  1. The clarifier function use the Tuning knob and DWN / UP keys to change the receiving frequency through the full range of 0.15-30 MHz.
  2. The CW-W mode activates an internal AF filter, while the IF filter is the same as for SSB.
  3. Slightly less on 10-meters band.

FT-757 series :

The FT-757 transceiver, first introduced in 1983, was upgraded with the FT-757 Mark II version. New features include selectable mode-dependent tuning steps, an improved CAT system for more advanced control by computer, a IF notch filter, while the original 500 KHz to 30 MHz general coverage receiver start now from 150 KHz.

FT-757GX-II / SX-II front end protection :

The receiver front end includes a vacuum arc surge suppressor and a lamp fuse to protect the sensitive receiver circuitry from high voltage pulses (EMF) at the antenna terminal. Several thousands of volts can develop naturally when dry Wind or electrical storms create an electrostatic charge on the antenna elements, and this is delivered to the antenna jack if the antenna is connected to the transceiver. In such a case, the lamp fuse may burn out (even if the transceiver is turned off at the time). The only way to avoid this condition is to disconnect the antenna from the transceiver whenever the weather is likely to create high voltage on the antenna.

If the receiver is found to have suddenly lost sensitivity, inspect the filament of the lamp fuse (F1001 on the RF Unit). If it is open substitute with a 8V 100mA pilot lamp. Do not jumper across the lamp fuse terminals however, as this will defeat the protection and could result in serious damage.
