Date   
Call for Volunteers - FATRAC Gravel Grinder, Saturday, May 9

Michael - N6MRP
 

Hello All -

The Club is providing communications support to a new event!

FATRAC (Folsom Auburn Trail Riders Action Coalition) is a mountain bike organization that maintains trails and holds ride events. They are having a first-ever ride event at Foresthill Divide on Saturday, May 9, 2020. It is called Gravel Grinder, and it consists of three routes (45 mile, 60 mile, 100 mile) starting and ending in Foresthill, with rest stops (and radio stations) at Sugar Pine Reservoir, China Wall, Robinson's Flat, and Gorman Ranch. They project 100 - 150 riders.

We will operate pretty much the same way we do with the CERA enduro rides, only our locations will be less remote and there will be easier access. We will use VHF/UHF mobile radios with our own power (batteries) and antennas that can get a good signal out.

Operating times at the field stations will vary, and depend on when the riders pass through. Sugar Pine Reservoir will run 0845 - 1130, China Wall 1000 - 1400, Robinson's Flat 1100 - 1600, and Gorman Ranch 1215 - 1730, with Net Control 0800 - 1830. (These times are all tentative - closing times could be much later depending upon events.)

As the communications team, our job is to relay messages between the field stations and net control. This is especially a great opportunity for new hams to get on the air and see how a volunteer event operates!

If you're interested in volunteering or have questions, please contact me.

Secret Soviet "Woodpecker" OTH Radar #QST

Dennis - WU6X
 

For those of you that remember the "woodpecker" that used to tear up the HF bands, this short BBC video provides a short walk-around of the site and the massive antenna system. There is a short advertisement from Microsoft at the beginning ... just let it play out.

Track our Cubesat, the Phoenix! #satellites

Devon - KM6MDG
 

Greetings all!

The Phoenix Cubesat (or Phxsat), the satellite Trevor (KM6MDG) and I helped write flight software for, launched successfully on 2 November 2019 aboard the NG-12 resupply mission. You can find self-made footage here and the full stream can be found here.

On 19 February 2020 at 9:35am UTC, Phxsat was deployed from the ISS successfully! Of course, Trevor and I stayed up and watched at 2:35am MST... You can see our team's reaction video with all of the ISS feeds here.

Now I know you're all wondering: Can we track it? Yes, you can! The following is the homepage for the project: http://phxcubesat.asu.edu/

You'll notice a link to Amateur Operations, or you can just go here: http://phxcubesat.asu.edu/content/amateur-operations

There, you'll find detailed information from the hardware/software specifications of our ground station to the format of our health beacon, callsign, and more. If you are able to spot it, let us know! The information on how to do so is also on that page.

Of course, if you have any questions, let Trevor or I know!

Re: In-person classes canceled at Berkeley

Hi Everyone,

 

I thought I would give you a few tips on GoToMeeting, which is the teleconference app we will be using for the Board Meeting on Friday night.

 

First, you DO NOT need to download anything, nor do you have to sign-up for an account.

 

Open your web browser on your computer, tablet, or smartphone.  Type in the address:  GoToMeeting.com.

 

When the page opens up, look in the upper right hand corner and look for the JOIN button and click it.



The next screen will have a white box for you to enter the Meeting ID:  423 - 173 - 365

A new page will open and you will be given a choice, Select the one that says "JOIN ON THE WEB" no download required.  The fastest, easiest way to join & host meetings.



The next screen gives you TWO options to customize your experience.



Select "COMPUTER" if you have a computer, tablet, or smartphone WITH a headset, or mic AND speakers.

Select "PHONE", if your computer doesn't have any audio.  The next screen will give you a phone number to dial.  Follow the prompts.

Remember to mute yourself as a courtesy to the other participants.  Of course, if you need any help or have any questions, please feel free to call me at 916.534.8251.

I also use ZOOM for teleconferencing for inservice meetings I'm involved with about once monthly or every other month. I must say though that my log in is the phone number of my coordinator, so I would need to figure out what log in I would use.
I just downloaded Go to Meeting though, so I'll see how that works for me.

