Narrative:

Military X took off from beale and usually is on the pynun departure. This time he was rerouted direct to mustang which put him in conflict with air carrier Y at FL310 who was on a 325 degree heading for klamath falls. Military X was climbing out of FL285 for FL600 when I was alerted to his turn to the east. I asked military X how fast he could be out of FL330. I thought he said 1 min, but later learned he said about 1 or 2 mins. I then told military X to report leaving FL330. I also made another mistake at this point, because I thought I said report leaving FL330 in 1 min or less. Needless to say, it didn't work. Before listening to the tapes I was thinking this was a pilot deviation believing I had said report leaving FL330 in 1 min or less. I might add that there was heavy frequency congestion on my discrete frequencys (VHF and UHF). It was so bad at times, I couldn't make out any aircraft idents.

Original NASA ASRS Text

Title: MIL X CLB THROUGH OCCUPIED ALT, HAD LTSS FROM ACR Y. SYS ERROR.

Narrative: MIL X TOOK OFF FROM BEALE AND USUALLY IS ON THE PYNUN DEP. THIS TIME HE WAS REROUTED DIRECT TO MUSTANG WHICH PUT HIM IN CONFLICT WITH ACR Y AT FL310 WHO WAS ON A 325 DEG HDG FOR KLAMATH FALLS. MIL X WAS CLBING OUT OF FL285 FOR FL600 WHEN I WAS ALERTED TO HIS TURN TO THE E. I ASKED MIL X HOW FAST HE COULD BE OUT OF FL330. I THOUGHT HE SAID 1 MIN, BUT LATER LEARNED HE SAID ABOUT 1 OR 2 MINS. I THEN TOLD MIL X TO RPT LEAVING FL330. I ALSO MADE ANOTHER MISTAKE AT THIS POINT, BECAUSE I THOUGHT I SAID RPT LEAVING FL330 IN 1 MIN OR LESS. NEEDLESS TO SAY, IT DIDN'T WORK. BEFORE LISTENING TO THE TAPES I WAS THINKING THIS WAS A PLT DEV BELIEVING I HAD SAID RPT LEAVING FL330 IN 1 MIN OR LESS. I MIGHT ADD THAT THERE WAS HVY FREQ CONGESTION ON MY DISCRETE FREQS (VHF AND UHF). IT WAS SO BAD AT TIMES, I COULDN'T MAKE OUT ANY ACFT IDENTS.
