Test of vertical antenna

I tried to test of vertical antenna that is made of me at the near the beach today.

I made 2 types vertical antennas.
First , I made it that is un- grounded  vertical antenna.
That  specs are very simple.
Antenna element is made of copper wire,Height is about 4m,.
Ground,that's made of grid of iron,about 2.0m * 1.5m ,and add the zinc sheets for 4 direction
.

I measurement this antenna impedance.
That  tuning is about 15.6MHz(parallel mode).

That's is very High Q!!
NEXT, I made a grounded  vertical antenna.
That is supplying to center antenna.just like YAGI antenna.

The imaginary part is starting ”+j(Ω)”,and that inclination curve is very ⊿up.
I think that antenna is not easy to adjust  Z MATCHING.
ANYWAY, I able to get some date of  grounded  vertical antennas.
I am so happy!!!

In the summer.

We are able to see the Milky way in the night sky at the Japan.
I tried to take the photos that photo are the Milky way,Nebula,Meteoric swarm at the 13-Aug-2015-night in the Mt ONIGAJYOU.
Some Japanese Town has lot streetlights.
The small countryside too.
Every time is very bright.
The reason is keeping to protect the public safety.
Since we can't do to searching the stars in the night sky at many the Japan area so easy.
We have to move the dark place to see the night sky.
Then I moved at the nice place and I'v got the some beautiful The MILKY WAY photos and I could to see the Meteoric swarm.
When The shooting star were comeing down .
I felt the cosmos power.
That's  amazing!!
This photo is M8 nebula in the MILKY WAY.

I 'm a SATELLITE STATIONS watcher!!

hello!!

I'v got stuck to watching SATELLITE on my eyes!!
We can see many SATELLITE STATIONS on the air by eyes at after sunset 1H-2H or before sun sunrise 1H-2H.
As you know SATELLITE STATION dose not have  emit light.
The sunlight is reflectioned  by reflex material of SATELLITE STATION(like a solar battery cell).   
When the ground is in the dark.
We can see a reflex of sunlight by SATELLITE STATION easily.
I was able to watching SATELLITE STATIONS.
ISS(The International Space Station),HST(The Hubble Space Telescope),Iridium Satellite stations,etc.
Those are very slow speed to moving air and light is very clear.
I tried to took a photo.
I love to watching   SATELLITE STATIONS. !!lovely

REMEMBER 3.11

REMEMBER 3.11

The 3 years ago,The TOHOKU area of JAPAN was struck by MEGA arthquake and TSUNAMI.

Many people were gone and they got hurt.

I am very sad.

 

At that time, Many Telephone and cellular phone were not able to use it.

Almost Infrastructure was gone.

 

I've heard the news that A few HAM RADIO STATION tried to help by HAM RADIO.

They helped to support emergency communication.

 

I thought that HAM RADIO is very great Communication system.

 

Actually,NEXT TIME, THE MEGA Earthquake and TSUNAMI will attack SIKOKU area of JAPAN as much as soon.

It called The NANKAI MEGA Earthquake. We are afraid it.

 

I live in SIKOKU area of JAPAN(KOCHI prefecture).

I've preparation to communicate of HAM RADIO .

 

The day before yesterday,

I tryed to communicate by HAM radio(7MHz) to communicate of emergency.

I sent cw by low TX power (5w), on QRV to check the condition of HF.

I was able to contact many HAM radio station.

THANKS YOU all stations.

NEXT time, it is my turn.

A1 CLUB WABUN QSO PARTY

I had  joined  A1 CLUB  WABUN QSO PARTY. ( 29.Dec 2013-12.Jan 2014)

WABUN. It mean Japanease code for CW (Morse code).

We can hear WABUN on the HF radio (frequency is 7MHz) in japanese area at the daytime(JST) .

Many Japanease HAM  uses WABUN to communicate each other.

We can get to see nuance easly. It is convenience for me.

But , I 'v heared.The WABUN is not easy to learn to beginner.Those cords are long.(dot and dash)and many.

Anothe reason.few HAMs are not kindness to beginner. For example .They dose not to hit accurate WABUN codes .(We say,It is''NATOOU(納豆) cord") and They starts WABUN QSO,we cannot use it yet.Many HAM beginners hate WABUN,I Khown.

I am beginner.I'v experienced those situation.

But I was not give up!! and Now I can use WABUN easly. I want to do kindness to WABUN beginners.

ENJOY!! SATELLITES!!

I'v got QSO!! via VO-52(HAM SATELLITES)!!

My TX,RX system is very simple.

TX is FT-897DM. TX power is 10W (at:UHF CW). TX ANT was made by me(it is handmade) 6 element yagi.

Rx is simplify all band receiver.Rx ANT is 5 element yagi.

I am useing a straight key.(it is very cheap (secondhand key(¥300($3))))

I have to tune TXorRX frequency by my hand.(manual operation)because

The frequency will be shift by the Doppler effect.

I am very busy!! to operate those systems.(change the frequency dial.hit the straight key and etc・・・・)

I want to many hands!! happy02
