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

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.


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


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

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.
