Question:
Digisender interference
I’ve been using the AEI digisenders (bought from Argos) for a couple of months now to send and control sky from upstairs. However, lately I have been getting an awful lot of interference in their use, with horizontal bands of interference (and a horrendous buzzing noise to accompany it) and despite my best efforts I can’t track down what is causing it.
I know the microwave plays havoc with it (indeed, the picture is un-watchable while the microwave is in use), but something else must be causing the problem...It comes and goes from being absolutely perfect to very intruding at seemingly random periods. The interference then ‘switches off’ in a flash, like a device of some sort was causing it and has since been turned off, but for the life of me I can’t figure out what it is. Its got worse recently, but I can’t think what could have triggered this…:confused:
I’ve bought a second receiver (fifty bloody quid!) and this is doing exactly the same, so the receiver is ok, and I have changed channels on the digisender but it makes no difference.
I’ve been on the AEI web site but it does little else other than blow its own trumpet and has absolutely nothing in the way of support for the product…how nice of them.
Has anyone got any idea what could be causing it (what sort of equipment usually causes this problem?) or alternatively suggest how the hell I can pinpoint what is causing the problem?
Many thanks
One thing for concern - if the microwave is not close to the receiver and still gives interference - it suggests a leaky microwave which is cooking you too.
Its interesting you say changing digisender channels does not improve things. I think that cuts out interference like wireless LAN which sits at one channel (I have the digisender and wireless LAN and no problem). It could be a frequency hopping cordless digital phone but would have to be quite close to give such bad interference.
Thanks for the reply.
The base unit for the cordless phone is some 20ft from the transmitter/sender and about twice that amount from the receiver - would that be close enough to be causing such problems?
Is it your central heating (or worse a nearby neighbours)?
We used to have dreadful interference on Digital Terrestrial that was down to the heating :(

:eek: Is that for real? Coud central heating really interfere with these? If it could, and your not winding me up, it would kinds make sense as ours turns on and off all the time, which would explain why it comes and goes for long periods and then just "flicks off"...hmm...if it is though, I'm screwed with these in the Winter aren't I? :lol:
If it is the central heating you could test it by manually switching it and looking for the effect. The only thing that could cause it is the pump and maybe suppression could be fitted to it.
(Sounds a long shot to me).
Well, after nearly the entire afternoon seraching yesterday I *think* I have pinned it down...Turned out to be an indoor arial connected to a portable TV in the kitchen (quite a distance from the receiver & sender!). Sounds odd, I know, but I unplugged the telly yesterday and had no interference for about 2-3 hours of usage, which is about the longest I have had for a while. WOuld make sense, as its only recently the telly has been used and left on standby in the day....:rolleyes:
