Resolved my issue but created another!

Hi guys,

After some advice on here I went out and bought some attenuators but it turns out I needed a booster to get my missing channels. No big deal as the attenuators are only coppers.
Anyhoo, I'm really chuffed I finally got to the bottom of it, as after a bit of tweaking with one of these I can now get my missing channels (MTV, Bravo, Challenge and Discovery). In doing so though, the box locks up frequently now which it rarely did before.
Is this a trade off having to hike the signal strength up, or should I have bought the VSA-608C booster that Sherlock speaks of.
Is their anything else I can do to stop this locking up happening?

As well as the gain control, this box has a Slope Control, whats this for?

Thanks in advance.

Well done and unlocky m8!

Sounds like the stonger signal is causing the problems to me. I guess you've tried altering the gain down as far it can go, without loosing the channels again, to see if it stops freezing?

Yeh I think you're right,
I've had a situation where all that was missing was Discovery and as I thought I was onto a winner , I tweaked the gain just a 1/2 turn more to get these and done another scan. Could try turning 1/4 turn back. Dunno how sensitive these things are.
I could have left it at finding MTV which is what I was mainly after but you know when you're getting somewhere you just think...yer, one more turn and I can get the lot. :fishpair:
One thing I noticed, if I turned the booster too far on a new working channel (e.g. Trouble) the SNR would drop from 90-91% down to 67% and I would have to wind it back a bit and re-tune.

Any ideas what the slope control does? Didnt wanna fiddle now its almost their.

No idea what the slope control is for m8.

Sometimes a strong signal can have the same effects as a low signal. It's finding that happy medium.

Thought you were gonna say that. lol

Oh well, keep on tweaking.

Whatever this means lol...

[FONT=Verdana, Arial, Helvetica, sans-serif]Automatic Slope Control (ASC)

Obviously yours isn't automatic but you get the idea.

Slope control is for anyone that lives on a hill...... LOL
