6400 Baud FLEX PDW Poor Decode

[CanesFan95]

Using SDR# 1727 with PDW v1.32 and an Airspy Mini. 929-932 MHz FLEX decode on 1600 or 3200 baud is pretty good. But 6400 baud gets a lot of garbled/missed decodes. Been that way for years even with a good strong signal. Tried everything with the settings, Windows 10 audio, SDR# bandwidth. You name it, nothing works. Any advice for better 6400 baud decode? Thanks.

First off, grab a more recent version of PDW. Assuming you're using VB-Audio or similar to pipe to PDW?

Yes, I use Cable VB Audio. And I made a typo. I'm on PDW v3.12, sorry.

So, what does it mean if you see something like this:



Is that a bad decode or encryption?

Encryption. If your decode was bad you'd see random different colored characters representing decoding errors:
