interferometry at 35 MHz
Hi, i am busy with adding interferometry at 35 MHz.
I use 2 inverted V beams on a baseline West-East with a
140 m distance between them.
i can locate Cassiopeia A within 1 degree.
I like to change to phasing interferometry. Therefore i will
build 2 coherent receivers like the jove ones.
My problem is: i must have AD-converters, fast anough to get
3 samples per sinus at 6 KHz.
They told me, a computer sound cart will do the job.....
Can anybody help me with information... software etc.
The recording will go for about 1 second.
When i get two files with the data from my two antennas.
i like to use my own written programs's to do a lot
of calculations .....
My goal is to make a map of the sky at 35 MHz...
Anybody can help me???
Thanks
For more information about my results etc.. see my site
http://home.kpn.nl/apon001/huis.htm
Go then to the menu-item interferometry...
it is in Dutch.. but later starts Englisch.
You can see some photopgraphs and graphs.

This is my field of study for my next following semester project n I don’t familiar how I can say my thanks for much kind of assistant you did for building up my project incredibley. My name is ketty and I am trying to exploring on this topic for a trrefic documentation and got your site on top most page of ask.com .You contain a very and smooth interface along with superb content on your site .I as well manage a personal website and nowadays you are in my beloved internet site list . many thanks for the great assistant.all the best .
Okee Ketty, that is very nice.
Greetings Wim
At certain times i receive strong disturbances.
for example:
7 march 2011 14:30 to 16:00 UTC
2 april 2011 07:00 to 12:00 UTC
28 april 2011 17:30 to 19:30 UTC
7 may 2011 08:00 to 13:00 UTC
10 may 2011 18:00 to 19:00 and 21:55 to 24:00 UTC
11 may 2011 0:00 to 04:00 UTC
12 may 2011 11:05 to 12:20 UTC
14 may 2011 08:30 to 13:00 UTC and 20:10 to 20:40 UTC
15 may 2011 15:00 to 16:20 UTC
16 may 2011 8:40 to 09:00 UTC
I think , this can be Jupiter...
Can somebody confirm this??
Wim
In two cases i do hear the beach-waves type of noise.....
14-5-2011 20:20 TO 21:07 UTC
15-5-2011 02:16 TO 02:42 UTC and 15:32 UTC and 16:12 to 16:17
i can listen to the recordings because i put the data in
.wav files.
Hi Wim. I have seen your site before web. Very nice studies.We would like to try to work as an example of this.
This program can help you to observe Jupiter. Enter your own coordinates, time set, the active storms, on the noise. IO-A,-B, IO, IO-A Look at the duration of observation. Map support is available.
Best regards, 73

Hi TB2NMR
Thanks, i know the existence op that program.
Point is, i do not like to buy a commercial program.....
And it gives much to much information.
and i only have to see once that my disturbances are coming
from Jupiter.. than i am happy.
If you have the radio sky program, can you please look one time
for me to my dates and times above....
That would be great.
If you are starting measurements as i do, i would be delighted to help you.

Can you send me an e-mail with the coordinate information?
tb2nmr@tamsat.org.tr
Well, my coordinates are ( +/-) 53 degrees 16 minutes 20 seconds North and 6 degrees 50 minutes and 0 seconds East.
Wim
Hi Wim,
You can go to the NASA data archive site http://jovearchive.gsfc.nasa.gov/ to see when others recorded activity from Jupiter.
Thank you very much...That would be great,
but the link does not work....
now, 20-5-2011 the site is running... that's great!
