The circuit board is populated and only requires the addition of external components for tuning, audio input, power, antenna and other connections. A case of the builder's choice is also required.
For the price of $45, it seems to be a good deal. And from the designer, Ashhar Farhan VU2ESE:
The BITX boards are hand assembled by a collective of women. Each of the toroids is hand wound. This provides these women with livelihood.Instructions for completing the project are available online and alignment seems simple enough, if needed at all - the boards themselves are shipped pre-aligned.
Output is 7 to 20 watts depending on power supply voltage.