We’re just in the process of releasing this podcast now. And as soon as Apple iTunes recognizes it we’ll have a major social media platform blast, but I thought all of you would appreciate where we’re going with our new series “What Hams Do.”
 
In this first episode we juxtapose the very different reasons two young hams got into amateur radio. One’s a hacker, and the other, an 11 year old scout. Let us know what you think about it:
 
 
You can subscribe through your favorite podcast distributor (iTunes in a couple of days) and via RSS feed right to your browser.
 
Please share this, especially with your non-ham friends.

Re: W6EK 2M Repeater Failure Update

Gerry - WA6E
 

When repeaters first became popular back in the 1960s and 70s, they were all carrier access.  You still find a few of those in more remote locations.  But I'm surprised a repeater in an area like Atlanta can survive without PL.

Re: Repeaters with no PL tone [WAS: W6EK 2M Repeater Failure Update]

Indeed!  That would be a fun project.  I like the built-in anti-kerchunking and how it enforces good operator practice such as waiting at least a half second before talking. And the elegance of requiring _no_ PL tone. (Of course they have to be the one unique site with no tone...)   The tranmitter fingerprinting is intriguing, and I would really enjoy taking that further by having a group (at least three) repeaters in the area share Time Of Arrival data as well.

Yeah, it looks like there's going to be a lot more telecommuting/teleconferencing for at least a short period of time as the COVID-19 situation plays out.

Zoom is the best video conferencing software I've used.  I liked Hangouts a lot, and prefer it to Highfive and GoToMeeting, but Zoom is great for both 1:1 meetings and larger groups.  It's a lot of fun to have our whole Engineering department participating in a meeting from their desks.  It's nice to a grid of everyone's faces in real time, reacting to what's being discussed.  

I use it with remote coworkers all the time, enabling me to see their screens and talk them through things.  I can even draw on their screen or type text that appears floating on top of whatever they're doing.  Sometimes I'll just type out the line of code that I'm suggesting and they can just look at what I've typed and copy it.  (There is also the ability to send text in a chat window, so that they can easily copy/paste it.)

Zoom is even better if you have a conference room set up for it.  We have two televisions in each conference room now.  One shows the person talking (or the screen/presentation being shared) and the other television shows the rest of the participants.  The experience is controlled by an iPad on the table, which knows which conference room it is in and which meeting is scheduled for that room at that time.  It means that you can walk into the room and the app on the iPad already knows which meeting is scheduled and has a big button on it which will join the meeting with a single tap.

Repeaters with no PL tone [WAS: W6EK 2M Repeater Failure Update]

Jef - N5JEF
 

Nathan, if you think having a repeater with no PL tone is interesting, take a look at this info about the Seattle Repeater Group's system:

- Jef  N5JEF

From http://www.qsl.net/srg/index.html
Seattle Repeater Group (SRG)'s highly computerized repeater is located "High atop Green Mountain" eight miles west of Bremerton, Washington on the Kitsap Penninsula. This repeater is owned by the Seattle Repeater Group and administered by Phil, K7PF. It is allocated the frequency pair 146.28/146.88.

The SRG repeater has several unique operating characteristics of which a user must be aware. A half second of audio silence is necessary to start the repeater. A weak signal may not start it, but can answer once the system is up. Any sub-audible tone will totally prevent startup. The repeater possesses a defense against Kerchunking.

The "courtesy" beep (at the end of each transmission") tells users that the repeater is available for use, and that all timers have been reset. It is actually not a tone but a direct FM data burst at 9600 bits per second which sounds like a tone, sometimes. If you have an IBM PC (or clone), with EGA or higher graphics, you, too, can read this data burst, identify users, and tell about the characteristics of each transmission. "

http://www.qsl.net/srg/operations.htm#KERCHUNK

"Kerchunking" (keying up and immediately releasing the microphone button) the repeater momentarily may result in a CW "?" or a "Please Identify" voice message. Nothing will have been repeated.

The repeater is immediately put into AUTOVOX mode and remains there until the next even minute (every two minutes.) Further Kerchunks have no effect.

One must exceed the 2 KHz LOW DEVIATION threshold to start the repeater while it is in AUTOVOX mode. Successful starting cancels the AUTOVOX (until the next Kerchunk, of course.)
