Re: [IC-7000] IC 7000 tune button

Resonance doesn't mean that the antenna is matched to a 50 ohm load.  An antenna can be resonant and present a 10, 50, 400, 5000, etc. ohm impedance at the feed point.

I don't know of an easy way to disable the tune button, but Tune Power Output is adjustable using the Service Manual procedures.  It is normally set to 10 watts, but can be decreased.  I've never tried to see how low it will go.

If you have a SteppIR why do you even have a tuner in line?

Resonant antennas don’t need one.

Gee???? r norris, what a kind and helpful reply... don't have anything
better to do today?!?!

I don't know how to disable the tuner in my IC-7000, but I sure know how
to spot a show off!

Best of luck with your 7K!

My fat fingers occasionally bump the tuner while the amplifier is on line thereby pumping a few hundred watts into a tuner that recommends nothing over 25 watts for tuning.  I managed to fry the LDG.  


If not electrical then perhaps some sort of cover or way to remove the button. Comments - keep em clean.

Yahoo groups have continuously had problems, since “Neo” was introduced, with long delays in posting, poor response, missing content, and loss of user features. They are also attempting to force you to use a Yahoo email address.

Groups.io dose not have any of these problems and as a moderator there I can state that the management tools are much better.

Has anyone heard anything about yahoo groups becoming an obsolete product of Yahoo now that it was acquired by Verizon? There seem to be missing data already from the files section of some yahoo groups.

I am also member of the Kenwood D710 yahoo group and they are talking there about migrating to other services to avoid downtime and data loss. They are mostly taking about groups.io, created as they say by the former creators of yahoo groups that provides easy migration from yahoo groups to their service.

Perhaps we should take a look at this an consider whether we should move elsewhere or not.

YahooGroups could last forever or it could shut down any time. Support from Yahoo pretty much ended a couple years ago and now that Verizon owns it no one knows what they plan to do.

Why on earth do we need to transfer to a group based in the British
Indian Ocean Territory.

I see a bit too much facebook type speak on their homepage.

Most importantly I can see nothing that says there is an email delivery

again this plan.

Paul,



Having repaired many 7K's over the past 11 years I can confirm that ALL of the flex connectors DO INDEED HAVE a release clamp that must be pulled up to release the pressure on the contacts before removing the cable. Failure to do so will usually pull the plastic stiffener/alignment piece off of the back of the cable.



The clamp must be in the UP position before reinserting the cable, then pushed down flush with the connector top, insuring that the cable is fully seated in the process.



The ZIF clamp is a very thin brown plastic "flange" that is on both edges and the back side. I use a smal dental pick to pull up each side about (less than a 1/16") to release it.

As a general rule, most "flex" style cables have gates on the companion connectors that must be raised to release the cable. Failure to do that will result in torn-up cables. The "gate" is usually a small plastic "cap", that is usually a contrasting color, on one side of the cable entry point that can be lifted at each end to free the cable. On re-insertion, you want to push the "gate" back down to capture the cable and move the contacts into position.

Hello,
Removing the PA board or analog board requires removing the two ribbon cables at the rear.
After sitting there for ten years they won't like to be pulled out.
Easy to destroy them. Parts of the solder coated contact strips come off, and then later when re-inserting them, they fail completely.

Before re-inserting the cables put some contact oil on the ends.
I used non-oxidizing weapon oil sometimes, when no contact cleaner was available.

I couldn't remember for sure how they worked, that's why I stated "general rule". The first and last time I was In the "innards" of my '7000 was right after purchase to check for heat sink compound on the PA and to MARS mod it. I had to remove the ribbon to get to the PA buts it was too long for details! HI!
Flex circuits are not new to me as I had a smattering of aerospace exposure as well as in communications. Careful is the watch word for sure.

Re: [IC-7000] Source for IC7000 ribbon cables.

Steve W3AHL
 

You're correct Paul, the boards you sent photos of don't have ZIF clamps.  I looked at at 2012 unit that I have on the bench and it doesn't either, except in the display head, per the photos I sent to you.  They have brown clamps that are easily released so the cable removal and insertion requires no force and doesn't damage the cable.  

My two personal units from 2006 and 2010 had them in the main unit also.  I don't know when they changed or if they mixed vendors along the way.

I think I'll try to order more replacement cables from Icom to have on hand, since they are bound to come in handy some day!

Sorry for the confusion.

Paul,


Having repaired many 7K's over the past 11 years I can confirm that ALL of the flex connectors DO INDEED HAVE a release clamp that must be pulled up to release the pressure on the contacts before removing the cable. Failure to do so will usually pull the plastic stiffener/alignment piece off of the back of the cable.

The clamp must be in the UP position before reinserting the cable, then pushed down flush with the connector top, insuring that the cable is fully seated in the process.


The ZIF clamp is a very thin brown plastic "flange" that is on both edges and the back side. I use a smal dental pick to pull up each side about (less than a 1/16") to release it.

No clamps there.
See attachment.
(Hope it works)

I doubt these will come through but, I have tried to attach 3 pictures of IC-7000 connectors on the MAIN unit and the DDS unit. None have retention clips. Because they probably will not come through the reflector, I’ll forward them direct to you so you can point out where they are.

Perry,
I can tell you for a fact most Icom flex connectors are not a form of ZIF connectors. They do not have clips, levers, gates or any external tension devices. If you are unfamiliar with them, removal is risky, re-insertion is an order of magnitude riskier! In IC-7000's, there are two high density flex cables between the main unit and the PA unit. I see them damaged all the time from erroneous alignment when inserting them into the main unit connectors. Worse, if they come out of the PA board connectors, you have to remove the PA unit to get them back in.

As a general rule, most "flex" style cables have gates on the companion connectors that must be raised to release the cable. Failure to do that will result in torn-up cables. The "gate" is usually a small plastic "cap", that is usually a contrasting color, on one side of the cable entry point that can be lifted at each end to free the cable. On re-insertion, you want to push the "gate" back down to capture the cable and move the contacts into position.

Hello,

Removing the PA board or analog board requires removing the two ribbon cables at the rear.
After sitting there for ten years they won't like to be pulled out.
Easy to destroy them. Parts of the solder coated contact strips come off, and then later when re-inserting them, they fail completely.


Before re-inserting the cables put some contact oil on the ends.
I used non-oxidizing weapon oil sometimes, when no contact cleaner was available.

Their prices are reasonable, and the service is perfect.
The number is the original ICOM part number.
You need two pieces of course.


I have found another source on Aliexpress, but not yet received my orders.
