The Ignore RX after TX setting specifies a time for which all received frames by the modem will be ignored after
the last TX has ended. This is useful if you want to use the openSPOT3 to link a repeater to the internet through
RF and the repeater has a lengthy internal buffer and it is still transmitting even after the openSPOT3 has
finished transmitting (which means the openSPOT3 will start receiving it's own stream again).
The modem's Sensitivity level can be changed in 6 levels. Note that increasing sensitivity decreases the linearity
of the filters, which may result in incorrectly demodulated bits (which means increased BER). By default,
sensitivity is low (level set to 5 or 6) for modem modes using 4FSK.
The sensitivity of the modem's filter can be changed with the Filter gain setting. Note that increasing sensitivity
decreases the linearity of the filters, which may result in incorrectly demodulated bits (which means increased
BER). By default, filter gain is set to 8.
The modem's AGC (Auto Gain Control) is configured by software for optimal values for low BER in 4FSK
demodulation modes. However, you can turn automatic AGC on with the
Auto AGC setting, but it is
recommended to keep this checkbox off so the openSPOT3's AGC can work on it's own.
When the AGC is turned on, you can set the AGC low/high threshold values. These values will be considered as
low and high thresholds for the Auto AGC circuitry in the modem.
The External VCO checkbox should be checked when an external VCO is applied to the openSPOT3. Currently
there's no external VCO used by the openSPOT3. Note that applying an external VCO is considered as an after-
market modification and voids the warranty of the openSPOT3.
You can also reset all modem settings back to defaults by clicking on the Reset modem config back to defaults
button.
All of the settings above are stored independently for each modem mode in the current profile.
