Dans un autre domaine que les pannes, raie parasite générée par le ventilateur (bruit du ventilateur en fait, non perturbation électromagnétique) :
Looking at an audio analysis program fed by the rig's USB, I was surprised to see a heavy peak at 60 Hz. Since we have 50 Hz supplies and the rig is fed by DC it cannot be supply related.
It did not go away when unplugging the microphone so I now wonder if the rig electronics generates that into the audio system.

The acoustic noise generated by the fan when it comes on is also of concern that may need sorting out.
My headset mic picks it up and is quite audible in the earphones and hence transmission.

../..

Using the supplied HM219 (not directional) or my Heil proset plus.
Distance 1m or further. This 250Hz vibration seems to carry far.

../..

Generally one is not a meter away but I pick it up even there and further.
A friend has complained of the same thing. We like a quiet shack hi.
The trouble is the pitch of the noise. It is not low frequency enough.
My settings are: Mic 30%, Monitor 50%, Comp 4, TBW WIDE or MED.
That is enough to drive my 500W linear with 25W.
I have not opened the cover but suspect the fan is rigidly mounted to the frame or maybe has ball bearings.

A noter qu'il est dommage que ICOM n'ait pas opté pour un démarrage progressif du ventilateur en fonction de la température du radiateur.
Quant au bruit, la solution est sans doute d'éloigner de l'ICOM7610 les microphones trop sensibles.

Les personnes équipées d'amplificateur ne se rendront sans doute pas compte de ce problème...
lol!

Cela ne veut pas autant dire que ce poste rencontre de nombreuses pannes, seulement que je m'y intéresse...

Perte de réception :

A priori problème corrigé par la mise à jour du firmware en V1.06
I would like to ask a small favour of all who have experienced main receiver audio loss on their IC-7610.
Please e-mail me (off-list) a short description of the operating conditions and station configuration at the time of the failure, and mention what you did to restore normal operation. I shall forward this information to my Icom contacts for further analysis.

I had a few issues with my new 7610. HRO has a return policy of 10 days.
After the tone issue and no volume control. Also I think HRD with the settings might cause some issues.
I took it back to store. Bought a 7300.
I'll wait till after Dayton in the hopes they get these radio issues taken care of.
Maybe after Dayton they will also have some discounts and rebates. Hi
I know it's not all the radios having the problems, but it's not worth $4000 dollars
and all the aggravation the way it is to me..

It happens so infrequently, 3 times in 2 months, and recovery so painless why all the fretting over a minor bug that will be fixed shortly?
Tim W4YN
Symptom appears if I qsy to another band or simply after I have transmited
1. Rf on main and sub set to 12 o'clock
2. Firmware 1.04
3. Nothing but power and coax connected
4. Tried multiple resets (full) no joy
5. Turned off rig for 15 minutes
6.Turned back on all seems fine
7. Receive goes dead just listening to a QSO. repeated step 4, 5,and 6
Jim K6CEF
Well, it finally happen to me after almost a month of owning the IC-7610, I experienced a No RX failure.  Specifically, the RX went dead with no signals being heard or displayed on the spectrum scope.
It happened on 75 meters, LSB, whilst turning the VFO to my scheduled frequency.

Important observation:  As soon as I crossed 3.768.000 moving in the direction of 3.800.000, I heard a relay click, and then the RX went dead!  I would have not noticed the relay click if it were not for the fact that I had the audio turned down.

I continued to move the VFO to 3.800.000 and stopped.  The RX was still dead!

Important observation: I reversed the direction of the VFO towards 3.700.000 and as soon as I crossed back over 3.768.000 my RX came back to life immediately after hearing the relay click again.

I don't think a relay click and No RX or a relay click and RX Working again is a coincidence.  I think the relay click has a causal connection to the No Rx.

As bad as that sounds, this type of hardware problem will be easy to trace to a specific lot of relays.  I would recommend that ICOM pull a sample of 3 percent from each lot of these relays and have an independent lab perform Destructive Physical Analysis (DPA) on them.  That will become an important step to rule out Infant Mortality (relays experienced an early life failure).  Does anybody know the reliability (MCBF) on these relays?  I am just curious.

Kevin WA6JKN (Fev 2018)
Knock knock wood here, my 7610 still with original factory FW working fine in all bands all modes, no Rx sensitivity lost in any band segment so far. No tone.
I guess the sent me a good one.
You all have a good week, 73

AD4C (Fev 2018)
I had the tone again yesterday . I hit the button to mute the main receiver then un mute then it was gone and then one time when I unkeyed  I had no receive but this time I just toggled the foot switch and it was good again. No it wasnt hung in TX mode either. Strange stuff.

