    You need to be in a large urban area to easily find a pub that shows footy on tele - When you're on a wildcamping.co.uk site, there's unlikely to be a nearby pub, even less likely one showing footy! She indoors can watch the footy while I watch the wildlife...

    Can work, but you need a 3G mobile phone signal. I have a decent limit, but coverage is often poor on the coast and in mountainous areas ;-)

    Interesting; I could take the old sky box (I'd be happier with that, as it's less delicate, not having a hard disc), but how do I reassign the card to the old box (and back again when I get home)? Should work for Sky Sports and BT Sports channels.
    However, I guess I would not get the HD-only footy channel for 'she who must be obeyed' - the reason for getting the Sky+box.

But one of the channels we pay for (a channel for a football club, my wife's interest) was stopping SD output, only HD, and we had the choice of either getting a free upgrade to HD or stop watching the channel. For domestic peace, I did the swap. I then had the problem of how to get the Sky+HD box to work in the motorhome. At least, it's not the 'New' sky box (Quantum or similar), so it has a co-ax output, or I'd have to change the TV!
    I only need a Sky box for premium channels, as the Icecrypt gets the freeview channels off Astra2 and some off Hispersat (useful if hills are to the SE or in Europe). It may be that I could use the old Sky box, by reassigning that to be the prime receiver (how do you do that?), but I would still not get the footy channel for 'she who must be obeyed'
    Sky multi room boxes can be had on fleabay for £15.00. All I do is put my Sky card from home into it and when I go onto a sport channel it tells me to go onto Sky.com/quickfix to pair the card to the box. It takes 2 minutes. I usually do it when I arrive at my destination or if I know I won’t have a signal for my mifi at the location do it on my drive before I leave home.
    When I arrive home I just have to put the card back into the house Sky box and when I go to a sport channel it tells me to press select to pair the card to the box, again a a 2 minute job.

    Forgot to mention I pay for the Sky sports channels most of which are HD and donít pay extra for HD. I believe all sports packages are in HD for no extra cost.

    From Sky.com - Sky Sports: Sky Sports channels available in 1, 2 or 3 channels or get all channels with the Complete Sports Pack. From £18 - £30 extra per month. ... Sky Sports in HD: Included as standard with any Sky Sports pack. Sky Sports or Cinema on a contract: Requires new minimum term on your Sky TV subscription.

    It's only the specialist channels that are only HD, not SD, e.g. LFCTV, Man U TV, Chelsea TV. Your method would save disconnecting the Sky+HD box, but the box needs to be HD to keep her indoors happy. ;-)

    Just checked the Sky website and found the relevant page:
    I'd just have to plan in advance and transfer the card before setting off (and it says leave box on for 4 hours as it indicates the reassignment may not be instantaneous)

    I see on managing the system on the website it says:

    "Please make sure the box youíre trying to pair with your viewing card is either a Sky+ Box or Sky+HD Box.

    If you have a different box, you'll have to contact us"

    So, it implies I'd have to contact them if I wanted to use my old box or a multiroom box. How do you manage to do it?

    Itís virtually instantaneous when I pair the card with both boxes.
    Never had a problem with the multi room box, just give it a try and I reckon it will work.

    Don't believe the meter

    However, when we want to watch encrypted programmes, we need to use our ĎSky plus HDí box, which requires a 240V input.
    Our old Sky box worked well powered by one of two inverters. One is high power (300W), the other small (50W). However, the new box seems to be more sensitive to the input voltage (I assume) as it works erratically, and when I checked with a DVM both of the inverters had an output voltage (little or no current flowing) well over 240V - over 300V!!! I guess it is tripping out when the voltage gets too high. The work-round has been to use a generator which provides the required 240V +/- much less than the inverters. But this is far from ideal. Don't like disturbing the countryside when we have found a good 'wild' place!

    I have seen various voltage protective devices but the problem can be that they cut the connection if the voltage exceeds a certain value. What I require is a device that will limit the voltage, constraining the output rather than disconnecting. If it cuts, the box goes off and takes time to reboot. As I see it, it needs a well-regulated power supply, like the ones used by laptop computers that provide a stable output regardless of input voltage from 100-250V. Would a surge/spike protector sold by computer shops do the job?

    Or can I break into the Sky+HD box, by-pass the power supply board and connect 12V directly to the main electronics?
    If your inverters have "Modified" or simulated sine wave outputs they can be very difficult for a modest DVM to read with any accuracy. The simulated sine wave is generated from a 300+ Volts DC source inside the inverter which is the "chopped" into small slices to form something more like an undulating staircase than a sine output. Unless you have a "True RMS" meter, you'll get very misleading results with your DVM. Comparing the reading on your domestic "true" sine wave supply will only demonstrate the difference.

    You would probably need a "True sine wave" output to run anything that's sensitive to the unusual waveform from the "Modified sine" output.

    It looks difficult to get an inverter, especially a pure sine wave inverter, of less than 300W! I don't want to get an over-powerful inverter as it's likely to draw a higher no-load current than a smaller one - conservation of battery! Brands and models of quality proven inverters would be appreciated!
