Narrative:

On the flight from mem direct gfk, my first officer was monitoring 121.5 on the #1 radio, and writing down the frequencys on his approach chart clipboard (because of terrorist attacks). The B727-100's have only 1 head for each radio, and the volume is on the upper knob. My first officer had a noise reducing head set and numerous times after changing frequencys the volume for the radio would be turned way down, and I would turn it back up. After an uneventful flight and landing runway 35L gfk, tower told us to contact ground on 124.57. I saw my first officer take his pen out and start to write it down. During this time we were doing our aircraft landing checks. I heard my first officer call ground exiting taxiway A2 onto taxiway a. Later I heard him call again 'on taxiway a to the ramp.' I did not hear ground call us so I turned up the volume on the #2 radio and noticed the frequency was 121.75. I asked my first officer if he heard ground answer us and he said no. I stopped and called the tower and he said they had to send a light aircraft around on runway 8 because they couldn't talk to us. Neither ATIS nor NOTAMS gave the ground frequency as 124.57, which could have prevented the incident, they did put it on the next ATIS. Also, ATIS never mentioned landing aircraft on runway 8. 121.75 is the published ground frequency.

Narrative: ON THE FLT FROM MEM DIRECT GFK, MY FO WAS MONITORING 121.5 ON THE #1 RADIO, AND WRITING DOWN THE FREQS ON HIS APCH CHART CLIPBOARD (BECAUSE OF TERRORIST ATTACKS). THE B727-100'S HAVE ONLY 1 HEAD FOR EACH RADIO, AND THE VOLUME IS ON THE UPPER KNOB.

I STOPPED AND CALLED THE TWR AND HE SAID THEY HAD TO SEND A LIGHT ACFT AROUND ON RWY 8 BECAUSE THEY COULDN'T TALK TO US. NEITHER ATIS NOR NOTAMS GAVE THE GND FREQ AS 124.57, WHICH COULD HAVE PREVENTED THE INCIDENT, THEY DID PUT IT ON THE NEXT ATIS.
