The Trio TR-300 is a mobile 6 meter transceiver, probably intended for the Asian market. The TR-1300 transmits in SSB only. Some sources state RF-output is 5 watts, but actually was only 1.5 W max, using an 2SC1306 output transistor.
There was an optional linear amplifier available giving 10 W output. It used the 2SC1307 output transistor. The amplifier was housed in the same dimensions case as the TR-300, with only a different front panel.
