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!

ICOM IC7610 : Pannes rencontrées

J'aurais du mettre le titre au pluriel...

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

Perte de réception :
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?

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
