Should the wired DECA/CCK run hot?

The wired DECA/CCK the DirecTV installer put in this week is running pretty hot. Hot enough that you can't keep your fingers on the coax jack for more than around 5 seconds without burning them.

Is that normal? Seems bad for electronic devices to run at that high of a temperature...

Maybe it's sensitivity, but mine aren't that warm.
Warm YES, as each one is a 1 milliwatt transmitter.

Mine definitely is running HOT. Like I mentioned, if I put my fingers on the coax jack, they will get burned if I don't let go after about 5 seconds.

The box itself is pretty warm as you say, but the jack is hot. Just has me concerned about using it with that kind of temperature going on...

I had mine sitting on top of my H25 and it got extremely "warm / hot". I didn't think it would be an issue since the vents for the H25 were on the sides. Once I removed the CCK from the top of the H25 and let it stand alone the heat reduced dramatically it's still warm but defiantly not super hot.

The metal connector is the only real heat sink, so they get warm. I held my hand on mine [just now] and don't burn myself, but then I can hold on to fairly "warm" things.
Do you have a way to get a temp measurement?

Hi VOS,

Thanks for the explanation about the heat sink - that certainly makes sense.

I ended up unplugging the DECA unit last night as well as unhooking the coax and ethernet and let it totally cool down. After I replugged it in and let it warm up again, it didn't seem to be quite as hot as before. Maybe that is just my imagination or I'm now just more used to how hot it runs. I'll keep watching it though, just to be sure.

Anyone tried opening one of these up and putting a heat sink on it? I wonder if it would help?

I have the very same problem but my finger would burn after fewer than five seconds. Mine is sitting on my cable modem which also runs warm. After reading comments here, I will try moving it away from the cable modem and let it sit on its own. I suspect temperature will decrease but will still feel hot to the touch. It does feel like a waste of energy.
