      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      The simple satisfaction of fixing a faulty device? I fixed an old 2-way saddle-clamp wired amp - replacing the psu faulty electrolytic that gave the hum bars mentioned earlier, way back in the late 80s/early 90s... that same amp was left in the loft of my last home in 2016 when we moved. Hmmm...

      Problem solved? Perhaps. Temporarily use the PVR antenna power option at 5V it may well be sufficient??

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      Your expensive brand new meter has an 'antenna power' option :RTFM: Section 3.2 (5V, 12V and 24V options). THAT powers the masthead. Use it. Simples. 11 V from a 12V nominal 50mA amplifier draw is low (imho) suggesting poor DC conductivity in the cable? A DMM can measure ac ripple - but not...

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      Repeat at the OUTPUT of the amp in the loft, powering the amp via the meter (section 3.2 of manual says it does provide that). Or just repeat measurements downstairs with the psu-splitter removed first as a start on diagnosis of this problem. It may be something like AC ripple from the PSU...

      Raydon 4.1.3 compatibility

      The fact the 'other' foxsat programme where I asked sidecar to generate a new .nts plus the .hmt file does do the x2 etc.,. trick play just fine suggests that there is some fundamental difference(s) between the two, to my little brain. (The .ts file is unmodified).

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      NB The HDR Fox-T2 signal meter has some strange anomalies in its display of signal level --- see 'tother thread, specifically post #19 {and #27 where I had 0dB, -6, -12 and -18dB on my Sandy Heath signals}.

      Raydon 4.1.3 compatibility

      Yes. One gets the 'no can do' symbol on screen when the button is pressed. Yes. Ask it to play it goes blank screen and back to media list. The -T2-generated .hmt file is incompatible with the foxsat-generated .nts file at a guess. Deleting the .hmt file restored previous functionality...

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      Signal levels measured on all those frequencies? NB you have cascaded another amplifier (the -T2 RF pass-through) in the circuit. No chance this is related to the transmit mode unless you have two PVRs with the same fault ;) - especially as other tuner-receivers are OK. How are you feeding the...

      Raydon 4.1.3 compatibility

      Yes they do work for me. I posted after having tried some (old) Foxsat recordings on the -T2 disk. The -T2 produced a .hmi file for the one I watched and trick played. NB hmi not t; I suspect it just stores the resume play pointer. I only used to transfer files when we went in out touring...

      Raydon 4.1.3 compatibility

      One only needs to lose the .hmt files from a Foxsat recording to 'not upset' the -T2 in playing the foxast .ts stream. The .nts file can remain... Trick play, skip fwd/back works fine then (for my Foxsat record / -T2 playback combo). No thumbnails though, to choose to skip to... as I don't...

      DAB+

      Is it not possible to store the wanted stations on both banks, A and B so it doesn't matter if shift is pressed first?

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      Certainly I intend to be helpful. I was (well) paid to do the same work in the '90s. Give Justin at ATV a call, I'm fairly sure he'll tell you who supplies him with the specific antennas? Guildford is now effectively a main transmitter (one of the 81 original DTT sites) - dual line fed (a...

      Faulty Preamp PSU Caused Humax Reception Problems on Some Muxes

      Al the main 6 muxes at CP are from the same antennas and have the same, nominal, effective radiated powers and pattern (there are minor, and I mean minor variations with frequency of course). All six should be received at near-equal level. My gut is saying there's cancellations and...

      DAB+

      DAB+ uses the more recent AAC codecs cf the old DAB MP2. So should sound equally 'as good' at the proposed reduced bitrate. Classic FM is dynamic range compressed (Optimod style) so lossy codec bitrates possibly won't matter too much? On satellite they use MP2 joint stereo at 192kbit/s; On...

      DAB was an EU collaboration, the Eureka-147 project way back in the 1980/90s. DAB was fairly widely used in Europe for many years. Google the subject... https://www.worlddab.org/ may be of interest. Europe has just adopted the later audio codecs for DAB+ sooner than the UK.

      Audio Cable Mystery

      The description sounds a bit like this stuff https://www.canford.co.uk/CANFORD-FST-FOIL-SCREENED-STRANDED-CONDUCTOR-TWIN-CABLE (perhaps a picture of yours might help)? It's not stereo cable. Decent stuff would have individual screening around each of the two cores. XLR in 3 pin form is a...

      TVI FAULT

      Reading the 'other thread' the OP has very basic if not poor technical knowledge. The interference claims to be coincidental with an addition (by whom and why?) of mobile phone filtering to the antenna. Restore TV (formerly AT800) generally will only fit those outside when external...
