Re: Overheating during a contest

 

开云体育

My 7000 has always tended to run hot but I built up a pair of 12v fans with a standalone bracket to maintain a decent supply of cooling air.?
Have always used this and have never had the driver issue in the finals even with a heavy duty cycle on FT8. Rig is only used as a driver for a 23cm transverter these days so only runs less than 2watts on two metres.?

Cheers Dale Barnes VK7DG?

My IC7000 has ran hot since new, and I never really worried about it. ( on most days all day). Then I read about a fan mod where a simple mod would allow fan to run continuously.
I did the mod and it runs very cool now all day. Admittedly, I spend a lot of time receiving with very little transmitting each day.
I believe the cooler running is probably better for the radio.
There are a couple of different fan mods on the internet, so have a look at them and decide which is best for you.
Hope this helps.

This fall, I was participating in the WA QSO party (Salmon Run) on CW. The 2nd day, 4 hr before time was up, I was running (as opposed to search and pounce) on 15 and 10M. The 7000 was at full power, WinKeyer USB/N1MM, an end fed HW with SWR indicating less than 1.5. I was making a fair number of contacts when I saw my output drop and saw the temp icon showing in the red. I had been operating fast and furious since the morning - I would guess 10 hours. Ambient temps in the 70s.? No problem on day one but it was 50% CW and 50% SSB.? Since I've bought this rig in 2007, it has never had this overheating problem. I remember on this group (Yahoo group days) there was a lot of discussion about overheating 7000s but mine never did that - that is, until this contest. The next day, the rig operated just fine - nothing permanent happened.? Over the years, I've had this 7000 on two DXpeditions, many hours mobile, many hours portable with no problems. Has it become elderly and finicky about duty cycle? Like me?
?
My question is: Is there a slick way to ventilate an IC-7000 to slow the temperature rise?
?
My "nuclear option" is to sell it and buy a 100W amp for my IC-705. Sort of like selling a racehorse.?
?
Any suggestions would be appreciated.
