Choosing among ham radio transceivers starts with a role question, not just a price comparison: do you need the radio itself, or an accessory for an existing station? The Kenwood TS-520SE is identified as an HF amateur transceiver with SSB and CW. The Yaesu FC-757AT is an automatic HF antenna tuner. Those are different jobs, so the right choice depends on your setup first and your budget second.
Quick verdict
Choose the Kenwood TS-520SE if you need an HF radio unit and want the SSB and CW functions named in its title. Choose the Yaesu FC-757AT if you already have a matching Yaesu transceiver and need an HF antenna tuner with its dedicated cable. The listed prices differ by $100, but this is not a radio-versus-radio contest: one item is a transceiver and the other is supporting station hardware.

Where each product wins
Kenwood TS-520SE

The Kenwood wins when the purchase needs to fill the transceiver role. Its clearly identified TS-520SE model and HF amateur transceiver title make it the relevant choice for someone seeking radio hardware rather than a tuner. The higher listed price is easier to justify when the buyer specifically needs the device category named in the title.
Yaesu FC-757AT
The Yaesu wins when the buyer already has a compatible Yaesu station and needs an accessory rather than another radio. Its automatic HF tuner designation and dedicated connection cable point to that narrower but concrete use case. It also has the lower listed price, provided the buyer is not expecting a transceiver.
Product notes
Kenwood TS-520SE HF Transceiver
The Kenwood is the straightforward pick for shoppers seeking the radio unit itself. Its title names an HF amateur transceiver with SSB and CW, and Auto-Scan appears among its attributes, giving the TS-520SE a specific feature profile beyond a generic radio description. The main limitation is the condition and testing picture: it is used, sold as-is, and may need adjustments or more thorough cleaning. It was not fully tested by the seller, so a buyer should be comfortable with that uncertainty. The Kenwood therefore fits someone who wants the transceiver role and can accommodate possible follow-up work, rather than someone seeking a clearly documented ready-to-use setup.
Yaesu FC-757AT Automatic Antenna Tuner

The Yaesu makes sense as a focused accessory for a matching Yaesu station. It is an automatic antenna tuner for HF use, includes a dedicated cable with a multiplug, and was tested on a few bands. Those details give it a defined purpose for a compatible setup. Its limitation is equally clear: the FC-757AT is a tuner, not a transceiver, so it cannot replace the Kenwood when the goal is to obtain a radio. It is also used and has circular scratches on the top of the case. Choose the Yaesu for its tuner role and connection cable, not as a standalone amateur radio.
Final choice by use case
- Need an HF transceiver: Pick the Kenwood TS-520SE, because its title explicitly identifies a radio with SSB and CW.
- Already have a matching Yaesu transceiver: Pick the Yaesu FC-757AT, whose dedicated cable and automatic HF tuner role suit that setup.
- Want the lower upfront price: The Yaesu is listed at USD 149.99 versus USD 249.99 for the Kenwood, but that lower price only helps if an antenna tuner is what you need.
- Unsure which category fits: Start by deciding whether you need a transceiver or an antenna tuner; that distinction settles this comparison more clearly than price alone.
