This information is for firmware version 2.47 & greater
Along the top is Frequency, Time (Zulu then Local) & Model of transceiver
Under that is VFO/Mem, Voltage powering CatTouch (helps you monitor the PSU or battery)
The signal bar, under frequency, continually plots around 7 minutes of received signal level
..allowing you check frequency activity at a glance
Bar meters indicate transceiver receive or transmit status
If a bar meter needs calibration, this can be done on the CFG screen
S Bar (Receive Signal Strength Indicator) updates during receive
The next 4x bars only update during transmit:
Watt transmitter power
SWR transmission line standing wave ratio
ALC transmitter ALC action
CMP transmitter speech compressor action
TX Bars are erratic in non-carrier voice modes (SSB) due to slow Yaseu CAT system
All meters accurately report Yaesu CAT levels and are close, but they are not perfect.
They are as accurate as any device monitoring Yaesu CAT meter levels.
On the right side, under volts, is a column of buttons showing current transceiver settings, which you can change, with a simple press
Not all models support all buttons & some modes show irrelevant data (Eg. C4FM on FT991A)
12k - RX Roofing Filter (300, 500, 3k or 12k) Not supported by FT-991, FT-991A or FT-710
ATT - RX attenuator (ATT = Off or 6dB, 12dB, 18dB)
AMP1 - RX front end (IPO, AMP1 or AMP2)
AUTO - RX AGC (AGC = OFF or FaST, MID, SLoW or AUTO)
CNT - RX Contour
NBL - RX Noise Blanker
NCH - RX Notch Filter
DNF - RX Dynamic Noise Filter
DNR - RX Dynamic Noise Reduction
MON - TX Monitor
MEQ - TX Microphone Equalizer
PROC - TX SSB speech processor
LOCK - Keypad Lock
