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.
