The ARRL Letter reports that Brian Justin, WA1ZMS, of Forest, Virginia, made a 2200-meter contact in April with K3MF in Pennsylvania to have at least one two-way contact on each amateur band from 137 kHz to 322 GHz. Brian informs us that he has since added a contact on 403 GHz!

For some of the higher microwave bands, he needed
to build two radios and give one to a friend to take to a different location to
set up a contact. He used the North East Weak Signal (NEWS) Group standard of
one-kilometer minimum separation to be counted as a valid contact. Justin began
the effort in 2002 and made confirmed contacts on all bands from 160 meters to
300 GHz within a year. The addition of our two newest bands – 630 and 2200
meters – as well as realignment of some microwave bands, required additional
contacts over the years, setting several world DX records in the process, as
well as making the first-ever amateur contact on less-than-one-millimeter bands,
322 GHz and 403 GHz.
