Hi all and if so HNY!
Out here in the start of Summer it is mid 30's °C on the roof already and I have a new OS MIO+ 4K and Unicable to get this elusive OPTUS D1 (https://www.lyngsat.com/Optus-D1.html) satellite with all the ABC/ SBS (Australian Public FTA broadcasters) lined up after an interval of 5 years without, interim we have had to use the beastly VAST, pay for access (sort of) not all services available and a 3 second channel change delay on a good day.
Australia is a big place, there are feeds for every time zone on D1 and as we are a Sheep Station, well inland, it is handy to come in late and record/ watch something from an interstate feed which can be 1hr ahead, ½hr, 1hr, 1½hrs or 2hrs behind our Eastern time Zone, :) yes five time zones when horrid DST is enabled and three time zones for the disabled DST six months.
The satellite is over head 11° East and has a low signal because the broadcasting sites where it is designed for have typically 4M+ rx dishes, BUT all TP's here are within 2% RSQ.
So, I have a 1.5M PF (prime focus) from Australia's first system in the 1970's called HACBSS (Homestead and Community Broadcasting Satellite Service) which was connected to a B-MAC decoder from Scientific Atlanta ! (I still have the decoder and it was the first sold in this area).
Anyway essay over, time moves on and multistream comes to D1 in 2017, so our DUO 2 can't sit with that, but the Edision now can. :cool: (More later/ in the MIO+ 4k thread, wrt).
From the PF dish I get fairly good stable results of about 85% signal quality.
On another I have a 1M with a new GT-SAT GT S1dCSS24 Unicable LNB from WOS, fed with low loss quad shield foam ½" 75Ω.
When I connect to the (GT-SAT GT S1dCSS24) legacy port on D1 the Edision gives stable and better quality than the PF as its NF is 0.3dB whilst the GT-SAT LNB is 0.1dB, which is rare here for LNB's and cannot be bought/ found in Australia at that low figure.
However when I use the Unicable port and set the Edision to what I reckon are the correct choices (see following images), the signal pulses in and out, from 88% to 0% all the time, with a sequence of six seconds.
So at 0s = 88%, 3s = 40%, 6s = 0% RSQ ! Over and over on a loop (have I said something there?).:confused:
There is a Telstra approved/ branded 700mHZ cell extender antenna along from the Unicable dish, but turning it off doesn't improve the behaviour.
I am sure there will be instruction (to novice) from the big KB which is VIX/ WOS !!

Change to Unicable LNB
