2007-06-25  First time alarm at high resolution.

1423948091Hz

2007-06-25T07-49-19.WAV 8 Meg WAV

Notes:

  1. This signal tripped the alarm at the highest resolution (1.4 Hz/Bin).  This is the first time a signal has managed this feat
  2. The JPG (above) shows a partial view of the signal only but does show the section that caused the alarm
  3. As I watched it the signal started to move up band on the screen.  Since I still had chirp running this means that the signal stopped moving in step with the earth Doppler.
  4. The WAV file is small because I stopped recording manually when the signal stopped its Doppler.
  5. Through several more complete JPG generations it failed to trip the alarm again.
  6. I will re-visit this location again but for now I will reserve a decision on this signal

Notes:

  1. Although I can see the signal quite clearly in the saved JPG and WAV data it
    seems to have gone away.  I'll keep monitoring for a while.
  2. Since I have saved the WAV data I can play it back into my system and put
    the FFT at its highest resolution and look for Doppler...
  3. Playing back the saved WAV files at the highest FFT does show Doppler on the
    signal.  Unfortunately I had the record timer set for 1 minute so the files
    are small (5 Meg) and only show a portion of the frequency shift.
  4. This signal does deserve a monitoring session
  5. The signal came back on a few minutes later and a close up monitoring was possible.  It is located in Agr (Not HIP 1499) and it has a positive frequency movement.  It is *Busted*

Notes:

  1. This signal tripped the alarm at 20%
  2. Upon increasing the resolution to 1.3 Hz/bin (as in the JPG above) the signal no longer trips the alarm
  3. Close examination shows that the signal is drifting up band rather then down.

Notes:

  1. Very loud signal

  3. Not local interference

Notes:

  1. The WAV and JPG are tagged with SML data.  You need the SETI Net File Manager to decode it.
  2. Signal does not seem to have Doppler but is sensitive to antenna movement (its in the sky not on the ground).
  3. Needs to be revisited

2007-04-20T07-36-38.WAV 8.3 Meg file

1,422,960,100 Hz, DEC -8.51, Ra 0.25

Notes:

  1. To see this signal you must slide it to the right
  2. This signal tripped my alarm when the Spec Ana was set to 10.7 Hz/bin.  When I moved to 2.6 Hz/bin it no longer tripped the alarm.  Close examination of the signal shows that the signal does not have Doppler but does drift around.  At the lower resolution it did stay within the 10.7 Hz bin long enough to generate a hit.  At the higher resolution it did not.
  3. Chirping was running and the bins did shift by six during the higher resolution collection.
  4. This signal does show something that I have seen a couple of times now.  In the middle of collection the signal suddenly did a frequency shift of about 50 Hz.  This shift is enough that my alarm will not go off.  Would it not be unfortunate that ET is indeed running a beacon but is also FSKing very slowly for data transmission and because of that shift my alarm does not detect it!!!

2007-04-19 Tracking signal.

Notes:

  1. This signal was first noted up band then tuned down.
  2. It does seem to have Doppler on it
  3. The first JPG shows a black line I use to calculate any Doppler shift
  4. Signal faded out at about 11:15 AM pacific
  5. Reported on Argus HITs list
  6. Signal deserves to be looked for again

This signal did not show Doppler.  Notice the black ID line added by myself for testing

2007-04-07 Stopped at 1379,269,900 Hz


2007-04-07 Stared at 1378,959,400 Hz for about an hour with no return.  Now moving up band.


2007-04-06 Start at 1376,455,000 Hz - End 1378,970,000 Hz

Notes:

  1. Signal came and went at 1378,959,400 Hz
  2. Did not generate a JPG for some reason (Software bug?) and no WAV.
  3. Monitored for several minutes with no repeat. 
  4. I was integrating heavily and had the Spec Size cranked up to 16K.  I was also Chirping so it must have had Doppler.
  5. Review the location again tomorrow.

WAV File 25 Meg

Reported as a Hit:

DEC; 02.72
RA: 00.76
FREQ: 1,376,387,000
Staggering around by about 4 bins (2.6 Hz/bin)
In band (BPF in/out test do not change the amplitude)
Point in sky  - when moving antenna signal goes in and out. 
I will post a JPG of this signal in the HIP 1499 archive area.

2007-03-31

1375,351,500 Hz

Wandering signal detected and rejected.  This signal is in band (switching the BPF in/out doesn't change it) and seems to be fixed in the sky.  It does not show Doppler.

Stopped for the day at 1375,750,000 Hz
