Narrative:
I was working the coordinator south position at shreveport RAPCON tower. At approximately XX02 UTC, I instructed shreveport local control to have all departures maintain 2000'. At approximately XX08 UTC, shv local control advised that MTR was departing runway 32 at shv. An small aircraft was level at 3000' 3 mi northwest of shv eastbound. An MTR reported on frequency, 'climbing to 3000',' but the radar controller was on the landline and did not hear MTR's call. The MTR was radar idented and then I noticed MTR climbing out of 2200'. I immediately called this to the attention of the radar controller. He instructed the MTR to maintain 2000'. The MTR said he saw the traffic and descended back down to 2000'. There was training on both local control and radar south which was the departure controller.

Title: APPARENLTY A BREAKDOWN IN INTERFAC COORD--RADAR COORDINATOR SAYING ONE THING AND LCL CTL HEARING SOMETHING ELSE (2000 VERSUS 3000').
Narrative: I WAS WORKING THE COORDINATOR S POS AT SHREVEPORT RAPCON TWR. AT APPROX XX02 UTC, I INSTRUCTED SHREVEPORT LCL CTL TO HAVE ALL DEPS MAINTAIN 2000'. AT APPROX XX08 UTC, SHV LCL CTL ADVISED THAT MTR WAS DEPARTING RWY 32 AT SHV. AN SMA WAS LEVEL AT 3000' 3 MI NW OF SHV EBND. AN MTR RPTED ON FREQ, 'CLBING TO 3000',' BUT THE RADAR CTLR WAS ON THE LANDLINE AND DID NOT HEAR MTR'S CALL. THE MTR WAS RADAR IDENTED AND THEN I NOTICED MTR CLBING OUT OF 2200'. I IMMEDIATELY CALLED THIS TO THE ATTN OF THE RADAR CTLR. HE INSTRUCTED THE MTR TO MAINTAIN 2000'. THE MTR SAID HE SAW THE TFC AND DSNDED BACK DOWN TO 2000'. THERE WAS TRNING ON BOTH LCL CTL AND RADAR S WHICH WAS THE DEP CTLR.
