Content preview: Thank-you, Michel. Good conditions and no mention of a chip, nor could I see one on your spectrum. Yesterday I changed the TX and hopefully fixed the chirp and maybe the phase glitches? There are still bumps (~0.1 Hz) in the spectrum 10 MHz DOCXO output every few minutes. They last longer when the osc is less thermally insulated from the shack, but this is unchanged by putting a big cap across Vcc (which is unchanging). Could this be the source of the phase instability in the 137 kHz sigs? How about a large AC ripple on the supply to the PA?
