From latest [Nightly Release - 2023-10-21] onwards it has been added a new check box (next to Roger beep) to the user to be able to select Separated (default) ) / Common freq. RX tuning control respect TX freq., and also another one "Hear Mic" (see attached new updated GUI pictures):
We also added several new features : a new check box (next to Roger beep) to the user to be able to select Separated (default) ) / Common freq. RX tuning control respect TX freq., another one "Hear Mic" (see attached new updated GUI pictures), and small new TX feature, new GUI about IQ TX phase calibration adjustment . (It is in the bottom right part of the screen) : "TX-IQ-CAL", and a TXBW selection in SSB mode :

From last nightly-tag-2024-02-04 onwards, we also added small new TX feature, new GUI about IQ TX phase calibration adjustment . (It is in the bottom right part of the screen) : "TX-IQ-CAL", see detailed description below,

* **F:** This field set the TX Frequency for the transmitter. Use encoder dial to adjust by Step value (uses a default step value, or step value saved in SETTINGS\tx_mic.ini file if "Load App Settings" is enabled). A long press of the Select button allows adjusting frequency digits individually.
* **F_RX:** This field set the RX Frequency for the receiver.
* **FM TXBW:** This field sets the FM Band Width of the transmission under normal conditions from 0-150 kHz. (In fact, it is the +/- FM deviation in Khz.)
* **TXBW:** This field sets the FM BandWidth of the transmission under normal conditions from 0-150 kHz. (In fact,in FM mode it is the +/- FM deviation in Khz that we will apply to the modulator.). Recently , also in SSB mode (USB or LSB) , we allow to the user to set up audio baseband BW to be transmitted (2KHz, 3kHz). (sse annexed example spectrum)
