I got one of the ebay LPRO-101s about 6 months ago and played with it for a while, but had problems maintaining a lock. First of all, it has a heat sink bolted to the bottom that is just a little larger than the LPRO itself, including being about 1.25" thick( 1" fins). Typical frequency when locked is 10,000,000.007 on a 5360A clocked by a Z3801A.
Both then and now, it takes about 45 seconds to lock from cold, and will stay locked for about 45 minutes. I found that in the position with the heat sink on the bottom will stay locked the longest (up to a few days), but then it becomes intermittent. Other positions will lock for a while, but bottom down always works the longest. For those of you who employed these in TM5xx or similar plugins, did you have lock issues? Is my unit just old?
