If it was working, what to u think the JFETs in the guy's working circuit should be doing with no input ?
I'll try new JFETs, but maybe it's just I haven't used a strong or high-freq. enough signal. I just made a little crystal oscilattor. If I just try amplifying that a few times, but to what level ? And if I actually make something that can drive 50 or 75ohm load, what current and voltage is that at

Is this thing meant to work with AC input coupling as well ? The 56ohm resistor on the mixer JFET is only 1/4 atm, I don't see any big resistors in his case.
Aside from the ramp gen, should anything be oscillating from say a tank circuit when the circuit is turned on ? Should the LO be doing anything? Or does it only follow an input frequency? If this was an all BJT circuit, I'd know what to expect a lot better.
I made Mr.Carlson's Super AF/RF probe, it works great. It doesn't hear much from the 555 SA.
On XY mode, I though I found something that looked like it might be real, but I was looking at clouds.
So if the JFETs were biased about right, when turned on, roughly what should the DC voltages be on GDS, and several of those are on Vcc and GND
I must experiment with single JETS
