Does anyone know of an alternative supplier of the OPC-144 in Europe please, and can you use a CAT 6 cable for the mic extension?.

  Make yourself a rapid disconnect cable from the parts of the first one.  If the connectors are good, it should be fine.

I doubt that this experiment is going to solve your problem, however.

Have you tried doing a CPU reset (page 25 of the user manual)?

Hello

I bought the OPC-1444 from a local normal shop (not online)
I did not know that there are different versions for EU and US
All the photos I have seen on the internet about this cable are the same
I could not see any cable with ferrites
I only new that there are different versions for the DC cable OPC-1457(R) with the "R" for EU containing some EMC filters that the US non-"R" does not have.
Maybe you are talking about this cable to be different between EU and US ?

About the old separation cable I think i will cut the connectors form the ends and try to solder UTP or FTP cable to make a separation cable a little longer than 5m (16ft).
I hope it will work.


Re: [IC-7000] AT-7000 failure

Ing. Juan Carlos Parra
 

Dear sirs.

I have a AT-7000 and a IC-7000 xcver. Both works fine during last 3 years.

Now, suddenlly the AT-7000 do not start to tune.

Sintoms are:


· When push the Tuner/call button in the xcver, the tuner light blinks and turn off inmediatelly. No relays activity on ATU. No TX.

· Connector pins 3 & 4 are +14V and 0.

· Pin 1 (key) is +3.29V

· Pin 2 (start) is 0 v always.

· When I push the reset button in the ATU by 2 seconds, at the release Tx began shortly , led blinks and later turn off.

· On Quick setup the 3 tuner commands are in default value.



I wish to know if the problem is in the ATU or in the Xcver.





Best regard and thanks for any help in advance.

The OPC-1444  is the head  separation cable,  there is no difference between any version, they are all the same.     it is to remotely mount the head of the rig.

I believe the only differece between the EU and US version cables is RFI ferrites.  The wiring and pinout is the same.

Hi there guys, sorry I haven't been active here of late,  The separation cable issue is an old one and it started with the Ic706, like everything else with ICOM there are at least two versions of the cable, both have the same reference number, but one is designed exclusively for USA and Canada the other is for European (EU) countries.  If you bought it over internet it is most probably a USA/Canada version, and as you are in EU you would need the EU version.  WIMO.de might be able to supply the correct cable.



This will not be much help if you have already splashed out on the cable, but I think it is the reason why you can't get it to work.

Re: problem with separation cable

Well that is what the technician from Icom Representative asked me as soon as I told him what is going on.
I bought it (and payed it!) to be an original cable and not like a cheap chinese copy.
Also the package was exactly what one would expect it to be (like all the photos I saw on internet).
But I can't really know for sure if it was an original Icom cable or not.


Re: [IC-7000] Re: problem with separation cable

Just out of curiosity,  are these actual Icom separation cables? Could they be some kind of aftermarket knock off?

Hello
Finally I went to the sellers shop and got a new cable at a great discount price.
Unfortunately he did not accept to replace the old one for free
So I still have it and I will do the test between the pins that Malcolm said
Thank you for your suggestions

Re: Accidentally Shorted Radio with LDG Tuner Cable

Steve W3AHL
 

You probably fried one or more of the RFI filtering components on the DDS board between TUNER pin 3 and the main 14V bus.  Get a Service Manual and look for EP1003 (SMT ferrite choke) and L962 &L963 (270uH SMT inductors).  They are in series with the 14V bus and won't handle much current.  The parts probably cost less than $5 from iCOM (including shipping), but required a steady hand to solder in place.  

The inductors are on the bottom of the DDS board (which is facing up when you remove the top cover) and are easily checked with an ohmmeter.  EP1003 is on the other side of the DDS board, but can be checked by just measuring the resistance from Tuner pin 3 to L962/L963.  I suspect the two inductors failed first.

Hi I have a 7000 cable works fine , it only stands to reason if the head is on the body and works ok when it must be the cable maybe hopefully the connections from end to end are good . So take the guy up on his offer to test the cable .
I also use an automatic turner on my setup works good on the ic7000 .
Let us know how you made out with the problem .

The screw is the one that came in the package of the cable.
I will have a look at it to see if it has removed color on the underside.

Currently I do not know anybody else with ic-7000 with or without separation cable to try exchanging gear and test.
I'll see what I will do about this! :)

Unfortunately I do not have neither equipment nor knowledge to open the unit or head and analyze the display signal.
I could try hooking up the rear video out to my TV for testing but I would have to find a desktop power supply first (or get the tv close to the car - not very easy!).

My IC-7000 was a used one but i know the previous owner and as far as I know it works fine.
The cable was bought by me last month as new one (I did not have the 7K yet so I could not test it at that time).
I already talked to the seller of the cable and says that if it was faulty I should have returned it earlier! (doesn't the cable have warranty?)
But he told me to go to his shop again (with my 7000 because he doesn't have one) and we will test the cable together and see what we can do.
I guess this is my last hope currently!



Re: [IC-7000] Re: problem with separation cable

Hi, As you have tried all the normal tests on the cable, try this-----

Try ohms between,  pin one at one end and all the others, then pin two and all the others, then pin three and all the others.

I know you have tested end to end but this will find if there is a short between wires.

Good luck  Malcolm G3TCG.


Re: [IC-7000] Re: problem with separation cable

Paul Williams
 

Hello and sorry to hear aboit your 7000 issues. Sounds to me like the issue is definitely associated  with the separation cable since it sounds like everything seems to work fine with the  head connected to the body. I'm currently waiting for my 7000 to come back from Matt at SARTS in Michigan. He found a couple developing issues with it and repaired them at a very reasonable price. Good luck.

Paul

Hello again

I continued the tests with the separation cable
I tried wiggling the separation cable and walking around with it to see if that would cause anything like display flickering or something like that but nothing changed.

Then I found out that if I have the microphone connected on the head, sometimes (not always!) it is not working (the mic).
The buttons cannot be used to enter a freq or anything else and also PTT button is dead.
So this means that the problem is not only the head display but it's something more generic having to do with the communication between the body and the head.
Backlight of the mic buttons works always with or without separation cable.
Mic , PTT and buttons work fine without the separation cable.

Also there was a time that the display was behaving better with just a little flickering on RX and TX but remaining readable and without negative colors.
I could not guess anything being different from other times at that specific moment other than having the 7K powered on for more minutes than other times.
At that time I tried testing different values for the "LCD flicker" menu option but other that the screen bec oming more or less "greyish" depending on the value the flickering on RX/TX continued.

Do these facts ring any bell to anyone about a possible cause?
Might there be a possibility that all these problems originate either from RFI or Input Voltage problems?
