Narrative:
During a flight from slc #2 airport, while transporting parachute jumpers to jump altitude, the primary radio malfunctioned. At this time I tried using a hand-held radio that was on board the airplane. The controller said that he was receiving my xmissions but that they were very poor with lots of backgnd noise. I was having the same problems receiving his calls. The controller then cleared me through class B airspace to 7500 ft MSL (first jump altitude) and then to 14000 ft MSL (second jump altitude). This series of xmissions was extra difficult to discern. After dropping the first jumpers at 7500 ft MSL and reporting jumpers away and continuing climbing to the next jump altitude the controller informed me that he had given me an altitude restr of 7500 ft MSL. I contribute the problem to using a radio that was not adequate to hear the controller's complete instructions, and feel it would have been best to have returned to the airfield after losing use of my primary radio.

Title: PLT OF AN SMA SEL PARACHUTE JUMPING ACFT INADVERTENTLY CLBED ABOVE ASSIGNED ALT PRIOR TO BEING CLRED.
Narrative: DURING A FLT FROM SLC #2 ARPT, WHILE TRANSPORTING PARACHUTE JUMPERS TO JUMP ALT, THE PRIMARY RADIO MALFUNCTIONED. AT THIS TIME I TRIED USING A HAND-HELD RADIO THAT WAS ON BOARD THE AIRPLANE. THE CTLR SAID THAT HE WAS RECEIVING MY XMISSIONS BUT THAT THEY WERE VERY POOR WITH LOTS OF BACKGND NOISE. I WAS HAVING THE SAME PROBS RECEIVING HIS CALLS. THE CTLR THEN CLRED ME THROUGH CLASS B AIRSPACE TO 7500 FT MSL (FIRST JUMP ALT) AND THEN TO 14000 FT MSL (SECOND JUMP ALT). THIS SERIES OF XMISSIONS WAS EXTRA DIFFICULT TO DISCERN. AFTER DROPPING THE FIRST JUMPERS AT 7500 FT MSL AND RPTING JUMPERS AWAY AND CONTINUING CLBING TO THE NEXT JUMP ALT THE CTLR INFORMED ME THAT HE HAD GIVEN ME AN ALT RESTR OF 7500 FT MSL. I CONTRIBUTE THE PROB TO USING A RADIO THAT WAS NOT ADEQUATE TO HEAR THE CTLR'S COMPLETE INSTRUCTIONS, AND FEEL IT WOULD HAVE BEEN BEST TO HAVE RETURNED TO THE AIRFIELD AFTER LOSING USE OF MY PRIMARY RADIO.
