The Current Kenwood Flagship

The TH-D75 is the radio Kenwood ham operators waited four years for. Its the successor of two discontinued models: the dual-band TH-D72 (2010) and the tri-band TH-D74 (2016). Both were killed off together in December 2020 when a fire at the AKM semiconductor plant cut off the converter chips they relied on, leaving Kenwood with no dual-band handheld at all until the D75 shipped in January 2025.

What’s New Since the D74

If you know the D74, the D75 will feel a lot the same: tri-band transmit on 2m, 1.25m, and 70cm, and Kenwood’s industry leading APRS support. It still has D-STAR, and the same wideband all-mode receiver that pulls in everything from HF SSB up through the airband. What changed is the connectivity and the digital feature set:

• USB-C, finally. The D74’s micro-USB (data only) gives way to a USB-C port that both charges the radio and acts as a PC interface — and it can do both at once.
• Two D-STAR streams at once. The D75 can receive two D-STAR signals simultaneously and monitor digital modes on both the A and B bands, where the D74 was limited to one.
• D-STAR without a hotspot. A new DV Gateway mode lets the radio reach D-STAR reflectors over the internet through a phone, tablet, or PC (via USB or Bluetooth), and Reflector Terminal mode makes connecting to rooms straightforward. No separate RF hotspot required.
• Standalone APRS digipeater. The D75 has an APRS digipeater.
• Longer memory names. Memory channels carry 16-character alphanumeric names shown alongside the channel number, double the D74’s 8.
• Much better voice guidance and a Bluetooth headset PTT, plus a refreshed, more ergonomic body.

The TH-D75 does not have full-duplex cross-band operation. The D74 dropped it in 2016 and the D75 still leaves it out, so satellite operators who want to hear their own downlink while transmitting continue to love the TH-D72.

Must Have Accessories

As I mentioned in my initial review, the TH-D75 does not support Bluetooth Low Energy, which became available in Bluetooth version 4.0. From a practical perspective, that means you can’t make a bluetooth connection with an iOS device. So no bluetooth TNC from the TH-D75 to aprs.fi on your iphone. [Georges, WH6AZ](https://radiomail.app/about/) created the [B.B. Link Adapter](https://islandmagic.co/products/bb-link-adapter) to solve this problem. It’s a small hardware bluetooth bridge device which speaks Bluetooth 3.0 for the kenwood, and Bluetooth Low Energy for your iPhone.

With everything turned on (GPS, APRS or TNC) the TH-D75 burns through the battery faster than we would all like. You’ll want another battery for any mission which requires extended operation. You could buy another Kenwood batttery or a third party equivilent. Or you can get the [BP-K75L](https://w0aez.com/products/bp-k75l) from W0AEZ Radio Gear. It has almost triple the capacity of the stock battery, has user replaceable cells, and it’s own USB-C port for charging. It is not compatible with the Kenwood desk cradle (KSC-25LS). Makes the radio chunky, but it will run all day long.
