I can only hear on one side of the ear (KA-1)

If the plane has a "Mono" system and the headset is in "Stereo" setting, the headset will only output in one ear. Switch headset setting to "Mono" in the switch box in the middle of the cord. Only a "Stereo" intercom with KA-1 in "Stereo" setting will output in both ears.

My microphone is intermittent or doesn't transmit

If microphone doesn't transmit right away, please check the squelch setting found on the plane's intercom. Squelch is what sets the noise gate to turn the microphone "hot" and transmit. It could be that the squelch level is set too high and not letting all or beginning of the transmission to go through. If microphone is not transmitting at all or it's intermittent not at the beginning of the transmission but throughout and you've checked the squelch, please contact and we can proceed with a microphone replacement.

I cannot hear my own transmission

This is sidetone, a feature that repeats back your transmission back to your ear and it's found on the plane's intercom. The headset does not have a way to turn on or off this feature.

Can I talk on the phone using the 3.5mm aux jack?

No, the aux input is for audio only to listen to music, podcast or navigation from your phone or other mobile device. While you will be able to listen in on the headset speakers, you will not be able to use the microphone to talk on the phone.
