Access to archived Warehouse data?

[JanH]

Hello Dave,

I have played back the original Audacity recording that was made when FUNcube-1 was first activated on 21 November 2013. With the latest version of the Dashboard it was possible to decode the first few frames that were received. Those were not decoded at the time. Everything has gone wrong that day, the Internet connection fell away and I could only upload the few frames that I got after the pass, manual Doppler compensation and the tuning steps on the FT-817ND were too big and to top it all an important telephone call came through just when FUNcube-1 started transmitting... Switch-on also took place when FUNcube-1 was already dipping down to the horizon. Still, I got something :-)

Back to the question: Is there any way in which archived FUNcube-1 data from the Warehouse could be obtained, either by direct access or on request? I am just very curious to see where these newly recovered frames would have fitted in among those initial ones that were uploaded by Alan, ZS1LS, and from here.

Thank you!

Hi,

I will take a look and see when they were captured and how they got interleaved.

Normally if we have seen the packet before we simply record the user against it.

If it's a new packet we mark it as out of sequence in terms of the database.

I'll look at it this evening.

Thank you very much, Dave!

(The 'new' frames that I have decoded include two from sequence 469 and two from sequence ahead of those that I have uploaded).

Oops! Should have mentioned that I have not attempted uploading the 'new' frames... (According to the Warehouse rules these would be rejected in any case).

Hello Jan,

Do you have the frame numbers?
This will be 0 to 23 for the sequence.

Thanks

Hi Jan,

I can confirm all those frames are also in our database.
470/4 was already attributed to you!
Unfortunately no exciting new frames for us, but nevertheless, very well done!

Hello Wouter,

Very interesting indeed!

Thank you very much for taking the trouble to provide this information.

I have played the recording again and though I can hear eight frames before frame 469/20 the tuning was just to far off to get any decoding...

Even now my reception of the low power telemetry transmissions is rather weak and it is amazing that it was possible to receive those initial 20 mW frames at all! The antenna used then and still in use now is a 2m mobile whip.
