Wouxen Programming Cable
by Nick Shearer 15 Oct '20

15 Oct '20

Good Evening everyone, I am a new member of the club, and also just received my Technician class license! I am studying to take my general in the next month or two here. I was checking to see if anyone has a programming cord I could possibly borrow to program my base radio that’s in my truck. I have the RL software but I seemed to have misplaced my cable and it’s a few weeks out it looks like even through Amazon. It looks like this. Thank you so much and I look forward to getting more involved and hoping to learn quite a bit from the group as I know there is so much to learn. - KN6LIS, Nick (downtown SB area)

FCC Proposal for Amateur Application Fees
by Levi C. Maaia, K6LCM 26 Sep '20

26 Sep '20

Fellow SBARC Members: Some of you may have seen information about an FCC Notice of Proposed Rulemaking which proposes to impose a $50 application fee for all transactions with the FCC Universal Licensing System. This would mean implementing a $50 fee to apply for and renew an amateur radio license. This will have a very serious chilling effect on our hobby and service if implemented. While $5/year may not seem like much for a 10-year license term, having to pay $50 (+ $15 for ARRL VE testing), could mean far fewer interest from new hams, especially younger prospects, and an inability for existing hams with fixed and low incomes to afford renewals. I hope you will take a few moments to leave public comments on the FCC. Click the link below and then click the + Express link in the left sidebar to pre-fill the form with the correct docket number. https://www.fcc.gov/ecfs/search/filings?proceedings_name=20-270&sort=date_d… The FCC does listen to public comments. Taking a few moments now could mean the difference between preserving amateur radio well into the future or seeing its elimination in the near term. Levi C.

Sig Wathne, W6LGK, passed Monday evening. We will celebrate his life after Covid19 @ the Elks Lodge
by Marvin Johnston 14 Sep '20

14 Sep '20

I've known Sig since the time he was working for Brown Medical back circa 1980 where I was also making some of their circuit boards. I also made some of the circuit boards used in his reflow machines when he moved out to the airport. He has always been one of my favorite people since he embodied (to me) how a gentleman always acted. His stories about his time in Norway in WWII times were always fun to listen to (they are also related in his book.) My favorite was when the Germans were coming house to house searching for radios. He took the radio and "stored" it in the latrine. For some reason, the Germans never checked that thus saving his and his families lives. Sig gave a most entertaining talk at a SBARC meeting some years ago where he told about his ham radio times (among other things.) I was happy to hear that Kale (his son) took over running Sakama when Sig retired a few years ago. Sig, you will be missed!!! Marvin, KE6HTS

Ulefone Armor 3WT
by Ken Alker 10 Aug '20

10 Aug '20

I heard someone using below phone on the Papa system yesterday; its an Android with 440MHz radio! The Amazon link claims it can w/stand immersion in 2 meters of water for 2 hours and 1 meter of concrete for 24 hours! (I wonder how they got it out of the concrete after the concrete set up?). Also states they tested it by driving nails with the screen (doesn't say if it passed or not)! I guess you can claim anything when selling on Amazon from China. <https://smile.amazon.com/Ulefone-Armor-3WT-Waterproof-Smartphone/dp/B07X352…>

NZ to trial world-first commercial long-range, wireless power transmission

NZ to trial world-first commercial long-range, wireless power transmission By Loz Blain August 03, 2020 https://newatlas.com/energy/long-range-wireless-power-transmission-new-zeal… https://newatlas.com/energy/wireless-power-transmission-emrod-interview A New Zealand-based startup has developed a method of safely and wirelessly transmitting electric power across long distances without the use of copper wire, and is working on implementing it with the country's second-largest power distributor. The dream of wireless power transmission is far from new; everyone's favorite electrical genius Nikola Tesla once proved he could power light bulbs from more than two miles away with a 140-foot Tesla coil in the 1890s never mind that in doing so he burned out the dynamo at the local powerplant and plunged the entire town of Colorado Springs into blackout. Tesla's dream was to place enormous towers all over the world that could transmit power wirelessly to any point on the globe, powering homes, businesses, industries and even giant electric ships on the ocean. Investor J.P. Morgan famously killed the idea with a single question: "where can I put the meter?" It has taken 120 years, but New Zealand company Emrod appears to have finally convinced a major power distributor to have a crack at going wireless in a commercial capacity. Powerco, the second-biggest distributor in New Zealand, is investing in Emrod, whose technology appears to be able to shift large amounts of electricity much more efficiently, between any two points that can be joined with line-of-sight relays. "Were interested to see whether Emrods technology can complement the established ways we deliver power," said Powercos Network Transformation Manager Nicolas Vessiot. "We envisage using this to deliver electricity in remote places, or across areas with challenging terrain. Theres also potential to use it to keep the lights on for our customers when were doing maintenance on our existing infrastructure." Emrod currently has a working prototype of its device, but will build another for Powerco, with plans to deliver by October, then spend several months in lab testing before moving to a field trial. The prototype device will be capable of delivering "only a few kilowatts" of power, but can easily be scaled up. "We can use the exact same technology to transmit 100 times more power over much longer distances," said Emrod founder and serial entrepreneur Greg Kushnir. "Wireless systems using Emrod technology can transmit any amount of power current wired solutions transmit." The system uses a transmitting antenna, a series of relays and a receiving rectenna (a rectifying antenna capable of converting microwave energy into electricity). Each of these components appear in these images to simply look like big ol' squares on poles. Its beams use the non-ionizing Industrial, Scientific and Medical band of the radio spectrum, including frequencies commonly used in Wi-Fi and Bluetooth. Unlike Tesla's globally-accessible free power dream, the power here is beamed directly between specific points, with no radiation around the beam, and a "low power laser safety curtain" immediately shuts down power transmission before any object, like a bird, drone, power thief or helicopter, can touch the main beam. There will be no difficulties this time working out where to place the meter. Emrod says it works in any atmospheric conditions, including rain, fog and dust, and the distance of transmission is limited only by line of sight between each relay, giving it the potential to transmit power thousands of kilometers, at a fraction of the infrastructure costs, maintenance costs and environmental impact a wired solution imposes. Indeed, Emrod sees wireless transmission as a key enabling technology for renewable power, which is often generated far from where it's needed. This kind of system could be terrific for getting the products of offshore and remote renewable energy generation into the city grids without the need for giant storage batteries and the like. Crude render of a temporary power transmission truck Crude render of a temporary power transmission truckEmrod It'll also be handy in certain unplanned outage events; a truck can be fitted out with a rectenna, and then driven anywhere in visual range of a relay to create a temporary wireless power connection. The company has been liaising with the Radio Spectrum Management authorities in New Zealand throughout its development process, with a view to meeting every safety standard even once the technology scales right up to high power levels, a process Kushnir says has also helped Emrod develop guidelines for the companies that will be using the technology. We've contacted Emrod to ask more about efficiency, the size, shape and state of the current prototype, future plans and what indeed would happen if you stuck your hand in the middle of the beam, and will bring you more information when we can. Update: we have now spoken with Emrod founder Greg Kushnir, who had plenty to share in our interview story. https://emrod.energy/press-release-nz-start-up-launches-world-first-long-ra…
