Lots of errors with Fusion decoding. P25 works perfectly.

Just my opinion, but that noise spike in the marked attachment is likely not doing your decodes any good.
P.S.
Thinking about it being on a different colored trace might mean its not interfering like I think. I've not had much experience using DSDPlus, but I am working on it. :)

Im having the same issue. On all Fusion channels. I know the signal strength isnt great on the screen shot - but I get perfectly fine decoding on less with other protocols.
I will also send this to them to help out.

I think Fusion is a wider protocol. You should be using a BW of 12.5 or more -- at least I would. Any time I've monitored fusion, I used a looser filter (high bw setting).

And the signal you have is nearly abysmal. Yous houldn't expect anything to decode well (regardless of protocol) without at least a 20 dB SNR.

The signal is definitely horrible, yes-but I can get intelligible voice out of weaker signals with NXDN, DMR, P25, etc. So I do think that the Fusion decoding does have room for improvement - its definitely not as efficient with decoding weak signals as the other protocols [yet].
As for the bandwidth, I was just playing around with it, I tried it on all of the available bw settings and I just happened to take the screenshot as I was trying 9.5. I've never gotten half-rate decoding before either, that's new to me.
Decoding for signals with good strength doesn't seem to be an issue though
