Losing Some Channels On Sky+

[nezo123]

Hi all, hope someone can help me out, im new to this forum and this is my first post. The problem i am having is i am unable to view some music channels, they are ok from CH. 340 (MTV) upto 354 (Q), when CH. 355 (chart show tv) is viewed my picture breaks up i lose the audio, or i get there is no sattelite signal message, this happens on the same channels every time (channels, 355, 356, 357, 362, 364 and 366),
I phone SKY and they told me to try another channel, (CH. 323 True Movies), which i did and this was also breaking up and unwatchable.
i was advised to reboot the SKY box which i did by unplugging the mains and plugging back in after 1 min, this did not fix the problem, so they sent an engineer out who when arrived a few days later the problem was not there, (all my channels were working), anyway he checked the signal level, which was good, and as a precaution he swapped my SKY box, which was great for about 2 weeks, thats when the problem started again, the same music channels and True Movies all breaking up and unwatchable.
Could anyone please give some advise on what this could be, and how to solve the problem,
I hope i have explained my problem well as its making me scratch me head.
cheers

Welcome to satellites,

This could well be DECT phone interference causing you problems. Unplug and see

Glad you got it sorted

For info purposes only,the DECT standard uses 10 frequencies in the 1880MHz to 1900MHz range. So if any IF frequencies fall within the range,interference could be caused.

For example the 11642 tp is using the 9.75GHz LO giving an IF frequency of 1.892GHz , which is almost right smack bang in the middle of the DECT cordless phone frequency allocation.

Good info Robbo and can be made worse if low grade cabling is used or a poorly terminated IF connection into the receiver.

mmm,I never quite understood how the DECT phones can cause interference as the cable is double screened, within some cases up to 110 dB isolation,but obviuosly it still gets through somehow.

I have DECT phones galore in my house and never had a problem.

 

[satelliteman]

Me neither

Maybe only certain model digiboxes are affected.

Yes, I've had it a couple of times, the interference appears to hit the box itself, as changing to another digibox can sometimes cure the problem.
