The beauty of Opera is that it is really easy to set up as it simply 
uses on-off keying. If you can run QRSS you can run Opera. Other digi 
modes can be useful but require additional complexity. It also 
provides instant comparison reports with other stations so it can be 
a great incentive to improve both transmit and receive performance.

I also officially retire this year (hooray!), though I have been self-
employed / part-time / work from home for a decade now.
