Universal Case Blue Fitting Accessories

Here are some pictures which are being published so that our customers who have purchase the
Universal Case for fitting their Bitx 40 smd could follow the same process as we have not provided any building manual for the case.

So here is the lovely Blue case which has two stereo socket  connectors to be used as Mic/PTT or headphones in any configuration as desired as there are many ways of using the Mic And PTT pins, the way you like.  Like you could use one socket for PTT And Mic since it is a stereo socket and use other one for a headphone, so both purpose can be met,

If you plan to use a baofeng mic then the only problem is that the baofeng mic has two pins, the smaller pin may not fit in the stereo socket as the size will be large for it, on the other hand the big pin will fit okay, so you would need to find a smaller socket, which i could not outsource.

The 10K Linear Potentiometers  for Mic Gain And Audio Gain have to be mounted as in the picture, remember you need to enlarge the holes for both these Potentiometers  slightly with a tweezer so that the 10K LIN  slides into the hole, you may face a problem if you try to fit by turning it clockwise as it may bang with the other Potentiometer, so make it slide with enlarging the holes very slightly.

The stereo sockets also need to be mounted as shown in picture, we could have increased the gaping but then the chinese mic would not fit, so its a compromise.

I am using a Lu5DJV DDS in picture, you could use your DDS with the kit you got it will fit exactly the same way.

The Bitx 40 SMD pcb will be very well placed on the bottom case with ample space from all 4 sides of the case.

The SO239 Connector , Push to on switch And DC Supply and fuse holder all fit very well as in picture.   DC lead is also provided for connecting power to the transceiver.

The knobs can be changed if you have more colorful ones,

I will upload some more pictures soon for other models and colors, hope I have been able to
explain how to fit the accessories

Taurus Delux 20mt SSB/CW receiver video

The Taurus 20mt receiver is working great and I  have monitored the band with many receivers
which are being calibrated with minimum adjustments.

We would like to know if you would like a kit for Taurus? We can also make it for other bands like
40mt or dual 20mt and 40mt. It all depends on what feedback we get.

The Taurus 20mt receiver is available from our ebay store and will also be available from our website.

Our ebay store link for the Taurus 20mt receiver is as below
http://www.ebay.com/itm/Taurus-Delux-20mt-SSB-CW-Receiver-/132224485750?hash=item1ec9318976

I did monitor and record some video too. here is one on our you tube channel.More video soon.

Kindly send us your suggestions if you want the receiver with case and counter, or bare bone RX only?

Taurus 20mt Receiver SSB/CW

Some new kits have been developed by us and are ready to be provided to our customers.

There seems to be a considerable demand for working kits, so we have developed TAURUS DLX
20mt SSB/CW receiver.

The Taurus 20mt receiver works with a single chip MC3362 this RX had been very popular a few years back, we have modified some stages and bought in a kit form working type and the kit type which shall be
available soon, the working Taurus for 20mt will be available from our ebay store and our website.

The Taurus 20mt covers the complete band from 14.000 to 14.350 and the RX performs optimum.
It has also an inbuilt AGC which can be tweaked accordingly. The audio amplifier consist of TDA 7231

Presently the Taurus comes without a case but soon we shall be adding a case to it.

Mounting BITX 40 SMD On Bitx3b Case

We are selling our BITX metal case in various colors, these can be used for our

bitx models like bitx3b 3c etc, these are also good for bitx 40 smd.

Explained below is the method of how you can mount the bitx 40 smd

using our bitx3b case as below.

STEP-1 

Place the bitx 40 pcb in center of the 4 holes which are actually meant for the

bitx3b boards.

Now take a marker pen with a thin and long tip, and make circles inside

the pcb mounting holes and then make new 4 holes on all the 4 mounting holes with 

a suitable drill. If you can not make holes yourself then ask a friend or seek professional help.

                                           Mounting holes for BITX 40 board 

    

                                Mounting holes for BITX 40 board 

                                  Screws secure on the brass spacers

STEP-2 

In the second  step we mount the bitx40 board on the brass stands and secure them with the nuts on 

all four brass stands.

                                                   

   Bitx 40 board mounted on the bottom cover case

                                         

    Bitx 40 board mounted on the bottom cover case

So in easy  two steps we have mounted the Bitx 40 board on the metal case for our 

bitx case.

If you do not wish to make holes on the case then there is a second option of cutting a piece

of copper board and mounting that on the bitx3b case on the pre drilled holes and after that making

4 holes for the bitx board on the copper sheet and mounting the bitx 40 board on the copper sheet with brass stand stands.

The advantage of using our case is that you get sufficient place for adding any other add on circuits

like audio mute control, agc and an extra linear amplifier.

Further we are coming out with some new models that should solve the drilling holes on the

case for bitx 40 smd.

Kindly note we are not in any way selling or servicing bitx40 smd kits. 

New Colors Bitx Case

Two new colors for Bitx Case have been bought into our inventory and are available for sale
from our ebay store and our website 

The two new colors are Black Glossy And DA Grey Glossy.

Hope you would like these two new colors, the case can be used for Bitx 3b3c and for Bitx40 smd.

Bitx from Russia

In our previous post about Bitx from Russia, we had mentioned Nikita building the Bitx 20 3C.

Nikita had promised to send the pictures of his completed Bitx once it was built.

So here are some word from Nikita himself on his Bitx.

" Hello my dear friend! I finished the project bitx 3c sbl-1 20 mt. As promised, I send you some photos of the finished design of the transceiver. Most likely I have mistakes, but it works, and it pleases! Now I wait for some details for multiband bitx, so I'm experimenting with a synthesizer. How I will achieve success I will give details."


Thanks Nikita you have done a great job and and completed your Bitx with lovely pictures of your

Bitx. Hope new hams will find your construction technique very useful and admirable.
