I've had that problem with a few Kenwood radios over the years. Can't say on 
the 590, never had one and by the time I can afford another HF radio it will 
be long forgotten but I'd say most of the Kenwood radios I've had over the 
years if you touch the speaker plug the wrong way it cuts back or out but if 
left alone they're usually fine.
