I have this Pixie low-power transceiver that I want to add a frequency counter to. I have both units built, but I'm not sure where in the transceiver to tap into the oscillator without affecting it. The oscillator is built around Q1/Y1 in the schematic below. Do I use a low value cap to couple the signal to the frequency counter?
I guess this is the same as asking "Where can I probe the oscillator signal with my oscilloscope?" I can probe at the crystal and get the crystal frequency (or close), but anywhere else and I get different, and way off, readings.
