      50-54 mhz is Amateur exclusive in the Americas(Region 2), but elsewhere
the band is in transition from TV broadcasting. In Europe the
segment 50.0-50.5 is being used by hams on a non-interference basis.

     4 meters - As TV BC is phased out of VHF in Europe, it is my
     understanding that hams in parts of Region 1 get to use 70.0-70.5
     on a non-interference basis. I wish we could too.

      Many parts of the world (Regions 1 & 3) allow 144.0-146.0 only.
      England uses 146-148 for police, so I'm told.

>   220 MHz - Amateur use is shared with government radar.
      Only allocated to Amateurs in Region 2
U.S.A. permits 222.0-225.0 exclusively. ( Here insert wailing
and gnashing of teeth over this corrupt act.)

>   440 MHz - Amateur use is secondary to government radar.
     Most of the world: 430-440, U.S.A. has 420-450 with
restrictions. Yes, we are secondary from here to daylight.

>   900 MHz - Amateur use is secondary to government radar.
    Only allocated to hams in U.S.A. 902-928mhz. This is
    where the new cordless phones and TV 'rabbit' transmitters
    live. Also ISM stuff is here as well as a vehicle tracking
    system. Not likely to see any BC'ing here, as it is too
    junked up for good reception.

   And don't forget:
1240-1300 mhz in U.S.A. I think it's 1230-1338 in the U.K.
and Europe(?). We used to have 1215-1300 in the U.S.A. BC'ing
could try for this one.

2300-2450 mhz U.S.A. has 2300-2310, and 2390-2450 rest of
world varies. Watch out for direct satellite BC'ing to try
to grab this one! U.S.A. used to have 2300-2450.

3300-3500 U.S.A. amateurs only as far as I know.

5650-5925 U.S.A. but other countries have variations.

10,000-10,500 Worldwide allocation to Amateurs as Secondary.

Likewise from myself, have fun and do try 222 mhz 'and down'.
