QUOTE from ED: and NONE of the administrivia!
When working, I always said I'd be happy in retirement if I had a good
spectrum analyzer. Well, now after being retired for a bit over a decade
and having lost everything in the 2012 High Park fire....., I have several
SAs....maybe as many as seven.
And, of course, that isn't keeping me happy. Now that requirement has
expanded to several VNAs as well. And, of course, a 1 GHz o'scope from my
retired friend, Ken, from the HP/Agilent/Keysite bunch in the Springs
(Colorado) - the o'scope division.
We MUST have our hands and fingers on good test equipment to be happy, not
just our radios and antennas!! And, of course, I'm a home brewer as well.
Again, the EMC/RFI Lab at ARRL is the best part of the organization.
