S.Meter For Your Bitx

Many of the modules are ready that can be added to your Bitx or any other home- brew RX. The S,Meter is an important display to let you know the signal strength of the signals being received.
Two interesting kits have been made for S.Meter.
The First is the Bar Type S.meter and the second one developed is LED type one that has four LED.

I am publishing some pictures here and the links for purchase of the S,Meter kits will be placed soon.

More Kits and modules coming up on my next posting.

My Sincere thanks to Tony Fletcher for designing the PCB for all the modules :)

Best Regards

Bitx Version 3 By Toni exec5abg

'WOW' is the expression for the Bitx Version 3 build by our friend Om Toni exec5abg.
I must say that the construction is great, in fact all our Bitx Builders have a unique style of building their rigs and the sheer dedication exhibited is just great.
Enjoy the excellent and beautiful pictures submitted by our good friend Toni exec5abg.

DDS For Bitx

It gives me great pleasure in presenting the DDS. which has been made and documented by my good friend Tony Fletcher MOPKD from United Kingdom. The PCB will be available soon.

The kit will also be available later. Tony has put in his comments:-


The dds is the only one available using conventional components the rest are surface mount ,this was built with Bitx in mind ,the construction is solid and good and offers features many other dds units do not have such as keypad entry ,band switching for filters and switching of modes for filters .
The specifications of the dds can be found in the dds v4 notes ,the dds was not designed by myself ,but i merely made the pcb designs to allow others to be able to make this for use with a radio receiver ,transceiver ,or stand-alone unit ,
The design allows both AD9851 and Ad 9850 ic to be used the Ad9850 will give 36mhz output with a 80mhz osc and the Ad9851 with onboard multiplier will give 81mhz max frequency with a 30mhz osc ,the design will take both half and full sized osc .

Update On Bitx Cabinet And Modules

The Bitx modules for Multi-band are ready and will be out soon. With
these modules you can make Bitx a Multi Band TCVR . Also we are coming up
with a DDS that should make it more easier.

After we get feed back on modules working with the Bitx then only we
will go ahead and make a new Pcb design with the modules integrated.

These modules can be used for any home brew project and are as add on.
The new Bitx cabinets are under construction and soon you will have a
few models to choose from . These cabinets will be
self assembled ones, i.e the Cabinet will be in 6 parts and can be
assembled, hi hi
Wish you all the best

Bitx Version 3 From U.K By Nigel G0EBQ

Nigel G0EBQ from U.K has build his Bitx Version 3 and I am very glad in publishing the picture of his Bitx and his kind comments below:

"This is my 12m version of Sunils excellent kit which is working fine and is under air test.I will post details on Yahoo of the modifications,which ought to work also on 15m,and a further photo when it is properly cased up.
Building the kit from scratch has certainly taught me a lot about both theory and practice! Many thanks to Leonard KC0WOX for his superb instruction manual."

Popularity Of Bitx Version 3

The popularity of Bitx has been increasing with Hams around the world trying to build this fabulous Qrp wonder.
Some Hams in continents like Africa and South America have yet not ventured into the Bitx version 3. It would be interesting to get a feed back from them as what problem they are facing in getting the Kit, is it that Paypal is not accepted in their countries or they have not heard much about the Bitx.
But Hams mostly from U.S.A and Europe have been leading in building the Bitx version 3.
Japan has also a great number of Hams, but its amazing that the Bitx Version 3 has not been constructed by any Japanese Hams.
I hope in due course of time more Radio Amateurs will relish making the Bitx version 3.

News on modules and complete Bitx kit

It has been a fantastic response for the new complete Bitx version 3 kit.
I would like to thank all my friends who have purchased the complete Bitx
Version 3 kit.

Any feedback from members will be most welcome, so that I could provide value for the ohms spent on the kit.

If you would like certain parts more to be included in the kit, then do send me
A mail so that I can consider the new item to be added to the kit.

The modules are being tested.Very shortly a complete range of modules to make the Bitx a multiband or enhance its features by adding LED for S.Meter indication, with normal LED or Bar type LED will be available.

Some modules that are being tested are DDS, Band Pass Filter, Low Pass Filter,
AGC,S.meter Led type. S.Meter Bar type,New Linear with more drive for the IRF510.
Huff and Puff Vfo stabliser,CW Module,Mic Amplifier are some of the interesting modules to be added soon for sale.
I will be back very soon to put up the buy buttons for the modules.
