Hi guys,

I'm sure you are all aware of the problem that plagues Sky Digibox users on 19e/13e etc: the box sometimes loses channels stored in the "Other channels" section.

After much testing (I have too much free time :D) I have discovered it may relate to the signal strength/quality.

Basically in several tests, the box is a lot more likely to lose the other channels if:

a) the signal quality/strength is low
:cool: If you add more than 30 channels (I would say 30 is the safe limit)

Try it for yourselves, my digibox actually refused to lose the channels when I had about 90% signal quality- no matter how hard I tried :D, but was more than willing to lose channels nearly every time it went into standby with only about 30% quality.

For this test I used a variety of channels on 19e. :D

Id say it was more liely to be a bug in the memory handling in the box
Probably the case, but for some reason, a stronger signal/quality would appear to help the box retain channels..

is there any simple way to hack a sky box to make it more of an FTA receiver?

Not that anyone knows of...

Although if anyone else knows different, feel free to correct me :D

Ive got a rock solid signal off an old 60cm round dish, and my box still wipes the other channels if too many are stored. 30's about as far as you can go safely. I wonder if the number of other channels available to safely store has gone down as more and more channnels have joined the epg?

Thats correct. You cant play around with Sky boxes as the rs ports on the back are reckoned to be s/w disabled. Ive never heard of anyone getting anything worthwhile out of the port

Shame really...it would be a cool project if someone did have the skills to reverse engineer the boxes.

There has to be some functionality in the rs 232's as isnt that where the gamepads clip into?

Isn't it a complete waste of energy though, aren't they pretty useless as a receiver anyway?

They do what they were designed to do brilliantly. Which is

1) giving multiple channels to Joe Public at minimal hassle,
2) extracting maximum cash from his wallet at the same time
3) making Joe forget about the endless possibilities we know and love elsewhere in the heavens, as the bloody things are so crippled as to be effectively useless on anything apart from 28E

I would hardly say they are TOTALLY useless, I have 30 of the best 19e channels programed into the "other channels" section, and they never disappear unless the mains power is pulled...

I still want a new FTA box soon though :D

if i could find the source code etc for a given box, it would be an easy fix, (probably!) re-organsing the channel storage capabilities, turning it into an FTA receiver: going no where near the decryption stuff. however i guess this kind of code is well guarded because of its proximity to videoguard/NDS. the reason i think it could be a good little project is that i note the odd digibox goes for as little as £20 on eBay, it would bring the cost of FTA DVB receivers down. mmmm...
