Manufacture

The uBITX boards are hand-assembled by a collective of women [based in Hyderabad, India]. Each of the toroids is hand wound. This provides these women with livelihood. The assembled boards are then DC checked and a final RF check is performed to check the receiver’s sensitivity as well as transmitter’s output before being shipped. Each board is individually numbered. [ 2 ]
