It has better audio and filtering than the others, and we supply all of the parts and instructions to let you build it for (or change it to) ANY band of your choice. There are only minor coil and capacitor differences in the simple RF input and oscillator sections of a basic direct-conversion receiver. We give you ALL parts needed to build for your choice of 160, 80, 75, 40, 30, 20, 17, 15, 12 or 10 meters! Try out your own multi-band switching ideas.
