History
The BITX transceiver was originally developed by Ashhar Farhan for Indian hams -- who have often been handicapped by a lack of low cost equipment -- to get them on air.? A mono-band, bi-directional, design using ordinary NPN transistors was developed to cater to this demand.? The design could be adapted to any particular ham band by changing the RF section coils and capacitors and the VFO frequency.
BITX evolved over one year from the excellent S7C receiver described in the new ARRL book ‘Experimental Methods in RF Design’ (an ARRLpublication) into a bi-directional transceiver.? Several expert hams across the globe contributed to its design and this resulted in a sensitive receiver capable of strong signal handling and a stable and clean transmitter capable of enough power to make contacts across the world.
Through the years, the design has been homebrewed and kit built by many hams, and new more advanced kits have been further developed by Ashhar Farhan to bring the original design into the exciting world of microprocessors, software programming, and digital amateur radio modes.
