My IC7000 is mounted under the driver’s seat in my Kia Sorento and in various vehicles before this one. The radio always runs with the temperature gauge in the cool end of the scale, even after many hours of receive operation. Only rarely have I seen the temperature rise half way up the scale after transmitting but with no long rag chew overs! There is no additional cooling at all. The radio only feels slightly warm too.
I wonder about any bias settings ex factory on the PA could be a problem as many report how hot the radio gets when on receive.
The same problem was reported on the Yaesu FT100s as well but again, mine never got hot, just slightly warm. It still runs fine after 16 years.

It seems to be normal for the IC-7000 to run hot to the touch. Mine is also installed in the open on a cabinet and gives off a surprising amount of heat, even in receive mode only. I have decided to relax unless the inbuilt thermometer starts expressing concern.

Re: [IC-7000] Strange Behavior on 75 Meters

I get RFI problems with my 7000 on a /mm installation and here are my
observations. There are three different problem areas.


I should explain that my installation uses a diplexer to combine all
bands onto about 7m of coax and another to split 70cm/2m/6m from HF. I
use the water, a helical counterpoise, and 17m, and 20m quarter wave
counterpoise. There is an SGC auto tuner powered from the 7000.


1. RFI via the coax screen - this causes the rig to switch off on SSB
transmit.
2. RFI on the audio.
3. RFI which raises the indicated SWR at the rig and reduce the RF power.


The VHF and HF aerials are less that a metre apart!


1. is cured by a number of beads on the VHF coax close to the diplexer.


2. and 3. is reduced with quarter wave counterpoise on the affected
bands. Whilst the cause of 2 is obvious I'm have no real idea about 3
and I've not seriously investigated this yet as I need more ferrite.
I'm minded to try some ferrite rings along the 7m coax to see if RF is
being induced into the centre core in this manner.


Other observations of interest are that the cheap ferrite available from
rallies and ebay are just about OK on 40 metres and fine on the higher
HF frequencies but useless on 160m and 80m.

Hello,

when there is back HF (hf electromagnetic field near the IC7000),
you have this behaviour. So the problem is the setting of the antenna.

Perhaps it could be electric current of sheath and you could stop it
with ferrite (for me 10 clips'ferrites) on the coax near the AT-100.

If the antenna is too close, move it away

Of course, first, you have to verify the ground of the installation...

My 7000 acted strangely this morning. I hope someone can provide some
clue as to what may have been happening.

I attached an Outbacker OB8-tri mounted car-top on a mag mount to my
AT100-PRO, and the tuner tuned it. When I attempted to transmit, the
mode changed from LSB to RTTY about 1/2 second after I pushed to talk.
When I disabled RTTY, it switched to FM. After disabling FM, it
changed to my 60 meter frequency and USB.

Any ideas what could have been happening? Thanks,

I live in Africa on the coastline, where we get very hight temperatures and high humidity
levels. I have owned 5 IC-7000’s, and still have 3 of them with me now. I operate them
mobile with the main body under a back seat.
I have only had one failure in one of my 7000’s - and that happened right after I turned
it on and it was cool to the touch - ye it fried the driver…while the radio was in receive mode.
Sure these rigs get warm to the touch, but nothing they can’t handle. I bought one of those
external fans that power off the IC-7000, but rarely use it now.
I think a bit of common sense is all that is required. Using RTTY or AM or one of the other
digital modes that puts the rig into TX for an extended period, needs careful use, drop
the power way down, and yup an external fan would be good. Keep enough ventilation
around the radio. But for general SSB and CW operating….the radio is just fine the way it is.

My 7K  went into self destruct while in receive mode.  The radio was being used in a remote base application and was powered on 24/7.  Fortunately my wife smelled it and shut it down, and Icom did repair it under warranty.  It was and still is sitting in the open on a desk-top.  That was almost two years ago and the radio has been working flawlessly since.

Re: [IC-7000] Heat

Steve Agee
 

Apparently so, Rich. I have one in the car and one in the house. With them just turned on and never transmitting, after an hour or so, the temperature scale usually hits the first red segment. I suppose that is why lots of folks do a fan modification to keep the fan running all of the time. I've never done it to mine, at least not yet, anyway.

The solenoids on the injectors will need a fair bit of fast-rise-time current, so they'll be a good source of RFI.
