If two people owned it and it never made it out of the box, they must not have been hams'.
My radios have already been sent back to the factory 3 times because they wore out and quit working, from extended transmit.
If you are a real ham, you will find a way to mount a muffin fan to the heat sink and connect it in such a way that it only comes on when the heat sink gets hot!
Amateur radio equipment has a duty cycle, unlike a CB radio where you can sit and talk for hours, a FM radio needs a rest between transmissions. Most Yaesu transceivers has a 3 /7 transmit time.
This means that out of 10 minutes, you can transmit about 3 minutes.
So the rag chew where one guy talks 15 - 30 seconds, and then you talk 15 - 30 seconds, after your 6th go around, you are out of time. It limits your conversations to less than 6 minutes in 15.
Good if you are a part of a round table where your turn only comes once every 4 or 5 minutes, but not good when you are only talking to one person for an extended period of time.
My FT 8900R transceivers lays down and quits after about 10 minutes of rag chew.
Always has, always will.
You can transmit on an ICOM until the fuse blows or the car battery goes dead.
My recommendation is to buy a Kenwood.
I have never had a problem with my TM 271....
