Trying to get my new ham-it-up 125mhz to function.
Checked the voltages, etc per the other posts, they all appear to be correct.
In passthrough I see big 125mhz peak. In upconvert, I see no additional peak.
Voltage across R2 is 0.75V. Voltage across oscillator pins looks correct for upconvert/passthrough.
If I inject signal direct with signal generator, I can see upconversion being done, but it is very weak. 10khz 0.2v doesn't even show up. I have to move it out to ~200khz. And then it shows up around -58db.
Antenna seems operational in passthrough. I can receive clearly FM, VOR, etc.
