HE INFORMED ME THAT I HAD DONE 2 UNAUTH TOUCH AND GOES AND THAT AFTER I CALLED R BASE FOR RWY 34 MY MIKE BUTTON HAD STUCK AND HE COULD NOT XMIT OR RECEIVE ON THAT FREQ. I APOLOGIZED AND RPTED CLR OF CLASS D AIRSPACE. I RETURNED TO LITTLEBROOK ARPT AND DID A PRACTICE MISSED APCH I CALLED PEASE TWR AND ASKED PERMISSION TO DO ANOTHER TOUCH AND GO. HE SAID HE WAS UNABLE TO AUTH MY REQUEST UNTIL I GOT MY RADIO FIXED. I FORGOT TO MENTION THAT WHEN PEASE TWR HAD INFORMED ME THAT MY MIKE BUTTON HAD STUCK; HE ASKED ME IF I HAD SEEN A LIGHT SIGN IN THE TWR. I TOLD HIM THAT I HADN'T. IN RETROSPECT; I KNOW I SHOULD HAVE GOTTEN A RESPONSE FROM MY RADIO CALLS; BUT I DIDN'T KNOW I HAD A RADIO PROB AND THEY DON'T ALWAYS RESPOND TO ALL CALLS. I WAS CONCENTRATING ON MY APCH AND LNDGS SO I DIDN'T EVEN LOOK AT THE TWR. IT WAS DAY LIGHT SO I WASN'T LOOKING FOR A LIGHT AND I THOUGHT MY RADIO WAS WORKING. INCIDENTLY THERE WAS NO OTHER ACFT IN THE AREA.
