Advice:
The AGC selection will be memorized independently on each VFO stack of the VFO-A and VFO-B.
If the AGC receiver-recovery time is set to the “Off” by pressing and holding in the [AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded.
Quick point: Several aspects of AGC performance may be configured via the Menu. However, because AGC can have such a profound impact on overall receiver performance, we generally do not recommend any changes to the AGC Menu selections until you are thoroughly familiar with the performance of the FT-950.
Terminology: Automatic Gain Control, or AGC, is a circuit that senses the incoming signal strength, and then limits the gains of the RF and IF stages so as to keep the output audio volume at a more-or-less constant level. AGC also protects the RF, IF, Audio, and DSP stages from overload, as it limits the signal strength that is allowed to flow, irrespective of the input signal level.
Mute Feature
There may be occasions, when you want to silence the receiving audio of the FT-950 temporarily, such as to concentrate on what’s being received on the other receiver or telephone call. The Mute feature makes this simple to accomplish.
Press the [(VFO-A)RX] Indicator/Switch while receiving the VFO-A frequency or Memory channel. The FT-950 will be silenced and the green LED in the [(VFO-A)RX] Indicator/Switch will blink.
To restore reception, just press the blinking [(VFO-A)RX] Indicator/Switch once more.
While receiving the VFO-B frequency, press the [(VFO-B)RX] Indicator/Switch. The
