[Kenwood] Need TS-520 history

[rbethman]

The TS-900 has the info on:

Along with a picture.  The element that is missing is the External Power 
Supply & Speaker.  It was a Jones connector as found on MANY radios of 
that era.

You might speculate the TS-500 was an imitation of the earlier Yaesu FT-100 (yes, same model number), the fore-runner of the FT-101. If you carry it back far enough, I think you'll end up with the KWM-1, which, I believe, was the first to integrate the SSB TX and RX into a single box.

So you might ask your question about origins of transceivers (of which everyone will claim their favorite Model XYZ is a classic), or trace the origins. There is probably a Darwinian evolutionary string through which you can see succesful traits (of circuitry or marketing!) that survived and were copied into other designs and products. Then again, that's the topic for someone else's speech, eh?
