Frequency ranges are as follows

TM 11-5895-1412-12&P Frequency ranges are as follows: LF 0.0001-1.9999 Mhz 2.0000-29.9999 MHz VF-FM 30.000-87.975 MHz VHF-AM 108.000-149.999 MHz UHF 225.000-399.999 MHz EXTRA 0.0001-9999.99 MHz (includes those frequencies not in other ranges) Frequencies less than 30 MHz are rounded to point. Frequencies equal to or greater than 30 MHz after the decimal point. the fourth digit after the decimal are rounded to the third digit Rounding up occurs for values of six or greater in the extra digit. IF A NET IS NOT ASSIGNED ANY FREQUENCY INFORMATION, IT IS ASSUMED THAT NO FREQUENCY IS NEEDED. Enter into the NET TYPE column the net type. The types include PRI (primary), ALT (alternate) and RTS (retransmission). The default type is PRI. The function key selections change when the cursor is placed in this coiumn.^- To select a net type use the following function keys: (f1) PRIMARY NET (f2 (f3 (f4 (f5 (f6 (f7 (f8 ALTERNATE NET RETRANS NET #1 RETRANS NET #2 RETRANS NET #3 RETRANS NET #4 RETRANS NET #5 RETRANS NET #6 A PRIMARY NET is used under normal mode operating conditions. An ALTERNATE NET is used when the PRIMARY net communications cannot be maintained due to jamming or interference. A RETRANS NET is assigned to a retrans (radio relay) operation. If anything other than PRI is used as a net type, a corresponding net must be given. There is a 10 MHz separation between a RETRANS net and its corresponding net as well as the alternate net. The CORRESPONDING NET item is used only if the net is an ALTERNATE or RETRANS net type. The net number used refers to the DESC ID of the PRImary net to which it corresponds. Enter into the RESTRICTIONS column the frequency restrictions that have been placed on the net. Up to eight restrictions may be applied to a given net. The restrictions are entered using the letters in the range A-P. Each letter identifies the explanation of how the frequency is to be restricted. For example, “A” may indicate the frequency cannot be used in a given geographical area. Do not use commas between restrictions. Nets that have a fixed frequency requirement should not receive any restrictions. 2-27
