The officers of the Indiana Repeater Council propose to change our published 902 MHz band plan. The amateur radio 902 MHz band is shared with other radio users. Amateur radio users of the band have observed significant interference from these other users. Since we must share this band with others, we need to adapt our band planning to work around the interference problem.
The current IRC 902 MHz band plan calls for repeater inputs in the 906 to 909 MHz range with outputs at 918 to 921 MHz. You can view the current IRC 902 MHz band plan here:http://www.ircinc.org/?page_
Our proposed 902 MHz band plan would look like this (frequencies in MHz):
902.0000 – 902.0750 Repeater inputs (FM and digital, 12.5 kHz spacing)
902.0750 – 902.1250 CW/SSB weak signal modes
902.1250 – 903.0000 Repeater inputs (FM and digital, 12.5 kHz spacing)
903.0000 – 903.4000 CW/SSB weak signal modes
903.4000 – 909.0000 Mixed use, including links and control
909.0000 – 927.0000 Mixed broadband use, ATV, data
927.0000 – 927.0750 Repeater outputs (FM and digital, 12.5 kHz spacing)
927.0750 – 927.1250 Simplex (FM and digital)
927.1250 – 928.0000 Repeater outputs (FM and digital, 12.5 kHz spacing)
This proposed band plan loosely conforms to the ARRL band plan.
Indiana currently has two coordinated systems that don’t conform to this proposed band plan. We will work with those repeater owners to reach a compromise for their coordinations.
If you have comments about this proposal please contact myself at firstname.lastname@example.org or one of the other officers. We would like to implement this change as soon as possible.
