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
