Up thread there is a report of PC8 spiking on a Tacx Neo trainer. Maybe it is a third-party ANT+ PM issue? Or maybe just broken units?

I have a PC8.

So I wrote a javascript to detect and remove the spikes from activity .fit files, while leaving the rest of the data unmodified. Each spike is replaced by the 5s median power.
NP and TSS on my segments and rides go down by 1 or 2 watts/TSS.
The chart shows example of an 8 minute climb segment, with the original and despiked data.

The following forum is related to SRM PC8 and associated firmware development.

The GPS inaccuracy is across all PC8s. It's GPS implementation is rubbish.mds wrote:
It could be the problems are specific to my units. I am still investigating.

How is your PC8 screen contrast during sunny mornings and afternoons?
In these conditions with sunglasses I find that my is PC8 a bit hard to read (eg low contrast). I actually think my PC7 had higher contrast.

Here is a photo of my PC8 in morning light, along with a Garmin 500 and iPhone 7.
Do you think the PC8 screen is working correctly?
I need more contrast, especially with sunglasses.
