HF SSB Transceiver
Information
The FT-180/180A is a rugged, compact SSB Transceiver for base or mobile HF applications. Designed to provide a typical PEP power output of 10, 50 or 100 watts over the 1.6 to 18 MHz range, the FT-180/180A employs modem FET and bipolar technology for state-of-the-art performance and reliability.
As many as 6 channels may be installed in the FT-180/180A. Once installation is completed, no further tuning procedure is required for full operation on each channel. The FT-180/180A is packaged in a heavy gauge metal case for excellent mechanical stability, and the final Amplifier transistors are fully protected against possible damage from high Antenna SWR.