Dave N8DC (Fev 2018)
Similar for me although I did not write frequencies down I know I was in CW portion of 80 meters and tuning slowly upwards. I heard the click then silence.
Tim W4YN (Fev 2018)
After an uneventful period since I got the 7610 on December 9th, my rig muted (with a tone) about a week ago.  I have already sent a report to Adam (while it was happening :-).

In my case, I was on 18 MHz.  Just a single receiver, no splt, no dual watch.
I held the Tuner button to tune, and after the relays stopped chattering, the rig entered the dreaded mute audio, 500 Hz tone state.
I had the Multi Function Meter screen showing, and could tell that the rig thinks it was still transmitting at 10 watts to operate the tuner.  However, an external power meter showed nothing was going out the antenna spigot.  
(On hindsight, the rig *could* have been tranmitting; just not to the ANT 1 port... I should have checked the ANT-2 port, but didn't think of it at the time.)
The front panel was completely dead.  Every button and every knob (including the Exit button below the display) were unresponsive.
Clicking on the Multi-Funtion knob also did nothing.
I was connected to wsjt-x at the time, and the program reported it had lost CI-V connection.  
The USB CI-V and codec ports still appear on the USB Tree of Mac OS X.  I had a program written for Mac OS X (Serial Tools) which could connect to the CI-V port (i.e., Unix open call was successful), but could not get CI-V to respond to commands.
I also have an audio pass-through program that I had written for the 7610 (sends USB codec output to computer speakers), and that too could connect, but no data was coming from the 7610's codec.
After a couple of minutes, the fan finally came on at low speed.
Since the front panel was unresponsive, I had to turn off power to the rig at my power suppy (I run 15.0 volts on receive).
After letting it sit for a minute with no power, I turned the power supply back on and booted the 7610 (power button).
Everything was normal, but the fan ran at a full blast.  The Multi Function Meter did not show high temperature (to be expected, if that sensor was monitoring just the PA, and the PA was not on).
The fan finally slowed to the lower speed (there may just be two fan speeds on the 7610, irritating, and *really* irritating :-).  
The fan sat at the lower speed for a very long time.  Perhaps the FPGAs were running hot when it was in the unresponsive mode?
I don't know about causality, but in my case, the mute + tone occured right after some relays engaged/disengaged.
73 Chen, W7AY (Fev 2018)
I have had my 7610 for about a week now, and last night scared me. I had left the rig on receiving Ft8 on 20 meters while I left the shack for dinner.
On my return an hour later, I had no audio, the waterfall looked like a snow storm, like a white out. No background noise, Nada! Dead.
I immediately turned the radio off and let it sit for a half hour. I waited with baited breath.
When I turned it back on, all was okay, no problem. I don't know if this was the reported "no audio problem" or not?
I am now a bit fearful to leave the radio on for extended periods. Just a report to Adam here. Just in case.
BTW...I had updated to the latest firmware just yesterday morning.
Rich - W4RQ (Fev 2008)
This is the second time whilst turning up the band my Rx went dead.  I had just switched bands from 40 meters to 20 meters and when I reached 14.168 Mhz the RX went dead and the Specrtum Scope showed no signals.  I turned the volume way up and started tuning up the band again and came across what sounded like an "out of band signal" (Not the Tone) that was very very week as if a Oscillator Phased Lock Loop "unlocked" leaving me with a possible IF artifact.  Once I reached 14.200 Mhz I reversed my turning direction and started down frequency and when I passed 14.168 Mhz the RX and Spectrum Scope returned to life.  I could NOT hear a relay click as I had volume way up listening to static, but I suspect that a relay may have click like before as I had the Tuner on, etc.

Configuration at time of No Rx Event #2:

1. No USB disital cables connected.
2  Did not TX yet (No RF in shack)
3, LAN connected to Ethernet Bridge
4. Mode SSB
5. Blue Tooth Keyboard and Mouse
6. Bencher connected to front Elec-Key jack
7. External ICOM Speaker
8. ANT 1 only (Fan Dipole 20, 40, & 75)
9. P.AMP Off
10. ATT Off
11: IP+ Off
12 AGC MID
13 VOX off
14. Comp on Wide
15. Spectrum Scope EXPD
16. ICOM SM-50
17, Tuner On (internal)
18. Not Using any memories except for RTTY & CW messages.
19. 32GB SD Card for audio recording and setting backup.
20. My Station is both RF and Electrically grounded, LM400 coax, N and PL-259 connectors

I will provide my failure report to Adam, dealership, and ICOM in hopes that this will help solve the No Rx and/or start the replacement/refund process.

