There's an awfully long thread on the freesat 4k box on AVForums where this might have been discussed?
One other place to look is DigitalSpy where an ex-colleague who was the de facto expert on PDC and AR, posts.
Each box/maker will design how they work within the specs for DVB, with...
A Radio Ham (fully Licensed one hopes) that thinks a passive 4G/5G low-pass filter inserted in a UHF TV antenna system might be the issue (unless poorly installed) and has no idea on how to check that (e.g. by removal, temporarily).
My mind boggles.
Is use of such a large gain collinear...
$ky Q has no legacy mode afaik. Wideband or dSCR only. $ky simply swap the universal/legacy LNB for a wideband one reusing the old cables.
freesat 4k boxes have all 3 LNB type compatibility.
dSCR comes as standalone LNB or in Multiswitch forms using inputs from Quattro or Quad (or even 1 or 2...
[Off Topic] AFAIK only the $ky Q and freesat 4k boxes use the wideband LNB. Other multituner devices tend to use dSCR single-cable options (that Q and freesat 4k can also use) to 'instruct' the head-end to send the wanted Transponder down that single cable. Even the Foxsat-HDR has an early SCR...
Sounds to be a different problem to me as it's occasional rather than 'regular' timing.
No harm in installing the CF and using the disk diagnostics though.
READ the faq manuals and stuff first. There's quite a bit of (not difficult) learning about what the whole thing does and what you need...
Rowridge Vp was Planned by UK Spectrum planners to protect from co-channel Continental transmitters using Hp. They expected new aerial install/replacement in the areas served to use Vp rather than Hp (and eventually not need Hp transmit). Then Arqiva did the COM7/8 thing. ;)
How was the aerial...
None of the professional spectrum planning prediction tools can account for building clutter nor trees. That stuff is simply not mapped fully, nor necessarily accurate and up to date. So the public domain ones simply cannot, either. It's why installers have test aerials and calibrated...
Trees then. Reception killers and variable frequency attenuators/reflectors giving standing waves and other issues. Especially when wet and windy. Probably not possible to get 'under' the foliage for a clearer view with an aerial?.
Grid aerials are fairly good at receiving through foliage...
13 miles from Rowridge on that bearing is Fawley/Hythe area.
There's nothing topographic that obstructs the view to the top of the mast - the antennas are over 280 above sea level. Only local trees / buildings / structures (Fawley refinery?) might do that (and or cause unwanted multipath...
PLEASE
Do make a full set of Signal/Quality measurement on both Aura and your -T2 before altering the aerial.
and Repeat them when canted over to Vp.
I'd really like to know the Field numbers from Wolfane for Rowridge Vp and Hp (though it should be -6dB on Vp as Wolfbane gives the number for...
Q drop coinciding with picture breakup is - potentially - indicative of signal overload. Classic description of the issue.
Different tuners in different devices have different capability in presence of high signal levels... the -T2 may be more prone cf the TV's tuner?
Check out if you have...
The -T2 readings for the two muxes measured to date don't suggest overload to me. Especially as the Aura lost signal with the smallest attenuation added.
There's a chance of interference under enhanced propagation if such a large array if pointing Continent-wards. The Vp signals are more...
https://www.aerialsandtv.com/product/xb16a-aerial is a mahoosive antenna! Not the greatest gain at 21 cf the rest of Band A, but nevertheless higher than any decent quality alternatives. Likely in a fringe location there will be diffracted signals over hills/ridges rather than line of sight...
Just for fun and 'cos my box of fixed metal barrelled attenuators was to hand I added 6dB, 12 dB and 18 dB, in turn, between the aerial feed and my -T2. In addition to the 4 dB splitter loss to feed it and my OLED TV.
All measurements via the Humax UI signal condition. {My previous post...
Interesting. My -T2 on Sandy Heath measures 71% on ch 21 (HD); 75% on 24 and 48; then 74% on 27, 33 & 36. All 6 are at an identical erp. The aerial in loft is a bacofoil wideband 'high gain' job {came with the house} and likely droops in gain at 21 cf the rest.
Access to the diagnostic...
Only the temporary COM7/8 muxes were Hp only. The main 6 were always Vp at the same 200 kW erp at DSO.
No harm in reducing the input level to the Aura as a test, of course. A passive 2-way splitter is -4 dB if you have one.

ROWridge has two polarisations transmitted simultaneously for a reason to do with interference from the Continent.
Effective Radiated Powers are:
Horizontal: 200 kW for the 3 PSB muxes and 50 kW for the COMs (-6 dB).
Vertical: 200 kW for all 6. {This polarisation gives better interference...
The Rights Owners generally insist the Sports is on the 'flagship channel'. e.g. It's why certain Wombledin matches are on BBC ONE and not BBC TWO.
I guess that ITV reckon few would find GMB on one of their 'other channels' (or it's simply cheaper to not make the programme and make staff and...
Absolutely correct. NUJ action.
Protesting about Local Radio / English regional broadcast news cuts (moving to online) etc.,. I noted quite a few East presenter/journalists on items from the London-delivered pan-South/East England last night. So not all are in the Union it seems.
