Hi J.D.:

Correct there is a relay driver (Q700) to pull the low side of the relay coil (RL701) to ground. The high side of the coil and the N.O. contact is sourced through the front panel fuse, which checks OK.

No matter what the state of the power switch, POWS never goes low, to turn on the relay driver and therefore RL701. Seems like Icom (in my mind) got the signal names backwards: POWS should be the switch and POWK as in 'K' for the relay, but they are opposite. No big deal, just confusing.

It seems as if the CPU board is brain dead. Tonight I will look at the XTAL pins with a scope to see if the CPU is getting a clock.

Another interesting observation is that there are tiny dots of corrosion, along the top row of pins on the CPU and a spot to the right side of the CPU, extending to a small group of surface mount components. I'll try to clean up those areas better with a fiberglass brush and maybe take some pictures. There are ventilation slots on the CPU board shield that line up with the ventilation slots on the top cover. Brilliant! I don't recall anything splashing on the rig, but for the 5 years it was mounted to the floor as a mobile rig, who knows.

Re: IC7000 No power on, no relay click

 

Good luck to all on reviving your IC-7000.
I have had to bring two back to life and had to trace all of this, but that was a while ago.
I believe that if you have a +3.3 volts on Q700 the relay should pull in and power up the radio.
If not then there might be a bad relay etc.
I think you are on the right track.

Hey To All,

Have here the same problem...J.D. if the relais dont go to ground (via q700 if i be right) you dont have the possibility to put the rig onn!
Its a great problem..there is only the  14V comming from the allimentation...past the fuse in the front..then going to the regulator on the cpu board as "HV" ...after the regulator you have the 3.3v vcc for the cpu.
There is no more life to find...on the rig...solong the cpu give his orders to pull the relais and give the 14v free to the other part of the rig...
I hope to bring life again in my rig..snif snif...

Re: IC7000 No power on, no relay click

 

Steve 
The 3.3 volts out should (I think) go to a relay driver as the 3.3 should not directly activate the relay. First I would do a complete reset (If possible) and see if that makes a difference and then I would go looking for the signal path from the CPU to the relay driver. Also the +12 volts to the circuit that has to be there for the relay to pull in. 
Check the fuse behind the front panel as well.
I think that the radio "remembers" on-off state to the relay so it may be " stuck" in the on mode.
I couldn't find the relay in my perusal of the schematics just now, working from a defective memory of working on the radios in the past.


IC7000 No power on, no relay click

Hi all:

Pulled the radio out of storage and attempted to power up the rig and it is completely dead. I have verified 13V at the PA board and 3.3V at the regulator on the CPU board.

I traced the PWRK signal to the CPU and I see it pull down to GND from 3.3V when the power button is depressed. The POWS signal that drives the power relay is high at 3.3V and never changes state.

Most of the power on problems that I have read about with this rig have to do with the power relay clicking, which is different than the way this rig is operating,or not operating.

Re: IC-7000 First Time Use

Hi Doug,

I use the RT Systems Cable for programming and rig control (CAT functions)

My installation leverages a Rigblaster PnP (on it's own USB port) - where the PnP plugs into the accessories port on the IC7000.

Works perfectly - using all Ham Software (including Linux and OSX).

I should have added…

You can use this cable for the CI-V too but not with the RT Systems software. Their cable is proprietary to their software.

Re: IC-7000 First Time Use

Doug,

 

You can buy the interface cable for the Signalink for the IC7000. Direct connection to the data port.

For the CI-V, the CT-17 isn’t necessary unless you want to use the DB25 connector to connect to your computer.

You can use the RT Systems cable to connect the CI-V to your computer too using the USB interface.

 

For cable connections go to the ICOM site and download the manual.

Update from WWW,VE2DX,COM

Hello Gang!

Here is a short update from WWW.VE2DX.COM and what we been up to! 

Keep an eye out for the soon to be released CT17B-6USB and CT-17B-6USB-Plus that offers a USB port, 5 CI-V ports with a detachable Mini USB cable.  The CT17B-6USB-PLUS also has a pair of outputs on a 1/8 jack, controlled by RTS and DTR that you can use for PTT, CW RTTY FSK, and other digital modes this addon was being asked by many for a while well it will be available on WWW.VE2DX.COM in January 2021...

Our new 3D printed cases for the CT-17B and IAB family of products were made a lot better with indented lettering and cooked in white paint to make the lettering a LOT better.

