BITX20 - 16. Building the external vfo part 2

Ok, finally i got most parts now.... thanks to ebay :) ... i ordered about 1200 capacitors, and the transistors i had a problem with getting where i live, the 2N2369.

A HAM friend of mine provided me with the 2 trim capacitors. which were the last parts needed to fill up the PCB.

Next problem will be the 2k multi turn potentimeter, but there is a HAM fair next weekend again :)
And if i have no luck , another one 2 weeks after that. So i guess this will be easy.

When this is working, I'll start to put the bitx20 together , cause the last part is the PA part, which seems not that time intensive. so maybe this year it will be done. (Remember i never was in a hurry to build this :) )

Redoing the shack.

Redoing the shack..... Well this is not really true...
My shack was close to what people describe when you talk about world chaos....
Lack of storage and time.... and me just dont feeling like doing anything about it, let to an awfull WW3 scenario which i can't even describe anyway....

So as in the beginning of this month was my birthday , i asked my parents to get me storage cases for components. And i got 2 even... and i bought 1 to go along with it.

So now i had no reason anymore to keep postponing the shack.... well.... i did last weekend.... outside temperature of 35c to 37c which causes it to be around 42c in my shack...
So today i started to make sure i would have a presentable shack....
Its not done yet, but the start is here :)

 

The 3 big ones are the new ones. the 2 on the left have resistors in them, capacitors in the right one.

Links on my blog....

When i started this blog, i already noticed that i got hits from other HAM's blogs and sites...
I think the links on each page pointing out other interesting blog's/site's is a great thing.

So i now try to put more effort in getting on people's link pages, and i try to add as much useful links to other people on my links page.
If you want to be mentioned on my link page, please let me know by dropping me an email,comment, or any other message, and i'll add you as soon as i can...

Cheers!

BITX20 - 15. Building the external vfo

I ordered my bitx20 including the LCD frequency counter option.
At that point Sunil included a pcb for a vfo that works together with the frequency counter.

So i started to build this. As no components were included, you have to gather all parts yourself.
My component stock is no where near big , but with the basic stock i have, it almost filled the complete PCB

The components that i am missing are not uncommon ..... i think....
Just som capacitors, 1 coil, variable capacitors, diodes, etc....
So whe i am going to a small hamfair upcomming saturday, i hope to get al parts i need.
If not i still have some ham friends, or online suppliers that can supply me with the parts needed.

BITX20 - 14. The exciter is finished !

I had to make this a separate blog post.....
but the exciter is finally done....

Here it is :)

Now on to the PA part... yeah more coils :|

BITX20 - 13. The output driver

The output driver section was not hard.... even with the coil to be wound...
It was a bifilar, not a trifilar.... so that made it slightly less annoying :)

as this is near the end, i now noticed i am missing a few more things....missing a 100 Ohm and a 1k Ohm resistor. No Clue what i am gonna miss next :)
This for me is one of the charming things of the Indian package. Now if i paid the qrpkits.com price, i would probably mail them for every single item i missed. Now i just took them from my own stock.

As you can see... it is just a small part...

Measurments came out fine, so no worries there!

BITX20 - 12. Xtal section...

Ok , this was hardly any work.... 4 xtal's and 3 capacitors....
No measuring either....

Now there is only 1 section left on the exciter... the output driver.... with a dreaded trifilar coil @#$@#
No time left now to make it. maybe late tonight....
