W6YX trip to Mount Umunhum
Sunday, March 6th, 9am to 4pm
Leaving from Tresidder Parking Lot on Campus at 9am
Driving time from campus to summit: 1hr 30min
Optional 3.6 mile hike
We'll be going to the summit of Mt. Umunhum this Sunday, March 6th, to operate portable radios and test the antenna kit that we built over the past few weeks in our weekly antenna workshop. If conditions are good, we should be able to make contacts up to several thousand miles away.
There is a parking lot within a few hundred feet of the summit. We'll park there and find an area with trees to string up our antenna.
For those who'd like a nice hike, you can also park below at the Bald Mountain parking lot and take the Mt. Umunhum trail to meet us at the summit. The hike is about 3.6 miles long, with a 1000ft elevation rise.
We plan to meet at the Tresidder parking lot at 9am and drive to the Sierra Azul Parking Lot at Mount Umunhum. We should arrive at the summit by 11am. We'll plan to leave around 2pm, and should be back to campus by 4pm.
We will eat lunch after we get to the summit, so please bring a packed lunch and one or two bottles of water with you. There are public restrooms at the summit. Also, remember to dress warmly with multiple layers.

We'll be meeting on Saturdays from 1pm to 3pm to build a portable End Fed Half Wave (EFHW) wire antenna for the HF Amateur Radio bands. In the next month or two we'll also be planning a hiking trip to a local mountain top where we can operate battery-powered radios at high elevation and test our portable antenna performance. (More details to come.) We'll compare different antennas, and if the conditions are good we should be able to make contacts all over the world.
We'll meet at the gate on Junipero Serra across from Frenchman's road around 12:45pm and carpool up around 1pm. If you prefer to hike up, you can also use the pedestrian entrance on Junipero Serra and Stanford Ave and meet us at the shack. See the map below.

Talk Summary:
What do you get when you utilize blockchain Decentralized Finance (DeFi) and cryptocurrency to build one of the fastest-growing wireless networks?
How would you build a global IoT wireless network in a matter of years, not decades, and at a fraction of the cost of traditional mobile carriers who might spend billions to buy spectrum, build cell towers, and gain subscribers?
The answer is the Decentralized Wireless (DeWi) movement which is growing at breakneck speeds.
At the center of this movement is the Helium blockchain, which is powered by the LoRaWAN wireless protocol that has seen tremendous growth in IoT applications.
The Helium DeWi model has amassed legions of crypto mining fans, and its “hotspot miners” have been deployed worldwide.
We’ll explore the benefits of a DeWi network and the multitude of Helium IoT applications used in small business to big city projects.
