Hi All,
After setting up correct frequencies for the Nelson Region on my HTPC I've notice the transmitted signal keeps changing from HD to SD and the sound from Dolby to PCM, also on my Panasonic GT50's own tuner it does not allow on screen EPG listings.

My questions are, Are any other regions affected in the same way and who accountable.

Let's hope it's all temporary and will be sorted soon.

I'll just quickly add, I have checked the signal strength and it's 100%

I've also noticed the same problems with a stand alone box in another part of Nelson.

I expect it's transmitter issues.

Hi,

are you trying to look at Mainland TV or services on the Freeview muxes? Mainland do their own thing and are not hooked into Freeview but I believe they have logical channel numbers none the less so you should be able just to use your up and down buttons on the remote to change channels. Mainland's website did at one point have the details of its broadcasts as it uses a mixture of MPEG 2 & MPEG 4

regards

There is a known issue with the transmitter in Nelson. We experience the same issues here in the Wairarapa from time to time.
I hope JDA sort their stuff as it is quite annoying,

The backhaul is being upgraded so they decided to use the sat service as the terrestrial feed. Really unacceptably poor in my mind.




Spark FibreMAX using Mikrotik CCR1009-8G-1S-1S+. UAP, UAP AC Pro, UAP AC Pro Mesh, Apple TV 4, Apple TV 4K, iPad Air 1, iPhone 6s, VodaTV Gen 2. If it doesn't move then it's data cabled.

The link to the transmitter has a problem. High temperatures are causing the linking signals to fail in the evening in summer. The satellite feed is being used as a backup during hot conditions until the linking problems can be addressed. The link path is complex. (A fibre feed followed by three microwave links I think. One microwave path is causing the problem).

PS "backhaul" is a term used to describe the return of a signal to the studio from the transmission area. The link in with the problem is a STL, (studio to transmitter link).




don't mess with me.... i'm the hd insider....

I notice these problems every few weeks or so here in the Wairarapa. We were having a thunderstorm and the backup sat feed was chocking too. It was very painful to watch and our TiVo was not enjoying the experience. I kinda feel sad for the tivo. I think the transmitter should switch to colourbars or something if the sat feed stopped working.

As I am in the Wairarapa I would guess that there is no fibre out to our Popoiti transmitter. The otahoua transmitter maybe as it is owned by kordia.

When the transmitter first started broadcasting FreeviewHD there was a period (About 4 - 5 hours) that the HD feed was shown. Then it switched to the sat feed and stayed that way for several weeks before the broadcast was 'official'.

pdt1968: I have checked the signal strength and it's 100%


Do keep in mind the the percentage signal strength reported by tuners in TVs, set-top boxes etc is a bit meaningless. Your 100% will be different to someone else's 100%.

Even for checking how good your signal is from day to day, the reported signal strength isn't that useful. For that purpose it would be better to look at the reported signal quality rather than strength.

My readings were taken with my laptop using scanchannelsBDA linked with a meter of cable direct to the aerial, I don't have access to professional meters so this is the best I can do. The loss through the full length of cable was minimal.

I only mentioned the signal quality because I have all new quality cable and new aerial so didn't expect this to be the problem. Also fitted new to the inlaws and they have similar issues, they were all fine when origially fitted.

I also wrote a post on Freeviews forum and a few people have got back with the same issues in the Nelson Region.

I appricate all the feedback, Thanks again, I hope they finally get it sorted before their official switch over date.
