Buy another one, they are so cheap :-)

Out of the last lot of five that I bought from the same source, four 
work very well and one is marginal - sometimes it locks but it's 
noisy, sometime does not lock.
Lamp and xtal voltage are ok, but it jumps up and down by 1E10. Very 
positive overall, IMHO.
