[hpsdr] GIBRALTAR question.

Sun Jul 9 17:31:48 PDT 2006

Hi Rick,
Thanks for the extra effort...I hope it works for more than just me...

AND 

I like your idea of using one size of holes for all 3 types of
connectors..Amphenol uses 0.067 for all 5 holes inspite of the size of
their center pin (0.050) and I also like that they are thru hole mount
connectors..We are always having problems  with the center pin pad
detaching for edge mount connectors.
