FUNCTIONS FOR RECEIVE | 5 |
The preamp amplifies received signals in the receiver front end, to improve the S/N ratio and sensitivity. Set this to preamp 1 or preamp 2 when receiving weak sig- nals.
➥Push [P.AMP] (MF3) several times to set the preamp OFF, preamp 1 ON or preamp 2 ON.

✔About the “P.AMP2”The “P.AMP 2” is a high gain receive amplifier. When the “P.AMP 2” is used in the presence of strong electromagnetic fields, distortion sometimes results. In such cases, use the transceiver with the “P.AMP 1” or “P.AMP OFF” setting.
The “P.AMP 2” is most effective when:
•Used on bands above 24 MHz and when signals are weak.
•Receive sensitivity is insufficient when using
The attenuator prevents a desired signal from distortion when very strong signals are near the desired frequency or when very strong electromagnetic fields, such as from broadcasting stations near your location.
➥Push [ATT] (MF4) several times to set the attenuator 6 dB, 12 dB, 18 dB or attenuator OFF.
➥Push and hold [ATT] (MF4) for 1 sec. to turn the at- tenuator function OFF.
