My LPRO is 4 or 5 milli Hz high. I can't see any changes with temperature and my setup swings through 15 F p-p during most days. That's with the electrical tuning open and no adjustments to the mechanical tuning. I couldn't find any specs for the mechanical or electrical tuning range in the data sheet.
