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.

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.

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.

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.
