Murray Greenman, ZL1BPU, now a silent key, was my guest in Episode 71 more than 5 years ago.  Murray was famous in amateur circles for the development of many popular digital modes.  I spoke to Murray over Skype from his home in New Zealand.  The body of Murray’s work, spanning over 20 years, includes a book, Digital Modes For All Occasions, and on-line content that is very detailed and complete.  Murray passed away in April 2022.  May his memory be for a blessing.
