Robert,

It's probably mostly in the antenna, although some receivers do seem to 
be able to filter out more of the hisss than others.  But, if there's 
too much background noise, you probably couldn't hit that repeater 
anyway, at least not with a very good signal.

I find the quality of sound from the thf-6 is a bit shart and really 
does seem to make the background noise more noticable.

For example, if you get something like one of the kenwood mobile rigs 
with a larger internal speaker, you may find the background noise 
appears to be less even though it may be actually pretty close to the 
same.  It can sound different due to the frequency response in the 
receiver and speaker.  I find the speaker on the thf-6 often hard to 
understand even without backtround noise.
