I have an R-5000 which works great. However I'm wondering from others who
own or have owned an R-5000 if you're gets hot? After being on for hours
mine gets so hot you "almost" can't hold your hand on the top cover. Mine
has done this for years and hasn't yet affected the receive performance but
just wondering if this normal.

My other HF rigs don't get hot (JRC NRD-525, Yaesu FT-847, RadioShack
DX-394 or Kenwood TS-520) all of which are one 12-20 hours a day.....

A close friend has an R-5000. He has confirmed that it runs way hotter then
his R8b, but not so hot that you cant touch the top of the radio. He keeps
his radio on a large counter top and said that his cat likes to sit on top
of the radio when its on because its warm... :-)

The suggestion to run it on a seperate 12 volt supply is a
good one if it has the 12 volt option. I don't recall off
hand if that was standard, or an option.

DX ACE,

The DCK-2 DC Operation Kit is an "Option" for the Kenwood R-5000.
The 'kit'has two parts:
- Internal Wiring Harness with two Plugs; one Plug to mount on
the Radio's Rear Panel for 12 DC Power Input; and the other to
plug into a PC Board.
- External Wiring Harness with two Plugs; one to plug into
the Radios Rear Panel 12 DC Power Input Jack; and the other to
plug into the car's Cigarette Lighter.

The Kenwood R-5000 does run Warm to Hot when used for a few hours.

Really? Mine never did and I had it for several years. I guess our definitions of
'hot' do not concur.

Well, all I can say is it was unpleasant to touch for very long, and it
was the hottest solid state receiver, by far that I have ever had,
including my ICOM R7100 that also ran very hot on 117 volts..

Yeah, I've heard that some of the ICOM's indeed run very hot. But I can't figure out why
anyone would say that an R-5000 ran so hot that it was unpleasant to touch. I
encountered several of them and never noticed that to be the case.

Warm yes, hot no.

Of the three I have played with, mine and two friend's R5000s, all ran
equally HOT. Hot enough to be of concern over time as the inside temp
was also much warmer than normal. The very first mod I ever saw for it
was moving a couple of regulators to the back panel and adding a couple
of big heatsinks to make the inside temp drop from (I think, it was a
long time ago), from 130 deg F+, to less than 100 deg. I just put mine
on 12V, it was already set up for it when I bought it used. If I hadn't
had it set up for 12 volts already, I would have tried to find the kit
to do it, or done the mod. I'm amazed the heat didn't kill them within a
year or so. You open the case and touch those regs and they were hot
enough to burn you.

I was offered 40 bucks more than I paid for it a couple years after I
got it, and off it went.

My R-5000 runs hot as well, the first few years I had it I used small a cooling
fan on it. Then I added a 12VDC power jack on it and problem was solved. The
Kenwood kit was no longer available so I made my own. Just a bit of soldering
and adding a power jack and a mirror image power plug. I run it off a 3 Amp
regulated power supply from Radio Shack. Bruce
