IRA Frequency Utilization (Band Plan) – July 23, 2006

Preface

IRA coordinates FM and ATV repeaters and auxiliary links on frequencies appropriate for the type of operation according to a set of band plans. These are based on the recommended ARRL Band Plans, but do not follow them exclusively.

Our goal is to implement band plans that satisfy the needs of repeater owners within the State of Illinois, while also protecting the interests and operation of coordinated systems in adjacent states, weak signal modes, digital (packet) communications, AM and FM simplex, and satellite uplinks and downlinks.

It should be noted, that any changes made to the bandplans only affect pending and future coordination applications. Existing, coordinated operations are considered grandfathered and shall be protected as they always have been. No existing coordinated operation is at risk due to the adoption of bandplan changes.

The sub-bands appearing in this document in bold typeface, are sub-bands in which IRA issues coordinations. Those sub-bands in normal typeface are for non-coordinated amateur radio activities.

In this document, each sub-band is identified. For FM operations, the start and end frequencies specified for the sub-band are the first and last channels available in the sub-band, not the absolute band edges. For example, although the 2m band ends at 148.000 MHz spectrally, the highest channel available on the band is 147.990 MHz, an FM repeater input. What is listed is the carrier frequency of the channel, not the spectral limits of the sub-band. For all non-channelized operations such as SSB and CW, the start and end frequencies specified are the absolute sub-band edges. AM ATV sub-bands are shown as a 6 MHz segment. AM ATV operations must use VSB filtering of the lower sideband and be NTSC compliant. The visual carrier frequency must be 1.25 MHz above the lower limit of the specified sub-band edge specified, and aural carrier frequency 4.5 MHz above the visual carrier. FM ATV operations on 23cm must use the center of the channel as the carrier frequency.

For the 438-444 MHz VSB ATV channel which uses 443.750 MHz as the aural carrier frequency, the aural channel must use a maximum of 10 kHz deviation (as opposed to the standard 25 kHz) to avoid interfering with adjacent FM operations on 443.725 and 443.775 MHz. All emissions must be at least 50 dB below carrier at the sub-band edge for any ATV operation. Proposed digital ATV operations will be reviewed on a case-by-case basis.

Spectral purity requirements for FM voice repeater and auxiliary link operations will be comparable to modern land-mobile requirements and to FCC requirements for the band in question, whichever is more stringent. The occupied bandwidth shall not exceed 15 kHz on channels spaced every 15 kHz, 16 kHz on channels spaced every 20 kHz, and 18 kHz on channels spaced every 25 kHz. Additional adjacent-channel protection is required for 2m repeaters operating on 15 kHz spacing in the 146 to 148 MHz segment due to the increased possibility of interference to adjacent channels and is considered in the coordination review of those repeater pairs.
