It is mine design, so I have build a couple. It works realy good on CW signals, but SSB is a bit difficult to copy, I think this is usual with DC receivers. You should try building one, there is loads of thing that you learn building this. If you adjust the oscilator, the low pass filter on input has an 3dB point at about 9.2MHz. So with an 80M oscilator, it is possible to make an 80M verson of this receiver. It can also be used on 10MHz, just adjust the oscilator. You might have to adjust the lowpass filter on input when going over 10MHz. It is possible to get this receiver to work up to about 400MHz. 73 de Thomas LA3PNA ter753 wrote: > > Has anyone built this?.
