Well, you are overreacting to my posts ... I did propose to check DECA boxes temperature for now.
As I posted there appeared to be three indicators that something was amiss:
1. Video break up and pixalation during clear days/nights. ( I can't be sure this was caused by the deca connector going out)
2. When turning on the tv there would be the notice that "communication with the satellite was lost", but that was the only indication as the video was fine and the buffer full.
3. Consistent loss of home network connection.
In that order. It was about a couple of month between item 1 and two, about a month between 2 & 3, and a day between 3 and the combustion.
In the words of the great detective: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth."
So I would first assume that your problem might be at the satellite dish or a connection. Have a tech come out and check the alignment and connections.
If that is ok and you still have issues you can switch deca units (if you have more than one) and see if the problem follows the unit in question, maybe have the tech bring out a replacement when they are going to check the dish.
If the problem does follow the unit then I would call Directv and bypass the script talkers and talk to a real tech. I'm sure my issue has made the rounds.
Well any update on this?
Still smelling like a sh&$&% !
I had 3 DECA units installed about 1 month ago. I saw this post and just checked all 3. They are very warn at the end where the coax feed is attached. Now I'm concerned.....
If it's not on the pigtail to the receiver, the warmth comes from it being a 1 milliwatt RF transmitter.
I don't think 1 mW will rise the temp to warmth status ...
Do you have one to know/feel?
Since I have, it's fairly clear.
By law of thermodynamic and Ohm's law... the very low energy will dissipate to surrounding air faster then produce the temp. Try to make an experiment - get a resistor and power source - calcualte it for say 5V: P=I*U=U*U/R = 25/R=1 mW, where R=25 kOhm. Now tell me what temp the resistor will be ?
The output connector on the white DECA is the heat sink, and gets warm.
The WCCK is larger and its output doesn't get as warm, but is warm.
I'm sure it's the law of thermodynamics, but doubt it's Ohm's.
For generating the calories - yes. It's P [1mW], and try the 24 kOhm resistor (I'm sure you'll will not feel it warm ).
My 3 deca's are warm. Here's a link where some users find them very warm.
"the power source" needs to be RF and just like a power meter that uses a thermistor, heat is generated.
The DECAs use the input connector as a heat sink. The WCCK has more mass so its input isn't as warm, but the unit overall feels like it too generates as much heat.
Too bad this can't be quantified.
What is "too warm" for one person may not be for another.
I've never found any of mine to be "too warm to touch", but yes they do get warm.
I setup a couple of DECAs to see where and how much warmth comes out.
I don't find ANYTHING that would relate to the original burned up DECA here:
Just throwing my 2 cents here . . wouldn't this just be a short on the coax of the DC supply from the HR to the DECA . . . what size fuse is in the HRxx supplying DC to the coax port?
Nor do I. My DECA is warmest in the middle of the bottom side (near where the shortest arrow is). Both ferrules are warm, but not to the point of being difficult to touch for extended periods.
Folks who stack components are literally playing with fire.
There is no fuse, it would be a regulation chip what is monitoring a current and will shut it off if it goes high than 1-2(?) A.
I'm very skeptical about the "1 mW" power, it must be more than 1/2 W to get the box warm. Perhaps it's DC circuit , not RF as VOS mentioned.
Who have it open ?
