Narrative:

T38 (IFR) at the hold line approach end runway 4, requested takeoff clearance. A BE35 was at taxiway a runway 4. When tower issued takeoff clearance to the T38, the BE35 acknowledged and read back the clearance while transmitting on 119.5. Approach control did not hear this because they were transmitting to another aircraft. The T38 did not hear it because he was on UHF frequency. Both aircraft began takeoff roll. During visual scanning, tower (local controller) saw the bonanza airborne and immediately assigned a right turn 090 degrees to the BE35. The T38 was rolling behind the BE35 and was assigned runway heading by tower. Approximately 3 mins later the tower and approach were successful in getting the BE35 on one frequency. The deviation occurred because the BE35 was transmitting on 119.5 and receiving on tower 118.3. Callback conversation with reporter revealed the following information: analyst learned in the callback that the reporter was working approach control at the time of the incident which was determined to be a pilot deviation.

Title: BE35 PLT MAKES AN INTXN DEP ON RWY 4 IN FRONT OF AND AFTER TAKING THE CLRNC FOR A MIL T38. PLT WAS ON SPLIT FREQS -- RECEIVING ON LCL CTLR FREQ AND XMITTING ON APCH FREQ. TKOF ACKNOWLEDGMENT NOT HEARD BY APCH CTLR. T38 WAS ON UHF.

Narrative: T38 (IFR) AT THE HOLD LINE APCH END RWY 4, REQUESTED TKOF CLRNC. A BE35 WAS AT TXWY A RWY 4. WHEN TWR ISSUED TKOF CLRNC TO THE T38, THE BE35 ACKNOWLEDGED AND READ BACK THE CLRNC WHILE XMITTING ON 119.5. APCH CTL DID NOT HEAR THIS BECAUSE THEY WERE XMITTING TO ANOTHER ACFT. THE T38 DID NOT HEAR IT BECAUSE HE WAS ON UHF FREQ. BOTH ACFT BEGAN TKOF ROLL. DURING VISUAL SCANNING, TWR (LCL CTLR) SAW THE BONANZA AIRBORNE AND IMMEDIATELY ASSIGNED A R TURN 090 DEGS TO THE BE35. THE T38 WAS ROLLING BEHIND THE BE35 AND WAS ASSIGNED RWY HEADING BY TWR. APPROX 3 MINS LATER THE TWR AND APCH WERE SUCCESSFUL IN GETTING THE BE35 ON ONE FREQ. THE DEV OCCURRED BECAUSE THE BE35 WAS XMITTING ON 119.5 AND RECEIVING ON TWR 118.3. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ANALYST LEARNED IN THE CALLBACK THAT THE RPTR WAS WORKING APCH CTL AT THE TIME OF THE INCIDENT WHICH WAS DETERMINED TO BE A PLTDEV.
