New Ham Radio TCVR Minima

Om Farhan from India has come up with another Ham Radio project. The new project is named Minima, which means a project with minimum components.

Minima is a complete ssb/cw tcvr with Arduino in it and an Si570.

Farhan's home page on minima is found here  http://www.phonestack.com/farhan/minima.html

 To carry on with our services we have decided to help amateurs buy our various products based on  Minima.

We are starting by selling the PCB developed by our forum member as very low cost, as to promote the building of Minima. Very soon we will provide a complete kit with case for Minima .

Please look out the availability  of the PCB set for Minima, which will be available very soon on our new blog meant for Minima.  http://cqminima.blogspot.com


We have also set up a new blog for  bitx version 3 B, which will be updated with all info on Bitx3B

Posted here are some pictures of my second built Bitx3B this one is with agc working. The earlier agc pcb had to be modified. The present agc/s.meter pcb mounts on the vu meter.

Bitx Ver 3 B RX demo

Some more new videos of Bitx Ver 3 B in receive mode.

Bitx Version 3 B SSB TCVR . Demo of RX

Here is a video i took last night for the Bitx Version 3 B in receive mode.

I have taken some more videos which i will post soon.

The receiver is quite sensitive and the VFO is quite stable.  Since it is a var actor VFO i am quite satisfied with its stability .  The maximum drift i observed in 12 to 15 hours not more then 50 to max 100 hertz in a period of 12  to 15 hours time.

More news of Bitx Version 3 coming soon.
