My first HF radio was a Yaesu FT-450D. This set was perfect to introduce me to the major amateur radio bands, major in the sense of “long distance”. I had acquired it by taking advantage of a promotion that offered the SCU-17 digimode interface. This duo is great, because it makes it quite easy to implement an environment that seems, at first sight, rather complex. I was able to discover and abuse PSK31, HellFeld, FT8, MFSK modes for a few years.
