Any advice on how this might be done will be appreciated greatly. Thanks

Also don't use squelch - keep the squelch off, even tho you don't have any signal. There is a sync signal that's very fast, and many scanners simply won't open up fast enough to hear it. Without hearing that sync signal, no decoding occurs.
