It’s simple, it’s sturdy, and it’s surprisingly powerful. If you’re looking for an “old-school” radio that doesn’t skimp out on modern features, the Kenwood TS-590SG just may be just what you need. In this overview, we’ll discuss the basics of this base station, and help you decide if it’s right for you.
- Great overall TX and RX performance – When it comes to TX, the TS-590SG offers 100W of power on HF, and 25W of power on the 50 Mhz band, and transmits a reliable, clear, crisp signal. It also has a 32-bit floating point DSP and powerful filtering and noise removal features to ensure clear RX performance.
- Simple and straightforward design – If you prefer knobs and buttons to touchscreens, the TS-590SG is what you want. Most of its features are right at your fingertips, with no need to hunt through touch screen menus to find the options you need.
- Great display – The display shows what you need it to, and nothing more. It’s large, crisp, and clear, with minimal clutter. You can even adjust the LED backlight to 10 different tones, ranging from amber to green.
- Rugged design – While it’s intended for use as a base transceiver, the rugged design of the TS-590SG makes it great if you travel with your radio a lot, or if you have a larger vehicle like an RV where you’d like to set up a mobile shack.
- Computer control functionality – The TS-590SG is fully-compatible with the ARCP-590G, which means that you can program, control, and use the radio from your PC, if you prefer. The dedicated USB terminal makes it easy to set up and use the TS-590SG with a PC.
- Excellent value for the price – While it lacks some of the features in more expensive radios like a touchscreen, the TS-590SG is much more affordable, and still provides comparable overall performance, making it a great value pick.
- No backlights on the knobs and buttons – This is a minor issue, but the lack of backlit buttons and knobs means that it may be a little bit difficult to use this radio in dim ham shacks, as well as in mobile applications.
- Old-school design – Depending on your perspective, this can be either a good or a bad thing. If you’re a ham radio veteran, you may love the minimal design and button/knob-based interface of the TS-590SG. But if you’re a newer ham, you may find yourself wishing for a touchscreen, color display, and the other features that have become more and more common on competing radios like the Icom IC-7300. It really depends on your personal preference, though.
The TS-590SG provides reliable, powerful performance in the HF and 50 Mhz bands. It’s not flashy. It doesn’t have fancy bells and whistles like a touchscreen or a real-time waterfall display. But it’s well-built, has plenty of features, and will stand the test of time. It also comes in at about half the cost of fancier radios that have these types of features. If you’re the type of amateur radio operator who prefers old-school radios over modern transceivers that are more like computers, it’s definitely a great pick.
