**vmd1916** · 5th January, 2009, 02:22 PM

hello guys just got dm500t up and running yesterday with signal lock but today for some strange reason snr fluctuating 61% to 100% has any one seen this before , was up on the roof today despite frost,at ariel does not seem to be the issue,have digivox t running in other room with no probs, plugged out to see signal increase on dbox alas no difference,am i missing something.
i read devilfish recomending a booster to increase signal on another thread,but not sure i can do this with a mmds set up which already increases signal ,any advice greatly appreciated
thanks guys

sounds like a loose connection or ur run to dreambox is too long, but if ur in a weak signal area u could try changin ur aerial power supply the standard one is 18v... if u use a dreambox one its 24v and this will give u an extra boost as i had same issue wit 2 boxes changed psu and now i have 4 runnin ok all at same time.

thanks red devil i have a 24v here i will put it back on and try again,i moved ariel to its optimium position yesterday,the snr is just bouncing up and down as i said 60% to 100% very quickly ,is this normal for box with weak signal or does it snr just sit there on what ever signal it recieves?

I've had this sometimes for no obvious reason,

found that some images for the 500t run the tuner better than others,

if the problem persists, try reflashing, with the same image or another one to compare, the Pli ones seem to help more with signal issues . . . .

ok guys i put on the 24 volt mmds power no difference,ok so i will reflash box with dk1.1 20.08.2008 which is already on,is this recent enough or maybe its not right for my area ch***s kildare area
is there another image you guys could recommend you see not familiar with pli image i done search here but nothing turned up!
this is great site and really have learned a lot from guys here
