Since this will be a subharmonic design, I wanted to ensure a nice sine-signal for the diode pair. First plan, here, a slightly pulled up 5068.8kHz crystal in a Colpitts oscillator. Somewhat standard, isn't it? The aim is a super clean sine carrier with a frequency of 5069.35kHz. The pull would thus be a whopping 550Hz, that should be doable without any further issues.
Let's see how far I get, how stable it will be and if an oven should be added...
73 for now!
