Collective listening exercise 12/4/20

Post by Tim Bucknall »

This thread is to plan for a collective listening exercise on 12th april from 0400-0800utc

The time has been chosen to give the best chance of long distance tropo and meteor scatter

Here’s a simple primer on meteor scatter

We just need to pick a piece of the band that suits the most people

I'm getting a little closer to trying this Tim. I could be set up as early as tomorrow or Wednesday. I'll catch up with you in the chat.

All set up here now and successful MS pings decoded overnight.

Are we all recording 6 MHz? What range? Bottom or top of the band? Presume beaming east and horizontal.

QSL?

Ok looks like bottom of the band wins
That’s actually best for me but I didn’t want to force it on everyone else.

For those who are limited to one channel pick any one that suits you below 92.2

Morning,
I will do it Tim. Just a question, may I log the very short pings, these with no choice to be ID? They are difficult to find with the data analyser and sometimes are dozens of them in some frequencies.

OK then. Bottom of the band it is. For me, that will be 87.5 - 93.3. I will have the antenna horizontal. Just the time to arrange now. Sunrise is best. Are we all able to use timed recordings? My suggestion would be 06:00 - 08:00 or beyond. Or are we restricting this to just one hour? Later than this is fine.

As for logging all the pings, that would be a chore. A general summary would do, but we are going to be looking for IDs more importantly, should we be lucky enough to get any.

PS The same timeframe on 22nd April would be better :D

You can log whatever you wish .

What I hope to achieve is that when we all compare files what’s weak on one person’s file will be strong on someone else’s file and we’ll be able to identify stuff we normally wouldn’t.

As for online storage for files
I’ll clear out my google cloud storage and give you all access.

Yes peter we may repeat it in 10 days ;)


Recording wise I’m going to have to leave it recording when i go to bed and just delete the hours I don’t need


our pc clocks should be synchronised as best we can
So we can match individual bursts

This project is influenced by the MW offsets group and the SETI program :D

Hi Tim,
Finally I will record from 87,8 to 92,8 MHz, now that I discovered the advantages of the Console v3 Data analyser... ;-)

Also I will use my 4el Yagi towards the East instead my vertical 1/2 dipole although this is allowing me good catches these latest days. Today I got BBC-R4 (North Hessary/Sandale) on 92,5 MHz @ 5:54:11 UTC. I will be recording from 5utc onwards (Not enough free storage...) :-E

I went into the Console Cloud and just saw "cle_april_12th_2020" with no sub-folder... What am I missing? my e-mail is jotagarzon at yahoo... My clocks are synchronised with the Mainflingen signal!

great you can see it!
i'll keep trying to make the subfolders visible, if you still can't see them on the 12th
just upload your files in a folder with your name on

good work with Mainflingen.
i hope you will get lots of nice surprises when we compare recordings!

So we are listening from 0600 UTC to 0800 UTC. Did I understand that correctly?
I hope I can get my antenna cable fixxed until then.

I am very sorry about that but unfortunately I cannot take part in the listening exercise because my antenna doesn't function very well and a cable is broken and I can't replace it right now due to the circumstances.
Just wanted to let you know.
