Narrative:

While in the tracy traffic pattern, my student and I were working initially with another small aircraft from our flight school. Another small aircraft X entered the traffic pattern, however, we did not hear his call up, as the CTAF frequency was very congested and I believe his call was 'blocked.' he entered the traffic pattern ahead of our aircraft but apparently flew a wide pattern. We did not see him in the haze and we continued around the pattern making the standard position reporting. As we turned final we heard small aircraft X too close and going around. After we landed the small aircraft X began an early crosswind turn and resumed his pattern work. Suggestions: clearly broadcast intentions and make a standard 45 degrees entry. Use landing light in pattern, especially with lowered visibility. Fly the standard traffic pattern, if making a wide pattern specify 'tracy traffic, XXXX wide downwind 29 tracy.' keep a constant watch for traffic.

Title: INSTRUCTOR WITH SPI HAD CLOSE PROX WITH SECOND ACFT IN UNCTLED TFC PATTERN.

Narrative: WHILE IN THE TRACY TFC PATTERN, MY STUDENT AND I WERE WORKING INITIALLY WITH ANOTHER SMA FROM OUR FLT SCHOOL. ANOTHER SMA X ENTERED THE TFC PATTERN, HOWEVER, WE DID NOT HEAR HIS CALL UP, AS THE CTAF FREQ WAS VERY CONGESTED AND I BELIEVE HIS CALL WAS 'BLOCKED.' HE ENTERED THE TFC PATTERN AHEAD OF OUR ACFT BUT APPARENTLY FLEW A WIDE PATTERN. WE DID NOT SEE HIM IN THE HAZE AND WE CONTINUED AROUND THE PATTERN MAKING THE STANDARD POS RPTING. AS WE TURNED FINAL WE HEARD SMA X TOO CLOSE AND GOING AROUND. AFTER WE LANDED THE SMA X BEGAN AN EARLY XWIND TURN AND RESUMED HIS PATTERN WORK. SUGGESTIONS: CLRLY BROADCAST INTENTIONS AND MAKE A STANDARD 45 DEGS ENTRY. USE LNDG LIGHT IN PATTERN, ESPECIALLY WITH LOWERED VISIBILITY. FLY THE STANDARD TFC PATTERN, IF MAKING A WIDE PATTERN SPECIFY 'TRACY TFC, XXXX WIDE DOWNWIND 29 TRACY.' KEEP A CONSTANT WATCH FOR TFC.
