ORCA

ORCA repeater container and antenna pole with mesh nodes mounted half way up.

Oakland Radio Communication Association

Site located in the Oakland Hills, above the CA Route 24 Caldecott tunnel and near the KPFA transmitter tower (map)(photos). This site is hosted by the Oakland Radio Communication Association (ORCA), Oakland's amateur radio club and ARES/RACES group.

ORCA hosts its WB6NDJ repeaters at this site, which includes the repeater container and a wood utility pole supporting antennas. The mesh installation includes several radios about half way up the antenna pole (mounted on a 10 ft long, 2" diameter pipe), as well as a rack in the container with switches, routers and battery backup power devices.

Nodes

ORCA Mesh Network Nodes on the antenna pole.

Location: 37.86491, -122.21995

Altitude: 1500 ft (457m)

Bearing: West, approximately 265 degrees.

Installed 2023-03-07, this dish points approximately West across the bay, towards the Wolfback Ridge site above Sausalito in Marin County, and forms part of the backbone network.

KJ6WEG-OAK-ORCA-HAP2

Radio: Mikrotik RouterBoard hAP ac2

Antenna: built-in / internal

Location: 37.86491, -122.21995

Altitude: 1475 ft (450m)

Bearing: n/a

This devices is located in the repeater container, and acts as a tunnel client, Wifi Access Point, etc.

Installed February 2023, this was an upgrade for the previous device: KJ6WEG-OAK-ORCA-HAP.

Previous Nodes:

KJ6WEG-OAK-ORCA-NSM5 - REMOVED March 2023

Radio: Ubiquiti NanoStation M5

Antenna: 15 dBi (built-in)

KJ6WEG-OAK-ORCA-SectorTi - REMOVED March 2023

Radio: Ubiquiti Rocket M5 Titanium GPS (radio disabled)

Antenna: Shielded, Adjustable Sector (Ubiquiti AM-M-V5G-Ti)

Other Devices:

Ubiquiti G3 Flex Camera

This camera is mounted on the antenna pipe, facing approximately west-southwest towards downtown Oakland.

Ubiquiti NanoSwitch

There is a NanoSwitch on the antenna pipe, which brings in the Ethernet with 24v PoE and distributes it to the Sector, PowerBeam and Camera. We plan to replace this with an EdgePoint R6 in the future.

MikroTik Wireless Wire

This small 60 GHz radio is mounted on the secondary (metal) antenna pole behind the repeater container, and points at an identical device at the FishRanch site (KPFA tower), to provide a backbone link between the sites.

Ubiquiti EdgePower 54v 72w

This device in the indoor rack is both the primary power supply and UPS & charger for the battery backup.

Ubiquiti EdgeSwitch 8 150w

This device in the indoor rack provides data connections and PoE power to the ethernet cables going out to the radios, as well as for some of the other devices in the rack.

Ubiquiti EdgeRouterX

This device in the indoor rack manages the available WAN networks (connections to the internet).

PolyCom IP Phone

This is the "ORCA-Repeater-Phone", at BAM/SFWEM WIMETS extension x6722

Site Details

Configuration

ORCA currently hosts an EdgeSwitch-8-150w, and EdgePower-54v-72w and a EdgeRouterX in the racks in the repeater container.

ORCA connects to Fish Ranch using a Mikrotik Wireless Wire RBwAPG-60ad (60GHz, 1Gbit Full Duplex)

Plans

• More ventilation work in ORCA box
• Replace NanoSwitch with EdgePoint R6
• DONE March 2023: Replace current mount (which was temporary) with a better engineered solution
• DONE March 2023: Move current nodes onto new mount
• DONE March 2023: Add a dish similar to the Fish Ranch <-> Bruno dish and point it at Wolfback
