We installed a new D-Star UHF repeater and controller at the South Bay site. Our previous system was a home-grown D-Star repeater that worked great for several years.  We decided to go with an official Icom stack to ensure compatibility with the D-Star network now and in the future.  Connect to the D-Star network on Bay-Net at 444.075 MHz.

We installed a new Sierra Radio Systems TeleSense site monitoring system. This system will monitor our repeater systems “vital signs” including backup battery voltage, temperature, AC power and RF power.  If there is an equipment failure, we will be automatically notified by text messaging.

New Yaesu System Fusion repeater installed at the South Bay repeater site. This repeater is operating on 444.425 and is in auto mode with a PL of 127.3.

The repeater will automatically switch its output to FM or C4FM digital mode depending on which mode is being received.  Make sure you program your radio for PL (CTCSS) decode of 127.3 so you won’t be bothered by the modem tones if a digital signal is present.

Over the years, the Bay-Net system  has grown to include 6 repeaters covering the San Francisco bay area.  It is an expensive undertaking.  To ensure continued service to the amateur community and organizations such as the American Red Cross, FEMA, and other groups, we have incorporated Bay-Net as a legal nonprofit organization.  We are now taking donations through PayPal and credit cards.  Just  click on the donate button.  Everything helps.  Thank you for your support !

Always wanted to get on 2m SSB?  Join us every Wednesday evening at 8:30 PM for the weekly Bay-Net 2m SSB net.

The net starts at 8 PM.  We take station check-ins and have a round table discussion.  Everyone is welcome to join in on the fun.  We meet at 144.230 upper sideband.  Please zero-beat (tune into) the net control station to make sure we are all on the same frequency.  Most people run vertical polarization so your normal 2m FM vertical antenna will work great.  Your weekly net control station is David, W6DTW.  See you on the air.
