Why is there too high cabin noise during Becker AR620X Transceiver intercom/transmit operation?
Excessive cabin noise during intercom or transmission with the Becker Transceiver may occur if the microphone input is too sensitive. To resolve this, adjust the microphone sensitivity to a higher value to reduce cabin noise. After adjustment, recheck the transmit operation and/or intercom function.
What to do if the noise suppression function of Becker Transceiver squelch is not working?
If the noise suppression function of the squelch in your Becker Transceiver isn't working, and receiver noise is always present, it could be due to electromagnetic interference from other avionics. Try improving shielding, increasing distance, or enhancing grounding to reduce interference. Alternatively, adjust the squelch to a higher value, but be aware that this might reduce sensitivity.
How to fix no intercom function on Becker AR620X?
If you cannot hear yourself when speaking into the microphone on your Becker Transceiver, it could be due to several reasons: - The VOX might be switched off or set too high. Adjust the VOX to a lower value; a setting of -15 is generally suitable. - The intercom volume might be set too low. Increase the intercom volume; a value of 37 often provides a loud enough signal. - The microphone input sensitivity might be insufficient. Decrease the sensitivity of the microphone input; a setting of 50–120 mV is usually adequate for most common avionic headsets.
What to do if Becker AR620X Transceiver has no speaker output?
If there is no speaker output from your Becker Transceiver, it might be because the speaker is switched off. Turn the speaker "ON".
Why is VOX threshold not adjustable on Becker AR620X Transceiver?
The VOX threshold on your Becker Transceiver might not be adjustable, and VOX may always be off because the speaker is on. To resolve this, switch the speaker to "OFF".
