I have a 7000 but plan on keeping it. If someone was wanting to just outright buy your 706, how much would you be asking for it? I am looking for a back-up rig.

ok Guys, please dont laugh me out of this group.

I am just putting this out to see if anyone is interested,

I have an Icom IC-706MkIIg thats about 3 years old, and I am the second owner of it, both in non-smoking environments, with the remote data cable and mount plate, also have a brand new TROY Console faceplate designed for the icom specifically.

heres what I would like to know:

I would like to upgrade to an IC-7000, but cant afford out outright, so is there anyone who has one and would like to trade radio plus a little money for the 7000? one that you just dont like, doesn't act the way you want, and you would like to go back to the 706?

and please, if you dont have a 7000 you have no need to comment here, Im just asking if anyone is interested.


Re: reliability reports of ic-7000

Steve W3AHL
 

It is hard to compare the reliability of the 7000 to other models based upon individuals' experience and forum postings. Many radio failures are caused by poor installation practices and operator error and of course some are caused by random component failures and marginal design.

I have a 7K purchased in late 2006 and another one received last month. I am happy with both, although my next radio will be an Elecraft K3!

The original radio was returned for warranty repair in 2007 and some factory updates were installed, primarily to improve grounding in some areas by adding flexible grounding fingers.

My latest 7K has some of those changes installed and some not. I assume further testing showed they were unneccessary. There have been minor changes in a couple of boards, otherwise they are identical. The firmware is not field upgradable and both of my units have the same revisions.

The most frequent complaints about the 7K are it tends to run warm. I don't see this as a problem in most applications, but I did modify mine to have the fan always running at low speed recently.

There have also been many reports of driver or pre-driver failures. I have not seen any hint of what actual percentage of units sold have experienced this problem. I have taken temperature measurements and looked at signals in these areas on my two units and don't see a problem.

A used radio is only as good as its previous owner took care of it. A new radio has a factory warranty which can be worth several hundred dollars if there is a failure. If you know the owner of a pre-owned 7K and feel comfortable with how that person treated it it should be fine. In the USA I know many owners have returned their out-of-warranty 7K to an Icom service center and had factory updates installed at no charge, which would be worth considering if you buy an older model and don't know its service history.

Re: [IC-7000] Its Back

Lee de Vries
 

Hi John,
Regarding plugging/un-plugging things while they are on, it really depends
what circuits are being switched. You can safely plug the headset because
the temporary short circuit conditions that the plug creates as it transits
past the ring and opens the tip does not cause a proble especially as the
headset is not connected to anything else. Not so the CI-V connector which
has some transistors connected to the tip/ring and during the transition DC
conditions are not normal. Furthermore the other end of the CI-V cable is
connected to a PC and it may be at a different ground potential.
If the CI-V must be hot plugged , I would disconnect the cable from
RS232/USB on the PC first, connect the CI-V and then re-connect the
RS232/USB.
You can be over paranoiac/OCD about this though.

Re: [IC-7000] Its Back

I have a new 7k so am still learning about it.
ok so it seems to be a good rule to always switch off before unplugging or plugging in anything...

Do I need to do this even if I'm only plugging in my headset to the little jack plug socket on the side?

kind regards John .... G8HUY

Re: [IC-7000] PTT Switch Failure

DeoxIT is definitely the way to fix this problem (assuming a cold solder joint isn't the root cause). I usually spray anything that hiccups with it, but I guess I was just looking for more work today.... I sprayed the switch, cycled it a few times, sprayed it again to flush out any gunk and then inspected the dome. Most of the tarnish is gone and where it was rubbing on the contact and plastic case it was nice and shiny again and worked 100% of time.

Guitar Center carries a good selection of DeoxIT products also.

Subject: Re: [IC-7000] PTT Switch Failure


I took the defective switch apart and inspected it under a microscope to see why
it failed. The switch has a snap action metal membrane that is slightly dome
shaped. There are three contacts inside -- one lead connects to the top &
bottom contacts which the circumference of the dome rests on. The other lead
goes to the center contact which the center of the dome touches when the button
is pushed. There are raised bumps on all three, which are intended to provide
the point of contact and some wiping action between the surfaces.

There is clear evidence of wiping on the center contact and the dome. However,
the bumps on the top & bottom contacts are set in too much and don't seem to
touch the dome and there is no evidence of wiping action. The edges of the dome
that line up with the contacts are heavily tarnished or discolored for some
reason. This could result from elevated temperatures during soldering being
transferred to the dome. The contacts were bright and clean. The leads are
sealed adequately where they enter the body and there was no evidence of flux
flowing along them inside the case.

Alps specifies that for manual soldering the temperature should not exceed 350C
(662F) for 3 seconds. This is probably why we see so many cold solder joint
problems on the PTT switch.

If you retouch the through-hole solder joints or replace the PTT switch in the
mic, I would pay heed to this. My iron is 700 F and I probably exceeded 3
seconds when I reflowed the joint because the solder wouldn't wick up the
plated-through hole to form a good fillet on the top side. Or the
discoloration could have happened when I removed the switch with a solder
sucker.

Also, the switch is not sealed, so you should not clean flux residue with flux
remover or alcohol unless you are very careful. The factory's flux was still on
the board, as was mine. Just use a known "no clean" flux solder.

Hmmm... My mic PTT switch has been getting flaky lately.

It occasionally fails to make contact. It clicks, but nothing happens.
Just last week I thought I was talking to someone, then realized that
the radio wasn't transmitting. It doesn't happen often, but it sure
is annoying when it does.

Looks like I might be ordering a new switch too.

Re: [IC-7000] PTT Switch Failure

The original Alps P/N was SKHHLP014A, per the Icom service manual. This part has been obsoleted according to Icom, but they didn't know the new Alps P/N they are shipping as a replacement.

Mouser normally stocks the SKHHLP010 switch which measures close enough to the part I removed, so it should work. I couldn't find a record of the exact Alps P/N I ordered about two years ago for a repair. This part is out of stock with about 1900 on order, due in late November. I couldn't find another retail distributor for Alps switches. I ordered 10 just to have on hand.

The different suffix in the P/N indicates the button length and diameter. Otherwise all the SKHHLP series is identical.
