Narrative:

The training flight was in a 1964 PA-140 with only 1 push-to-talk switch on the left side. The student holds a private pilot certificate and has several hundred hours. We called up west of ixd inbound for touch-and-goes and were told to report a right base. We entered right base and were turning final as I was critiquing his lower than normal approach. The tower was reading an IFR clearance to a baron that was holding short of the runway as we turned on final. I was caught up in the process of instructing my student as we lined up on final when I caught the end of tower's transmission, 'not cleared for the option.' I didn't hear the call sign and asked the student to ask tower if we were cleared to land since I did not have a push-to-talk switch. As I was instructing the student to talk to the tower, I kept my ears pealed for another aircraft with a landing clearance and watched the baron holding short. The student was busy flying the airplane and the tower repeated 'cherokee, did you have a landing clearance? Go around.' I took control of the aircraft and instructed the student to tell tower that we were going around. By this time the student was rather confused and the tower was chastising us for not reporting base. It took several xmissions before my student made it clear to the tower that we realized we forgot to call our base leg and that we didn't have a landing clearance. We did 2 more touch-and-goes and returned to our base airport, ZZZ. There was not a close call or any evasive action taken by any aircraft, the runway was clear the entire time. It was my fault for focusing too much of my attention on the student's lower than normal approach along with my assumption that the private pilot student had made the appropriate base leg call. The chain could have also been broken on final when I caught half the transmission if I had a push-to-talk and didn't have to relay messages through my confused student.

Title: PA28 LNDG IXD IS ISSUED ATC GAR AFTER FAILING TO RPT AS INSTRUCTED ON BASE LEG.

Narrative: THE TRAINING FLT WAS IN A 1964 PA-140 WITH ONLY 1 PUSH-TO-TALK SWITCH ON THE L SIDE. THE STUDENT HOLDS A PVT PLT CERTIFICATE AND HAS SEVERAL HUNDRED HRS. WE CALLED UP W OF IXD INBOUND FOR TOUCH-AND-GOES AND WERE TOLD TO RPT A R BASE. WE ENTERED R BASE AND WERE TURNING FINAL AS I WAS CRITIQUING HIS LOWER THAN NORMAL APCH. THE TWR WAS READING AN IFR CLRNC TO A BARON THAT WAS HOLDING SHORT OF THE RWY AS WE TURNED ON FINAL. I WAS CAUGHT UP IN THE PROCESS OF INSTRUCTING MY STUDENT AS WE LINED UP ON FINAL WHEN I CAUGHT THE END OF TWR'S XMISSION, 'NOT CLRED FOR THE OPTION.' I DIDN'T HEAR THE CALL SIGN AND ASKED THE STUDENT TO ASK TWR IF WE WERE CLRED TO LAND SINCE I DID NOT HAVE A PUSH-TO-TALK SWITCH. AS I WAS INSTRUCTING THE STUDENT TO TALK TO THE TWR, I KEPT MY EARS PEALED FOR ANOTHER ACFT WITH A LNDG CLRNC AND WATCHED THE BARON HOLDING SHORT. THE STUDENT WAS BUSY FLYING THE AIRPLANE AND THE TWR REPEATED 'CHEROKEE, DID YOU HAVE A LNDG CLRNC? GO AROUND.' I TOOK CTL OF THE ACFT AND INSTRUCTED THE STUDENT TO TELL TWR THAT WE WERE GOING AROUND. BY THIS TIME THE STUDENT WAS RATHER CONFUSED AND THE TWR WAS CHASTISING US FOR NOT RPTING BASE. IT TOOK SEVERAL XMISSIONS BEFORE MY STUDENT MADE IT CLR TO THE TWR THAT WE REALIZED WE FORGOT TO CALL OUR BASE LEG AND THAT WE DIDN'T HAVE A LNDG CLRNC. WE DID 2 MORE TOUCH-AND-GOES AND RETURNED TO OUR BASE ARPT, ZZZ. THERE WAS NOT A CLOSE CALL OR ANY EVASIVE ACTION TAKEN BY ANY ACFT, THE RWY WAS CLR THE ENTIRE TIME. IT WAS MY FAULT FOR FOCUSING TOO MUCH OF MY ATTN ON THE STUDENT'S LOWER THAN NORMAL APCH ALONG WITH MY ASSUMPTION THAT THE PVT PLT STUDENT HAD MADE THE APPROPRIATE BASE LEG CALL. THE CHAIN COULD HAVE ALSO BEEN BROKEN ON FINAL WHEN I CAUGHT HALF THE XMISSION IF I HAD A PUSH-TO-TALK AND DIDN'T HAVE TO RELAY MESSAGES THROUGH MY CONFUSED STUDENT.
