Bitx20 - 1. The unpacking

It took me long enough but due to a busy last couple of weeks i had no time what so ever to spend on my bitx20.... But today things changed for the better.... i finally have time to start looking start up my bitx20 project.

It had arrived about 2 weeks after i bought it, so the shipping takes some time but not too longs...

For the people wondering why he asks for 25 dollars for shipment...... 
It comes in a cloth bag... with old fashion seals and all... no i am not kidding...
In the bag is a bag , with in there a bag , with in there a few smaller bags , and in them bags with components.....

Ok lets start showing some pics here......
The bag it came in i through away befor i had a photo... here is the bag which came inside of the outer bag...

With in there even more ESD and protection bags....

With in there more bags with components........

Also in the bag the HARDCOPY manuals.... yes... on paper and stuff... not on a cd as pdf or so .... real paper.... excellent!

I was a bit sceptical about the quality i would get from India, but i have to say i was amazed that all this could be put together for the money i paid for it....


Look at these PCB's...

This is the main pcb (front and back)

And this is the amplifier section PCB

 

It all looks very very VERY nice..... maybe not the best pcb out there... but the best you can buy for this much money


Tonight i wont start soldering stuff... but tomorrow i will....
Pictures will be made :) no worries....

Falcon OUT-250B sort of test results.

Hello all,

I did not realy test the antenna yet, but i can not keep you from the few experiences i had so far with this antenna.
As last friday evening I had some time ti sit behind the set, i scanned most of the bands.
20m was open , and i could hear stations from Brazil, Chille, Peru. This is all between 10.000 and 12.000 km from where i live. They all were very clear.
I did not get the chance to make a QSO with them due to huge pile ups caused by our Italian/Russian/Polisch/etc friends. As they all work with huge beams and at least 1Kw......

But, back from naging to the essence....
As i can swap quickly between antennas due to 2 antenna inputs on my TS-480 i could see and hear the difference very well.....
To be honest, with the falcon i could hear those stations perfectly, and i heard nothing on my wire....

The same story goes for 10m... i heard stations on the falcon where on the wire i just heard QRM.


I hope that upcomming weekend i'll be able to do some real test. If you read my blog and want to help me with tests, please drop me a msg or mail.

New project... Bitx 20

Even though i have limited time, i decided to buy a fun kit to have something to do ... yeah right....

I heard a few fellow amateurs talk about a qrp tranceiver called a bitx .... as i had no idea what they were talking about i joined their conversation. They talled me about this little qrp set designed with off the shelf components, and and VERY cheap.

So that night i started to do some research on this set..... and after a few days thinking about it i ordered the most expensive set.... yes... the MOST expensive set. Now get this ... the most expensive set.... is ... hold on.... $75... yes you read it correctly 75 dollars.

Now, i am not going to tell all about it here as there is way enough info on the net...
This is the main site. Ashhar Farhan VU2ESE
And this is the ebay site where i bought it ... Ebay store

If you want a cheaper version.... thats possible....the cheapest kit is ... and again i am not kidding you, check it out yourself.... a whole 30 us dollars......

Well... i got an email saying the kit was send on saturday the second of july.... so i will just have to wait :)

I will keep you guys posted

Falcon OUT-250B the ultimate 20m vertical ?

I promised i would post some test results about the the Falcon OUT-250B i got recently.
And finally i got some spare time to use the set again last night and today.
Now befor you read on, i only have a wire in my backyard to compare it to. it's a Wimo balun (i think a 1:9) with about 15m wire attached. This is the one: Wimo MTFT antenna

As i really like the 20 meter band, I will start my test there.....
And the first thing i noticed.... no signal ? is the antenna broken? No its not!
On 20 meters this antenna is QUIET!....
The signals might be a bit lower then compared to my wire antenna (about .5 to 1 S point) but it does not have a S3 to S5 noise level with it.... I have no idea what you would want, but i prefer to listen to a S5 clean signal then to a S7 with noise in it.

Now, the 20 meter band is also where this antenna switches from good to bad... well bad....
If you expect to work 40M, 80M well on this antenna i  have to dissapoint you.
Experience teaches us that all above 20 meters, you are better off with a wire...
So also with this antenna, it works, but do not expect miracles.
This was confirmed as well when i was listening on the 40m and 80m bands. As soon as i switched to my wire, the signal level went up as well the clarity of the signal.

On the other hand, 17m,15m,12m,10m and 6m all work above my expatiation i had of this antenna.
I do have to say i did not work on those bands  yet, but i did listen to other amateurs there.

Anyway, that's my point of view on this antenna.
If you do not have a lot of space to put multiple antennas up like wire's and beams and verticals etc, and you are stuck with just being able to put op a vertical, then this antenna is really not a bad choice.
Is it the best? i dont know. Is it the worst? for sure not.
Also the 'lack" of radials is awesome when you have lack of space.

Anyway, if you have any questions, do not hesitate to send me a mail or something....

Preparations to put up the Diamond KV-5, a 5 band antenna - PART 3

The fun installation turned out be a complete nightmare.....

The KV-5 was set up at ground level... and it worked really REALLY well.... The SWR was absolutely perfect.  So it was time to put the KV-5 on top of my mast in the back yard.

There it is :)

I was so happy..... But that changed rapidly....
I hooked up the antenna to my ts-480 and tried to tune it.... but.... NO band would tune....
The 5 bands were perfectly set up , but now high above the ground it was totally messed up!

Not having a clue what i did wrong, i wrote an email to Diamond in Japan....
And their answer was pretty clear... "KV5 is required to install at the ground."

I wrote a reply stating my frustration that the manual is not clear at all on the location to install the antenna. There is no note at all that you can not install this antenna on a mast. nor is there a note that you can only install this antenna at ground level.

I called my supplier and he and I came to an agreement that he would take back the KV-5 and supply me with a Falcon OUT-250B , a many band 7,16m long GPA. (google for exact specs....)

So now we have........

I have not had the time to test it really well.... but it tunes on all bands, and it receives more then my weird wire antenna.....
In the upcoming weeks i will see how it works and compares to other antenna's......

The Papers arrived !!!! YEAY !!!

Today my license papers finally arrived. so i am now officially a full licensed ham amateur....
I have been using my new call for the last few days already, i don't really know if i could, but my old call was revoked on the site already, my new call was there, and even QRZ was already automatically updated.

I will scan the license later to put it up here.... Can't help being proud of myself that i managed to motivate me to get my Full license after having my Novice license for about 16 years already.

Preparations to put up the Diamond KV-5, a 5 band antenna - PART 2

Even though it was really hot outside in the sun , i did some more preperations for putting up the antenna.
I did not make any photo's yet, so I'll add them later.

I started out with a nice trip to the local DIY supply store called Gamma.
I needed some copper pipes,  2 2m pipes, Special ground wire (5 mm wire used in electrical installation)
And some other small parts....

I started with putting the copper pip into the ground... Using water as "drill" you can push 4 meters of copper pipe into the ground EASY.... Don't go deeper with the copper pipe then needed. Copper pipe no goes for 11 euro for a small 2 meter pipe which is the smallest pipe (12 mm).
when that was done i connected the ground wire to the lower wall bracket.
Of course the wire runs through a grey PVC pipe.

When that was done I started to prepare my 6meter long mast pipe. I wanted a possibility to hose a wire antenna to the top, so I made a rope installation.

Tomorrow probably will be the final day of installing the antenna... finally.... but it is said to be really hot again.... If its too hot then i will wait till Sunday where it will be a bit less hot.

Photos will follow later.
