The circuit comes from the Yaesu FT-480R 2m transceiver so would have worked as designed. I certainly agree that the oscillator on the bread board wasn't tuned to create the 3rd overtone, I was simply testing the crystal to see if it worked at all. To see it oscillate at the fundamental seems to show the crystal is ok so I'm looking at why it doesn't it work in the PLL unit. A thought I had was that maybe a crystal can be harder to get to oscillate at the overtone rather than the fundamental.
