Narrative:
We were coming in on the initial ILS approach for runway 31 into rst. My first officer wrote down the incorrect altimeter setting due to hard to understand weather read out on frequency. Current altimeter setting was 29.21; he relayed 30.21 for our settings which put us 1;000 feet below assigned altitude. We broke out and I initiated a climb and asked for current altimeter at the field from approach control. They said low altitude alert; and gave me current altimeter setting. We continued the approach and landed safely. It was a CRM mistake; because my first officer didn't tell me he couldn't fully understand the weather. That way I could have helped listen for clarification on the correct setting.
