Narrative:
After landing lax on runway 25L, was told to cross 25R and contact ground 121.75. After switching frequency was unable to receive acknowledgement from ground control; stuck microphone. After clearing the runway at taxiway 42 was unable to continue because of widebody transport taxiing wbound on taxiway J. Attempted to call ground again; no contact. At this time an air carrier Q took off on 25R. The noise and shake from his departure was most alarming. We contacted tower and advised of our position and were given an alternate frequency with ground control. 25R runway is only 150' wide and a widebody transport wing span, I believe, extends beyond runway width. The medium large transport length is 109' and it's hard to figure how much room is between 25R and J taxiway. Needless to say, the F/a's in the aft of the aircraft were shaken up. Later, after a call to tower from operations, it was learned that ground control radar was inoperative. I don't need to say how much this increases the dangers of operation at a foggy airport; throw in a stuck microphone and look out. Everyone needs to use caution and be more alert! Suggestions: 1) more people in tower to coordinate better, 2) better equipment, or rather, operation equipment, 3) advise pilots of ground radar out on notes so radio calls will go better.

Title: CLOSE PROX ACR-MLG GND AT LAX AND ACR WDB ON TKOF ROLL.
Narrative: AFTER LNDG LAX ON RWY 25L, WAS TOLD TO CROSS 25R AND CONTACT GND 121.75. AFTER SWITCHING FREQ WAS UNABLE TO RECEIVE ACKNOWLEDGEMENT FROM GND CTL; STUCK MIC. AFTER CLRING THE RWY AT TXWY 42 WAS UNABLE TO CONTINUE BECAUSE OF WDB TAXIING WBOUND ON TXWY J. ATTEMPTED TO CALL GND AGAIN; NO CONTACT. AT THIS TIME AN ACR Q TOOK OFF ON 25R. THE NOISE AND SHAKE FROM HIS DEP WAS MOST ALARMING. WE CONTACTED TWR AND ADVISED OF OUR POS AND WERE GIVEN AN ALTERNATE FREQ WITH GND CTL. 25R RWY IS ONLY 150' WIDE AND A WDB WING SPAN, I BELIEVE, EXTENDS BEYOND RWY WIDTH. THE MLG LENGTH IS 109' AND IT'S HARD TO FIGURE HOW MUCH ROOM IS BTWN 25R AND J TXWY. NEEDLESS TO SAY, THE F/A'S IN THE AFT OF THE ACFT WERE SHAKEN UP. LATER, AFTER A CALL TO TWR FROM OPS, IT WAS LEARNED THAT GND CTL RADAR WAS INOP. I DON'T NEED TO SAY HOW MUCH THIS INCREASES THE DANGERS OF OPERATION AT A FOGGY ARPT; THROW IN A STUCK MIC AND LOOK OUT. EVERYONE NEEDS TO USE CAUTION AND BE MORE ALERT! SUGGESTIONS: 1) MORE PEOPLE IN TWR TO COORDINATE BETTER, 2) BETTER EQUIP, OR RATHER, OPERATION EQUIP, 3) ADVISE PLTS OF GND RADAR OUT ON NOTES SO RADIO CALLS WILL GO BETTER.
