I am trying to convert my Franklin-based VFO **broken link removed** into a VCO.
I have done it as in the attachment, which works (it oscillates) but the tone in a near by receiver is bad. In AM mode in the receiver it sounds like hum.
I notice that when I touch my hand onto the bare PCB copper the tone gets somehow better (half the hum).
Any ideas?
