Hi Helen yes i know i have these issues too add to that when operating long overs are not possible due to these problems. they are amateur radio sets not designed to be used due to the duty cycle issues. some have used large fans to keep things cooler. this problem is getting worse climate control with in a car does help to keep things cooler or a shaded area. the case of this radio is also a heatsink so it absorbs heat as well as dissipating it. that does not help the electronics with in it.which get warm to work. to a point then when the temperature is exceeded it all shuts down. so we have to devise ways of keeping them cool.? put in larger boxes and blown with fans is just one suggestion which makes the idea of a small enclosure which it comes in a bit of a joke to be honest. ???????????????????????????????????????????????????????????

Hi Robert
?Yes I have done the factory reset, I think my next move is to work out what part of the design? would produce this result It looks like I have just figure it out.? Gee have you measured the temp inside the set when it been going a few minuets! here we have temps of 46 deg and in the car it can get up to nighty with the windows wound up Oh and I am talking about centigrade! Thank you for your help :-) Very kind regards Helen Sinnott VK3RY On Monday, 2 December 2013 2:18 PM, "cpcohen1945@..." wrote:

Helen -- You probably know more than I do, so take this FWIW -- . . . Have you done a "reset to factory defaults"? That has cured a multitude of
problems, on a multitude of rigs. . ? ? ? ? ? ? ? ?Charles VA7CPC PS -- and forgive me if you've answered the question in a previous post. ?
---In ic7000@..., wrote: Hi Robert Thank you for your reply. Yes it does seem that it can't be the dac as it provides the other modes.? I also notice that this radio has those ribbons as well, they make me shudder as I have had some trouble with those in other equipment. I have retired out of? radio a few years ago and I have not worked much with SMD. Is there in techniques or tools that may be appropriate? Of course I have used an iron on SMD boards but not on any thing that I have overly worried about the outcome ! Regards Helen VK3RY On Monday, 25 November 2013 8:23 PM, BT Yahoo!?2013 wrote:

HI Helen
?????????????? many of these problems coming to light are as a result of the lead free solder used in the construction of these modern transceivers. so a dry joint is the most likely cause of a lot of problems with the Icom Ic7000. ????????????????????????????????????????????????????????????????????????

Hi I am new to this group my name is Helen Vk3ry I have lost SSB upper and lower on my rig. I have been able to track the lack of TX down to the 1st IF? my thoughts it may be the processor, the rig is quite happy on am fm Rtty and good on ex. it implies the Dac is ok too,alc indicates very high alc although there is no alc voltage. I sure I am not the only one with this prob? ? ? ?? Any one with similar experience? KInd regards Helen VK3RY лл
