[hpsdr] GIBRALTAR question.

[peter at gehughes.us]

Hi Rick,
Thanks for the reply.
I suspect that for me, and others, there will be many tradeoffs..between
what we already have, can easily get or have to put on our wishlist..

For my first unit I already have a GPS disciplined Rhubidium. SO I
suspect that I will be making liberal use of my Xacto to "Customize" my
GIBRALTAR..maybe by the end I will be able to build a "Stock"
version....
And anything I cut can always be repaired..

Well this is supposed to be for fun....   :-)
