Hi G,

No, i've made to many modifications from time to time. There is no up to date schematic. But, it is a typical design. A suitable band pass filter, impedance converter matching to a SBL-3 mixer. The LO is 125 kHz, down-divided by a CMOS 4060 and a 4 MHz xtal. Then an IF-LPF. That's all. You may need an additional amp stage, depending on the incoming signal level...

Hi LF,

I'm back there is WSPR-15 for some time. The power is reduced by 4 dB, unfortunately.

Maybe someone can catch a trace anyway :-)
