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... 73, Stefan Am 15.08.2015 21:16, schrieb Graham: > Hi Stefan > Do you have a link to the CCT for the soundcard Rx ? > > Tnx-G > > http://myweb.tiscali.co.uk/wgtaylor/136SCRX.jpg > > -------------------------------------------------- > From: "DK7FC" > Sent: Saturday, August 15, 2015 6:18 PM > To: > Subject: LF: Some LF again > >> Hi LF, >> >> I'm back there is WSPR-15 for some time.