Vidéo du phénomène



Perte de ... :
I went to HRO and took the 7610 back and picked up a new one. As soon as i got it home i put in the Latest firmware.
Low and behold i have the same issues with the Decode as i did with the last two. I have pictures of what the decode scope looks like but
and not familiar on how to upload them to this group. I think with the pictures it would explain better.
As for what i had connected to the 7610 at the time of the issues with the receiver was the USB cable, DVI to HDMI to TV for a monitor.
Plus one speaker jack and that's all that was connected. I talked to tech at Icom but he's not in today so could not give him the run down
of the same issues on the new radio. Serial Number on the last radio is 12002376, this one i picked up today is 12001873 older than the last one.
If you need the pictures tell me were to upload them..
This is my third 7610.  All three had issues.

Just purchased 3 days ago. Came with 1.04 firmware so updated to 1.06. It has been working normally up until a couple hours ago.
I noticed the audio scope FFT was not displaying the received signal that was still shown on the scope side. No response to pressing
menu button. I then tried to power it off and it froze at the powering down message on screen. I had to shut the power
supply off to reset. It powered up by itself when the supply was turned on, so it did not remember that I pressed the power button.
Unit is back to normal and I've made a few contacts. Serial number range is 120022XX.
I have the RC-28 plugged in, as well as ethernet cable and rear USB2 cable, along with USB interface plugged into ACC1. All this was working and is once again.
I was toggling between TX and RX looking at the waveform from the USB interface (running FT8) mode was USB-D1. On 7.074 Mhz

Richard WB6NGC - Mai 2018
My receiver has started losing audio output on the main channel only.  When it goes silent I can move the volume control or touch the screen and it comes back for a while, but not permanently.  Have any of you had this problem, and if so did you find a solution.  I have the 1.06 software upgrade installed.  Robert, W7GKM - Mai 2018

Panne d'écran...
Le poste étant garantie deux ans (en France du moins) il est clairement préférable de laisser l' IC7610 en fonction le plus souvent possible pour s'assurer de la fiabilité de l'écran.

Have you by chance heard what ICOM plans on doing about all these Screen Washout problems?  Given that my IC-7610 serial number falls between the S/Ns of the screen failure events reported so far, it's most likely my display is defective too along with many others.

It has been suggested that maybe I should leave my radio on 24/7 to accelerate the opportunity to fail before the warranty runs out.  This is silly and I'd rather see ICOM step up and identify all the affected radios by S/N so we can schedule our returns for new displays.

Based on reading though this group's messages, it appears that this is a known problem and based on the S/N data provided so far by this group, there are a lot of potential radio's that will most likely experience a screen failure over the next many months.  

I would like to point out that the number of incident reports is Not the main issue.  It's the number of radios involved by S/N in the population from the lowest S/N to the highest S/N where a radio has experienced a screen failure.  Please see the screen failures reported below:

1) K3HTK,  2/1/2018, No S/N, Top left side washed out
2) N8DC, 2/1/2018, 12001026, Lower left side washed out
3) K6DHL 2/3/2018 12001103 See Spec Scope burn in
4) WB5JJJ,  5/13/2018, 12001105, 1/4 of the screen is fading
5) W5JMW, 5/11/2018,  No S/N,   Burn in of previous screen
6) N8DC, 5/29/2018, 12002146, Display issue again and this time the right side of the screen is washing out
7) N0JX, 6/1/2018,  No S/N, Right side Washed out
8 ) N8AWW, 6/2/2018, No S/N, Similar problem (washed out)

Interesting history that was reported to this group by W5JMW ON May 11:

No Barry, It is only some units. Icom told me the vendor assured Icom this could not happen. When Icom saw this I understand they quit using that model.  I spoke to Icom last week.  Since there is a full year warranty they suggested to hold and see if any other problems occurred.  I would do the same thing again, even after the screen issue.  You can easily see the screen.  There is a burn in of a previous screen way in the background.  I would suggest either a brand new one or a re-pack that has full warranty.  Whatever problems they will repair..73 john

Adam, please work your magic and see what can be done to ensure the best possible outcome.

vr, Kevin, wa6jkn

Plus un léger défaut qu'une panne : Bourdonnement en approchant un objet de l'écran tel qu'un stylet
The hum is heard when using a touch stylus, but not as loud.  My experimenting to identify the conditions which produce the loudest hum, I noticed the following:  Please note: Only happens on 6 meters.

    1. As I use palm of my hand and slowly approach the screen, the hum gets louder and louder.  I don't have to touch the screen for the hum to be heard.
    2.  Disconnected antenna and no change.
    3. Turned off all devices in shack, no change/
    4. Measured for common mode between equipment (AC/DC) and get zero.
    5. Toggling P.AMP from off to 1 & 2 increase the volume of the hum.
    6.  Hum is not heard when I stay away from the screen with any objects.

Power supply has a grounded plug.
   
Hope this helps!
