This is another update on my Tiny Ten transceiver, and particularly one trying to understand noise figure issues with the receiver side. ?I have done noise figure and distortion measurements and posted data. See http://www.janbob.com/electron/TinyTen/TinyTen.htm down near the bottom at, "Dynamic Range, Noise Figure and Distortion" and at, "Noise Figure of the Mixer Alone."
This receiver circuit is closely related to that of the T41 and other QSD projects, so maybe there is other noise figure data around to compare with?? I'm still hunting for the source of about 10 dB of extra noise! ? Any thoughts on this?
