If your Icom IC-210E radio is transmitting well but suddenly no longer receiving despite the antenna and fuse working properly, calibration may not necessarily be the issue. However, if you suspect that calibration is the problem, here are the steps you can follow:

1. Put the radio into "calibration" mode: To do this, press and hold the "FUNC" and "CAL" buttons while turning on the radio.
2. Tune the radio to a known frequency: Use a frequency counter or another radio to find a known frequency that the radio should be able to receive. Tune the IC-210E to that frequency.
3. Adjust the trimmer capacitor: Use a small non-metallic tool to adjust the trimmer capacitor located on the back of the radio. Turn it slowly in either direction until you start to hear a weak signal.
4. Fine-tune the trimmer capacitor: Continue to adjust the trimmer capacitor until you get the strongest signal possible.
5. Exit calibration mode: Once you have completed the calibration, turn off the radio and turn it back on to exit calibration mode.

If the issue persists after calibration, it is possible that there may be a problem with the receiver circuitry or other internal components of the radio. In this case, it may be necessary to take the radio to a professional technician for repair.
