While giving flight training at visalia, ca, and on an ILS approach to runway 30 at that airport, our aircraft was on the localizer-G/south, approximately 300' AGL, when a red small aircraft was first noticed higher than our aircraft and turning from base leg to final approach and descending. I immediately took the flight controls and executed a right turn to avoid the above mentioned aircraft. It appeared that the small aircraft overshot the final approach course to me and one of the students that was in the back of our aircraft, which made it extremely difficult to avoid hitting that aircraft. Although our aircraft was receiving traffic advisories from fresno approach control from time to time, there was no radar coverage due to our altitude. I returned and landed our aircraft visalia airport to find the small aircraft and pilot. I talked with the pilot and he stated he did not see me (our aircraft). I stated to him that we announced our position/intentions over the OM inbound and 3 mi final. He stated he did not hear us at all. Then, stated he was transmitting/receiving on frequency 122.8. I told him visalia was on 123.0. He then stated the WAC chart he was using said 122.8.

Title: CLOSE PROX ACR-SMT ON TRAINING FLT AND GA-SMA.
Narrative: WHILE GIVING FLT TRNING AT VISALIA, CA, AND ON AN ILS APCH TO RWY 30 AT THAT ARPT, OUR ACFT WAS ON THE LOC-G/S, APPROX 300' AGL, WHEN A RED SMA WAS FIRST NOTICED HIGHER THAN OUR ACFT AND TURNING FROM BASE LEG TO FINAL APCH AND DSNDING. I IMMEDIATELY TOOK THE FLT CTLS AND EXECUTED A RIGHT TURN TO AVOID THE ABOVE MENTIONED ACFT. IT APPEARED THAT THE SMA OVERSHOT THE FINAL APCH COURSE TO ME AND ONE OF THE STUDENTS THAT WAS IN THE BACK OF OUR ACFT, WHICH MADE IT EXTREMELY DIFFICULT TO AVOID HITTING THAT ACFT. ALTHOUGH OUR ACFT WAS RECEIVING TFC ADVISORIES FROM FRESNO APCH CTL FROM TIME TO TIME, THERE WAS NO RADAR COVERAGE DUE TO OUR ALT. I RETURNED AND LANDED OUR ACFT VISALIA ARPT TO FIND THE SMA AND PLT. I TALKED WITH THE PLT AND HE STATED HE DID NOT SEE ME (OUR ACFT). I STATED TO HIM THAT WE ANNOUNCED OUR POS/INTENTIONS OVER THE OM INBND AND 3 MI FINAL. HE STATED HE DID NOT HEAR US AT ALL. THEN, STATED HE WAS TRANSMITTING/RECEIVING ON FREQ 122.8. I TOLD HIM VISALIA WAS ON 123.0. HE THEN STATED THE WAC CHART HE WAS USING SAID 122.8.
