Problems tuning multisat unicable setup

[armanic78]

Hi all,

First post, but long time lurker, great info here, but can't just find the answer I need for my problem.

Firstly, my setup:

• a SelfSat H22dCSS+ Unicable, pointed at 28.2e Astra 2 (original setup)
• a 90cm dish, with 2 x GT-Sat GT-S1DCSS24 SCR/dCSS Unicable LNBs, centered on 13.0e Hotbird and 19.2e Astra 1 offset with a multilnb holder (this is new)
• a Gigablue UE 4K with OpenATV 6.4, with 2xDVB-S2X FBC and 2x DVB-T tuners in optional slot
• a simple Technomate 4x1 Diseqc TM-4S
• a server with a TBS6909 DVB/S Octo feeding into TVheadend + a card for DVB-T.. can't recall the model

The Selfsat dish has been up for a while along receiving Freesat, and I have separate a terrestrial feed (am in Ireland, DVB-T is for local Saorview). These have been feeding my previous box (Formuler F1) & TVheadend ok for a while with no issues. I upgraded recently to the Gigablue UE 4k and then also put up the new dish which I had previously + 2 new unicable LNBs, and introduced the diseqc into mix:

- port 1 = 28.2 Astra 2
- port 2 = 19.2 Astra 1
- port 3 = 13.0 Hotbird
- port 4 = unused

I've completed what I think is the tuner setup on the Gigablue, and am getting 28.2 coming in ok (as well as the terrrestrial) but I cannot get any signal on 19.2 or 13.0, or not at least consistently. There are 2 cables feeding into the DVBSX2 ports on the gigablue. I should also say that I've tested the output from the 2 new unicable LNBs by putting a meter on their legacy ports, and am getting 80%+ signal on the Hotbird, and high 60s%+ on the Astra 1 and both are locked and displaying channels.

I had originally setup all 8 tuners, to be multisat:
- LNB 1:
- - Astra 2
- - appropriate Unicable SCR & freq
- - Diseqc 1.0
- - Port 1
- LNB 2:
- - Astra 1
- - appropriate Unicable SCR & freq
- - Diseqc 1.0
- - Port 2
- LNB 3:
- - Hotbird
- - appropriate Unicable SCR & freq
- - Disqec 1.0
- - Port 3
.. times 8 for each of the tuners, changing the SCR setting each time to give them a unique address on the 3 LNBs, but I decided to pare this back til I got things working.
At some stage, I had stumbled across configuration setting which meant that I was getting some channels coming in on Astra 1 19.2 once I did a scan, but I dunno what I had set :-S

Note that TVHeadend has a similar setup, but is able to tune both Astra 2 & Hotbird, i.e. not Astra 1 19.2, so am not thinking that it's a cabling issue, especially when 28.2 works ok
Here's a sample of the settings for one of the tuners, pointing at 19.2 :

My hunch is its something to do with getting getting the Diseqc working correctly, but can't work out what's the best settings for me.

Thanks in advance!
