Article about Black Holes in
the Air was published in Antentop Magazine http://www.antentop.org/black_holes.htm. As I mentioned there I did not observe Black Holes in
the Air. At those times I say no. Times lasts.
…It happened in March- 2013. I do not remember exactly day because
my paper about the observation was lost at one of my moving. Anyway
I remember hour when it happened. It was at 21.00.
I went to my shack and turned on a computer (to do some routine).
Straight away I turned on my lovely tube receiver HALICRAFTERS
S- 85. (I have a habit to listen receiver when I do some work.)
At that time the receiver was tuned to 640- kHz, I listen to Coast
– to- Coast Radio. So, I turned on receiver
to listen the radio. However several
minutes past but receiver was silent.
I turned frequency dial around all MW Band. There was only a
noise no any station. I switched MW Band to SW one. It was the
same story- roar and noise, no stations on the bands. I thought
that something wrong happened with the receiver or my antennas.
I turned on my transceiver IC-718. It was no reception on HF-
Bands. I pressed transmit and checked SWR on the HF bands. SWR
was ok. FSM (I used MFJ- 801) as well showed that everything okay.
At that times I used Helical HF Antenna (Helical
Antenna for the 20- meter Band, http://www.antentop.org/017/va3znw_017.htm)
and L- HF Antenna (Simple Broadband Antenna for the
40- meter Band,
Now I use to a Beverage Antenna at my ham station VA3ZNW.
What is interesting I discovered significant improvement of reception
during a heavy snowfall, snow with rain, and at light rain. This effect was observed at evening and night time
(because usually I do not hamming at day- I am at my work). At
the weather the noise in the Air drops down and propagation to
Europe go up at 160, 80 and 40- meter Bands. This effect does
not connect with solar conditions. When weather would improve
the propagation disappeared. It does not connect with Black Holes,
I went outdoor check antennas. There was very strong mist. Antennas
visually were okay. I returned to shack and turned on VHF FM Receiver.
Yes, I can hear FM stations however with some strange distortions.
Cable TV and Internet worked well. I tried to found some information
on the phenomena in the internet. Only found that there were solar
flares. While I went around and checked internet the HALICRAFTERS
began to be alive. Something from far I began hear stations, through
several minutes reception on MW and HF-Bands was as usual.
What I observed at that day- it was almost full blackout on MW and
HF for near 40- minutes.
