Art’s, N2AJO, BitX Project
I really enjoy building different projects for my use in the amateur radio field. I particularly liked this project as it is 80 percent ready to go out of the box. My first build took about 4 hours and I was on the air. My first contact at 5 watts was to PA and Vermont. In addition for those who want to experiment, the radio is hackable which means can be modified to add CW, digital, change freq bands. The cost is $59.00 delivered to your door. I would plan another $50 or so to complete the kit as there are few items that you will need to add. Also attached is a BITX40 Raduino tips and mods document for your review.
