Notes
KW, 49m band, analogue recording on VR Heruntergemischt in Videorecorder-Band, mangels guten Mischers behelfsmäß ig an stark nichtlinear betriebenem BF115 Transistor als Intermodulationsprodukt 2. Ordnung. LO aus Analog-Oszillator Philips GM2883 100mVpp Sinus original 5289 kHz. Digital resampled auf LO = 6075+113.2 = 6188.2kHz. Leider Drifts des LO während der Aufnahme um mehrere kHz, daher Qualität und Frequenztreue nicht gut, aber evt. historisch interessant, da noch deutsche und niederländische, inzwischen abgeschaltete Sender. Eine genaue Charakterisierung des Mischers folgt in nächster Zeit
