 Ulrich L. Rhode
is a German amateur radio operator and electronics engineer. He is best known
for his work in the development of high-frequency electronics, and his
contributions to the field of amateur radio. Rhode is the founder and owner of
Rhode & Schwarz, a leading manufacturer of test and measurement equipment,
broadcasting systems, and secure communications technology.
Rhode began his career in electronics in the early 1930s. He worked as a
technician for Telefunken, a leading German electronics company, before joining
the German army during World War II. After the war, Rhode founded his own
company, which would eventually become Rhode & Schwarz. The company quickly
established itself as a leader in the development of high-quality test and
measurement equipment.
As an amateur radio operator, Rohde (N1UL) has made significant contributions
to the field of radio communication. He has been involved in the development of
new technologies and techniques for radio communication, particularly in the
area of microwave and RF circuit design.
Rohde has also been involved in the promotion of amateur radio and the
education of new hams. He has written numerous technical papers and books on
radio communication and has been a speaker at many amateur radio conferences and
events.
In addition to his work in amateur radio, Rohde has had a distinguished
career as an electrical engineer and entrepreneur. He has founded several
successful companies, including Synergy Microwave Corporation, and has held
faculty positions at several universities.

AI Technical Trustability Update
While working on an update to my
RF Cafe Espresso Engineering Workbook project to add a couple calculators about
FM sidebands (available soon). The good news is that AI provided excellent VBA code
to generate a set of Bessel function
plots. The bad news is when I asked for a
table
showing at which modulation indices sidebands 0 (carrier) through 5 vanish,
none of the agents got it right. Some were really bad. The AI agents typically explain
their reason and method correctly, then go on to produces bad results. Even after
pointing out errors, subsequent results are still wrong. I do a lot of AI work
and see this often, even with subscribing to professional versions. I ultimately
generated the table myself. There is going to be a lot of inaccurate information
out there based on unverified AI queries, so beware.
