Re: VFO Output – Is This Right???


Thanks, Jim.  Scope is 150 MHz, but I just soldered some wires onto the CLK0 pads and attached the scope probes (1X) to the wires.  I'll try some of your suggestions when I redo the measurements.  What do you think of soldering some 50 ohm coax to the pads and then connecting the coax to the scope probe?

I was hoping to use this VFO for tuning a homebrew HF QRP transmitter (and driving a following buffer & amp).  I was more worried about the attenuation than the waveform.  Thanks again.
