I have a strange behaviour from my TBS 5922 USB receiever.
The first scan i do (with Crazyscan) comes back nicely.
The sceond one, even after just a few seconds, exhibits spikes in the graph - particularly for horizontals, and most markedly in the lower part of the Ku band.
First scan (19.2E):
Second scan (19.2E):
I have tried three different LNBs, two different dishes/cablings (dedicated 75cm, CM180 w. multiswitch), so I am fairly confident this is a receiver problem.
Once the spikes have set in, it is clear that tuning near the spikes gives noticably worse results.
Only thing left is to try USB extension cable to get the receiver away from the Computer, and if that doesn't work, use a different computer. (The computer is a massive high-frequency generator itself!)
Anybody seen anything like this before?
