TX Band Settings overview

The TX Band Settings dialog lets you view and configure per-band transmit parameters on your FLEX-8600, including power limits, tune power, inhibit settings, and external amplifier control. Use this page to tailor TX behavior for each amateur radio band.

Before you start

• A FLEX-8600 radio must be connected and powered on.
• The application must have an active radio connection.

How it works

The TX Band Settings dialog opens a tabbed interface showing one tab per band. Each tab contains transmit configuration controls specific to that band:

• Power limits – Set the maximum power output (in watts) for the selected band. Adjustable from 0 W up to the radio’s maximum.
• Tune power – Set the power level used during tune operations. Typically lower than the main power limit to avoid overdriving the antenna.
• Band enable/disable – Toggle whether the band is available for transmit. Disabling a band prevents accidental transmission outside allowed frequencies.
• Inhibit settings – Control which TX outputs (ACC TX, TX1, TX2, TX3) are suppressed during tuning. Configured via the menu Settings > Inhibit during TUNE.
• External amplifier control – Configure relay and keying outputs for external amplifiers per band.

The dialog is also accessible from the main menu: Settings > TX Band Settings...

The dialog uses a persistent theme container identified as dialog/txBand, which applies consistent styling to the frameless window.

What each control does

Control	Purpose	Default	Valid range	Setting key
Per-band settings (tab)	Shows transmit configuration for a single band, including power limits, enable/disable toggles, and inhibit options.	(none)	(varies by control inside tab)	(none)
Band Enable checkbox	Enables or disables TX on the selected band. Unchecked = TX inhibited.	(enabled)	On/Off	(per-band key internal to radio)
Power Limit slider/input	Sets maximum TX power for the band.	(varies by band)	0 – radio max (W)	(per-band key internal to radio)
Tune Power slider/input	Sets power used during tuning.	(varies)	0 – radio max (W)	(per-band key internal to radio)

Tips

• Use band enable/disable to prevent accidental transmission on bands where you don’t have a license or antenna.
• The Inhibit during TUNE menu lets you suppress specific TX outputs (ACC TX, TX1, TX2, TX3) while tuning — useful to avoid keying an amplifier during tune cycles.
• Changes made in the TX Band Settings are sent directly to the radio; no separate “Save” button is needed.
• The dialog uses the PersistentDialog base class from v26.5.2.1, so window position and size are remembered between sessions.
