Are there many amateur radios using Bluetooth yet? I have looked around a bit and it seems pretty scarce, so far. Bluetooth seems very common with cell phones, but rather uncommon in two way radios, either amateur or professional.
Yes, the Kenwood TH-D74 has Bluetooth standard. I have not used mine with a Bluetooth headset, but the problem with Bluetooth cell phone headsets and two-way radios is dealing with the PTT. VOX is a possible solution. The TH-D74 Bluetooth works great as a Bluetooth serial port for an external APRS program, TNC access in KISS mode (I've used it with Winlink Express), and for programming the radio.The Kenwood triband thd 74A handheld comes standard in the US model with bluetooth.
