I originally bought this on eBay around 2008 to use as a ham transceiver -- I'd been off the air for decades, and it wasn't until after I had bought and mounted a multi-band dipole on the rooftop of my apartment building and had a few QSOs that I remembered how boring ham radio is. But this rig has a really superior general coverage receiver, and I've been using it for SWLing ever since. I've compared (just by ear) the Kenwood's reception quality with my Sony ICF-2010 on numerous occasions, and I think they're about the same (as in, "really excellent") -- it's just that the Kenwood is a lot nicer to look at.
The TS-940S has an internal speaker, but a few years later I bought (again on eBay) its SP-940 external speaker unit -- I don't think the external speaker's audio quality is any better than the internal speaker's, but it adds to the gear in the shack, and I usually use headphones anyway.
Manufactured from 1985 into the 1990s, the Kenwood TS-940S has continuous reception coverage from 150 kHz to 30 MHz, and it has numerous controls over reception quality that are missing on, say, the Sony ICF-2010 mentioned above, but then it doesn't have the Sony's unique and amazing Synchronous Detection tuning option, which, seems to me, makes up for almost any other tuning option not found on the ICF-2010.
