The PA transistors and associated components are very stout. The max temperature, while important is not as important as how quickly it cools down after TX. I suspect that you have a fairly decent break during RX if your TX times are long enough to get it up to 185F that it cools off a bit. It you do not see a god temperature drop after TX, then one of the two fans may not be operating at an optimal level.
The FLEX-3000 will take a 1 hour key down at full power, but if you get much over 195F for a prolonged amount of time make sure you are taking breaks to allow for an adequate cool down cycle. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tim Lemmon Sent: Wednesday, May 12, 2010 4:07 PM To: [email protected] Subject: [Flexradio] Flex 3000 upper temperature limit? I read the numbers somewhere, but can't find them here, or in the manual. What is the upper temperature limit we should avoid on Flex 3000 rigs? I can get mine up to 185 degrees F (displayed using CTRL-SHIFT-I command) with digital transmit pretty easily. Everything seems fine, but the cooling fans are certainly spinning!
