Narrative:
After talking to the pilot and flight instructor of the other aircraft, it was apparent that we both did not see or were aware of each other's presence. I was radioing my position and intentions on the unicom frequency and the flight instructor of the other aircraft said that he was on the center frequency. (I am not aware if the other aircraft was in radar contact.) I asked him why he was not monitoring the unicom frequency. His reply was that he had only 1 working transmitter and that he did not hear our calls. The situation happened over the OM, I was headed inbound on the ILS. I instructed my student to put the gear down and set the power for the final descent. Just as I looked inside to monitor my student's progress configuring the airplane, my student and I saw a flash pass beneath us going the opposite direction. There was no time to react to the situation. Continuing the ILS we heard the other aircraft call outbound on the procedure turn. We continued to land and secure the aircraft on the ground. It is my feeling that because we both were on different frequencys, we did not have the aid of the radio to help us see and avoid. We both had every right to be in the airspace and flying the approach, because one was talking to center and the other was not does not give right of way to another airplane.

Title: INSTRUCTOR WITH SPI ON ILS APCH AT NON TWR ARPT HAS NMAC WITH ANOTHER INSTRUCTOR WITH STUDENT WHO IS OUTBOUND ON THE PROC TURN.
Narrative: AFTER TALKING TO THE PLT AND FLT INSTRUCTOR OF THE OTHER ACFT, IT WAS APPARENT THAT WE BOTH DID NOT SEE OR WERE AWARE OF EACH OTHER'S PRESENCE. I WAS RADIOING MY POS AND INTENTIONS ON THE UNICOM FREQ AND THE FLT INSTRUCTOR OF THE OTHER ACFT SAID THAT HE WAS ON THE CTR FREQ. (I AM NOT AWARE IF THE OTHER ACFT WAS IN RADAR CONTACT.) I ASKED HIM WHY HE WAS NOT MONITORING THE UNICOM FREQ. HIS REPLY WAS THAT HE HAD ONLY 1 WORKING XMITTER AND THAT HE DID NOT HEAR OUR CALLS. THE SIT HAPPENED OVER THE OM, I WAS HEADED INBOUND ON THE ILS. I INSTRUCTED MY STUDENT TO PUT THE GEAR DOWN AND SET THE PWR FOR THE FINAL DSCNT. JUST AS I LOOKED INSIDE TO MONITOR MY STUDENT'S PROGRESS CONFIGURING THE AIRPLANE, MY STUDENT AND I SAW A FLASH PASS BENEATH US GOING THE OPPOSITE DIRECTION. THERE WAS NO TIME TO REACT TO THE SIT. CONTINUING THE ILS WE HEARD THE OTHER ACFT CALL OUTBOUND ON THE PROC TURN. WE CONTINUED TO LAND AND SECURE THE ACFT ON THE GND. IT IS MY FEELING THAT BECAUSE WE BOTH WERE ON DIFFERENT FREQS, WE DID NOT HAVE THE AID OF THE RADIO TO HELP US SEE AND AVOID. WE BOTH HAD EVERY RIGHT TO BE IN THE AIRSPACE AND FLYING THE APCH, BECAUSE ONE WAS TALKING TO CTR AND THE OTHER WAS NOT DOES NOT GIVE RIGHT OF WAY TO ANOTHER AIRPLANE.
