dm500t signal issue, help please - MMDS

**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

i'm familliar with your area and the dk 1.1 or dw 2.1 are sound for where you are . . . .

**red devil** · 6th January, 2009, 02:26 PM

def try the same img as b4 in case u got a bad flash the first time but the dw is a good img too i have it on a box as well

**vmd1916** · 6th January, 2009, 03:30 PM

thanks lads i will keep pluging away , il try what you mention above ,i will try to reflash with null cable, earlier i just flashed while box on tv with cable to router.and i am running evocamd2.12
i will get back to you ,maybe box is damaged in some way
either thank you

**vmd1916** · 6th January, 2009, 04:58 PM

reflashed dk1 image ftp keys and scce files also but no change,where would i find dw 2.1 to try next ,am obsessed now

SNR isn't affected by keys or roms or an image, it's a measure of how much signal it can see over the noise in the feed. Only the feed itself affects it.

Unless the tuner is faulty. If you recently purchased it, contact the seller and ask to get it replaced.

i have it a while but thank you ,for ruling out other stuff , and others for your help

im in the exact same boat as you mate, was watching my 500t one night perfectly (have had it for 2 years) then one night it just started acting strange, i thought it must be the weather so i went to bed but it has been the same ever since. Im actually in the same area as you, kildare town and im running DW2.1 image.

i did at 1st think it was my down converter or power inserter but my subbed box is working perfectly

MY SNR jumps from 96 down to 20, back up back down etc every few seconds and i cant get picture now

Also my 500T is an original box not a clone

cant figure out what the problem is at all

if you come up with anything let me know

cheers

i will lad, but i have put a long time in on this box,
and have learned alot on the way with fellas here,
so if its gone so be it ,dont think anyway repairs in ireland

Hi lads, keep the heads up as sounds like yere tuners are goosed as devilfish said, one of u try and email the sellers for a price on 2 tuners and u might get a bit of a discount as ur in same area
