Philip,

you will already have fun to buy a TBS-5925. It's not produced anymore and the
follow up TBS-5927 has no loop out. Whether the SR1 is still available I don't know.

Ernst
Thanks for the explanation to a non techie like me. 
So if i use the loop method i can keep the existing bas and hvs-1 on my SR1 and use the TBS-5925 for the hvs-2
many many thanks to all on this topic

Has anyone used that arrangement successfully
Philip,

the problem ist that if you have only one cable then only one device can feed the LNB and command, whether High or Low band and H or V polarisation.
We are in the lucky case that EUMETCast transponders T1 and T2 are in the same band and polarisation. This and only this allows for the single cable
solution with Bas, HVS-1 (T1) and HVS-2 (T2). If you use a TBS-5925 in front loop out to an SR1 then the USB box will be in command while the SR1
"sees" a DC block ahead. It's the same with a splitter. One side will/must have a DC block while the other side lets you feed the LNB. So also with a
splitter and two SR1 receivers, one of them will be in command to feed and steer the LNB while the other "sees" a DC block ahead. Whether or not this
DC block does impair the SR1 behind I do not know for sure (but I do not think so). Christian Peters has used a system where he fed the signal through
two TBS-5925 USB boxes (both with loop out), one TBS-6925 PCIe card (that also has a loop out) to a final TBS-6983 (... don't try to beat this!).

Would -27dbm by high enough. Its probably not so i really need the TBS5925 and loop thru to the SR1. Has anyone used that arrangement successfully.

Philip,

There is no way you can "link" from the TBS 6903, as it lacks the passthrough capability of the TBS5925 (USB box)..

It's the signal level which matters in terms of how you handle it t the receiver end. If the SR1 is showing a level of -35 dBm or higher, the I would suggest a single cable from the antenna, a two-way splitter with ideally one DC-pass port connected to the TBS 6903, and a DC-isolated port connected to the SR1.

Actually, I've not tested the SR1 with a DC-isolated antenna, so I hope that would be OK. Likely alternative combinations are possible. Can the TBS5925 (USB box) handle both HVS-1 and BAS?

Cheers,
David

Thanks ,thats an excellent explanation. I think the way forward for me is to ditch the Ayecka and use the TBS-6903 PCIecard for bas, hvs-1 and hvs-2, although i have got used to the Ayecka and its configuration.
The LOOP output sounds interesting though. I presume the link aerial cable exits the TBS-5925 and in to the Ayecka RF2 as the other empty slot is a mini usb CONTROL .

If you have a marginal signal (SNR less that 12 dB), I would suggest using the TBS6903 for HVS-1 and HVS-2, and keep the Ayecka SR1 for BAS only (set the PIDs accordingly). This maximises the chances the BAS not being affected by drop-outs on the HVS1. Info on my Web site or in the EUMETSAT guide.

You can use a single-cable to the TBS6903 as documented by CrazyCat and referenced on my Web site. So providing the signal level is reasonable, a splitter before the SR1 and 6903 may work well. I have seen issues, though, when using the single-cable 6903 solution that it needs a DC path to the antenna/LNB.

Hi Ernst

Yes thats the problem

They say the ship using DHL and I am quite happy to pay that but I cant see anywhere on the site that allows me to select anything other than standard shipping

If its at the checkout stage then that is a problem because I can never check out because of the shipping issue

Graham,

in the FAQ they say that they deliver worldwide. Maybe you have to pay a little more for a faster delivery service?
Christian Peters can eventually comment. My PCIe samples normally ship directly from the TBS head quarter :-).

Graham,

I don't know. Find out whether the TBS shop does not ship to UK for technical or political reasons.
A technical reason could be that they come out with the "final" design shortly. The shop you link to
shows an image of the very first series V10 from 2017. You should make sure that you really get a
V11 or later *THAT HAS THE 22uF MODIFICATION* I described below. Christian Peters bought a
TBS-6909X last year from the TBS shop and he got a V20 still hand modified with the 22uF cap.

Hello Rob,

Happy New Year to you and all our Dutch members.

Thanks for the animation.
It's interesting to see the (increasing?) speed of movement over the last months of the iceberg and how close it came to South Georgia.

Best wishes,
John.

Hi
Although i am a little confused as i can see Hugo,s post `Yes you can use one cable and a splitter ... the two transponder frequencies have the same polarization... so no problem`.
