Re: Current drain while off

 

I had three of them and never noticed, but then I did not run them mobile very much.
I suspect that the parasitic loads from the car itself are in the same order of magnitude.
I think that the radio just keeps the low power mode on the CPU alive so that pressing the power button is recognized by the radio and pulls in the power relay.
If you are to be gone for a long time you could just pull the + side fuse to kill the load. That would keep the contacts clean as well. 
Adding a switch is probably more work than I would do and adds another point of failure.
I sold all of my IC7000s and bought an IC7300. That radio is great, but I miss my colorful 7000 and its HF,VHF and UHF.
I bought a FT857 (dead) and resurrected it for the combo, but it is not a 7000.
Good luck and best regards,

Current drain while off

Tom
 

Hi

i have two IC7000 radios and I love them. I have one mobile in my car and it’s just great. However, I recall reading somewhere that even when the radio is “off” it’s still drawing a small current - enough to be a problem if the car is left standing for a length of time. I’ve had multiple times when my car battery died. I’m military and often away for a while. I do have a trickle charge solar panel that helps avoid this. 

So, does anyone know the current draw for this radio in its off position? 

I’m going to fit a switch into the power lead to isolate the system but it is useful to know. 

Happy New Year.

Re: No RX or TX after changing frequency

 

PWK goes to the lLOGIC unit via J651 to pin 135 on IC1302.

It is possible that at that point you have another problem in the head. When the control head gets power the cpu sends a signal that it is alive and ready to the main cpu where the relay is not dropped out.
I suspect that a second problem was created when working in the head.
I believe the PWK signal makes a ground that pulls down the device that initiates the POWER ON SEQUENCE.
I would trace that signal to find out why the relay is no longer pulling in. PWK goes to the  IC1302 to initiate turning on.
The control head has no voltage on it until the relay pulls in.
The voltage present should be the voltage pulled down by the power switch. Check for that voltage on the switch at the transfer jack pin 2.
After the relay pulls in 8 volts at pin 1. 
I hope memory serves and it helps you fix your radio.

Re: Ic7000 no power on

He tks for the awnser..
@Peter not that problem everything chequed...problem somwere other..
@ JD I have the vcc on the cpu board buth no reaction when i push power on button..

to all C530 burned with burned place on the motherboard also..

so correct me if i have wrong..

we have a "HV" line and a 14v line  the 14v going direct to the pa's.. the HV line deliver the "lowtension" to the pcu via the ic1251..correct tension 12 to 3.3v..this tension giving the VCC for the cpu...
now if i push the power on then the pin 135 of the cpu going "low" via the r 1010.....normaly then the pin 107 of the cpu placed the Q700 low and so the relais closed and give the the thension the needed....correct???

so solong the relais dont close there is nothing thath can turning onn???

Re: No RX or TX after changing frequency

 

Just for the heck of it try changing the ribbon cables. at the front of the board. The cables are not expensive and are sometimes problematic.
I have not had this particular problem, but have traced signals all over looking for other problems. They tend to crack if they are bent over and pushed on.

Hi Mark,

I been a certain times not use my ic-7000 , last week when I try to turn it on ,  the ic-7000 response with click and click from the power relay and can not power on the ic-7000 , after I cleaning the contacts between the front display unit to the main unit , the click and not power on was get solved but have same phenomenon as you have had.
Not know if you have found the caused and get the problem solved now ?  If yes.  Can you please sharing me with your experience as my reference.  
 
Thank you ,

Re: Ic7000 no power on

 

When you have the click - click problem what happens is that the +8 volt regulator feeds the front panel unit with power and in the panel there is a 5 volt and a3.3 volt regulator that will burn out the resistor that feeds that 8 volt reg on the main board.
The CPU on the main board turns on the 12 volt relay and it has a few seconds to get the response from the CPU in the control head.
You have to have power the the CPU to activate the power relay.
IC 101 and IC 151 for the 5 and 3.3 volt in the control head.
If the 8 volt regulator is on line (no burned resistor)  and you  have 9 volts to the control head then check for the 5 and 3.3 volts on the board.
No voltage on the board the CPU cannot generate the data signal to the main CPU.

Hi Luc, which component have found burnt ? Before fix you have to understand way component burnt. Often  on front panel there are 2 condensators which they went in fault.

 

Let check on web, you will find a lot of documentations.

Hi,
so i have a problem with my 7000 , first i had the click click error.Control of the rig an i foud a burned C. replaced this one and  now nothing is hapend isf i push the onn button.
Have any one any experiance with this problem...

Re: IC- 7000 USB Driver Software needed

Greg Engle
 

What kind of cable are you using? And which driver are you talking about?

The USB driver for the Radio is at Icom JA and their radios require the correct driver.

If you’re using a cable that needs a driver (i.e. a USB to DB9 to connect to a serial port on the computer) there might be a driver conflict.

Subject: [ic7000] Temp always showing hot #all

 

I bought a 7K (after having been out of the hobby for 30 years) and it’s a great little radio BUT the temp gauge always shows HOT, even after just switching on.
also the fan always runs, even after just switching on, but this could be mod’ed as per some posts.
The radio is not hot to the touch and the rear heat sinks are cold (well, it’s been off).

<image001.jpg>

It’s been behaving but in the last few days the power output seems to upon keying FT8 - never used to do that.

yes, I run 100W on FT8 as I only have an inverted-V dipole and contrary to some comments I can’t “work the world” with that e.g can’t get to SA although have all other continents.

anyone have any idea;
1. Why it’s always showing hot
2. why the power output would fluctuate on keying

SWR is all below 2:1 on all bands except 30m but handled with LDG IT-100 tuner.

thanks
kurt

There may be a setting required for full, or half duplex, but I am so old I have forgotten and I can't look at my setup to see as my current rig is a IC-7300 and it is USB direct.
