Repeater Systems
The Rocky Ridge Repeater Group (RRRG) is the Technical Committee of MDARC. RRRG is charged with the operation and maintenance of the club's repeaters located on Mt. Diablo. These repeaters are open repeaters. That is, they may be used by any licensed amateur radio operators regardless of club affiliation, so long as they are operated in accord with the FCC and club rules.
W6CX and Northern California 440 Repeater Restrictions
The power output on our 70cm (440) repeater has been reduced by 50dB due to a request from the US Air Force. This change is necessary to mitigate the interference issue affecting the PAVE PAWS radar (PPR) system operating in the 70cm band. This has resulted in the following changes to our repeater system:
440 and 220 are now permanently linked.
The Morning nets that were run on 220 linked to 440 are now run on 220 linked to 2m.
EchoLink and IRLP are both now accessible only from 2m.
The Thursday evening net will be conducted on 2m linked to 220 and 440.
The ATV output has been moved from 427.25 MHz AM to 1244.50 MHz Digital.
This is an issue that affects all Northern California 440 repeaters. Read more here:
