Affordable QRP Antennas and Kits at exceptional value
The DC40A, 30A, and 20A Transceiver
The DC40A, 30A and 20A series of transceivers are designed by Steve Weber, KD1JV, who is a member of the QRP Hall of Fame. Steve designed these radios to be simple to build and get going, but with surprisingly good performance. They all put out more than 1 W of power with 13.5 volts. The receiver does not use an NE602 series mixer, and thus is almost immune to broadcast interference. The kit comes with all board mounted parts, high quality double sided, plated through, solder masked board. The builder will need to add the case of his choice, and the connectors for power and antenna.
These radios are the next generation of the popular DC40 transceiver that was also designed by Steve. Here are the improvements made:
There is a users group for this series of kits at Yahoo groups. Do a search
for the DC40. We invite you to join, as there is a wealth of information and
help there. This rig is an ideal first time kit for the builder who wants to
get into homebrewing but doesn’t want to risk the family fortune. When you
are finished building this, you will have all the skills to homebrew any of
the more complicated and expensive kits. And, if you like to tinker, this
is an ideal radio for that. Lots of room for experimentation and having fun
