Greetings software gurus,

I would like to have an antenna analyzer but am too cheap at this time to
buy one like the Rigexpert ones or the Youkit one. I was wondering if it
is possible to homebrew one using the Arduino or Beaglebone type
microcomputers. I see where they can detect SWR but I would like a sweep
function that would graph an entire band. I really haven't played with
programming since I was in junior high in the 60's using a dumb terminal
hooked up to Stanford's mainframe learning a bit of Basic. I understand
it has advanced a bit since then.
Anyone make something usable? Cheaply?

QST, I need some operators on Wednesday to QRV...

GB Hoyt
 

If you missed it last night, I've updated my post with operating times and frequencies.
http://skattagun.blogspot.com/2013/11/qst-qst-qst-great-american-teach-in.html
remember,
I'll be starting at 9:00 AM EST, see the blog for operating rules.

ALSO:
At about 9am local here today, I will QRV to test things out in the back yard here.
any help is appreciated.

BIG THANK YOU TO EVERYONE WHO HAS RESPONDED SO FAR.
I don't know about you, but I'm excited to see how things will shake down! :D

PS,
don't forget to talk this up on twitter, facebook, roundtables, whatever other trivial pursuit you may engage in that will get other hams involved.
Also,
tomorrow, I'm going to be testing some of my setup, about the same time, 9AM EST, and on the same frequencies. if you want to stop by and say hello, please feel free!

**********************************************************************

UPDATE:

TIME: 1400 UTC 20 November 2013 - 1600 UTC 20 November 2013

This is aproximate.

at 9AM Eastern Standard Time, I will begin speaking to the Kindergardeners. I'm not going to spend more than 10-15 minutes actually talking about radio, and the rest of the time I will be doing radio. I'll be on air about 9:10- 9:15 EST (local time) (1410-1415 UTC).

At about 9:45-9:50 local time or so, I will have to QRT to book it over to the other class and get set up. At 10, I'm going to run through my talk again, and should be on air again by 10:10 to 10:15. We will work as many stations as possible.

Frequencies:

15m 21.330 USB +- Depending on QRM.

20m 14.330 USB +- Depending on QRM.

I tried searching for nets, and it doesn't look like we'll be interfering on any frequencies with any of the nets, but you never know, so be prepared to move a lil, remember, SEMPER GUMBY.

I will announce via twitter: http://twitter.com/KG4GVL exactly when I QRV and QSY

RULES:

1. Let's have fun. Our point with this exercise is to ignite that little spark of curiosity we all had at one point in time when it came to radio.

2. Let's make noise, especially when we call for stations. When we get on the air, I will ask, "Is this frequency in use?" there should be silence. Then I will say, "This is Kilo Golf Four Golf Victor Lima operating Portable from Carleton Palmore Elementary School, are there any radio amateurs who wish to talk to Ms Keller's Kindergarden Class?" BAM, everyone calls at once, Let's wow the kiddos! Then we'll orderly work through the stations we have.

3. Let's be courteous to each other. After the intial noise, I will call for DX first and work no more than 5 stations, then I will call for stateside contacts via area. There's been openings this time of day to the northeast, so I will call 1's, 2's and 3's first if there's a bunch. We will give each other RS reports, our name, and then the answer to a question that the kids will determine during the opening session.

4. Let's take turns. I'll be working from two class rooms, the first session with Kindergardeners, the second with third graders, If there's a lot of people waiting on the air, and you get a chance to work the Kindergardeners, please stand by during the third grader's session. Remember, we'll need everybody's voice at first, we really want to wow them with volume on the intial call, but when we begin working stations I'll ask precendence be given to stations who did not get a chance to work the first class.

QST, I need some operators on Wednesday to QRV...

...the Great American Teach in!
Speaking about ham radio at my kids' school and I want to give a live
demonstration of ham radio.

http://skattagun.blogspot.com/2013/11/qst-qst-qst-great-american-teach-in.html

for details.
also, follow @KG4GVL on twitter, and make suggestions for frequencies
(times are being determined by teachers, and I will have that info later
today/tomorrow) using hashtag #HAMitup

I'll be showcasing some of my home-built radios, including my Rockmite,
NoGA twin tube 80, The Killer Watt radio.
I won't be very QRP for the contact aspect of it, but if time allows, I
will break out the SW-20 for some CW contacts.
otherwise, will be using SSB on the Swan.
Also featuring a shootout between two home built antennas! the 20m EFHW
and one other to be announced ...

Ge Paul, Phil and the group. 
Kinda quiet here too, but busy!
I just had a 40 m visit with Terry on 7.122, always fun. 
Been going over the pile of parts for the cyclone, getting ready to start sacking them up.
I am going to find time to Build the receiver that Dave sent us in a week or two. 
That should be a fun build for the Build A thin at Ozarkcon.
I think I may have enough stuff left from the Paraset?

SSS Sprint Results

Walter - K5EST
 

Second Sunday Sprint of Nov 10th, 2013

It was a light Sprint participation, but still 
fun to be enjoyed!

Paul    N0NBD    3 contacts

Terry   WA0ITP   3 contacts

Dave    W0CH     4 contacts

Propagation is still a bit crazy. Getting on the air
at 7PM thru 9PM seems to be a transition time
between bands.

Thanks to all for taking the time to "Sprint" !

and remember.. it is a YOUR speed net... so check in and use the speed that you 
want to talk with... I'll do my best to match you.