On the IAB1 and IAB2 family of products, we added RF filtering to each pin.

The IAB1-13 will be back on popular demand in January 2021, the CT-17B and IAB Family will also have a GoKit packaging where we will NOT be using 3D cases, but instead a simple ShrinkTube approach for the whole board, making it easier for the user to integrate the CT17B or IAB in a rail-mounted system or behind the cover. pictures will be posted on WWW.VE2DX.COM.

 The CT17B Bluetooth and USB products will now Identify themself clearly as a CT-17B in your OS thus making the installation and troubleshooting easier.

Well we have been able to confirm via ICOM documentation that the IC-705 should be able to talk to the CT-17B-6BT Bluetooth CI-V hub, offering the possibility to the user to remote control other ICOM radios or devices (ICOM and NON-ICOM CI-V compatible!) everything is pointing to the success we are waiting for a loaner 705 (I still want to get one just need $$$$$$$) the loaner should be here in January 2021 if all goes well and as soon as our testing confirms our approach is valid we will document the process and publish it! STAY TUNED to WWW.VE2DX.COM.

New videos will be published on our youtube page https://www.youtube.com/user/ve2dx

Our IMK keyboards are finished development and even been assembled! They are working GREAT!!! Just having a hard time making the cases in 3d print!
I am looking at going with custom metal cases from the EU that would also offer some shielding... I Will see many people are awaiting these they are really great! The worse part is they WORK GREAT just don't have cases yet :(

Our 2X6, 1X6, and 1X4 remote antenna switches are working GREAT! especially with the 2X6 Interlock board!  I have a setup in my shack of two 2X6 with interlock face to face with BPF between them and a third 2X6 remote in the tower to select the antenna, finally, a 1X4 is used with the 80/40M directional 4 element sloper to select the antenna direction.  All of this is driven by a 7300 and 756ProIII.

We are still working on other stuff like the IAC (Atas 100/120 automatic controller), the SL1 SGC smart controller, and SOO many others its crazy...

So please keep an eye on WWW.VE2DX.COM our Facebook page https://www.facebook.com/VE2DX or our youtube page https://www.youtube.com/user/ve2dx

Re: Current drain while off

Steve - many thanks for the information. Most helpful. 


Happy New Year to all

Re: Current drain while off

Steve W3AHL
 

Tom,

The current draw when the 7K is off is about 20 ma.   It bounces around some, but that seems to be the average current.

Also, there was a question about the coin battery used for the real time clock circuit (not other memory functitons).  It is a rechargeable manganese lithium battery, not silver oxide, (Part # ML920S/F9D) which is charged as long as power is supplied to the radio, even if it is turned off.  The batteries in my two 7K's lasted about 10 years.  I only use it to display UTC time.  They are available from Digikey for $2.16 each (Panasonic part # ML-920/DN).  It is soldered in with attached tabs, but easily replaced.  Just be careful not to short the battery leads together.

Steve, W3AHL


Re: Current drain while off

Donald McRoberts
 
Edited

Here is an excellent video that shows how to change the battery. I've done it and it was rather easy to do. Just be careful to use good soldering techniques and handling of the components as they are removed and replaced.

Also, I do not remember losing any of the settings when replacing the battery. It's been several years since I did the replacement.

Re: Current drain while off

Max
 

But wouldn't it also lose the settings as soon as you remove the old battery? You can't leave the rig powered up while replacing the battery because it requires too much disassembly.

To bury a battery deep inside a radio is asinine in my opinion. It could have been moved to a location where it was accessible by removing a cover and the battery should have had a plug on the end so no soldering would be involved.

Since most would have to send it in to have the battery replaced, this was likely done to generate more revenue.

When your clock resets every time y0u turn off your radio you will know that the battery needs replacement.
It may be that the battery does not keep the frequency memory alive. that may be stored in flash memory.
But the battery does keep the clock running.

Re: Current drain while off

 

I believe that I was wrong and the battery may well be just for the clock.
I do know that the clock will reset every time the radio is turned off is the battery is dead.
I believe that the frequencies stored etc will be maintained in flash memory.
If my recollection is correct.
Sorry for the misinformation.
The battery is not too bad th change and it lives in the small silver box at the left rear of the main board.


Re: Current drain while off

Nope!   And changing the battery will dump your info.
