Yaesu SPA-1 100 W for FTX-1
100 W HF/50 MHz and 50 W 144/430 MHz amplifier with automatic tuner and speaker, for Yaesu FTX-1 Field
The Yaesu SPA-1 is the amplifier that turns the FTX-1 Field into a base station: it raises the power to 100 W on HF and 50 MHz and 50 W on 144 and 430 MHz, with a built-in automatic tuner.
Product description
The tuner works on HF and 50 MHz and protects the transceiver even with less-than-ideal antennas. Two HF/50 MHz antenna sockets (ANT A/B) let you switch from one antenna to another without disconnecting anything.
It has a built-in 2.5 W speaker. It attaches without tools to the rear of the FTX-1 Field, sharing power, signals and CAT control.
