Soarview / Technomate HD Modulator

Hi,

Has anyone any experience with using a Technomate TM-RF HD IR in conjunction with Soarview?

I bought one to remove the bad analogue Skybox RF2 out distribution system I had and so now I have an extra channel on LCN 800 for the Skybox via DVB-
T - The problem is that the quality is very inconsistent, it works well at times but the signal can go from bad to gone totally - a situation in which I can lose also the Soarview channels and a rescan must happen.

I tried the DB levels and added an attenuator on the RF-in also but little if anything seems to change.

The Setup is like this:

Antenna > attenuator 6dbm > TM-RF HD rf in > Rf Out to Distribution Amp > TVs
Skybox > HDMI upscaler > TN-RF HD HDMI in > HDMI out to main TV

I don't have the TM device but do use an equivalent Edision device.

I have full strength output from a HDHomerun tuner added to the RF input of the Edision and a Sky+ HD box HDMI input.

I have had no problem with the signal out ...... shows 100% signal and sometimes more.

I do not understand why you would have to rescan for Saorview channels, unless the TM output frequency is drifting causing the TV to be off tune.

Maybe check to see if there is any setting in the TM which might help.
Do you reboot the TM regularly? If not maybe a reboot would help settle it if that is the cause.

I cannot presently think of anything other than the TM drifting.

A point to note with these units the modulator RF IN isn't really an aerial RF IN but a cascadeable connection between modulators.

Which explains why my setup worked perfectly.
I had previously used a splitter to combine aerial and convertor outputs, but had totally forgotten about that.

That's it.

Just one other point, if it happens that the modulator's feed through the amp overloads the TV's tuner stick the attenuator in between the splitter/combiner and the modulator.

Does that modulator not have an adjustment for its output which would do this?

I don't properly recall but believe that the Edision does and they seem to be the same device under different names.

I kept my -6db on the aerial side and on the Modulator I have a -10db to +16db range - currently at 0db

What's the reason for the attenuator on the aerial feed? Most people posting here would have low signal issues rather than too much from the aerial.

I could probably try without as I added this when still using analogue channels, without attenuation I was getting ghosting. I will see about getting a cheap DB meter if that exist to check levels - what should it be? Im on Clermont Carn (Louth)

50 dBμV - 75 dBμV at the wallplates is recommended. Less should be OK if you're plugging the aerial direct into an amp.

In my brother's setup the aerial is combined with the Technomate modulator feed in a combiner external of the modulator, why it was done this way I don't know but it works.

This is a similar setup I found via google

Found a pic of my set up for comparison.

Maybe your brother's set up was done from the pic?

Maybe. His install was done by a professional installer in the Limerick area.

Im intrigued by this network and Sky Box Control thing, can you elaborate on this one?

Here is a quick drawing of my setup at present

This post has the same pic with some explanation,

This scheme is not for everyone, but it is the most versatile I have found, and is easily tweaked, adjusted and changed. Even the hardware is not specific (except for Sky box) as all parts can be replaced by preferred equivalents.
The same applies to the software used.

I was aiming to create the system at as small a cost as possible without compromising on variety of function.
Certainly, replacing some hardware, such as those generating the display for TVs/monitors with some higher powered devices would most likely benefit those requiring UHD, HDR, 3D etc images.
For my needs .... HD displays only and no requirement for fancy graphics and information for the library and such ..... the lower spec and much cheaper hardware is well capable.

Interesting, didnt know this was a thing! One thing that isnt clear on your setup is where and how you connect the TVs? Ethernet or Coax?

As for my system, I already purchased an ~Enigma2 box running Wooshbuild with SKy+ Skin (ZGemma H7S) and it will replace the Skybox soon - I can stream on phones and tablets, record, etc...

The data is distributed over the LAN ... both wired and wireless, but wireless is not really suited IMO.

I use a low powered device like that used for the wee server (Tanix Tx3 mini or such) running CoreElec or LibreElec with Kodi.
This then feeds the monitors/TVs with HDMI signal.
I have no 'smart' TVs, but if one has Kodi in it apps then that could be used directly with ethernet cable along with WWW access.

Kodi can access all tuners; set recordings; replay recorded content and any other media stored.

All recordings are stored on a central file server/NAS and all devices on the LAN can access them.

It is suitable for some but not all ..... is great for multi point receiving and there is only one set of tuners and no coax distribution to TV use points.

So, from a cost perspective, one receiver box rather than multiples, in central location, with the small TV boxes costing about €40 each at TV points.

If in future UHD becomes generally available, and a suitable TV/Monitor is purchased for one location that is all that is needed to be changed, maybe along with its Kodi device if that is not capable of UHD (quite a few are, even down at that price).

Ever want to add a TV somewhere unforeseen?
Hopefully location has LAN wiring, but if not then Home Plugs or similar or even wireless can be used.

Over time the use case in most of the rooms in my house have changed, and whereas previously I would be looking at getting coax in and buying a new receiver and HDD etc to be able to watch TV or film, this scheme covers all that over the LAN.

Yes I can see how it has some great advantages but geared more towards tech savvy - A solution I could see myself using if SHE wasn't around :rolleyes:

Im hoping soon we will see multi channel HD modulators - could do with 2 at least but don't fancy cascading another one, its greedy in Power judging by the heat dissipated!

Thankfully SWMBO is ok with it here as I set up the channel list in the order she wanted and I do not allow that to change.
I set it up in parallel with an existing STB before switching to it permanently.

The client box is switched on with the TV and the one remote is sufficient because all media is accessible from the client box.

HDMI>DVB-T modulators are a waste IMO, but needed for the likes of Sky. I know of no other use for them TBH.
There is an Edision version with twin HDMI inputs ..... believe I came across it some time ago ..... but of course they are costly.

Me being the cheapskate that I am want everything I use to be cost efficient.
