News & Events


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.

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

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.

Bay-Net wins Editor’s Choice at Maker Faire Bay Area 2015

At this year’s Maker Faire Bay Area, Bay-Net hosted “Antennas for Nepal”, a hands-on build project to benefit the people of Nepal.  At the Maker Faire, visitors were invited to help build wire dipole antennas that will be shipped to Nepal to deploy for NVIS HF radio communications.  We helped raise awareness of the ongoing humanitarian disaster in Nepal and gave people a chance to build something that could actually be used to help out.

As a result Maker Media (organizers of the event) gave Bay-Net two “Editor’s Choice Awards” for our project.

The Bay-Net folks in charge of the project are David W6DTW, Beric K6BEZ and Mike KI6OID.  We also had help from several other people including Bernard KI6TSF, Suresh W6KTM, Sujay KK6SET, and others.


Global Nepali Professional Network (GNPN)

GNPN aka CAN-USA is an American organization dedicated to the professional development of its members and technological progress of Nepal. It is a tax-exempt 501(c)(3) non-profit organization with members throughout the United States. The organization continues to utilize the creativity and talent of its members and the broader American community to develop technology-rich solutions that address some of Nepal's challenges.

Bay-Net / CAN-USA Deliver First Repeater to Nepal

Last year we kicked off a "sister repeater system" arrangement with Tribhuvan University in Kathmandu, Nepal.  We worked with them to design "Radio Mala" the vision for a network of linked repeaters in Nepal to be in place when the next big earthquake hits.  Little did we know that the people of Nepal would experience a major quake within a year.

The plan was to build a 2m repeater and ship it over to Nepal and get it installed at the university in Kathmandu.  Eventually we would add more 2m repeaters and link them via UHF.

The repeater was assembled and tested at National Instruments in Silicon Valley.  The package was almost ready to go when the earthquake hit.  We packed it up and shipped it out.  It was briefly stuck in customs and with some political juggling we got it released to the University.  It arrived this week and will be in service in the next few days.  

Suresh and David are the movers and shakers of Radio Mala, the effort to equip Nepal with ham radio communications capability for disaster prep, education and recreation.  Bay-Net has played an important role supporting these efforts.  Listen to this great pod cast to learn more.   Click to Listen !
