Choosing a ham radio transceiver means deciding whether you want a restoration project or a more focused radio for handheld FM use. The Kenwood TS-820S and Kenwood TH-46AT are not interchangeable buys: one is described as a vintage unit with limited testing, while the other is a 440MHz mono-band handheld. The useful question is not which model sounds more appealing, but which format matches the way you plan to use-or work on-the radio.
Quick verdict
The Kenwood TS-820S is the better fit for a shopper deliberately choosing an as-is restoration direction. The Kenwood TH-46AT is the clearer choice for someone prioritizing a handheld 440MHz FM transceiver with a defined single-band format. The listed prices are close, so condition and intended use should lead the decision.

Where each one wins
Kenwood TS-820S

It wins for a hands-on project because the title calls it vintage, the original AC power cable is included, and it powers up. Those details give a restoration-minded buyer a tangible starting point, even though the radio's operating condition is not established beyond power-up.
Kenwood TH-46AT

It wins for a buyer who wants a compact, boxed handheld presentation. The black finish and box are concrete details, and the title's handheld wording supports that format. That makes it a distinct choice from a vintage, parts-oriented radio.
Product notes
Kenwood TS-820S
Kenwood TS-820S suits a buyer who sees the original AC power cable and vintage TS-820S identity as part of a restoration project. The important limitation is clear: the digital display does not come on, and no testing beyond power-up was done. That means the radio should be approached as a repair-oriented purchase, not as a confirmed working setup. The title's Vintage Ham Radio Transceiver wording reinforces the project character, while the model number gives the choice a specific target for someone seeking that unit. Choose Kenwood TS-820S when restoration is the point and the display issue is acceptable; choose the other radio when a handheld format matters more than a vintage repair task.
Kenwood TH-46AT
Kenwood TH-46AT gives the decision a more specific radio target: 440MHz FM on a mono band in a handheld unit. That is the concrete reason to choose it when a buyer's use case centers on that band and mode. The limitation is equally specific: the single-band format does not match someone seeking the TS-820S's vintage restoration direction. The open-box condition and boxed presentation make it a different kind of purchase from a parts-oriented project. Select TH-46AT if the 440MHz FM focus is useful and the box matters; pass over it when the main goal is repair work on an older transceiver.
Final choice by use case
- For a restoration-minded project: choose Kenwood TS-820S. Its title and as-is description point directly toward parts or restoration work.
- For a handheld radio centered on a defined FM band: choose Kenwood TH-46AT. The 440MHz mono-band specification makes its intended format more targeted.
- For the lower listed price: choose Kenwood TS-820S at USD 145.00 rather than Kenwood TH-46AT at USD 150.00. The $5 spread is secondary to choosing between a restoration direction and a boxed handheld.
