FLEX-6000 Signature Series – Maestro User Guide

The hardware ALC can be enabled and disabled by tapping on the Hardware ALC button.

Δ – Please note this input is provided as a safety measure for external amplifiers. It is NOT meant

to be used in regular operation as an active power control input or to modify the “attack” of an

external amplifier. Almost all modern HF amplifier manufacturers discourage the use of ALC in

normal operation. Many amplifiers do not have ALC implemented.

The Show Tx in Waterfall button enables and disables the display of the transmitted signal in the

Panadapter Waterfall. When disabled, a single white line is added to the Waterfall when

transmitting. When enabled, the transmission data is added to the Waterfall.

The Max Power control allows the user to manually set the radio’s maximum output power on

ANT1 and ANT2 when using the PA. This control sets the maximum value of the RF Power front

panel knob. Transmit power set by third-party programs will be limited to this value.

The Timings section has adjustments for RCA TX1, TX2, and TX3 (only TX1 on FLEX-6300) as well as

the Accessory TX, TX Delay, and TX Timeout. Each of these controls is measured in Milliseconds

(ms). Each of the TX1, 2, and 3 timings acts independently and starts measuring from the moment a

microphone PTT switch is depressed, a CW paddle is keyed, etc. RF is transmitted as soon as the

largest of the TX1, 2, 3, and ACC_TX delays have elapsed if the TX Delay is set to zero. Otherwise,

the TX Delay value is added to the maximum of TX1, 2, 3, and ACC_TX. Note that each of these

timing settings is global to the radio. Whether the fields are active is set by band on the TX Band

Settings tab. See section 33.8.

When TX Inhibit is enabled, the transmitter is prevented from operating, regardless of other

settings and inputs.

The MIC2 PTT button allows the user to disable the PTT input on the MIC2 back panel jack. This is

useful when a microphone without a PTT switch is used.

The Interlocks section offers three settings for RCA and Accessory timings: Disabled, Active High,

and Active Low. The FLEX-6300 does not have interlock settings for RCA.

When the Transmit Equalizer is enabled, the transmitted audio can be optimized for different

microphones and operating styles such as DX, contesting, and SSB. The sliders provide a +/- 10 dB

adjustment range over eight octaves. The settings shown above provide very good audio quality

for many dynamic microphones.
