     For some reason, I	am  unable  to	reply  to  you	suc-
     cessfully	via  electronic	 mail,	so  I'm	posting	this
     response.

     There are thousands of users in the 45 - 60 MHz  range,
     including	an  experimental  contract  station  for SRI
     International to operate on 49.84 MHz, USA-wide.

     Businesses	and state and local  governments  have	fre-
     quencies in this range.

     You already know the 6 meter US ham band  is  50  -  54
     MHz.   Channel  2	TV  is	in  the	 54  - 60 MHz range.
     Cordless phones (see attachment) operate in this  range
     also.

     There are US govt stations	in the 46  -  60  MHz  range
     also (e.g.	US Navy	at Scott AFB).



	    The	FCC has	released 10 new	 frequency  pairs  for	cordless
	    phones.  The base /	handset	frequencies (MHz) are:

	    Ch base    handset

	     1 46.61 / 49.67
	     2 46.63 / 49.845
	     3 46.67 / 49.86
	     4 46.71 / 49.77
	     5 46.73 / 49.875
	     6 46.77 / 49.83
	     7 46.83 / 49.89
	     8 46.87 / 49.93
	     9 46.93 / 49.99
	    10 46.97 / 49.97


	    This interim ruling	will be	in effect for 5	 years.	  Future
	    allocations	 will likely be	made in	other parts of the spec-
	    trum.

	    Cobra cordless phones use these and	other frequencies:

	       Ch	 Handset    Base

	     1A	or 1	  49.83	    1.69
	     7A	or 2	  49.845    1.71
	    13A	or 3	  49.86	    1.73
	    19A	or 4	  49.875    1.75
	    25A	or 5	  49.89	    1.77


	Grove Enterprises (Brasstown NC) sells FCC records on
	microfiche. That's your best source.
