Narrative:

Our company aircraft was approaching opa locka airport using mia approach. We were given 128.6 for approach control. We were close to the airport (high) at 4000' medium large transport when we realized nobody was receiving our xmissions (on 128.6). We kept hearing mia call us and we responded immediately with heading and altitude changes, however they could not hear us. At this time we both started to call up mia thinking we had a possible radio failure. After a quick analyzation of cockpit microphone and radio checks, we went back to the last assigned frequency. We found out at that time that the frequency 128.6 we heard mia calling on but could not receive us on was due to an inoperative receiver on mia's part. When we finally reached a controller on another frequency, they were questioning our altitude/ heading as though we were causing a problem (traffic related). During this flight the last 10 mins were getting a little stressful on both our part and mia. Reason for report: possible heading and altitude changes unclear between aircraft and mia approach. Disagreement between controllers on our heading and altitude. Corrective action: immediately called back on last assigned frequency, or tried another frequency for approach and advise sooner of our situation. Our aircraft was close in, high and had little time for being assigned an inoperative frequency. Mia said that this frequency was OTS.

Title: CPR MDT UNABLE TO CONTACT MIA APCH CTL ON ASSIGNED FREQ.

Narrative: OUR COMPANY ACFT WAS APCHING OPA LOCKA ARPT USING MIA APCH. WE WERE GIVEN 128.6 FOR APCH CTL. WE WERE CLOSE TO THE ARPT (HIGH) AT 4000' MLG WHEN WE REALIZED NOBODY WAS RECEIVING OUR XMISSIONS (ON 128.6). WE KEPT HEARING MIA CALL US AND WE RESPONDED IMMEDIATELY WITH HDG AND ALT CHANGES, HOWEVER THEY COULD NOT HEAR US. AT THIS TIME WE BOTH STARTED TO CALL UP MIA THINKING WE HAD A POSSIBLE RADIO FAILURE. AFTER A QUICK ANALYZATION OF COCKPIT MIC AND RADIO CHKS, WE WENT BACK TO THE LAST ASSIGNED FREQ. WE FOUND OUT AT THAT TIME THAT THE FREQ 128.6 WE HEARD MIA CALLING ON BUT COULD NOT RECEIVE US ON WAS DUE TO AN INOP RECEIVER ON MIA'S PART. WHEN WE FINALLY REACHED A CTLR ON ANOTHER FREQ, THEY WERE QUESTIONING OUR ALT/ HDG AS THOUGH WE WERE CAUSING A PROB (TFC RELATED). DURING THIS FLT THE LAST 10 MINS WERE GETTING A LITTLE STRESSFUL ON BOTH OUR PART AND MIA. REASON FOR RPT: POSSIBLE HDG AND ALT CHANGES UNCLEAR BTWN ACFT AND MIA APCH. DISAGREEMENT BTWN CTLRS ON OUR HDG AND ALT. CORRECTIVE ACTION: IMMEDIATELY CALLED BACK ON LAST ASSIGNED FREQ, OR TRIED ANOTHER FREQ FOR APCH AND ADVISE SOONER OF OUR SITUATION. OUR ACFT WAS CLOSE IN, HIGH AND HAD LITTLE TIME FOR BEING ASSIGNED AN INOP FREQ. MIA SAID THAT THIS FREQ WAS OTS.
