"GeorgeF" wrote in message nk.net... 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..... George http://www.MilAirComms.com 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... :-) Michael |

I don't recall off hand if that was standard, or an option. I run my Drake R7 here on 12 volts due to having some diodes in the power supply failing in years past due to heat, but even the R7 does not run hot. The R7 hits the trail to Ohio tomorrow for a tune up. (This one has never been sent out by me for a tune up, but it reads just slightly off on the readout.) I'm looking forward to using it a bit more this dx season, and maybe snagging a few of the Indian regionals I don't yet have. dxAce Michigan USA |

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. dxAce Michigan USA |

I encountered several of them and never noticed that to be the case. Warm yes, hot no. dxAce Michigan USA 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. BDK |
