I keep getting continuity errors with certain frequencies but not with others, I can't find any pattern for this.

e.g

/opt/bin/mediaclient -m DVBS2 -f 12343500 -M QPSK -S 29500000 -V H -E 3/4
Using device: /dev/dvb/adapter0/frontend0
Setting DVB-S/S2 tune Parameters
using HI/LO Band frequency: 12343500
Modulation: QPSK (DVB-S)
Symbolrate: 29500000
Voltage: 18 Volt (Horizontal)
FEC: 3/4
Tone ON
Frequency: 1743500
Syntax OK
Checking for lock:
..........

gives an readout of this

But sometimes this works fine. I don't believe it is a cable / LNB issue since I can tune into other frequencies fine and it is a communal dish.

I tried tweaking the frequency slightly but this did not help.

When I tune to other frequencies it works fine and is stable.

e.g
/opt/bin/mediaclient -m DVBS2 -f 10847000 -M QPSK -S 23000000 -V V -E 2/3

Have you got any suggestions I can try to resolve this?

Thanks
