Narrative:

We lost communication with ZDV while doing the dandd arrival to den. We switched radios and frequencys and made intermittent contact but lost contact before complete messages could be received. We did acknowledge receipt on 1 transmission by squawking identify. After exhausting all available frequencys, we contacted ZDV on guard and received a frequency that established at least intermittent contact. At that time an ACARS message was received telling us we had a stuck microphone. We switched to the captain's hand held microphone and established communication without interruption. Landing was uneventful.
