Treated myself to a TBS 5927 (to join my SR1, TBS 5925 and TBS 6903 !).
Can anyone confirm that they no longer come with an internal fan.

I know when they first appeared that they had a very noisy fan and some people disconnected it and found it still ran cool.

I hear nothing from the unit and looking through the ventilation area on the top seems to show an aluminimum heatsink.

Runs slightly warm. Just want to make sure I don't have a faulty unit.
Too expensive now to open under warranty !
Nothing mentioned about fans when I check on-line, but that applies to the first models as well.

Regards,
Douglas.

I've been using my TBS 5927 for quite some time with the fan removed without any issues. Indeed it's slightly warm but nothing that worries me.

Douglas,

I cannot comment on the TBS-5927 except for that a couple
of users said it does not work under Windows as well as
the  deprecated TBS-5925. Maybe this is now improved by
the new and more standard signal we get from Telespazio.

I just wonder whether you bought the TBS-5927 as a spare.
It should be possible that with your "so far" receivers you
can use all current and near future EUMETCast services:

BAS only with the SR1 (or TBS-5925) and MODCOD filters set.
HVS-2 with TBS-5925 (or SR1).
HVS-1 and future HVS-3 with TBS-6903 in single cable setup.

Ernst

Thanks for the report Andreas.
What I am trying to find out is if the TBS 5927 is no longer provided with the fan.
My new unit, just purchased, either does not have one or is faulty.

Douglas.

Thanks for the reply Ernst.
I am now running my Eumetcast system reception very successfully from a mini computer, allowing my main computer to concentrate on all other tasks
Because of this my TBS6903 card is obselete.

I use my SR1 for basic, TBS 5925 for HVS-1 and hopefully TBS 5927 for HVS-2 or some other mix. Equally it could act as a spare.

As an aside, I also updated my LNB from a twin Inverto HGLN 40mm ultra LNB to a quad in readiness for an extra feed.
However despite the online image showing the long body Inverto ultra similar to my twin, what arrived was the new quad ultra with pll.
This has now replaced the old model which is no longer available.

Weather here is completely unsuitable for testing at the moment, but I did get a good 4 hours on the day it arrived and I am very dissapointed with the results. My dish is at ground level allowing easy and accurate adjustment . The twin inverto when removed was giving a SNR of 12.5. I have been unable to even reach 12.00 with the new one despite constant adjustment of focus and skew.

More work needs to be done when weather settles (little chance in next 10 days) but initial tests are not good.

Will report back in due course.

Regards,
Douglas.

Douglas,

I have given Robert Moore these three links below a few days ago. I urged him to buy fast ...

... and he wrote: "Meanwhile I have managed to get hold of an Inverto Black Ultra HGLN Quad LNB."

It seems the original is still available. I have not seen an image of what Robert actually got though.

Ernst

I was sorry to read that Douglas but very grateful for the test and warning!

Sorry,

this was foretelling. Contrary to what he wrote Robert has got the new short necked PLL model as well :-(.

This is the problem Ernst. Sellers web sites are way behind new stock.
I suspect there may not be any available.

I am not giving up yet. Those in the know tell me that pll LNB's are normally the best and often expensive.

Trouble is that I need time with good weather. My situation at the moment is made worse by having my snow/rain shield off whilst I am messing about with the LNB. As I said the forecast suggests testing will not be possible for a while. No days without rain.

Still despite a signal in the 10s and low 11s, I have not lost any packets today. HVS-2, of course, is impossible at the moment as it is always 1.2dB down from basic and HVS-1.

Anyway a small distraction tomorrow with FES sat change to Meteosat 10.
What a fun hobby ?!

Douglas.
