Frequencies

The Oakland County Amateur Radio Public Service Corps (ARPSC) has a number of set frequencies and modes available for use within the organization.

We use multiple bands including 2 meter, 70 centimeter, and HF as needed to communicate inside and outside of Oakland County. Modes used on these frequencies include Analog FM, DMR, SSB, CW, and HF digital modes depending on the needs of the event.
