I'm currently using a FT-100 as transmitter. This TRX has a wideband receiver. So I tried to receive the 739 MHz directly.
It worked, but this RX is not sensitive at all on this frequency. Even using an additional SAT-inline amplifier did not move the s-meter a bit when receiving the PSK beacon. But SSB, CW signals were readable.
Let us share more information about RX capabilities of transceivers here.
