The PAPA System is pleased to announce that it was recently awarded a grant from Amateur Radio
Digital Communications in the amount of $157,425. This grant will fund mission critical system
upgrades for sustained off-grid operations, a self-reliant digital microwave backbone and radio
frequency maintenance tools to address the specific radio frequency requirements of the analog and
Amateur Radio Digital Communications (ARDC) is a private foundation that exists to support amateur
radio and digital communication science and technology. ARDC makes grants that support amateur
radio, funds scholarships and worthy educational programs, and financially supports technically
innovative amateur radio and digital communications projects. You can learn more about ARDC on
their website at www.ampr.org.
PAPA will use the grant funds to provide battery backup systems for three sites where Public Safety
Power Shutoff (PSPS) activations frequently interrupt service to the membership. We will build-out our
microwave backbone network to improve reliability across the linked system and add satellite based
Internet connectivity for a more robust network. In order to test, optimize and maintain the analog and
digital repeaters, filters and antennas in the system, new RF test equipment will be purchased.
PAPA is grateful for the support provided by ARDC to help serve our members and the amateur radio
community in Southern California.
