US frequencies around 40MHz ?

You might want to check out the "VhfSkip" email group.  People post their
loggings each day, and there are many who are also monitoring the band from
Europe.
http://groups.yahoo.com/group/vhfskip/

StrongSignals has a discussion board you might be able to find some good
information on as well:
http://www.strongsignals.net/access/boards/skip/board.cgi .  Paul Logan has
also put up a really good website with logs and utilities to help you
identify signals.  His website is: http://www.geocities.com/yogi540/

I am hearing Indiana State Police on 42.420 at the moment with references to
Indianapolis and Goshen.  North Carolina Highway Patrol is also coming in
pretty good.  They use a PL of 173.8.  For some quick CHP's plug in 39.400,
39.600, and 39.800 see if you hear references to San Diego then you know
it's the California Highway Patrol.  Those frequencies will have a PL of
162.2

US frequencies around 40MHz ?

     Go to the FCC website <www.fcc.gov> and do a search on a particular
frequency for all of the US for "PP" service code and then listen to
comms on that frequency.  Often geographical info is included in a
transmission.  Sporatic E propagation typically is 1,000-1,500 miles for
single hop.  You are receiving multi-hop with a high MUF and a
geographically wide condition.  For you to hear the California Highway
Patrol in Denmark on 42 mhz. would be extremely unusual.   California and
Missouri and North Carolina  State Police an other states are quite
active on 42 mhz.  ***ia still keeps its' 42.86 and 42.88 mhz.
frequencies, but does not use them.  I suspect you are hearing one or
more US east coast state police.  I would concentrate on those states
east of the Mississippi River that use 42 mhz.  I believe that one or
more New England also uses 42 mhz. and possibly Florida.  I know the
Florida Highway Patrol Marine operation uses 42.92 mhz. as it on occasion
in the past has been used by the Va. State Police as a surveillance
frequency.  When the skip is in from Florida, I hear them quite well
hear.

    Additionally, the Code of Federal Regulations part 47 that apply to
law enforcement operations, primarily public service assignments do
assign specific 40 mhz. frequencies for base/mobile operations to certain
states.  Do a internet search.  The CFR can be downloaded in PDF format.
I have them documented in my database but there are too many to post.  If

to you.
