I've been overhearing that a couple of the local amateur radio club members had the Radioddity QB25 (25W quad band mobile), and many of them are suffering failures outside warranty. Anyone have this unit and suffer similar failures? Is this a radio to avoid?
It sounds like this unit was designed way too small for the power output and likely fried the output transistor. A fan based cooling system is very hard to design right and it seems like it got the better of the designers (and apparently, owners.) I'm just comparing the size of the heatsink on my IC-U400 rated for 35W, and the much smaller QB25 at 25W must be roasting in there...
Anyone have teardown pictures somewhere? Curious to see its guts.
