Thanks Alan.  I figured it would be something of that nature.  I also 
figured a PL259 wasn't going to take too much power.  I personally don't 
think the U S, just like other countries, should have 1500 for a limit.  If 
a guy has a clean signal and is 60 over nine, I just move a little further 
away from him, haha.  I think 3 to 5 KW would be a better standard.  The 
bands are bigger now and most radios have band width settings so unless they 
are just plain stupid, no hams like that of course, they aren't going to run 
very wide with those higher power settings.  I never had an amp that would 
run more than 1200 out and until I got that amp, I ran 700 for 10 years 
without any RFI or TVI complaints from neighbors.  As soon as I got my SB220 
running, I had a neighbor who came from two doors down and complained I was 
getting into his TV.  I had a 2 element 40 meter beam at 70 then, too.  I 
asked him what time of the day.  He said 10:30 in the morning.  I never 
operated at that time and told him so.  He claimed he could understand me so 
that's how he knew it was me.  I explained to him about side band and CW 
and the way they sounded but he never understood, nor was he ever employed, 
but he was either drunk, or high, most of the time, so I just gave him a 
copy of the FCC booklet the told non hams how to solve interference problems 
and he never bothered me again.  Oh, by the way.  I asked him what he was 
watching and what channel because I was going to see if that program was on 
at that time once he left my front door.  He was watching a cartoon channel. 
I discovered his favorite cartoon was not on at 10:30 as well because he 
admitted he loved watching a certain cartoon on TV when his kids were in 
school.
