Let's make heading to our monthly meetings interactive!

We are implementing a new Talk-In/Travel NET before our General Meetings. At 6:45pm and until our General Meeting commences we will be taking checkins on our Sutro Tower 2m Repeater: 
145.150 Mhz DCS 664 (info here).

Bring your radios with you and lets make traveling to the meeting fun!

Tonight's Presenter - Kenneth W6KWF

2/15/2018

 
In our February general meeting, tonight, Kenneth Finnegan, W6KWF, will be presenting on "Building a Communications System from Scratch: Providing Communications Support for the Wildflower Triathlon"
The Wildflower Triathlon is one of the worlds largest triathlons in the world, and requires an extensive communications system to run smoothly every year. Despite being located at Lake San Antonio where there's only one cell phone tower and a single amateur repeater in range, the Cal Poly Amateur Radio Club and its alumni take on the challenge and deploy a communications system with half a dozen voice repeaters, an entire stand-alone APRS network, and a multi-console Computer-Aided Dispatch center.

WiresX Connect/Disconnect Instructions

2/15/2018

 
Picture
Our 2m repeater is WiresX capable. This means that you can connect it to distant repeaters, nodes or even reflectors (such as the America Link, MNWIS etc) and enjoy conversations often many thousand of miles apart. Our 2m repeater puts us on the map! 

Nevertheless this powerful feature can get in the way of running normal analogue FM NETs if not well understood. Here is what I mean; when our repeater is connected to a distant node it is connected in digital mode only. But our repeater can support both FM (analogue) and C4FM (digital) transmissions as it has been purposely set to AMS mode (automatic). Both transmissions can coexist (in serial mode). So it is very important that when we run our FM only NETs to disconnect our repeater from any distant WiresX nodes first. Equally it is important to let local digital users know that an analogue NET is about to begin. 

To make it clear, it is the responsibility of the operator who connected the repeater in the first place to disconnect it when we have a scheduled FM NET or when he/she has finished interacting with other stations or monitoring.
