Tuning issues with certain frequencies

(1/3) > >>

lay-z:
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
Using device: /dev/dvb/adapter0/frontend0
Setting DVB-S/S2 tune Parameters
using HI/LO Band frequency: 10847000
Modulation: QPSK (DVB-S)
Symbolrate: 23000000
Voltage: 13 Volt (Vertical)
FEC: 2/3
Tone OFF
Frequency: 1097000
Syntax OK
Checking for lock:
. [LOCKED]

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

Thanks

Hi,

which transponder do you try to use? And which satellite does the dish point to?

Also what does /opt/bin/mediaclient -e show up?

lay-z:
/opt/bin/mediaclient -e
**** List of Media Hardware Devices ****
device 0: [Sundtek SkyTV Ultimate III (USB 2.0)]  DVB-S/S2, REMOTE-CONTROL
  [BUS]:
     ID: 1-5
  [SERIAL]:
     ID: U120411141350
  [DVB-S/S2]:

     DMX: /dev/dvb/adapter0/demux0
  [REMOTECONTROL]:
     INPUT0: /dev/mediainput0

The dish is pointing at Astra 2A, transponder 33

Sundtek:
Did you try to scan for 12344 MHz?

I get the same result when trying to tune, I tried 1000 hz intervals between what the auto detect muxes suggests, but still no luck.

Sometimes it works for a while then starts throwing errors
