Narrative:

There was initially some minor misunderstanding regarding the balance 130 radial. I misunderstood it as 132 degrees. This was resolved and the controller verified my correct readback. The controller said 'have a nice flight.' he did not mention a release or void time, nor did he say 'hold for release.' I departed sby. At the time the ceiling was 1000 ft with 5 mi in fog. I called pxt immediately after departure. The pxt controller did not expect me and said that I had used an incorrect procedure, that I should have held for release. She asked if I had departed VFR. At the time I was still in VMC. I had not entered the cloud cover. I leveled off at 700 MSL and turned on course while pxt obtained an amended clearance to fme. The amended clearance was as follows: direct balance direct maintain 4000. I climbed into IMC and completed the flight normally. Analysis: I believe that because of my misunderstanding of a minor point of the original clearance, i.e., the exact balance radial to intercept (130 vice 132) and the necessary back and forth interaction between me and the pxt clearance delivery controller, that the controller forgot to issue release instructions.

Original NASA ASRS Text

Title: CLRNC DELIVERY CTLR FAILED TO ISSUE RELEASE DEP INSTRUCTIONS TO SMA X DEPARTING UNCTLED ARPT. TRACON INTRAFAC COORD. OPDEV.

Narrative: THERE WAS INITIALLY SOME MINOR MISUNDERSTANDING REGARDING THE BAL 130 RADIAL. I MISUNDERSTOOD IT AS 132 DEGS. THIS WAS RESOLVED AND THE CTLR VERIFIED MY CORRECT READBACK. THE CTLR SAID 'HAVE A NICE FLT.' HE DID NOT MENTION A RELEASE OR VOID TIME, NOR DID HE SAY 'HOLD FOR RELEASE.' I DEPARTED SBY. AT THE TIME THE CEILING WAS 1000 FT WITH 5 MI IN FOG. I CALLED PXT IMMEDIATELY AFTER DEP. THE PXT CTLR DID NOT EXPECT ME AND SAID THAT I HAD USED AN INCORRECT PROC, THAT I SHOULD HAVE HELD FOR RELEASE. SHE ASKED IF I HAD DEPARTED VFR. AT THE TIME I WAS STILL IN VMC. I HAD NOT ENTERED THE CLOUD COVER. I LEVELED OFF AT 700 MSL AND TURNED ON COURSE WHILE PXT OBTAINED AN AMENDED CLRNC TO FME. THE AMENDED CLRNC WAS AS FOLLOWS: DIRECT BAL DIRECT MAINTAIN 4000. I CLBED INTO IMC AND COMPLETED THE FLT NORMALLY. ANALYSIS: I BELIEVE THAT BECAUSE OF MY MISUNDERSTANDING OF A MINOR POINT OF THE ORIGINAL CLRNC, I.E., THE EXACT BAL RADIAL TO INTERCEPT (130 VICE 132) AND THE NECESSARY BACK AND FORTH INTERACTION BTWN ME AND THE PXT CLRNC DELIVERY CTLR, THAT THE CTLR FORGOT TO ISSUE RELEASE INSTRUCTIONS.
