[NLRS] Timble Thunderbolts via TAPR

[Doug Reed]

Very interesting! I never even heard of the first group buy. The 
Thunderbolt doesn't seem quite as good as the Z3801 by most of the test 
graphs, but it is much smaller size. They are both in the 1E-12 range so 
it is just a quibble. I've got power supplies that will work with it, so 
I put in an order. For the money, having one more GPSDO isn't going to 
hurt me.... The antenna they sell isn't a domed timing antenna, but it 
is something to start with and for $10 you can add a dome cover of some 
sort. Now I have more reason to finish assembling my portable 10MHz 
source.....

73, Doug Reed, N0NAS.
