Here’s a time line of radios by date of market release with the decade and manufacturer. Take a browse through history! Following the chronology of the radios that Rob has tested on his bench will reveal much about the evolution of amateur radio HF technology. I’ve added links mainly from Rigpix.com to each radio.
Note: I’ve removed duplicate entries from Rob’s Table for simplicity. He tested multiples of a few transceivers as discussed on his website.
