Because sometimes a tuner IS the answer.

Most hams don't have the real estate or the supporting structures to
install a resonant antenna with no reactance.?? Antenna tuners have been
around before most hams were born, only we used to call them Pi networks
in the old tube transmitters.

Oh but my fondest wish is that I could get the SteppIR to behave as a
resonant antenna, Norris. The SteppIR is modeled at 55 ft out in the open.
Mind is at 30 ft on top of a roof and WAYYY to close to assorted metal
objects. Could only get the SteppIR to around 2:1 SWR which would be fine
except the KPA 500 has transistors in the power out circuit and balks at
anything over 1.5:1. The SteppIR folks recommended a tuner to keep the amp
happy. And it did ... until fat fingers started bumping the tune button and
sending too many watts into the tuner.



I've heard that the tune button results in an output to a tuner of 8-10
watts. I wonder if that is true. And, if it is, I wonder if there is a way
to reduce that output so that, when the amp is in line, the output of the
amp to the tuner would be in the 8-10 watt level. That would take care of
the problem of inadvertently hitting the tune button when the amp is in line
and frying the tuner.

I think that to disable a tuner connected to the 7000, you simply need to press the tune button. That will prevent the radio from engaging the tuner. If you press and hold the tune button, that will re-engage the tuner. I use the AT-180, and that’s how it works with my 7000. Press and hold “tune" to tune, tap “tune” to turn it off. I think.

There is no tuner in a ‘7000.

And I  can show off, 335 countries, 60 years, and never owned an antenna tuner.

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.

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.

Re: [IC-7000] group migration

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

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.

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.

https://www.radioparts.com/icom-8900015210

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.
