Abreu, Brian

Both days reception were conducted using a Yaesu FT-991 in 9kHz wide
AM. The antenna is an inverted L. The vertical portion at
approximately 25 feet up and the horizontal portion slopes down about
10 feet to the north.

I do not have audio from the 25th. The audio from the 29th is recorded
via the internal sound card of the 991 with VLC recording to 256 kbps
mp3. The full audio file begins approximately 3.5 minutes after the
transmission. Moments of audio attenuation are me applying filters to
clean up noise (well, attempts anyways).

Summary: Bad on the 25th. Very audible on the 29th. The 29th was very
early in the morning, which likely helped. This was a lot of fun to
chase.

Expand	2019-03-26	I. Prelude / II. Introductions to the Ghost / III. Methodologies in Music and Morse		Time 00:30:00 – 00:41:00 Frequency (MHZ) 3.35 Antenna inverted L Receiver Yaesu FT-991 Note Nothing discernable; loud buzzing. (Localized noise possibly?)
Expand	2019-03-26	IV. Saxophonal Stochastic Ghost Resonances		Time 00:41:30 – 00:46:30 Frequency (MHZ) 2.80 Antenna inverted L Receiver Yaesu FT-991 Note Nothing discernable; loud buzzing. (Localized noise possibly?)
Expand	2019-03-26	V. Wolves Chasing the Ghost		Time 00:47:00 – 00:52:00 Frequency (MHZ) 2.80 Antenna inverted L Receiver Yaesu FT-991 Note Nothing discernable; loud buzzing. (Localized noise possibly?)
Expand	2019-03-26	VI. The Mind and the MRI		Time 00:52:30 – 01:02:30 Frequency (MHZ) 2.80 Antenna inverted L Receiver Yaesu FT-991 Note Nothing discernable; loud buzzing. (Localized noise possibly?)
Expand	2019-03-26	VII. Letters and Numbers		Time 01:03:00 – 01:09:00 Frequency (MHZ) 8.00 Antenna inverted L Receiver Yaesu FT-991 Note Could make out groups of typically 2 to 3 letters. Each group would fade away for about 20 seconds. I could hear the low frequency of speech for a lot of the transmission but could not make out the letters/numbers. I heard more phonetic letters than numbers.
Expand	2019-03-26	VIII. Pictures and Words		Time 01:09:30 – 01:15:30 Frequency (MHZ) 8.00 Antenna inverted L Receiver Yaesu FT-991 Note 01:09:30 - 01:15:30 UTC I did not hear any SSTV. Short, faint groups of characters.
Expand	2019-03-26	IX. Spy Cameras from the Sky and a Mystery Box in the Woods		Time 01:16:00 – 01:26:00 Frequency (MHZ) 6.90 Antenna inverted L Receiver Yaesu FT-991 Note 01:16:00 - 01:26:00 UTC: 6.90 MHz This was the best response of all transmissions. I could clearly hear speech in the background. Unfortunately there was a very powerful conversation in the foreground. There were also a few digital bursts which sounded like ALE modems. Towards the end I was able to decode some SSTV sounds, which were recognized as Scottie 1. No readable image.
Expand	2019-03-26	X. Not with a Bang but with a WSPR		Time 01:26:30 – 01:29:00 Frequency (MHZ) 3.35 Antenna inverted L Receiver Yaesu FT-991 Note 01:26:30 - 01:29:00 UTC: 3.35 MHz Nothing discernable from loud buzzing. (Localized noise possibly?)
Expand	2019-03-29	I. Prelude / II. Introductions to the Ghost / III. Methodologies in Music and Morse	Audio	Time 06:00:00 – 06:11:00 Frequency (MHZ) 2.75 Antenna inverted L Receiver Yaesu FT-991
Expand	2019-03-29	IV. Saxophonal Stochastic Ghost Resonances		Time 06:11:30 – 06:16:30 Frequency (MHZ) 3.35 ; 2.75 Antenna inverted L Receiver Yaesu FT-991 Note 06:11:30 - 06:16:30 UTC: 3.35 MHz - 2.75 MHz High noise but tones audible. Remained on 2.75 MHz.
Expand	2019-03-29	V. Wolves Chasing the Ghost	Audio	Time 06:17:00 – 06:22:00 Frequency (MHZ) 2.75 Antenna inverted L Receiver Yaesu FT-991 Note 06:17:00 - 06:22:00 UTC: 2.75 MHz Still high noise but could definitely hear what sounded like distant wolf howling. Really neat. Digital filter was slightly more effective here for portions. This was my favorite to hear. I cut a portion of the audio that was best (using the FT-991 filters)
Expand	2019-03-29	VI. The Mind and the MRI		Time 06:22:30 – 06:32:30 Frequency (MHZ) 3.35 ; 2.75 Antenna inverted L Receiver Yaesu FT-991 Note 06:22:30 - 06:32:30 UTC: 3.35 MHz - 2.75 MHz Not bad on this. Would not be a credible SSTV contact based on image output but still decoded as Scottie 1. Images attached
Expand	2019-03-29	VII. Letters and Numbers		Time 06:33:00 – 06:39:00 Frequency (MHZ) 2.75 ; 3.15 Antenna inverted L Receiver Yaesu FT-991 Note 06:33:00 - 06:39:00 UTC: 2.75 MHz - 3.15 MHz Had radio at 3.15. Switched to 2.75 towards end and picked up audio. Can hear the lower notes of a female voice in the background. Some fading in towards the last counts of 90 were very readable.
Expand	2019-03-29	VIII. Pictures and Words		Time 06:39:30 – 06:45:30 Frequency (MHZ) 2.75 Antenna inverted L Receiver Yaesu FT-991 Note 06:39:30 - 06:45:30 UTC: 2.75 MHz Same as above. Fading in and out with low notes of female voice. I could pick up some portions. Oscar and Echo being the easiest to always here.
Expand	2019-03-29	IX. Spy Cameras from the Sky and a Mystery Box in the Woods		Time 06:46:00 – 06:56:00 Frequency (MHZ) 5.10 ; 6.90 Antenna inverted L Receiver Yaesu FT-991 Note 06:46:00 - 06:56:00 UTC: 5.10 MHz - 6.90 MHz Nothing here at all. I can hear the SSTV transmission towards the end but not enough to pick out any image
Expand	2019-03-29	X. Not with a Bang but with a WSPR		Time 06:56:30 – 06:59:30 Frequency (MHZ) 2.75 Antenna inverted L Receiver Yaesu FT-991 Note 06:56:30 - 06:59:30 UTC: 2.75 MHz Very audible finish here.
