Hello Dieter,

While building my new drone station I discovered something odd.
With all new bought modules there is one which doesn't work properly, an A143-4.
Now I already own two of them so I compared them with the same (factory) settings, al jumpers in place except for the busCV jumper which I took out.
With all pots ccw and in LFO mode I slowly turn up the frequency on channel 1.
There is a big difference between the two modules, one will fully CW in a rather high speed, the other (faulty ) is probably only half that speed.
In VCO modus this is about the same, the good module goes really high (as it should) the other one stays at medium frequency.
The only way to get a really high frequency is by putting the common pot cw.
I tried al channels and checked all jumpers but I don't know what this problem is.
Please help.

Best regards
