Okay, so there's no DC offset then, or at least it's lower than the resistance during measurement or tool low for the meter's measurement range. That's good news. Where is the DAC getting its power from? It needs 5V which is standard for a USB connection, and it doesn't consume that much...

Some of the cheaper DACs have a DC voltage (an offset) on the ground shields from the RCA outs. This should be 0 Volts, but if they haven't used isolating capacitors in the circuit design then a voltage on here can cause problems for the amplifier or powered speakers the DAC is being used with...

No, don't use the Phono input. Sure, it has a lot of gain compared to the other inputs, but it also has an EQ curve called RIAA which is designed to restore the huge bass cut required to get music on and off vinyl. There's 40dB of bass boost and 40dB of treble cut. Those are huge amounts...

^This. I stream most of what I watch, but being forced to sit through adverts with Prime and ITVX is like going back in time 30 years.

The writing is on the wall for broadcast TV via terrestrial (an aerial), and via satellite. It has been decided that internet-delivered TV is the way forward. Exact dates for the switch-off of terrestrial and satellite have not yet been set. Terrestrial is certainly not 2030 as one poster has...

Not really, no. You don't Sellotape two bits of Wi-Fi together. You don't run Wi-Fi under the carpet at a door threshold. You don't staple Wi-Fi to the skirting board, crushing it in the process. You don't twist the braid and core of Wi-Fi together and stuff it into a plug. You don't fold up...

Everyone's mileage varies. Wi-Fi quality is hugely variable. The structure of the building. The position of the router. The quality of the router. Wireless congestion. Range. Number of users. The list goes on and one. A bit of cable. It mostly works, and often superbly despite some homeowners'...

Your cables in image ending 702 are most likely professionally installed cables for a satellite dish feed. The plug in image ending 809 is a standard TV coax plug, but that doesn't mean to say it's attached to a roof/loft aerial. With a back-to-back adapter, this could have connected to a...

The age of the aerial installation is new info, but useful. Thanks. I think if the aerial had moved then more than just one mux would be affected. All the main WH muxes are running at 100kW. If the aerial had have moved, I think your reception would be affected across the board rather just on...

Pulling any cable past just one 90 degree bend can be a headache.

Except 1.) that means swapping out what could be a perfectly good TV for a Freely model since there isn't yet a Freely box 2.) not all the terrestrial channels are available via streaming yet 3.) the writing is on the wall that streaming will include mandatory adverts unless you pay a premium...

That could be as simple as the 'dodgy connection' that works some times and not others. I had a call out a few months ago like that. Reception would come and go. After checking all the stuff at ground level I got on the roof. When I came to the aerial cable connection, the whole thing was loose...

It's surprising the numbers of properties still using (or appearing to use) what looks like '80s era contract aerials. The boost in power post-DSO and the all-or-nothing nature of digital TV reception probably means if it ain't broke, don't fix it. Loads of properties still have the old...

The Winter Hill muxes go down Ch. 21. If you have a group C/D aerial - something tuned for optimal reception from Ch.48 to Ch.68 - its reception will go lower, but by about Ch. 26 you're flogging a dead horse. For a home in a high field strength area, a bit of poorly shielded coax might be...

An attenuator just reduces the signal strength. It doesn't increase it. What it does though, being a passive device rather than amplified, is that it leaves the signal quality unchanged. It reduces the power without reducing the quality. It's a good diagnostic tool. Next time you lose signal...

Try a variable attenuator at the socket of your main TV. Reduce the TV's signal strength to about 70%. See how you go.

There's something in what @foxhole says about the age of your wireless router. Quite a while ago, BT were making a big play about their Wi-Fi coverage being the fastest. This was with their new BT Hub router at the time, and it's still relevant today. It was fast. They were running 5 GHz...

The same signals that Sky uses as part of its channel package are also used for Freesat. When a Sky subscription is cancelled, Sky can (and does) switch off access to the paid-for subscription channels, but the other ones stay active. For this reason, I think the issue is more likely to be some...

Hello, and thanks for the info so far. Answers to questions asked so far: Batteries - Duracell and also a new set of Energiser (my preferred choice as they don't leak, unlike Duracells Override on HC60NG receiver - Yep. Green light. Heating set to +1 hr. Pump and boiler fire. Rads get hot...

Hello gurus of the CH world. We have a Honeywell Y6630D analogue room stat and receiver/relay. I'm not up on the terminology of boilers, but it feeds a hot water cylinder if that gives you any clues. HW works but CH doesn't. I suspect the room stat has died. I have changed batteries in the...
