Knucker won't do 125ks

Post by PE5PVB » Sun Sep 18, 2022 9:09 am

Hi,

We build two Knuckers. All ok, but we can't get it to work on 125ks/s symbolrate with the Portsdown 4. Are we missing something?

Does the Knucker do 125 ks/s ? Remember it is DVB-T only. Lower rates will take a long time to lock up so have patience.

Lowest we could decode was 150ks which was reliable (140ks 125ks wouldn't go)
Don't think this has changed.
Try testing at 150ks

PLEASE always read the BATC wiki before posting questions on the forum.

The specification on this page - https://wiki.batc.org.uk/Knucker#Hardware - says 150ks to 2MS

Thanks. Sorry, I checked the website, but did it too fast. I thought it said 125, but it's 150 :D
