Melbourne Australia SBS Multiplex freq change

Jan H

The digital TV frequency for the SBS Melbourne multiplex here has changed form 536,625kHz to 184,500kHz.

Both frequencies are working until February 7 2014 BUT I cannot get either to work..... It used to work with 536,625kHz without issue on the Raspberry.

I completed a fresh install and since then neither frequency will work.

All 4 other multiplexes work as they should without issue.

Any ideas? I am lost.

These settings should work:-

frequency: 184500khz
bandwidth: 7mhz
constellation: 64-QAM
transmission mode: 8k
guard interval: 1/8
hierarchy: none
FEC Hi: 2/3
FEC Lo: none

Version?

Debug log?

Raspberry Pi running HTS Tvheadend 3.4-dirty.

What logging would you like? And how would you like me to go about it?

I have removed the /home/pi/.hts folder and started from scratch - no change.

Whenever I tune by region it loads all 5 Multiplexes correctly but SBS is on the wrong frequency 536,625kHz but it should still work till 7 February 2014. I understand that it loads this frequency because that is what the region is predetermined by TVHeadend. Under Network it should say SBS Melbourne but it is blank. All other muxes have the network name.

I load a manual muxe form the correct (new) 184,500kHz frequency and it stays blank and I get no services.

Many thanks in advance.

I need to do some more investigating and testing but I think this may be related to reception issues through my DVB-T adapter.

PCTV Nanostick T73e.

The TV reception check says 10/10 but signal strength through the T73e on TVHeadend is reporting anywhere from 27%-42%.

Not sure what to do?

Hi guys, just came across this post after I lost SBS (ie the only channels worth having a month or so ago and just had some time to mess around)

Ive tried adding a mux manually to Tvheadend and removing the old one, and rescanning without success so wondering if this is the same issue? Strangely this dude got it working:

Heres my logs if it helps anyone, in the meantime i'll keep playing! Hopefully theres nothing hardcoded

Details:
Openelec 3.2.4 Fusion x64 with a Playstation dual-tuner

HTS Tvheadend 3.4.27~gfbda802

From what I can see, it seems on channels Nine, Ten, Seven it does something, while the no-name SBS freq of 184500 it just bombs.

this is interesting, maybe theres poor signal on this new frequency...

Yes, getting the "Faint signal" info as well.

I've got another dvb adapter working as someone has provided a working kernel for it on my Pi. It's a Terratec Cynergy T Stick+.

I've created a new Multiplex for SBS based on the 184,500 kHz:-

"quality": 100,
"enabled": 1,
"status": "OK",
"transportstreamid": 784,
"originalnetworkid": 12802,
"network": "SBS Melbourne",
"frequency": 184500000,
"initialscan": 0,
"bandwidth": "7MHz",
"constellation": "QAM64",
"transmission_mode": "8k",
"guard_interval": "1/8",
"hierarchy": "AUTO",
"fec_hi": "2/3",

"fec_lo": "1/2"

I wasn't getting the Network name but for some reason it now comes up. Once I set up this new Mutiplex I then went back to the General tab, removed SBS 536,625 kHz and for the new adapter disabled "Autodetect muxes".

It now shows SBS Melbourne under the Nework name for 184,500 kHz. Progress made.....

Now to do some further testing. Will report back.

For anyone else out there having issues, I had another play and got this working after lots of trial and error. Thought I needed a booster, antenna check etc etc but works nicely now without all that. It'd be interesting to know what the Auto values for fec_hi, fec_lo etc do since thats all I changed...

Jan H

I think, with my limited knowledge, that FEC is a form of error correction. I think setting AUTO is fine.....

My services are all working fine now, in particular the new SBS Melbourne that I had set up.
