There very much is:

    3. A. 2. g. Atomic frequency standards being any of the following:

	1. "Space-qualified";

	2. Non-rubidium and having a long-term stability less (better) than
	   1 x 10 -11 /month; or

	3. Non-"space-qualified" and having all of the following:

	   a. Being a rubidium standard;

	   b. Long-term stability less (better) than 1 x 10 -11 /month; and

	   c. Total power consumption of less than 1 Watt;

The product in question drives directly through the loophole in point 2[1]

Knowledge ?  No.  Some Experience ?  Yes.

The people who wrote the list very much know why they put things
onto it, and in the process of narrowly tailoring the restrictions
often give more away than they probably should.

Depending on your hobbies, you can get some pretty interesting
project ideas by reading the list[2].  (3.A.3 anyone ? or
how about 9.B.6 ?)

The civil servants who administer the lists in the foreign ministries
are seldom rocket engineers and will usually administer the list
strictly to the letter, rather than talk to one.


[1] I've always wondered about that rule and I suspect it is a
    mistake.  Knowing who is on this list, I imagine that the next
    revision will read the far more sensible: "Non-rubidium *or*
    having ..."

Never attribute to malice what can adequately be explained by incompetence.
