No. Not at all. Several  reasons, among them, possible interference to PLC. 

In addition, the  USCG claims ownership of that spectrum. They have had 
plans for years to  
install high-accuracy ground-mounted GPS systems there, although they have  
never, ever, 
gotten funding for it, and the new eLoran will work better  anyway.

FYI, I have been involved in trying to "resurrect" the 600  meter band for 
at least the past 20 
years. I started the forum, 600MRG,  for 600 Meter Research Group then, and 
still support it 
now.

At one  time, we had worked very hard to get a group license to operate in 
that band,  450 to 
510 kHz, and had the license in hand after at least 2 years of  work, one 
or two of our group 
actually got on the air, and the USCG  suddenly shut the entire effort down 
as they had been 
"missed" in the  discussions which the FCC had initiated with users of that 
band.

BTW,  there were certain FCC agents who enthusiasticlly supported our 
efforts and  gave us 
very significant help to get our license. We were both very  grateful and 
somewhat surprised 
at their efforts.

After that,  within a few years, some started to apply for, and receive, 
experimental  licenses 
to operate on spot frequencies in the band.

Then Dr. Fred  Rabb (I forget his call) managed, after at least 3 years of 
work, to get a  
"group" experimental license to operate over a very small range of  
frequencies in the band. 
He had to have help from the ARRL to finally get  action out of the FCC.

Then things built from there.

So, from my  perspective, it has taken at least 20 years to get to where we 
are  now.

In addition, of course, there is the group, most of whom are hams,  who put 
KPH back on the 
air. It turns out that many of the original  coastal 600 meter stations, 
and even some ships, 
had valid licenses for  operation in that band which had never expired, and 
which the FCC 
will  still renew today. In fact, I know of at least one case where someone 
in the  midwest 
applied for and received a NEW license for such a  station.
