I am currently running DSDplus 1.101 - or the last freeware version avaialble.

My P25 phase I decoding sounds bad.
If I upgrade to Fastlane, will I notice any improvements in P25 phase I decoding?

I have an antenna on the roof, I have two rtlsdr dongles. I have a 3ghz quad core computer and get a good signal with less than 20% cpu usage and still the converstations are hard to follow because it sounds poor decoded.

Wondering if paying for DSD+ has improved decoding ability of p25phase1 audio?

If the P1 system is simulcast / using CQPSK modulation, I would say yes. It did for me.

I would think that 1.101 wouldn't be having issues with strong C4FM signals, so it sounds like you're dealing with CQPSK.

I'm in the same boat here. I have one LSM simulcast system here which doesn't decode properly. The other trunking channel I follow is C4FM which decodes perfectly. Curious if FastLane DSD+ fixes this. Worth a few bucks to me to have it working.
