Bitx20 Transceiver

Here, I will explain briefly about this transceiver. This is a design done by Ashhar Farhan, an Indian Amateur Radio Operator and an electronics engineer. It is a bidirectional SSB transceiver. His original design can be found here. This is an excellent 20 meter radio which is quite cheap to build. You can build the entire thing within $15 or around Rs.650/- . You can also find another one of his designs here.

And once this design was released for the public, there were many enthusiasts who devoted their time and tweaked it to perfection. And they formed a Yahoo group called Bitx20. If you are interested in the project, I suggest that you sign up there. You will need a moderator to approve your subscription, but the wait time is negligible.

There are many kit manufacturers promoting this design and you can find some of them here.

QRPKits: A full kit for Bitx20. $90USD.
VU3SUA BITX: Pre wound front end coils and Balun cores, rest of the components has to be bought locally. $8USD or around Rs:300-350 including postage within India. Please contact Sunil Lakhani and he will send you the information required to purchase the board.

Here is a picture of his board.


Or, In case if you like to etch it yourself, the pcb layouts are available within the files section of the Bitx20 Yahoo! group.

So, thats it for today. Good luck on building your Bitx20. Have a good one.
