Thanks. I did notice the two connectors in your screenshot. Advice taken.

Tempting... sadly, there isn't really much up in Ka for me and I only have a single cable run from the dish. It does have a free DiSEqC port but it looks like I will need at least two to make full use of it.

Would certainly be interesting what I would get here in the south. Would a bit of a triangle between me, Llew and VS.

Sadly Very little CJ ..
19.2E
Ka band A constants are currently Unrire and ITV Newsnet ...
PlayboyTV3D encrypted
Ocko which appears to have left ?
Other occasional feeds..

42East currently a 2 channel minimux aimed at Africa ..but easily receiveable

Ka band B ...only data services..


So is it worth it ?
well maybe not..
It really is more for experiment ...but who knows
All that might change as new sats are launched.

SWiM sounds interesting... The Yankies seem to be far ahead with their non-standard tech, which could, potentially, be used here... Of course, there are many other stackers available but still...

Anyhow.. been reading this - http://www.swm8.com/swm-faq.php

What are the legacy ports and how do I (or do I have to) use them?

The SWM8 has three legacy outputs (Legacy 1, Legacy 2, Legacy 3). These three ports work like the output from a conventional 3LNB dish and allow you to use receivers that are not listed as SWM-compatible. In other words, if you want to continue using a DIRECTV TiVo or some other older receiver, you can do that. However, to use both tuners on a TiVo, you must have lines run from two of the legacy ports into Sat 1 and Sat 2 of the TiVo. A few notes about the legacy ports: (1) You cannot use any splitters to split outputs from the legacy ports. (2) We recommend that you not connect SWM-compatible equipment to the legacy ports. (3) This follows from the prior note, but the legacy ports do not transmit the signals from 2 of the 5 5LNB satellites, so only the content available from a 3LNB dish is available via the legacy ports.

Does that mean that we can still use SWiM LNBs with switches (like this) that have legacy ports?

Apparently you can ..but it makes for a more complex system ...
extra psus etc.
From what I understand ..
The early SL3 type lnbs required the insertion on the BBconvertor..
later SL3s could be used with both systems ..but forward compatibility for the later set top boxes required a special switch in line..
and required an external power source of 19v ...and suitable DC blocks and splitters where neccessary.
The later single port SWiM lnbs did away with the need for the special switch ...but those lnbs only compatible with the latest boxes.
Clear as mud ..unless you have the gear in front of you for experiment.

Their latest set top boxes comunicate with the lnb and a hadshake is performed ..
Thus assigning a portion of the band in blocks to each receiver in the house ..IE stacked IF portions...
This way multiroom is possible from 1x lnb/dish on a single cable feed and each receiver capable of getting ANY channel ANY polarity ..so no conflicts.

lol
Personally I hope such tech never reaches these shores...but sadly I suspect it will one day.
It ties the user into specific hardware ...and may well drive yet another nail into the coffin of our hobby.
Great for end users ...
not so great for hobbyists.

Sounds rather similar to Unicable/SCR LNB offerings... so it's already here!

I guess you're right Alex ...
The real difference being that our native sat TV system ... Sly or Freesat ..doesn't impose their hardware on us ...
We have options ...wheras DirecTV don't like third parties involved.

Indeed, more and more providers to forcing you to use their boxes not only from the LNB perspective but also encryptions - i.e. cannot use their cards outside of their boxes. I am guessing DirecTV is making it harder than ever...

Time for a look inside ..
2 photos showing a close up of the feeds ...and a quick look inside.
A lot of similarities to the older SL3..
First thing I noted is that this unit uses more surface mount components for the big stuff ..
regulators etc..
Plus the main pcb is in 2 halves..
The actual triple lnb pcb and the 4 output duplicated distibution pcb ..
Looks more modular in it's design ..but yet to fully dismantle and look at the lnb probe design.
I doubt this will be any easier to convert to linear ..so a pseudo linear compromise is likely..but what kind of gain to expect ?
In the same way as the earlier SL3 ..this one too produces slightly better results for V when scanned as H (LHCP) in vice versa..
So ..no change there.

First the removal of the 4 port distribution board ..
To remove this it is neccessary to remove or lift the 8 links to the lnb pcb ...then desolder and straighten the 4 F connector pins ..
Then remove 8 short screws ..
This board will then lift out easily.
The removal of this board is not actually needed to gain access and remove the lnb board ..
but for the sake of completeness ..and photos for my archive..

They certainly don't waste space VS o_O

A look under the probe sections would be of interest. I suspect they will be just as tightly laid out. Afraid my eyesight's slowly circling the drain these days, so I don't relish the prospect of modding this beauty :eek:

Anyway, mine's on its way now. I'll follow your experiments with interest.

Ok ..one Ka lnb uncovered casting removed ..as is the Ku section..
Here is a photo so far ..
Clearly showing the dro osc pucks..and probes.
Unlike the older version SL3 both probes reside inside the circular feed chamber wheras the older SL3 had one probe in the chamber and the second in an anexed chamber off to the side with slot access ..
I'll have to have a good think about this as to the viability of Pseudo Linear modding ..
Hmmm..
Surprise Surprise ..the feeds are NOT circular but square ..
That has come as a shock ..
Does this mean linear is more likey ??

Looking at the probes one is already correctly positioned in the signal stream for TRUE Linear..
So can the other be turned through 90 degrees ..
I wonder..???
This would neccessitate the complete removal of the Septum cleanly ...along with the ground seperator plane on the pcb which bisects the chamber both on the top and underside of the pcb ..
Of course I can't guarantee any kind of result ..so may get another lnb on order later this month ..
Just in case..
But fwiw this lnb looks more convertable than the old style SL3
Thoughts and comments are most welcome..

You mean physically move the track's dipole round? Or am I on the wrong track? (sorry ;))
