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

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.
