For Alaska emergency communications.
Secondary coverage with 10 Watts power output only but high DC power consumption. The FT-847 C2 model has better RF band-pass filter for the 4-meters band.
With optional YF-115C filter.
Individually-optimized preamplifiers are provided for HF, 50, 144, 430 MHz. The FT-847 provides also the capability to deliver +12V/300mA via the 144/430 MHz antenna connectors for external preamplifiers.
Although the FT-847 was not designed for full-QSK operation, the minimum setting of 10 ms delay will be very close to full break-in performance.
